1. Introduction

The Philippines is an archipelago of 7,107 islands with a land area of 299,740 sq. kilometers.  It is surrounded by the Pacific Ocean on the East, South China Sea on the North and the West and the Celebes Sea on the South. This comprises the National Territory of the Philippines. Article I of the 1987 Constitution provides that the "national territory comprises the Philippine archipelago, with all the islands and waters embraced therein and all other territories which the Philippines has sovereignty or jurisdiction."


The Filipino culture was molded over more than a hundred ethnic groups consisting of 91% Christian Malay, 4% Muslim Malay, 1.5% Chinese and 3% others.  As of the August 2007 national census, the population of the Philippines has increased to 88.57 million and is estimated to reach 92.23 million in 2009.  The census is scheduled to be undertaken this 2009.


Filipino is the national language (1987 Constitution, Art. XIV, sec. 6).  However, Filipino and English are the official languages for the purpose of communication and instruction (Art. XIV, sec 7).  There are several dialects or regional languages spoken throughout the different islands of the country, but there are eight major dialects, which include Bicolano, Cebuano, Hiligaynon or Ilongo,   Ilocano,  Pampango, Pangasinense, Tagalog, and Waray.


There are two major religions of the country: Christianity and Islam.  Christianity, more particularly Catholicism, is practiced by more than 80% of the population. It was introduced by Spain in 1521. The Protestant religion was introduced by American missionaries.


Aglipay, or the Philippine Independent Church, and the Iglesia ni Kristo are two Filipino independent churches.  Other Christian religious organizations like the El Shaddai,  Ang Dating Daan, and  'Jesus is Lord' have been established and have a great influence to the nation.


The Constitution of the Philippines specifically provides that the separation of Church and State is inviolable. (Constitution (987), Art. II, sec.6). However, religion has a great influence in the legal system of the Philippines. For the Muslim or Islamic religion, a special law, the Code of Muslim Personal Laws (Presidential Decree no. 1083), was promulgated and special courts were established, the Shari’a courts. The Church has affected the present political system.  A priest had to take leave as a priest when he was elected governor of a province in Region 3.   A movement was even started to be able to choose the President of the Philippines and other government officials in the May 2009 national election.



2. Political Structure

The Constitution is the fundamental law of the land. The present political structure of the Philippines was defined by the 1987 Constitution, duly ratified in a plebiscite held on February 2, 1987. There is a move now in  Congress which was started at the House of Representatives to revise/amend the present Constitution.  One of the major problems to be resolved by both Houses of Congress is the mode or method in revising/amending the Constitution.


The 1987 Constitution provides that the Philippines is a democratic and republican state where sovereignty resides in the people and all government authority emanates from them (Article II, section 1). 


3. Government Structure

The government structure differs as one goes through the history of the Philippines, which may be categorized as follows:  a) Pre-Spanish; b). Spanish period; c). American period; d). Japanese period; e). Republic; and f). Martial Law Period


a) Pre-Spanish (before 1521)

The Barangays or independent communities were the unit of government structures before Spain colonized the Philippines. The head of each barangay was the Datu.  He governs the barangays using native rules which are customary and unwritten.  There were two codes during this period: the Maragtas Code issued by Datu Sumakwel of Panay Island and the Code of Kalantiao issued by Datu Kalantiano in 1433.  The existence of these codes is questioned by some historians.


Just like many ancient societies, trial by ordeal was practiced.


b) Spanish period (1521-1898)

The Spanish period can be traced from the time Magellan discovered the Philippines when he landed on Mactan Island (Cebu) on March 16, 1521. Royal decrees, Spanish laws, and/or special issuances of special laws for the Philippines were extended to the Philippines from Spain by the Spanish Crown through the councils.  The chief legislator is the governor-general who exercises legislative functions by promulgating executive decrees, edicts or ordinances with the force of law. The Royal Audencia, or Spanish Supreme Court, in the Philippines also exercised legislative functions when laws are passed in the form of autos accordados.  Melquiades Gamboa, in his book entitled “ An Introduction to Philippine Law” (7th ed, 1969), listed the most prominent laws in this period: Fuero Juzgo, Fuero Real, Las Siete Partidas, Leyes de Toros, Nueva Recopilacion de las Leyes de Indias and the Novisima Recopilacion.  Some of these laws were also in force in other Spanish colonies.  Laws in force at the end of the Spanish rule in 1898 are as follows: Codigo Penal de 1870, Ley Provisional para la Aplicaciones de las Dispociciones del Codigo Penal en las Islas Filipinas, Ley de Enjuciamento Criminal, Ley de Enjuciameniento Civil, Codigo de Comercio, Codigo Civil de 1889, Ley Hipotecaria, Ley de Minas, Ley Notarial de 1862, Railway Law of 1877, Law of Foreigners for Ultramarine Provinces and the Code of Military Justice.  Some of these laws remained in force even during the early American period and/or until Philippine laws were promulgated.


In between the Spanish and the American period is what Philippine historians consider the first Philippine Republic.  This was when General Emilio Aguinaldo proclaimed the Philippine Independence in Kawit , Cavite on June 12, 1898. The Malolos Congress also known as Assembly of the Representatives, which can be considered as revolutionary in nature, was convened on September 15, 1898.  The first Philippine Constitution, the Malolos Constitution was approved on January 20, 1899. General Emilio Aguinaldo was the President and Don Gracio Gonzaga as the Chief Justice. A Republic, although with de facto authority, was in force until the start of the American Sovereignty when the Treaty of Paris was signed on December 10, 1898.


c) American period (1898-1946)

The start of this period can be traced after the Battle of Manila Bay when Spain ceded the Philippines to the United States upon the signing of the Treaty of Paris on December 10, 1898.  A military government was organized with the military governor as the chief executive exercising executive, legislative and judicial functions.  Legislative function was transferred to the Philippine Commission in 1901 which was created by the United States President as commander-in-chief of the Armed forces and later ratified by the Philippine Bill of 1902.  This same Bill provided for the establishment of the First Philippine Assembly which convened on October 16, 1907.  The Jones law provided for the establishment of a bicameral legislative body on October 16, 1916, composed of the Senate and the House of Representatives. 


The United States Constitution was recognized  until the  promulgation of the Philippine Constitution  on February 8, 1935, signed by U.S. President Franklin Delano Roosevelt  on March 23, 1935 and ratified at a  plebiscite held on May 14, 1935.


The organic laws that governed the Philippines during this period were: President McKinley’s Instruction to the Second Philippine Commission on April 7, 1900; Spooner Amendment of 1901; Philippine Bill of 1902; Jones Law of 1916 and the Tydings McDuffie Law of May 1, 1934.  The later law is significant for it allowed the establishment of a Commonwealth government and the right to promulgate its own Constitution. The 1935 Constitution initially changed the legislative system to a unicameral  system.  However, the bicameral system was restored pursuant to the 1940 Constitutional amendment. The Commonwealth government is considered as a transition government for ten years before the granting of the Philippine independence.  Cayetano Arellano was installed as the first Chief Justice in 1901. The Majority of the Justices of the Philippine Supreme Court were Americans. Decisions rendered by the Supreme Court of the Philippines were appealed to the United States Supreme Court, which were reported in the United States Supreme Court Reports.


Manuel L. Quezon and Sergio  Osmeña were elected as President and Vice-President respectively during the September 14, 1935 elections. In this election, President Quezon won over General Emilio Aguinaldo and Bishop Gregorio Aglipay, the President of the First Philippine Republic (1898) and the head of the Aglipayan church, respectively. This Commonwealth government went into exile in Washington DC during the Japanese period from May 13, 1942 to October 3, 1944.  President Manuel L. Quezon died on August 1, 1944 and was succeeded by President Sergio Osmena who brought back the government to Manila on February 28, 1945.


d) Japanese period (1941-1944)

The invasion of the Japanese forces when Clark Field, an American military airbase in Pampanga, was bombed on December 8, 1941, marked the start of the Japanese period which lasted for three years. A Japanese Republic was established with Jose P. Laurel as its President. Jose Yulo was the Chief Justice of the Supreme Court.  This period was considered as a military rule by the Japanese Imperial Army.  The 1943 Constitution was ratified by a special national convention of the Kapisanan sa Paglilingkod ng Bagong Pilipinas (KALIBAPI).   This period  lasted for three years and  ended in 1944 with the defeat of the Japanese forces.


e) Republic period (1946-1972)

July 4, 1946 was the inauguration of Philippine independence.  A Philippine Republic was born.  A republic means a government by the people and sovereignty resides in the entire people as a body politic.   The provisions of the 1935 Constitution defined the government structure which provided for the establishment of three co-equal branches of government.  Executive power rests in the President, legislative power in two Houses of Congress and judicial power in the Supreme Court, and inferior courts.  Separation of powers is recognized. 


Efforts to amend the 1935 Constitution started on August 24, 1970 with the approval of Republic Act No. 6132 where 310 delegates were elected on November 10, 1970.  On June 1, 1971, the Constitutional Convention met.  While it was still in session, President Ferdinand E. Marcos declared Martial Law on September 21, 1972.  The Constitutional Convention completed the draft Constitution on November 29, 1972.  It was submitted for ratification through citizens’ assemblies on January 17, 1973.  This is known as the 1973 Constitution.


f) Martial Law Period (1972-1986).

