1. Development of the Irish Legal System

Brehon Law was one of the earliest forms of law in Ireland and there have recently been attempts by the Brehon Law Project to revive interest in the subject. From the late twelfth century, Ireland was increasingly governed by English common law and by 1800 Ireland was fully integrated into the United Kingdom by the Act of Union passed in that year. A new Constitution in 1922 meant that twenty-six counties became the independent ‘Irish Free State.’ Six other counties in Northern Ireland remained part of the United Kingdom, and this has, of course, been the subject of great controversy since then. (See Sarah Carter and Hester Swift’s Guide to the UK Legal System for information on Northern Irish law.).

Article 73 of the 1922 Constitution carried all previous UK law forward into Irish law, which explains why some pre-1922 UK statutes are still in force in Ireland. A similar provision is found in Article 50 of the 1937 Constitution.

2. The Irish Constitution of 1937

The full text of the Constitution of 1937 is available at various sites, for example, at the Office of the Attorney General. This Constitution, which remains in force today, renamed the State Ireland (Article 4) and established four main institutions – the President, the Oireachtas (Parliament), the Government and the Courts.

The President is the directly elected Head of State but his/her powers are largely ceremonial. The President normally acts on the advice (instructions) of the Government. The Oireachtas (Parliament) consists of two Houses – the directly elected Dáil and indirectly elected Seanad. The Government is the executive and consists of the Taoiseach (Prime Minister) and ministers. The most significant courts are the High Court, the Court of Appeal and the Supreme Court. Descriptions of the powers of each of the institutions are available at the following sites:

The Constitution also contains a strong set of fundamental rights in articles 40-44, e.g. rights to equality before the law, freedom of expression, freedom of religion, education, etc. The courts may issue binding decisions that legislation is unconstitutional if it breaches these fundamental rights.

The Constitution has been amended on numerous occasions, and each amendment requires a referendum. In 1972, the Constitution was amended to recognise Ireland’s membership of the EEC (now the EU) and there have been similar amendments to recognise major new European Treaties such as the Amsterdam Treaty of 1997. The Belfast Agreement led to major amendments in 1998. Divorce was introduced by constitutional amendment in 1995, and abortion has been the subject of controversial amendments in 1983, 1992 and 2018.

Ireland is also a member of the Council of Europe and has ratified the European Convention on Human Rights (ECHR). The provisions of the ECHR may be relied upon in domestic courts as a result of the European Convention on Human Rights Act 2003.

3. Primary Legislation: Acts of the Oireachtas

Approximately forty Acts of the Oireachtas are passed each year. These are available in print from the Government Publications Office – see contact details on the Irish Legal Publishers page.

In electronic form, there are various sources:

  • The British and Irish Legal Information Institute (BaiLII) offers Acts as enacted from 1922 to date. Amendments are not incorporated into legislation, so great care must be taken in using this site to search for subsequent amendments of the Acts. Some pre-1922 legislation which continues to apply in Ireland may be found at Irish Statute Book.
  • The Irish Legal Information Initiative (IrLII), originally managed by Professor John Mee of University College Cork Law School, complements UCC’s contribution to the BaiLII project by providing recent Irish material.
  • The Irish Statute Book site provides access to the Acts from 1922 to date and crucially also the Legislation Directory, which lists amendments to date. It is also possible to a certain extent to see whether a particular section of an Act is actually in force by checking the Commencement Orders section of the Legislation Directory.
  • The Law Reform Commission site provides over 350 revised Acts, which are administrative consolidations of Acts. It concentrates on frequently used legislation and is a very valuable resource for checking amendments to legislation.
  • The Houses of the Oireachtas offers access to all Acts passed from 1922 to date, as well as all bills published from 1997 to date. The site lists legislative history of Bills to date, including links to all relevant Parliamentary debates.

4. Secondary Legislation: Statutory Instruments

Most subordinate legislation is made by Government Ministers under powers conferred on them by Acts. Approximately 500 pieces of subordinate legislation are passed per year. Electronic access is provided at the following sites:

  • The British and Irish Legal Information Institute (BaiLII) contains subordinate legislation passed from 1922 to date. There is no list of amendments.
  • The Attorney General’s Office offers Subordinate Legislation from 1922 to date. The site now contains lists of amendments to subordinate legislation from 1999 onwards – choose Legislation Directory à Secondary Legislation. Some assistance regarding older SIs is provided in print form by Richard F. Humphreys’ Index to Irish Statutory Instruments (3 volumes, 1988).

5. Courts and Case Law

The main court’s website contains a particularly useful FAQ section (under ‘About Us’).

The principal printed series of reports are the Irish Reports and Irish Law Reports Monthly, cited as ‘IR’ and ‘ILRM’ respectively. Many cases remain unreported and are kept in the libraries of the main universities or professional bodies. For electronic access to reported and unreported cases, see the following:

  • British and Irish Legal Information Institute (BaiLII). The most significant data here are in the Supreme Court (‘IESC’), Court of Appeal (‘IECA’) and High Court (‘IEHC’) directories. The database is not comprehensive so it is important to consult other sources. BaiLII also provides access to decisions of the Competition Authority (‘IECA’) and Information Commissioner (‘IEIC’). In addition, BaiLII also introduced vendor-neutral citations for the first time in Irish case-law, e.g. a Supreme Court case on BaiLII may be cited as [2000] IESC 12.
  • Courts Service Judgments Database offers access to recent cases from the High Court, Supreme Court and Court of Appeal.
  • Justis is a fee-paying service, which offers access to judgments on an ongoing basis. A seven-day trial is available.
  • LexisNexis. The ‘Ireland’ library contains a large number of reported and unreported cases.
  • Westlaw.IE covers Irish Law Reports Monthly, Employment Law Reports, Irish Current Law Statutes Annotated, and various other materials.
  • European case law is available in various formats. See e.g. the European links.

6. Government Websites

The main Irish government website contains information from every government department and most state bodies. The parts of most legal relevance, which have not been mentioned above, include:

Note also the Citizens’ Information portal site, which includes summaries of relevant laws.

7. Solicitors and Barristers

Solicitors are educated and regulated by the Law Society. Many solicitors’ firms have websites, which are listed at University College Cork.

Barristers are educated by the King’s Inns and regulated by the Bar Council/Law Library. Only a few barristers have websites – see for example Kieron Wood’s.

8. University Law Departments and Schools

The main University Law Departments and Faculties have websites listing staff interests, courses available, etc. Here they are in alphabetical order:

9. Irish Law Websites

The major portal site, managed by the author, is the Irish Law Site hosted by University College Cork Law School. This site has been in existence since 1994 and contains links to all the major resources concerning Irish law, many of which have been mentioned above. It also includes a link to the searchable archive of Irish Law discussion-list messages and the facility to join a low-traffic ‘Updates’ list by filling in one’s name and e-mail address on the home page.

The site includes a list of subject pages on areas such as Commercial Law, Family Law, Property Law and Tort.

Other important Irish law websites include the following:

10. Discussion Lists and Electronic Newsletters

  • Irish Law List has been in existence since 1994 and has an extensive archive of previous messages, which may be searched online. Messages have been moderated since 1997.
  • Irish Law Updates

11. Blogs

See also the list of blogs and twitter feeds.

12. Books

It is difficult to select the most important books on Irish law, and those with a specific interest in a particular area would be well advised to search the online catalogues of major Irish universities (e.g. Trinity College Dublin’s catalogue) for comprehensive listings. What follows is a list of some of the more significant titles in recent years. See also the subject law pages on the Irish law site, e.g. Commercial Law, Criminal Law, etc.