The Congress of the Philippines was abolished when Martial Law was declared on September 21, 1972. The Martial Law period was governed by the 1973 Constitution which established a parliamentary form of government.  Executive and legislative powers were merged and the Chief Executive was the Prime Minister who was elected by majority of all members of the National Assembly (Parliament). The Prime Minister had the power to advise the President.  The President is the symbolic head of state.  This parliamentary government was never implemented due to the transitory provision of the 1973 Constitution.  Military tribunals were also established. Amendments to the Constitution were made wherein by virtue of amendment No. 3, the powers of the President and the Prime Minister were merged into the incumbent President Ferdinand E. Marcos.  Amendment No. 6 authorized President Marcos to continue exercising legislative powers until Martial law is in effect.  Amendment No. 7 provided for the barangays as the smallest political subdivision and the sanggunians, or councils.  The 1981 amendment introduced the modified presidential/parliamentary system of government of the Philippines. The President shall be elected by the people for a term of six years while the Prime Minister shall be elected by a majority of the Batasang Pambansa (Parliament) upon the nomination of the President.  He was the head of the Cabinet and had supervision over all the ministries.


Proclamation No. 2045 (1981) lifted Martial Law and abolished military tribunals.  Elections were held on June 16, 1981 and President Marcos was re-elected into office as President.  The constitution was again amended in 1984 and a plebiscite was held on January 27, 1984 pursuant to Batas Pambansa Blg. 643 (1984).  Elections were held on May 14, 1984 for the 183 elective seats in the 200 member of the Batasang Pambansa.


An impeachment  resolution by 57 members of the opposition was filed against President Marcos but was dismissed.  A special presidential election, popularly known as Snap Election, was called by President Marcos on November 3, 1985 and was held on February 7, 1986.  The National Movement for Free Elections, or NAMFREL, results showed that Corazon Aquino led by over a million votes.  However, the Batasang Pambansa declared that Ferdinand E. Marcos and Arturo M. Tolentino won over Corazon C. Aquino and Salvador H. Laurel as President and Vice-President, respectively.  This event led to the People Power revolution, which ousted President Marcos on February 25, 1986.


g) Republic Revival (1986-present)

The Republic period was revived after the bloodless revolution popularly known as People Power or the EDSA Revolution. 


Corazon C. Aquino and Salvador H. Laurel took their oath of office as President and Vice President of the Philippine Republic on February 25, 1986.  Proclamation No. 1 (1986) was promulgated wherein the President and the Vice President took power in the name and by the will of the Filipino people.  Proclamation No. 3 (1986) adopted as the Provisional Constitution or Freedom Constitution, provided for a new government. 


A Constitutional Commission was constituted by virtue of Article V of the Provisional Constitution and Proclamation No. 9 (1986).  The Constitutional Commission, composed of 48 members, was mandated to draft a Constitution.  After 133 days, the draft constitution was submitted to the President on October 15, 1986 and ratified by the people in a plebiscite held on February 2, 1987.  Under the transitory provision of the 1987 Constitution, the President and Vice President elected in the February 7, 1986 elections were given a six year term of office until June 30, 1992.  Congressional elections were held on May 11, 1987.  The Republican form of government was officially revived when the 1987 Constitution was ratified and Congress was convened in 1987.   Legislative enactments again rested in the Congress.  Republic Acts were again issued by Congress, the number of which took off from the last number used before Martial Law was declared.  The numbering of Republic Acts continued from the number last used before Martial Law (Republic Act No. 6635 (1972) and Republic Act No. 6636 (1987). The Republic form of government by virtue of the 1987 Constitution was the same type of republican  government prior to Martial law  by virtue of the 1935 Constitution with three co-equal branches: Executive, Legislative and the Judiciary.


The Philippines once again became a Republic by virtue of the 1987 Constitution.  The same type of republican form of government prior to Martial law was established with three co-equal branches were organized, Executive, Legislative and the Judiciary. 


Aside from the three co-equal branches, the following are other offices in government:

a)  government financial institutions and government-owned and controlled corporations.


3.1 Executive Branch

The President is vested with the executive power. (Art. VII, sec. 1, 1987 Constitution). The President is both the Chief of State (head of government) and the Commander-in-Chief of all the Armed Forces of the Philippines (Art. VII, sec. 18).  Since 1898 when the First Philippine Republic was established, the Philippines has had thirteen (13) Presidents.


The other members of the Executive Branch are the Vice-President and the Heads of Executive Departments or Cabinet members.


The following are the Departments under the Executive Branch:



There are specific bureaus and offices directly under the Office of the President.


Both the President and the Vice-President are elected by direct vote of the Filipino people for a term of six years. The President is not eligible for a reelection while the Vice President cannot serve for more than two terms.  Congress is empowered to promulgate rules in the canvassing of certificates of election.  The Supreme Court sitting en banc is the sole judge of all election contests relating to their election, returns and qualifications (Art VII, sec. 4).  The Supreme Court en banc thus acts as the Presidential Electoral Tribunal.  The Supreme Court promulgated the 2005 Rules on the Presidential Tribunal (A.M. No. 05-11-06-SC). Both may be removed from office by impeachment (Art. XI sec. 2) to be initiated by the House of Representatives (Art. XI, sec, 3) and tried and decided by the Senate (Art. XI, sec, 3 (6)). The Cabinet members are nominated by the President, subject to the confirmation of the Commission on Appointments (Art. VII, sec, 16) which consists of the President of the Senate, as ex- officio Chairman, twelve Senators and twelve members of the House of Representatives (Art. VI, sec. 1).


Cabinet members are nominated by the President, subject to the confirmation of the Commission on Appointments (Art. VII, sec, 16), which consists of the President of the Senate, as ex officio Chairman, twelve Senators and twelve members of the House of Representatives (Art. VI, sec. 1).

The President exercises control over all the executive departments, bureaus and offices (Art. VI, sec, 17).


3.2 Legislative Department

Legislative power is vested in the Congress of the Philippines, consisting of the Senate and the House of Representatives (Art. VI, sec. 1).  History has provided that the legislative structure has undergone numerous changes. To better appreciate its transition, the Philippine Senate has provided a detailed account and is found on Senate website.


Senate of the Philippines

The Senate is composed of twenty four (24) Senators who are elected at large by qualified voters who serve for a term of not more than six (6) years.  No Senator may be elected for more than two consecutive terms. (Art VI, sec. 4). The Senate is led by the Senate President, Pro Tempore, Majority Leader and the Minority Leader.  The Senate President is elected by majority vote of its members. There are thirty six (36) permanent committees and five (5) oversight committees.  The sole judge of contests relating to election, returns and qualifications of members of the Senate rests with the Senate Electoral Tribunal (SET) which is composed of nine members, three of whom are Justices of the Supreme Court and six members of the Senate. (Art. VI, sec. 17).  The Senate Electoral Tribunal has approved on November 12, 2003 its Revised Rules.


House of Representatives

The House of Representatives is composed of not more than two hundred fifty (250) members, elected by legislative districts for a term of three years. No  representative shall serve for more than three consecutive terms.  The party-list representatives, who come from registered national, regional and sectional parties and organizations, shall constitute twenty percent (20%) of the total number of representatives. The election of party-list representatives was by virtue of the Republic Act No. 7941 which was approved on March 3, 1995.  In a recent  decision of the Supreme Court penned by Justice Antonio T. Carpio on April 21, 2009, Barangay Association for National Advancement and Transparency (BANAT) v. Commission on Elections (G.R. No. 17971) and Bayan Muna, Advocacy for Teacher Empowerment  Through Action, Cooperation and Harmony Towards Educational Reforms, Inc. and Abono (G.R. No. 179295), Republic Act No. 7941 was  declared unconstitutional with regards to the two percent threshold in the distribution of additional party-list seats.  The Court in this decision provided a procedure in the allocation of additional seats under the Party-List System. Major political parties are disallowed from participating in party-list elections


 The officials of the House are the Speaker of the House, Deputy Speaker for Luzon, Deputy Speaker for Visayas, Deputy Speaker for Mindanao, Majority Leader, and Minority Leader. The Speaker of the House is elected by majority vote of its members. There are fifty seven (57) standing committees and sixteen (16) special committees of the House of Representatives. The sole judge of contests relating to election, returns and qualifications of members of the House of Representatives rests with the House of Representatives  Electoral Tribunal (HRET)  which is composed of  nine members, three of whom are Justices of the Supreme Court and six members of the Senate.(Art. VI, sec. 17).  The House of Representatives Electoral Tribunal adopted its 1998 Internal Rules on  March 24, 1998..


3.3 Judicial System


Organizational Chart of the whole Judicial System and those of each type of Court is available in 2002 Revised Manual of Clerks of Court. Manila: Supreme Court, 2002.  Organizational Chart was amended due to the passage of Republic Act No. 9282 (CTA)


Judicial power rests with the Supreme Court and the lower courts, as may be established by law (Art. VIII, sec. 1).  The judiciary enjoys fiscal autonomy.  Its appropriation may not be reduced by the legislature below the appropriated amount the previous year (Art. VIII, sec. 2).  The Rules of Court of the Philippines as amended and the rules and regulations issued by the Supreme Court define the rules and procedures of the Judiciary. These rules and regulations are in the form of Administrative Matters, Administrative Orders, Circulars, Memorandum Circulars, Memorandum Orders and OCA Circulars.  To inform the members of the Judiciary, legal profession and the public of these rules and regulations, the Supreme Court disseminates this rules and regulations to all courts, publishes important ones in newspapers of general circulation, prints in book or pamphlet form and now downloads them in the Supreme Court website and the Supreme Court E-Library website.


Department of Justice Administrative Order No. 162 dated August 1, 1946 provided for the Canon of Judicial Ethics.  Supreme Court of the Philippines promulgated a new Code of Judicial Conduct for the Philippine Judiciary effective June 1, 2004 (A.M. No. 03-05-01-SC), which was published in two newspapers of general circulation on May 3, 2004 (Manila Bulletin & Philippine Star) and available on its website and the Supreme Court E-Library website.



The Supreme Court promulgated on June 21, 1988 the Code of Professional Responsibility for the legal profession.  The draft was prepared by the Committee on Responsibility, Discipline and Disbarment of the Integrated Bar of the Philippines.


A Code of Conduct for Court Personnel (A.M. No. 03-06-13-SC) was adopted on April 13, 2004,   effective June 1, 2004, published  in two newspapers of general circulation  on April 26, 2004 (Manila Bulletin & Philippine Star) and available at its website and the Supreme Court E-Library  website.



Supreme Court of the Philippines

The barangay chiefs exercised judicial authority prior to the arrival of Spaniards in 1521. During the early years of the Spanish period, judicial powers were vested upon Miguel Lopez de Legaspi, the first governor general of the Philippines where he administered civil and criminal justice under the Royal Order of August 14, 1569.


The Royal Audencia was established on May 5, 1583, composed of a president, four oidores (justices) and a fiscal.  The Audencia exercised both administrative and judicial functions.  Its functions and structure were modified in 1815 when its president was replaced by a chief justice and the number of justices was increased.  It came to be known as the Audencia Territorial de Manila with two branches, civil and criminal.  Royal Decree issued July 24, 1861 converted it to a purely judicial body wherein its decisions were appealable to the Supreme Court of the Philippines to the Court of Spain in Madrid.  A territorial Audencia in Cebu and Audencia for criminal cases in Vigan were organized on February 26, 1898.   The Audencias were suspended by General Wesley Merrit when a military government was established after Manila fell to American forces in 1898.  Major General Elwell S. Otis re-established the Audencia on May 29, 1899 by virtue of General Order No. 20.  Said Order provided for six Filipino members of the Audencia.  Act No. 136  abolished the Audencia  and established the present Supreme Court on June 11, 1901 with Cayetano Arellano as the first Chief Justice together with associate justices, the majority of whom were American.  Filipinization of the Supreme Court started only during the Commonwealth, 1935. Administrative Code of 1917 provided for a Supreme Court with a Chief Justice and eight associate Justices.  With the ratification of the 1935 Constitution, the membership was increased to 11 with two divisions of five members each.  The 1973 Constitution further increased its membership to 15 with two (2) divisions.


Pursuant to the provisions of the 1987 Constitution, the Supreme Court is composed of a Chief Justice and fourteen Associate Justices who shall serve until the age of seventy (70).  The Court may sit En Banc or in its three (3) divisions composed of five members each.  A vacancy must be filled up by the President within ninety (90) days of occurrence.


Article VIII, sec. 4 (2) explicitly provides for the cases that must be heard En Banc and sec. 4 (3)  for cases that may be heard by divisions. (Constitution, Art. VIII, sec. 4, par.1) Judiciary Reorganization Act  of 1980 transferred from the Department of Justice to the  Supreme Court   the administrative supervision of all courts and their personnel.  This was affirmed by  Art. VIII, sec. 6 of the 1987 Constitution.  To effectively discharge this constitutional mandate, The Office of the Court Administrator (OCA)  was created under Presidential Decree No. 828, as mended by Presidential Decree No. 842, and  and its functions further strengthened by a  Resolution of the Supreme Court En Bans dated October 24, 1996.  Its principal function is the supervision and administration of the lower courts throughout the Philippines  and all their personnel.  It reports and recommends to the Supreme Court all actions that affect the lower court management.  The OCA is headed by the Court Administrator, three (3) Deputy Court Administrators and  three (3) Assistant Court Administrators.


According to the 1987 Constitution, Art. VIII, sec. 5, The Supreme Court exercises the following powers:



The Supreme Court has adopted and promulgated the Rules of Court for the protection and enforcement of constitutional rights, pleadings and practice and procedure in all courts, and the admission in the practice of law.  In line with this mandate of the Rules of Court and extrajudicial killing and disappearances, the Supreme Court passed two important Resolutions: the Rule on the Writ of Amparo, approved on September 25, 2007 and effective on October 24, 2007,  and the Rule on the Writ of Habeas Data, approved on January 22, 2008 and effective February 2, 2008. Amendments are promulgated through the Committee on Revision of Rules.  The Court also issues administrative rules and regulations in the form of court issuances and the Supreme Court E-Library website.



The Judicial and Bar Council was created by virtue of Art. VIII, sec. 8. under the supervision of the Supreme Court.  Its principal function is to screen prospective appointees to any judicial post. The Judicial and Bar Council has promulgated on October 31, 2000 its Rules (JBC-009) in the performance of its function.  It is composed of the Chief Justice as ex-officio Chairman, the Secretary of Justice and representatives of Congress as ex-officio members, a representative of the Integrated Bar, a professor of law, a retired member of the Supreme Court and a representative of the private sector as members.


The Philippine Judicial Academy (PHILJA) is the “training school for justices, judge, court personnel, lawyers and aspirants to judicial posts.”   It was originally created by the Supreme Court on March 16, 1996 by virtue of Administrative Order No. 35-96 and was institutionalized on February 26, 1998 by virtue of Republic 8557.  It is an important component of the Supreme Court for its important mission on judicial education.  No appointee to the Bench may commence the discharge his adjudicative function without completing the prescribed court in the Academy.  Its organizational structure and administrative set-up are provided for by the Supreme Court in its En Banc resolution ( Revised A.M. No. 01-1-04-sc-PHILJA).


The Philippine Mediation Center was organized “pursuant to Supreme Court “en banc” Resolution A.M. No. 01-10-5-SC-PHILJA, dated October 16, 2001, and in line with the objectives of the Action Program for Judicial Reforms (APJR) to decongest court dockets, among others, the Court prescribed guidelines in institutionalizing and implementing the mediation program in the Philippines. The same resolution designated the Philippine Judicial Academy as the component unit of the Supreme Court for Court-Annexed Mediation and other Alternative Dispute Resolution (ADR) Mechanisms, and established the Philippine Mediation Center (PMC).”


Mandatory Continuing Legal Education Office was organized to implement the rules on Mandatory Continuing Legal Education for members of the Integrated Bar of the Philippines (B.M. No. 850 – “Mandatory Continuing Legal Education (MCLE)). It holds office in the Integrated Bar of the Philippines main office.



Court of Appeals

Commonwealth Act No. 3 (December 31, 1935), pursuant to the 1935 Constitution (Art VIII, sec. 1), established the Court of Appeals.  It was formally organized on February 1, 1936 and was composed of eleven justices with Justice Pedro Concepcion as the first Presiding Justice.  Its composition was increased to 15 in 1938 and further increased to 17 in 1942 by virtue of Executive Order No. 4.  The Court of Appeals was regionalized in the later part of 1944 when five District Court of Appeals were organized for Northern, Central and Southern Luzon, for Manila and for Visayas and Mindanao.  It was abolished by President Osmena in 1945, pursuant to Executive Order No. 37 due to the prevailing abnormal conditions.  However, it was re-established on October 4, 1946 by virtue of Republic Act No. 52 with a Presiding Justice and fifteen (15) Associate Justices.  Its composition was increased by the following enactments: Republic Act No. 1605 to eighteen (18); Republic Act No. 5204 to twenty-four (24); Presidential Decree No. 1482 to one (1) Presiding Justice and thirty-four (34) Associate Justices; Batas Pambansa Blg. 129 to fifty (50); Republic Act No. 8246 to sixty-nine (69). With Republic Act No. 8246, the Court of Appeals in Cebu, and Cagayan de Oro were established. 


Batas Pambansa Blg. 129  changed the name of the Court of  Appeals to Intermediate Appellate Court.  Executive Order No. 33  brought back  its name to Court of Appeals.


Section 9 of Batas Pambansa Blg. 129 as amended by Executive Order No. 33 and Republic Act No. 7902 provides for the jurisdiction of the Court of Appeals as follows:



The Supreme Court, acting on the recommendation of the Committee on Revision of the Rules of Court, resolved to approve the 2002 Internal Rules of the Court of Appeals (A.M. No. 02-6-13-CA) and amended by a resolution of the Court En Banc on July 13, 2004  (A.M. No. 03-05-03-SC).


Pursuant to Republic Act No. 9372 otherwise known as the Human Security Act of 2007, the Chief Justice issued Administrative Order No. 118-2007, designating the First, Second and Third Divisions of the Court of Appeals to handle cases involving the crimes of terrorism  or conspiracy to commit terrorism and all other matters incident to the said crimes emanating from the Metropolitan Manila and Luzon.  For those emanating from Visayas, all divisions of the Court of Appeals stationed in Cebu are designated to handle these cases while the Court of Appeals stationed in Cagayan De Oro will handle cases from Mindanao.



The Anti-Graft Court, or Sandiganbayan, was created to maintain integrity, honesty and efficiency in the bureaucracy and weed out misfits and undesirables in government service (1973 Constitution (Art. XIII, sec. 5) and 1987 Constitution (Art. XI, sec. 4)).  It was restructured by Presidential Decree No. 1606 as amended by Republic Act No. 8249.  It is composed of a Presiding Justice and fourteen (14) Associate Justices still in five Divisions of three (3) Justices each.    


The Supreme Court, acting on the recommendation of  the Committee on  Revision of the Rules of Court, resolved  with modification  the Revised Internal Rules of the Sandiganbayan on August 28, 2002  (A.M. No. 02-6-07—SB)


Court of Tax Appeals

Created by Republic Act No. 1125 on June 16, 1954, it serves as an appellate court to review tax cases.  Under Republic Act No. 9282, its jurisdiction has been expanded where it now enjoys the same level as the Court of Appeals.  This law has doubled its membership, from three to six justices.


The Supreme Court acting on the recommendation of the Committee on Revision of the Rules of Court resolved to approve the Revised Rules of the Court of Tax Appeals (A.M. No. 05-11-07-CTA) and amended by a resolution of the Court En Banc on November 22, 2005.



The Court of Tax Appeals has exclusive appellate jurisdiction to review by appeal the following:



It also has jurisdiction over cases involving criminal offenses as herein provided:




Regional Trial Courts

They are called the second level courts and are divided into thirteen (13) judicial regions: National Capital Region (Metro Manila) and the twelve (12) regions of the country,   which are divided into several branches.  The jurisdictions are defined in sec. 19-23 of Batas Pambansa Blg. 129 as amended by Republic Act No. 7671.  The Supreme Court designates certain branches of regional trial courts as special courts to handle exclusively criminal cases, juvenile and domestic relations cases, agrarian cases, urban land reform cases which do not fall under the jurisdiction of quasi-judicial bodies. The Supreme Court issues resolutions designating specific branches of the Regional Trial Courts as special courts for heinous crimes, dangerous drugs cases, commercial courts and intellectual property rights violations. Special rules are likewise promulgated.  A.M. No. 00-8-10-SC is a resolution of the Court En Banc on the Rules of Procedure on Corporate Rehabilitation.  The Interim Rules was promulgated in November 2000 and December 2008 affects special commercial courts.  Some Regional Trial Courts are specifically designated to try and decide cases formerly cognizable by the Securities and Exchange Commission (A.M. No. 00-11-030SC)


 Some branches of the Regional Trial Courts have been designated as family courts (A.M. No. 99-11-07) because the family courts to be established pursuant to Republic Act No. 8369 of the Family Court Law of 1997 have not yet been organized.   Pursuant to Republic Act No. 8369, the Family Court Law of 1997, some branches of the Regional Trial Courts have been designated as family courts (A.M. No. 99-11-07).


The Regional Trial Courts’ jurisdictions are defined as follows:



They shall exercise appellate jurisdiction over MeTCs, MTCCs, MTCs, and MCTCs in their respective territorial jurisdiction.


Metropolitan Trial Courts (MeTC), Municipal Trial Courts in Cities (MTCC), Municipal Trial Courts (MTC) and Municipal Circuit Trial Courts (MCTC)

These are called the first level courts established in each city and municipality.  Their jurisdiction is provided for by section 33, 35 of Batas Pambansa Blg 129.  Their jurisdiction has been expanded by special laws namely Republic Act Nos. 9276, 9252, 9305, 9306, and 9308.


MeTCs, MTCCs, MTCs, and MCTCs shall exercise original jurisdiction in Civil Cases as provided for in section 33 of Batas Pambansa Blg. 129 is as follows:



Section 33 of Batas Pambansa Blg. 129 provides that the Supreme Court may designate MeTCs, MTCCs, MTCs, and MCTCs to hear and determine cadastral or land registration cases where the value does not exceed one hundred thousand pesos (P100,000.00).  Their decision is can be appealed in the same manner as the Regional Trial Courts.


The MeTCs, MTCCs, MTCs, and MCTCs are empowered to hear and decide petitions for a writ of habeas corpus or applications for bail in criminal cases in the province or city in the absence of the Regional Trial Court Judges.


By virtue of A.M. No. 08-8-7-SC, enacted September 9, 2008 and effective October 1-2008, the Metropolitan Trial Courts, Municipal Trial Courts in Cities, Municipal Trial Courts and Municipal Circuit Trial Courts were designated  to try small claims cases for payment of money where the value of the claim does not exceed One Hundred Thousand Pesos (P100,000.00) exclusive of interest and costs.  These courts shall apply the rules of procedure provided in A.M. No. 08-8-7-SC in all actions “which are: (a) purely civil in nature where the claim or relief prayed for by the plaintiff is solely for payment or reimbursement of sum of money, and (b) the civil aspect of criminal actions, either filed before the institution of the criminal action, or reserved upon the filing of the criminal action in court, pursuant to Rule 111 of the Revised Rules Of Criminal Procedure.”


Shari’a Courts

These special courts were created by sec. 137 of Presidential Decree No. 1083 or the Code of Muslim Personal Laws.  The judges should possess all the qualifications of a Regional Trial Court Judge and should also be learned in Islamic law and jurisprudence. Articles 143, 144, and 155 of Presidential Decree No. 1083 provides the jurisdiction of the said courts as follows:


Shari’a District Courts (SDC) as provided for in paragraph (1), Article 143 of Presidential Decree No. 1083, shall have exclusive jurisdiction over the following cases:



The SDC in concurrence with existing civil courts shall have original jurisdiction over the following cases (paragraph (2) of Article 143):



Article 144 of Presidential Decree No. 1083 provides that the SDC within shall have appellate jurisdiction over all cases tried in the Shari’a Circuit Courts (SCC) within their territorial jurisdiction.


Article 155 of Presidential Decree No. 1083 provides that the  SCCs  have exclusive original jurisdiction over:


·       All cases involving disputes to communal properties.


Rules of procedure are provided for in articles 148 and 158. En Banc Resolution of the Supreme Court in 183, provided the special rules of procedure in the Shari’a courts (Ijra-at-Al Mahakim Al Sharia’a).


Shari’a courts and personnel are subject to the administrative supervision of the Supreme Court.  Appointment of judges, qualifications, tenure, and compensation are subject to the provisions of the Muslim Code (Presidential Decree No. 1083.  SDCs and SCCs have the same officials and other personnel as those provided by law for RTCs and MTCs, respectively.


Quasi-Courts or Quasi-Judicial Agencies


Quasi-judicial agencies are administrative agencies, more properly belonging to the Executive Department, but are empowered by the Constitution or statutes to hear and decide certain classes or categories of cases.


Quasi-judicial agencies which are empowered by the Constitution are the Constitutional Commissions: Civil Service Commission, Commission on Elections and the Commission on Audit.


Quasi-judicial agencies empowered by statutes are:  Office of the President. Department of Agrarian Reform, Securities and Exchange Commission, National Labor Relations Commission, National Telecommunication Commission, Employees Compensation Commission, Insurance Commission, Construction Industry Arbitration Commission, Philippine Atomic Energy Commission, Social Security System, Government Service Insurance System, Bureau of Patents, Trademark and Technology, National Conciliation Mediation Board, Land Registration Authority, Civil Aeronautics Board, Central Board of Assessment Appeals, National Electrification Administration, Energy Regulatory Board, Agricultural Inventions Board and the Board of Investments. When needed, the Supreme Court issues rules and regulations for these quasi-judicial agencies in the performance of their judicial functions.  Republic Act No. 8799, known as the “Securities Regulation Code,” reorganized the Securities and Exchange Commission (Chapter II) and provided for its powers and function (sec.5).  Specifically provided for in these powers and function is the Commission’s jurisdiction over all cases previously provided for in sec. 5, Pres. Decree No. 902-A (sec. 5.2).  The Supreme Court promulgated rules of procedure governing intra-corporate controversies under Republic Act No. 8799 (A.M. No. 01-2-04-SC).


Decisions of these quasi-courts can be appealed to the Court of Appeals except those of the Constitutional Commissions: Civil Service Commission, Commission on Elections and the Commission on Audit, which can be appealed by certiorari to the Supreme Court (Art. IX-A, sec. 7).


Other Judicial Procedures


Katarungang Pambarangay - Presidential Decree No. 1508, or the Katarungang Pambarangay Law, took effect December 11, 1978, and established a system of amicably settling disputes at the barangay level.  Rules and procedures were provided by this decree and the Local Government Code, Title I, Chapter 7, sec. 339-422). This system of amicable settlement of dispute aims to promote the speedy administration of justice by easing the congestion of court dockets.  The Court does not take cognizance of cases filed if they are not filed first with the Katarungang Pambarangay.


Alternative Dispute Resolution (ADR) System - Republic Act No. 9285 institutionalized the use of an alternative dispute resolution system which serves to promote the speedy and impartial administration of justice and unclog the court dockets.  This act shall be without prejudice to the adoption of the Supreme Court of any ADR system such as mediation, conciliation, arbitration or any combination thereof.  The Supreme Court by virtue of an En Banc Resolution dated October 16, 2001 (Administrative Matter No. 01-10-5-SC-PHILJA), designated the Philippine Judicial Academy as the component unit of the Supreme Court for court-referred or court-related mediation cases and alternative dispute resolution mechanism and establishing the Philippine Mediation Center.  Muslin law provides its own arbitration Council called The Agama Arbitration Council.


3.4 Constitutional Commissions


Civil Service Commission - Act No. 5  (1900) established the Philippine  civil service and was reorganized as a Bureau in 1905.  It was established in the 1935 Constitution.  Republic Act No. 2260 (1959) converted it from a Bureau into the Civil Service Commission. Presidential Decree No. 807 further redefined its role. Its present status is provided for in the 1987 Constitution, Art. IX-B and reiterated by the provision of the 1987 Administrative Code (Executive Order No. 292).


Commission on Elections - It is the constitutional commission created by a 1940 amendment to the 1935 Constitution whose primary function is to manage to maintain its authority and independence in the conduct of elections.  The COMELEC exercises administrative, quasi-judicial and judicial powers.  Its membership increased to nine with a term of nine years by the 1973 Constitution. It was however decreased to seven with a term of seven years without re-appointment by the 1987 Constitution.


Commission on Audit - Article IX, sec, 2 of the 1987 Constitution provided the powers and authority of the Commission on Audit, which is to examine, audit and settle all accounts pertaining to the revenue and receipts of and expenditures or uses of funds and property owned or held in trust by or pertaining to the Government including government owned and controlled corporations with original charters.


The  Bangko Sentral ng Pilipinas (Central Bank) is considered as a constitutional office in the official Philippine government directory.


3.5 Local Governments


Article X of the 1987 Constitution provides for the territorial and political subdivisions of the Philippines as follows: province, cities, municipalities and barangays. The 1991 Local Government Code or Republic Act No. 7160, as amended by Republic Act No. 9009,   provides the detail that implements the provision of the Constitution.  The officials, namely, the governor, city mayor, city vice mayor, municipal mayor, municipal vice-mayor and punong barangay are elected by their respective units. (1991 Local Government Code, Title II, Chapter 1, sec. 41 (a)).  The regular members of the sangguniang panlalawigan (for the province), sangguniang panglunsod (for cities), sangguniang bayan (municipalities) are elected by districts while the sangguniang barangay are elected at large.


Each territorial or political subdivision enjoys local autonomy as defined in the Constitution. The President exercises supervision over local Governments. 


Each region is composed of several provinces while each province is composed of a cluster of municipalities and component cities (Local Government Code, Title IV, Chapter 1, sec. 459). The   Provincial government is composed of the governor, vice-governor, members of the sangguniang panlalawigan  and other appointed officials


The city  consists of more urbanized and developed barangays which are created, divided, merged, abolished or its boundary altered by  law or act of Congress, subject to the approval of majority votes cast by its residents in a plebiscite conducted by the Comelec (Local Government Code,  Title III, Chapter 1, sec. 448-449).  A City may be classified either as a component or highly urbanized.  The city government is composed of the mayor, vice-mayor, members of the sangguniang panlunsod (which is composed of the president of the city chapter of the liga ng mga barangay, president of the panlungsod ng mga pederasyon ng mga sangguniang kabataan and the sectoral representatives) and other appointed officials. 


The municipality consists of a group of barangays which is created, divided, merged, abolished or its boundary altered by  law or act of Congress, subject to the approval of majority votes casts in a plebiscite conducted by the Comelec (Local Government Code,  Title II, Chapter 1, sec. 440-441).  The municipal government is composed of the mayor, vice-mayor, sangguniang members (which is composed of president of the municipal chapter of the liga ng mga barangay, president of the pambayang  pederasyon ng mga sangguniang kabataan  and the sectoral representatives) and other appointed officials. In order for a municipality to be converted into cities, a law or act of Congress must be passed by virtue of the provisions of the Local Government Code and the Constitution.  A plebiscite must be conducted to determine if a majority of the people in the said municipality are in favor of converting the municipality into a city.  Although laws have been passed, their constitutionality can be question in the Supreme Court.   This can be seen in the November 18, 2008 decision penned by Justice Antonio T. Carpio. The League of Cities of the Philippines, City of Iloilo, City of Calbayog filed consolidated petitions questioning the constitutionality of the Cityhood Laws and enjoined the Commission on Elections and the respondent municipality from conducting plebiscites.  The Cityhood Laws were declared as unconstitutional for they violated sections 6 and 10, Article X of the 1987 Constitution. The Cityhood laws referred to in this case are: Republic Acts 9389, 9390, 9391, 9392, 9293, 9394, 9398, 9404, 9405, 9407, 9408, 9409, 9434, 9435, 9436 and 9491. (League of Cities of the Philippines (CP) represented by LCP National President Jerry Trenas v. Commission on Elections, G.R. No. 176951, 177499, 178056, November 18, 2008)   


The Barangay is the smallest local government unit  which is created, divided, merged, abolished or its boundary altered by  law or by an ordinance of the sangguniang panlalawigan or sangguniang panlunsod, subject to the approval of majority votes casts in a plebiscite conducted by the Comelec (Local Government Code,  Title I, Chapter 1, sec. 384-385)


The Philippines is divided into the following local government units:



The Caraga Administrative Region (Region III) was created by Republic Act No. 7901 which was  passed by both houses of Congress and approved by the President on February 23, 1995.  The Autonomous Region in Muslim Mindanao was created by Republic Act No. 6734 was passed by both houses of Congress on February7, 2001 and lapsed into law without the signature of  the President in accordance with Article VI, Section 27 (1) of the Constitution on  March 31, 2001.  The Cordillera Autonomous Region was created by Republic Act No. 6766 which was approved on October 23, 1989.   


3.6 Other Government Agencies


Commission on Human Rights - The Commission on Human Rights was created as an independent office for cases of violation of the human rights (Art. XIII, sec. 17). Specific powers and duties are expressly provided for by section 18 of the 1987 Constitution.  It is composed of a Chairperson and four (4) members.


Office of the Ombudsman - The 1987 Constitution explicitly provides that Ombudsman and his deputies are called the protectors of the people for they are tasked to act promptly on complaints filed against public officials or employees of the government including government owned and controlled corporations (Art. XI, sec. 12). Its powers, duties and functions are provided for in section 13. It is responsible for prosecuting government official for their alleged crimes. However, Republic Act No. 6770, sec, 15 provides that the Ombudsman shall give priority to complaints filed against high ranking government officials and those occupying supervisory positions.   It is composed of the Ombudsman and six (6) deputies.


The President, Vice President, members of the Supreme Court, Constitutional Commission and the Ombudsman may be removed from office by impeachment for conviction of violations of the Constitution, treason, bribery, graft and corruption, other high crimes or betrayal of public trust. (Art. XI, sec. 2).  The House of Representatives has the exclusive power to initiate (Art. XI, sec. 3 (1)) while the Senate has the sole power to try and decide impeachments cases (Art. XI, sec. 3(6)).  All other public officials and employees may be removed by law (Art. XI, sec. 2 the Civil Service Law).


4. Legal System


4.1 Nature of the Philippine Legal System


The Philippine legal system may be considered as a unique legal system because it is a blend of civil law (Roman), common law (Anglo-American), Muslim (Islamic) law and indigenous law. Like other legal systems, there  are two main sources of law.


4.2 Sources of Law

There are two primary sources of the law:  



Classification of Legal Sources

Primary Authority is the only authority that is binding on the courts.  


Classification by Authority

“Authority is that which may be cited in support of an action, theory or hypothesis.”  Legal of materials primary authority are those that contain actual law or those that contain law created by government.  Each of the three branches of government: Legislative, Executive and Judiciary, promulgates laws.


The legislature promulgates statutes, namely: Act, Commonwealth Act, Republic Act, Batas Pambansa.  Executive promulgates presidential issuances (Presidential Decrees, Executive Orders, Memorandum Circular, Administrative Orders, Proclamations, etc.), rules and regulations through its various departments, bureaus and agencies. The Judiciary promulgates judicial doctrines embodied in decisions.  We however need to clarify that the Presidential Decrees or law issued by President Ferdinand E. Marcos during Martial Law and Executive Orders issued by Aquino President Corazon C.  Aquino before the opening Congress in July 1987 can be classified as legislative acts, there being no legislature during these two periods.


Primary Authority or sources may be further subdivided into the following:


It is in this regard that the collections of law libraries in the Philippines include United States court reports, West’s national reporter system, court reports of England and international tribunal, important reference materials such as the American Jurisprudence, Corpus Juris Secundum, Words and Phrases and different law dictionaries.  Some of these law libraries subscribe to the Westlaw and/or LexisNexis.  The Supreme Court , University of the Philippines, University of Santo Tomas and a number of prominent law libraries also have a Spanish collection where a great number of  our laws originated.


Secondary authority or sources are commentaries or books, treatise, writings, journal articles that explain, discuss or comment on primary authorities. Also included in this category are the opinions of the Department of Justice,  Securities and Exchange Commission or circulars of the Bangko Sentral ng Pilipinas. These materials are not binding on courts but they have persuasive effect and/or  the degree of persuasiveness.  With regards to commentaries or books, treatise, writings, journal articles,  the reputation  or expertise of the author is a consideration.  Some of the authors of good reputation and  considered experts in the field  are Chief Justice Ramon C. Aquino and Justice Carolina Grino Aquino on Revised Penal Code or Criminal Law,  Senator Arturo M. Tolentino on Civil law,  Chief Justice Enrique M. Fernando and Fr. Joaquin Bernas on Constititional Law, Prof. Perfecto Fernandez on Labor Law, Vicente Francisco,  Chief Justice Manuel Moran on Remedial  Law, and Justice Vicente Abad Santos and Senator Jovito Salonga on International Law, etc. 


Classification by Source

It is important for legal research experts to know the source where the materials were taken from.  One has to determine whether they came from primary (official) sources or secondary (unofficial sources).  Primary and secondary sources for the sources of law are found in the Philippine Legal Information Resources and Citations section - part II - of the 2009 Update.


Primary sources are those published by the issuing agency itself or the official repository, the Official GazetteThus, for Republic Acts and other legislative enactments or statutes, the primary sources are the Official Gazette published by the National Printing Office and the Laws and Resolutions published by Congress.  For Supreme Court decisions, the primary sources are the Philippine Reports, the individually mimeographed Advance Supreme Court decisions (discontinued by the Supreme Court effective January 2009) and the   Official Gazette.  Publication of Supreme Court decisions in the Official Gazette is selective.  Complete court reports for Supreme Court decisions from 1901 to the present can be found in the Philippine Reports.


The Secondary Sources are the unofficial sources and generally referred to as those commercially published or those that are not published by government agencies or instrumentalities.


Some of the Secondary sources of statutes are the Vital Legal Documents, published by the Central Book Supply, contains a compilation of Presidential Decrees (1973). The second edition contains  Republic Acts. Prof. Sulpicio Guevara published three books which contain s the full text of legislative enactments  or laws namely:  a).  Public Laws Annotated (7 vols.) ,  compilation of all laws from 1901 to 1935, b). Commonwealth Acts Annotated (3vos.).  compilation of laws from 1935-1945  c).  The Laws of the First Philippine Republic (The Laws of Malolos) 1898-1899.  For the Supreme Court decisions, Supreme Court Reports Annotated (SCRA), a secondary source, published by the Central Book Supply is more  updated and popular in the legal community  than the Philippine Reports, the primary and official source. Citations in commentaries or books, treatise, writings, journal articles, pleading and even court decisions show  SCRA’s  popular acceptance. The general rule is that in the absence of a primary source, the secondary source may be cited.  This was the primary rationale for the SCRA’s popularity.  There was no primary source for complete compilation of Supreme Court decisions for more than twenty (20) years.  The publication of the Philippine Reports by the National Printing Office ceased in 1960s.  It was only in 1982 when the publication of the Philippine Reports was revived by then Chief Justice Enrique M. Fernando who requested then President Ferdinand E. Marcos to take charge of its publication with special appropriation in the Judiciary’s annual budget.


With the advent of the new information technology, electronic or digitized sources are popular sources of legal information for the following reasons:  a) updated legal information is readily available and b) the search engines used facilitate research, and c) no complete and update manually published search tools for statute and case law.  These electronic sources are in the forms of CD ROMS, online or virtual libraries of the issuing government agency or instrumentality and the now growing websites of law offices such as Chan Robles Law Firm Library and Jaromay, Laurente Law Office On Line Library, or law schools such as the Arellano Law Foundation Lawphil. Net. In case of conflict between the printed and electronic sources, the printed version coming from the issuing government agency prevails.  This policy prevails even for the Supreme Court E-Library, where it is explicitly provided in its website.


Legal research for statute law in the Philippines benefited remarkably from the use of the latest technology due to two major problems:  a) no complete and updated published or printed search tools  or law finders  for statute law and b) no complete compilation of statute law from 1901-present were available.  Problems of the publication of compilations of statute law or the existence of the full-text  of Presidential Decrees was even brought to the Supreme Court in the Tanada v. Tuvera, G.R. No.  63915, April 24, 1985 (220 Phil 422), December 29, 1986 (146 SCRA 446)   case. This case which was first decided before the bloodless revolution popularly known as People Power or the EDSA Revolution was modified in the December 29, 1986 or after the People Power or the EDSA Revolution.


Still, with regards to Statute Law in the Philippines, the other problem is how to classify sources published in the newspapers.  Since 1987, based on the definition of primary and secondary source, they may be considered as primary sources pursuant to Executive Order No. 200, s. 1987 which provides that laws become effective fifteen (15) days after publication in the Official Gazette or in two newspapers of general circulation.  In case of conflict between the two versions, the version of the Official Gazette holds. 


In finding the law, our ultimate goal is to locate mandatory primary authorities which have bearing on the legal problem at hand.  If these authorities are scarce or nonexistent, our next alternative is to find any relevant persuasive mandatory authority.  If our search is still negative, the next alternative might be secondary authorities.  There are however instances where the secondary authorities, more particularly the commentaries made by experts of the field, take precedence over the persuasive mandatory authorities.  With the availability of both, using both sources is highly recommended.


Classification by Character

This refers to the nature of the subject treated in books.  This classification categorizes books as : a) Statute Law Books,  b) Case Law Books or Law Reports, c) a combination of both and d) “Law Finders.”


Law Finders refer to indexes, citators, encyclopedias, legal dictionaries, thesauri or digests. A major problem in the Philippines is that there are no up-to-date Law Finders.  Federico Moreno’s Philippine Law Dictionary, the only available Philippine law dictionary was last published in 1988, and, Jose Agaton Sibal’s  Philippine Legal Thesaurus which is likewise considered a dictionary was published in 1986. Foreign law dictionaries like Blacks’  Law Dictionary, Words and Phrases are used as alternate. To search for legal information, legal researchers go online virtual libraries such as the Supreme Court E-Library (, Chan Robles Virtual Law Library, and the different databases in CD-ROM format from CD Asia Technologies Asia Inc.  The databases developed by CD Asia include not only the compilation of Laws (statutes) and Jurisprudence, but also include a compilation of legal  information that are not available in printed form such as Opinions of the Department of Justice, Securities and Exchange Commission and Bangko Sentral (Central Bank) rules and regulations.  Search engines used in these databases answer for the lack of complete and updated indexes of legal information.  In this regard, effective legal research can be conducted with one cardinal rule in mind:  "ALWAYS START FROM THE LATEST." The exception to this is when the research has defined or has provided a SPECIFIC period.


5. Philippine Legal Research


5.1 Research of Statute law

Statute laws are the rules and regulations promulgated by competent authorities; enactments of legislative bodies (national or local) or they may be rules and regulations of administrative (departments or bureau) or judicial agencies. Research of statutory law does not end with consulting the law itself.  At times it extends to the intent of each provision or even the words used in the law. In this regard, the deliberations of these laws must be consulted. The deliberation of laws, except Presidential Decrees and other Martial law issuances, are available.



The different Constitutions of the Philippines  are provided  in some history books such as Gregorio F. Zaide’s Philippine Constitutional History and Constitutions of Modern Nations (1970) and Founders of Freedom; The History of Three Constitution by a seven-man Board.  The Philippine legal system recognizes the following Constitutions:  Malolos, 1935, 1973, Provisional or Freedom and 1987 Constitutions.


Text of the Malolos Constitution is available in some history books such as Gregorio F. Zaide’s Philippine Constitutional History and Constitutions of Modern Nations, p. 176 (1970). For the rest of the above mentioned Constitutions, the texts are available in published Philippine constitutional law books. Full text of these Constitutions will be available at the Supreme Court E-Library.


The Constitutional Convention proceedings provide for the intent and background of each provision of the Constitution.  Sources for the  1934-1935  Constitutional  Convention are: 10 volumes of the Constitutional Convention Record  by the House of Representatives (1966), Salvador Laurel's seven volumes book entitled Proceedings of the Constitutional Convention (1966); 6 volumes of the  Philippine Constitution, Origins, Making, Meaning and Application by the Philippine Lawyers Association with Jose Aruego as one of  its editors (1970) and Journal of  the Constitutional convention of the Philippines by Vicente Francisco.


Proceedings of the 1973 Constitutional Convention were never published.  A photocopy and softcopy of the complete compilation is available at the Filipiniana Reading Room of the National Library of the Philippines.


Journals (3 volumes) and Records (5 volumes) of the Constitutional Convention of 1986 were published by the Constitutional Commission.  This publication does not have an index. This problem was remedied when CD Technologies Asia Inc. came out with a CD-ROM version which facilitated research for it has a search engine.


The proceedings and text of the 1935, 1973 and 1987 Constitutions will be available at the Supreme Court E-Library.


Commentaries or interpretations on the constitution, decisions of the Supreme Court and other courts, textbooks or treaties, periodical articles of the different Constitution are available. (See. Legal Bibliography on page 34)


Treaties and other International Agreements

A treaty is an agreement or a contract between two (bilateral) or more (multilateral) nations or sovereigns, entered into by agents appointed (generally the Secretary of Foreign Affairs or ambassadors) for the purpose and duly sanctioned by supreme powers of the respective countries.  Treaties that do not have legislative sanctions are executive agreements which may or may not have legislative authorization, and which have limited execution by constitutional restrictions


In the Philippines, a treaty or international agreement shall not be valid and effective unless concurred in by at least two-thirds of all members of the Senate (Constitution, Article VII, section 21).  Those without the concurrence of the Senate are considered as Executive Agreements.


The President of the Philippines may enter into international treaties or agreements as the national welfare and interest may require, and may contract and guarantee foreign loans on behalf of the Republic, subject to such limitations as may be provided by law.  During the time of Pres. Marcos, there was the so-called Tripoli Agreement.


The official text of treaties is published in the Official Gazette, Department of Foreign Affairs Treaty Series (DFATS), United Nations Treaty Series (UNTS) or the University of the Philippines Law Center's Philippine Treaty Series (PTS).  To locate the latest treaties, there are two possible sources: Department of Foreign Affairs and the Senate of the Philippines.  There is no complete repository of all treaties entered into by the Philippines. There is a selective publication of treaties in the Official Gazette.  The DFATS was last published in the 1970s while the PTS's last volume, vol. 8 contains treaties entered into until 1981.With the UN Treaty Series, it is available only in UN depository libraries in the country and its United Nation Information Center in Makati. Forthcoming will be the compilation of treaties from 1946-2007 in CD-ROM at the Supreme Court Library.


For tax treaties Eustaquio Ordoño has published a series on the Philippine tax treaties.  Other sources of important treaties are appended in books on the subject or law journals such as the American Journal of International Law or the Philippine Yearbook of International Law.


To locate these treaties, the Foreign Service Institute published the Philippine Treaties Index (1946-1982) and UN Multilateral Treaties Deposited with the Secretary General.   Electronically, major law libraries use the Treaties and International Agreements Researchers Archives (TIARA), WESTLAW,  LEXIS, other online sources and the Internet.


Statutes Proper (Legislative Enactments)

Statutes are enactments of the different legislative bodies since 1900 broken down as follows:



The above figures clearly show that during Martial Law, both President Marcos and the Batasang Pambansa (Parliament) were issuing laws at the same time - Presidential Decrees by President Marcos and Batas Pambansa by the Philippine Parliament.  


During Martial Law, aside from Presidential Decrees,  the President  promulgated other issuances namely: 57 General Orders, 1,525 Letters of Instruction, 2,489 Proclamations, 832 Memorandum Order, 1,297 Memorandum Circular, 157 Letter of Implementation, Letter of Authority, Letters of Instruction, 504 Administrative Order and  1,093 Executive Orders. 


As previously stated, the Presidential Decrees issued by Pres. Marcos during Martial Law and the Executive Orders issued by Pres. Aquino before  the opening of  Congress may be classified as legislative acts for there was no legislature during those two periods.


Laws passed by the new 1987 Congress started from Rep. Act No. 6636, as the last Republic Act promulgated by Congress before Martial Law was Rep. Act No. 6635.


The following are the Philippine codes adopted from 1901 to present:


From the above list of codes, recently amended is the Fire Code of the Philippines, Republic Act No. 9514 - "An Act Establishing a Comprehensive Fire Code of the Philippines Repealing Presidential Decree No. 1185 and for Other Purposes", Approved by the President on December 19, 2008.


The House of Representatives prepared the procedure on how a bill becomes a law.  This procedure is pursuant to the Constitution and recognized by both Houses of Congress.  To better appreciate the procedure, a diagram was prepared by the House of Representatives.

Administrative acts, orders and regulations of the President touching on the organization or mode of operation of the government, re-arranging or adjusting districts, divisions or parts of the Philippines, and acts and commands governing the general performance of duties of public officials and employees or disposing of issues of general concern are made effective by Executive Orders.  Those orders fixing the dates when specific laws, resolutions or orders cease to take effect and any information concerning matters of public moment determined by law, resolution or executive orders, take the form of executive Proclamation.


Executive Orders and Proclamations of the Governor-General were published annually in a set Executive Orders and Proclamations.  Thirty three (33) volumes were published until 1935 by the Bureau of Printing.  Administrative Acts and Orders of the President and Proclamations were published. Only a few libraries in the Philippines have these publications for the majority were destroyed during World War II.  There are copies available at the Law Library of Congress, Cincinnati Law Library Association (who offered to donate them to the Supreme Court of the Philippines) and some at the Library of the Institute of South East Asian Studies in Singapore.


In researching for Proclamations, Administrative Orders, Executive Orders and Memorandum Orders & Circulars of the President, the year it was promulgated is a must, or if no year is available, the President issuing it must be stated. As a new President is sworn in, all the Presidential issuances start with No. 1.  The only exception was Executive Orders issued by President Carlos Garcia after he assumed the Presidency because President Magsaysay died in a plane crash.  He continued the number started by President Magsaysay. When President Garcia was elected  President, he started his Executive Order No. 1.


To look for the intent of Republic Acts, we have to go through the printed Journals and Records of both houses of Congress which contain their  deliberation. To facilitate the search,  the House Bill No. or Senate Bill No. or both found on the upper left portion of the first page of the law  is important. The proceedings of the House of Representatives  and the Philippine Senate  are now available on their websites. The Batasang Pambansa has likewise published it proceedings.  There are no available proceedings for the other laws Acts, Commonwealth Act and Presidential Decrees.



Administrative Rules and Regulations

Administrative Rules and regulations are orders, rules and regulations issued by the heads of Departments, Bureau and other agencies of the government for the effective enforcement of laws within their jurisdiction.  However, in order that such rules and regulations may be valid, they must be within the authorized limits and jurisdiction of the office issuing them and in accordance with the provisions of the law authorizing their issuance.   Access to administrative rules and regulations have been facilitated due to the two developments:  a) government agencies, including government owned and controlled corporations, have their own websites where they include the full-text of their issuances, and b) the National Administrative Register, which is available in print, CD-Rom and in the Supreme Court website.


In handling these types of materials, there are two important items needed: a.) Issuing Agency and b.) Year it was promulgated.  This is due to the fact that all Departments, Bureaus, and other government agencies use the administrative orders, memorandum orders and memorandum circulars for their administrative rules and regulations and they start always with number 1 every year. Even the Supreme Court issues Administrative Orders, Circulars, Memorandum Orders, and Administrative Matters.


Before the Administrative Code of 1987, these orders, rules and regulations were selectively published in the Official Gazette.  Thus, the only source to be able to get a copy of the text of these rules and regulations is the issuing government agency itself. 


When the 1987 Administrative Code (Executive Order No. 292) was promulgated, all governmental and department orders, rules and regulations have to be filed with the University of government agencies including government owned and controlled corporations have to file three (3) certified  copies of their orders, rules and regulations  with the University of the Philippines Law Center's Office of National Administrative Register and  are required to publish quarterly in a publication called National Administrative Register. Aside from the printed copies, the National Administrative Register is available electronically on CD-ROM (CD Asia Technologies Inc.)  and online at the Supreme Court E-Library.  Rules in force on the date on which the Code took effect which are not filed within three months from the date not thereafter shall be the basis of any sanction against any person or party.  Each rule becomes effective 15 days after the filing, unless a different date is fixed by law or specified in the rule, such as in cases of imminent danger to public health, safety and welfare, the existence of which must be expressed in a statement accompanying the rule.  The court shall take judicial notice of the certified copy of each rule duly filed or as published in the bulletin or codified rules


University of the Philippines Law Center’s Office of National Administrative  Register is not only tasked to publish this quarterly register but must keep an up-to-date codification of all rules thus published and remaining in effect together with a complete index and appropriate tables.  Every rule establishing an offense or defining an act which pursuant to law is punishable as a crime or subject to a penalty shall in all cases be published in full text.  Exceptions to the “filing requirement" are Congress, Judiciary, Constitutional Commission, military establishments in all matters relative to Armed Forces personnel, the Board of Pardons and Parole and state universities and colleges.


As previously stated, there are no up-to-date or complete Statutes finders.  Those published are listed in the Philippine Legal Information  Resources and Citations  (part  II of the 2009 Update ). As previously stated, to facilitate legal research, one has to go online to virtual libraries such as the Supreme Court E-Library, Chan Robles Virtual  Law Library, Arellano Law Foundation’s The I Lawphil Project, and CD Asia Technologies or the different databases in CD ROM  such as  those of  CD Asia Technologies Asia Inc., !e-library!

5.2 Research of Case Law


SOURCE: 2002 Revised Manual of Clerks of Court. Manila, Supreme Court, 2002. Organizational Chart was amended due to the passage of  Republic Act No. 9282 (CTA)


Case Law or Judicial decisions are official interpretations or manifestation of law made by persons and agencies of the government performing judicial and quasi-judicial functions.  At the apex of the Philippine Judicial System is the Supreme Court, or what is referred to as court of last resort.  The reorganization of the Judiciary of 1980 (Batas Pambansa Bldg. 129) established the following courts:


The Shariah (Sharia’a) Circuit and District Courts (Presidential Decree No. 1083),  Court of Tax Appeals (Republic Act No. 1125) and the Sandiganbayan (Presidential Decree Nos.  1486 and 1606), sec. 4, Art XI of the 1987 Constitution were created by separate laws.


Conventional decisions are decisions or rulings made by regularly constituted court of justice.  Subordinate decisions are those made by administrative agencies performing quasi-judicial functions.


One major problem in conducting research on case law is the availability of published or printed decisions from the Court of Appeals to the rest of the judicial and quasi-judicial agencies.   The Judicial Reform Program of the Supreme Court with the establishment of the Supreme Court E-Library aims to  address this problem and also those from statute law. The decisions of the Supreme Court, Court of Appeals, Sandiganban and the Court of Tax Appeals will be made available in the Supreme Court E-Library.  Downloading of the decisions of the Appellate Courts have started from the most recent and will continue until all their first decision from their creation  will be completed. The Reporters Office of the Supreme Court and the Court of Appeals keep all the original and complete copies of the court decisions.  For the rest of the members of the Judiciary or the quasi-judicial agencies, copies of their decisions may be taken from the Legal Office, Office of the Clerks of Court or their libraries.


Supreme Court Decisions

Decisions of the Supreme Court bind the lower courts and are a source of law, the law of the land.  It is the judgment of this court which determines whether a law is constitutional or not.  Unconstitutional laws even though it is signed by the President and passed by both house of congress can not take effect in the Philippines.


Decisions of the Supreme Court are classified as follows:




Case Reports in the Philippines such as the Philippine Reports, Supreme Court Reports Annotated (SCRA), and the Supreme Court Advance Decisions (SCAD) come in bound volumes which generally cover a month per volume.  The Official Gazette and Philippine Reports are the official repositories of decisions and extended resolutions of the Supreme Court.  The difference between the two lies in the fact that the Official Gazette selectively publishes Supreme Court decisions while Philippine Reports contains all decisions of the Supreme Court except minute resolutions.  However, from 1901 until 1960, there were unpublished decisions of the Supreme Court.  The list and subject field are found at the back of each volume of the Philippine Reports.   Some of these decisions are cited in treatises or annotations.  In view to the importance of these decisions, the late Judge Nitafan of the Regional Trial Court of Manila started publishing   Supreme Court Unpublished Decisions; vol. 1 covers decisions from March 1946 to February 1952.  


Even before the war, there were unpublished decisions of the Court.   The source of these unpublished decisions is the Office of the Reporter of the Supreme Court.  Due to World War II, a number of the original decisions have been burned. So, there is no complete compilation of the original decisions of the Supreme Court.  This problem is being addressed  by the Supreme Court E-Library where are great number of these unpublished decisions of the Supreme Court before the war were retrieved from different sources such as the  United States National Archives in Maryland, private collection of former  Supreme Court Justices such as Chief Justice Ramon Avancena and Justice George Malcom (collection is found in the University of Michigan) and private law libraries who were able to save some of their collection such as the University of Santo Tomas, the oldest university in the Philippines. Search for the unpublished decisions still continues.  A list of these unpublished decisions is in the Supreme Court E-Library, Project COMPUSDEC, under JURISPRUDENCE.


The early volumes, particularly those before the war were originally published in Spanish in the Jurisprudencia Filipina. They were translated in English to become the Philippine Reports.  Some decisions after the second Philippine independence were still in the Spanish language.  There are a number of decisions now in the Filipino language. The Philippine Reports until volume 126 (1960's) was published by the Bureau of Printing, now called the National Printing Office. Printing was transferred to the Supreme Court in the 1980s due to the need for a complete official publication of the Court’s decision. The Supreme Court’s Philippine Reports started with volume 127.


The most popular secondary source is the Supreme Court Reports Annotated (SCRA).  Actually, legal practitioners cite it more than the Philippine Reports and the Lex Libris Jurisprudence CD ROM.

Court of Appeals decisions

Decisions of the Court of Appeals are merely persuasive on lower courts.  They are cited in cases where there are no Supreme Court decisions in point.   In this regard, they are considered as judicial guides to lower courts and that conclusion or pronouncement they make can be raised as a doctrine.


Sources of Court of Appeals decisions are:




Decisions of Special Courts

Sandiganbayan and the Court of Tax Appeals do not have published decisions.  The Sandiganbayan has only one volume published; Sandiganbayan Reports vol. 1 covers decisions promulgated from December 1979 to 1980. 


Court of Tax Appeals decisions from 1980 to 2004 are found in the Lex Libris particularly in Taxation CD ROM.


Decisions of Administrative Agencies, Commissions and Boards

Laws have been promulgated which grants some administrative agencies to perform quasi-judicial functions. These functions are distinct from their regular administrative or regulatory functions where rules and regulations are promulgated. The Securities Regulations Code (Republic Act No. 8799) signed by President Joseph E.  Estrada  on July 19,2000  affects Securities and Exchange Commission's (SEC) quasi-judicial functions. The other agencies performing said functions are National Labor Relations Commission (NLRC), Insurance Commission, Housing and Land Use Regulatory Board (HLURB), Government Service Insurance System (GSIS), Social Security System (SSS) and even the Civil Service Commission (CSC).  Some of their decisions are published in the Official Gazette.  Some have their own publication such as the SEC and the CSC or some include them in their own websites


CD Asia Technologies’ Lex Libris series has individual CD ROMs  for the Department of Justice, Securities and Exchange Commission, Bangko Sentral ng Pilipinas (Central Bank of the Philippines), and the Bureau of Internal Revenue.  Included in these individual CD ROMs are the pertinent laws, their respective issuances as well as Supreme Court decisions.   It CD ROM on Labor (vol. VII) incorporated issuances from the Department of Labor and Employment and its affiliated agencies and offices.  The Trade, Commerce and Industry CD ROM includes  Supreme Court decisions, laws and issuances of its various agencies such as the Department of Trade and Industry, Board of Investments, Bureau of  Customs, Bangko Sentral and the Philippine Stock Exchange.


6. Legal Profession and Legal Education

The Constitution (sec.5) vests the Supreme Court with the power of admission to the practice of law.  The judicial function to admit to the legal profession is exercised by the Supreme Court through a Bar Examination Committee.  The requirements to be able to apply for admission to the bar are provided in Rule 138, sec. 2 and sections 5-6 (academic requirements).  Every applicant for the admission must be a Filipino citizen and at least 21 years of age.  As to the academic requirements, he should have finished a four year pre-law course and a four year law degree.  The Bar Examinations are given during the four (4) Sundays of September of each year.  The lists of lawyers who are allowed to practice are found in the Rolls of Attorneys of the Supreme Court and the publication of the Court entitled, Law List. The online version of the Law List, available in the Supreme Court and Supreme E-Library, includes the annual lists of additional members of the bar.


Special Bar Exams for Shari’a Court lawyers is provided for by virtue of the Court En Banc Resolution dated September 20, 1983. The exam is given every two years.  Although the exam is conducted by the Supreme Court Bar Office, it is the Office of Muslim Affairs who certifies as to who are qualified to take the exam.


Republic Act No. 7662, approved on December 23, 1993, provided for reforms in legal education and created a Legal Education Board.  The Board shall be composed of a Chairman who shall preferably be a former justice of the Supreme Court of Court of Appeals and regular members composed of:  a representative of each of the following: Integrated Bar of the Philippines (IBP), Philippine Association of Law Schools (PALS), Philippine Association of Law Professors (PALP), ranks of active law practitioners and law students’ sector. The reforms in the legal education system envisioned by Republic Act No. 7662 will require proper selection of law students, maintain the quality of law schools and require legal apprenticeship and continuing legal education.


All attorneys whose names are in the Rolls of Attorneys of the Supreme Court who have qualified for and have passed the bar examinations conducted annually, taken the attorney’s oath, unless otherwise disbarred must be a member of the Integrated Bar of the Philippines.   Bar Matter No. 850 was promulgated by the Resolution of the Supreme Court En Banc on August 22, 2000, as amended on October 2, 2001, providing for the rules on Mandatory Continuing Legal Education (MCLE) for Active Members of the Integrated Bar of the Philippines (IBP). The members of the IBP have to complete every three (3) years at least thirty six (36) hours of continuing legal activities approved by the MCLE Committee.  An IBP member who fails to comply with the said requirement shall pay a non-compliance fee and shall be listed as a delinquent member of the IBP.  A Mandatory Continuing Legal Education Office was established by the Supreme Court (SC Administrative Order No. 113-2003) to implement said MCLE. Under the Resolution of the Court en Banc dated September 2, 2008 (Bar Matter No. 1922), the counsel’s MCLE Certificate of Compliance must be indicated in all pleadings filed with the Courts.


6.1 Law Schools


The Office of the Bar Confidant of the Supreme Court  as of January 2009 has the following one hundred five (106)   law schools throughout the Philippines:


The above list from the Office of the Bar Confidant does not include newly organized law schools and/or law schools who do not yet have any graduate to qualify for the annual bar examination.


The following educational Association and/or Organizations:


6.2 Bar Associations


Integrated Bar of the Philippines

The official organization for the legal profession is the Integrated Bar of the Philippines (IBP), established by virtue of Republic Act No. 6397.  This confirmed the power of the Supreme Court to adopt rules for the integration of the Philippine Bar.  Presidential Decree 181 (1973) constituted the IBP into a corporate body.


There are now about 40,000 attorneys who composed the IBP.  These are the attorneys whose names are in the Rolls of Attorneys of the Supreme Court who have qualified for and have passed the bar examinations conducted annually, taken the attorney’s oath, unless otherwise disbarred.  Membership in the IBP is compulsory.  The Supreme Court in its resolution Court En Banc dated November 12, 2002 (Bar Matter No. 1132) and amended by resolution Court En Banc dated April 1, 2003 (Bar Matter No. 112-2002) require all lawyers to indicate their Roll of Attorneys Number in all papers and pleadings filed in judicial and quasi-judicial bodies in additional to the previously required current Professional Tax Receipt (PTR) and IBP Official Receipt or Life Member Number.


Other Bar Associations


Philippine Bar Association is the oldest voluntary  national organization of lawyers in the Philippines which traces its roots to the Colegio de Abogados de Filipinas organized on April 8, 1891. It was formally incorporated as a direct successor of the Colegio de Abogados de Filipinas on March 27, 1958.


The other voluntary bar associations are the Philippine Lawyers Association, Trial Lawyers Association of the Philippines, Vanguard of the Philippine Constitution, PHILCONSA,  All Asia Association, Catholic Lawyers Guild of the Philippines, Society of International Law, WILOCI, Women Lawyers Association of the Philippines (WLAP), FIDA.  The Philippines is also a member of international law associations such as the ASEAN Law Association, and LAWASIA.
