Ireland is a unitary state covering twenty-six of the thirty-two counties that make up the island of Ireland; the remaining six counties form Northern Ireland, which is part of the United Kingdom.   Ireland gained independence from the United Kingdom in 1922, at which time existing UK law was brought into Irish law. The constitutional name of the state from 1922 to 1937 was the Irish Free State (Saorstát Eireann). In 1937 the Irish Free State was abolished and the present Constitution came into effect: since then the name of the state has been Eire, or in the English language, Ireland.

Under the Constitution, the national parliament is called the Oireachtas (Assembly). It comprises the President and two chambers, the House of Representatives (Dáil Eireann) and the Senate (Seanad Eireann).

From 1922 to 1937, Irish (Gaelic) and English had equal status as official languages, but since 1937 Irish has been the first official language and English the second. In practice most official publications are in English, or bilingual.

Ireland joined the European Union in 1973 and adopted the Euro in 2002.


The Constitution of Ireland, or Bunreacht na hEireann, dates from 1937. Amendments are made by bills passed by the Oireachtas (Parliament), which become acts only if confirmed by referendum.The result of the referendum is published in the Iris Oifigiúil (official gazette).

The Constitution is available in English and Irish on the website of the Department of the Taoiseach (Prime Minister). 

Consolidated amended editions of the Constitution are published periodically by Government Publications under the title Constitution of Ireland; IALS has the 2003 and 1951 editions. The Constitution is also reproduced in Kelly, The Irish Constitution (various editions held at IALS).

Legislation: primary

Printed sources
Statutes are published by the Irish official publisher, Government Publications, under the title Acts of the Oireachtas. IALS Library has the bound Acts of the Oireachtas from 1922 onwards, with indexes, plus individual unbound acts.

There is also an annotated set of acts, Irish Current Law Statutes Annotated (Dublin: Round Hall Press, 1984 - ). It contains statutes as enacted, along with commentary and legislative history and a citator listing amendments. IALS Library has it from 1984 to 1997, and from 2005 to 2011.

For the period 1801 to 1921, see:

Statutes of the United Kingdom of Great Britain and Ireland (1801 to 1868/69)

Public General Statutes (1866-1925)

Before 1800, see:

The Irish statutes: 3 Edward II to the Union, AD 1310-1800 (Dublin, Round Hall Press, 1995)

Statutes and ordinances, and acts of the Parliament of Ireland: King John to Henry V [1199-1413], Henry Berry (ed.) (Dublin, His Majesty's Stationery Office, 1907)

Online sources
Irish primary legislation is freely available on the Irish Statute Book (eISB) website, 1922 onwards. The site is provided by The Office of the Attorney General, Ireland. It provides each act as passed, with commencement dates and lists of amendments. It also includes most of the pre 1922 public and general statutes still in force in the State following the enactment of the Statute Law Revision Act 2007.

Consolidated versions of selected Irish statutes are available on the website of the Irish Law Reform Commission.

The BAILII (British and Irish Legal Information Institute) website also has Irish statutes as passed from 1922 onwards.

The UK Statutes collection on the JustisOne database includes pre-1922 acts which applied to Ireland.

Legislation: secondary

Printed sources
Irish secondary legislation is published in the form of statutory instruments, or, (before 1948) statutory rules and orders. IALS Library's holdings go back to 1934:

Statutory instruments (1948 -  )

Statutory rules and orders (1934 -1947)

Statutory rules and orders prior  to 1948 were not published in bound volumes, so loose issues had to be collected by libraries and specially bound. IALS was fortunate to obtain some of these volumes (1934-1947) as a donation from the Foreign and Commonwealth Office Library and they are kept at classmark RES GA7.E.4.

An official Index to the Statutory Instruments (formerly Index to the Statutory Rules, Orders and Regulations) is published irregularly by the Stationery Office Dublin / Government Publications. It does not cumulate. IALS has it from 1922 onwards.

IALS also has Humphreys' Index to Irish Statutory Instruments (Dublin, Butterworth (Ireland),1988), covering the period 1922-1986 inclusive. The contents are: Volume 1: Statutory Instruments; Volume 2: Enabling Acts; and Volume 3: Subject Index.

Lists of statutory instruments are found in Irish Current Law Statutes Annotated (see primary legislation, above).

Online sources   
Secondary legislation is available on the Irish Statute Book website, 1922 onwards, with details of amendments made from 1999 onwards. It also includes most of the pre 1922 public and general statutes statutes still in force following the enactment of the Statute Law Revision Act 2007.

Specialist reports

There are several series of subject-based law reports in the library:

Judgments of the Court of Criminal Appeal, edited by G.L.Frewen. 1924-1983 in 2 volumes. Dublin, Incorporated Council of Law Reporting for Ireland. Contains formerly unreported judgments.

Pre-twentieth century reports: IALS has a full set of Irish nominate reports on microfilm (classmarks starting "FM9"), as well as some printed volumes.

Tribunals of inquiry: some matters of public concern in Ireland are investigated by tribunals of inquiry set up by the Oireachtas and vested with the powers and privileges of the High Court. The tribunal usually prepares interim reports and a final report with recommendations. Several recent prominent tribunals are listed on the Irish Government's public information website; there are links to websites for some tribunals which are still active.

Online sources of law reports

Lexis®Library has a collection of Irish case law, including the Irish Reports since 1919;  and unreported cases ("Irish Approved Judgments") since 1967. 

Many decisions of Irish courts are available free on the web:-

BAILII (The British and Irish Legal Information Institute):  Supreme Court cases 1998 onwards, with some older landmark decisions; High Court 1997 onwards, plus a few earlier decisions; Court of Criminal Appeal 2004 onwards; Court of Appeal 2014 onwards, plus a few earlier decisions. Also available on BAILII are decisions of the Irish Competition Authority, the Irish Information Commissioner and the Irish Data Protection Commission.

Courts Service Ireland: Supreme Court 2001 onwards; High Court 2004 onwards; Court of Criminal Appeal 2004 onwards; Court of Appeal 2014 onwards, selected District, Circuit and Central Criminal Court cases, plus background information on the history and organisation of the Irish courts.

IRLII, the Irish Legal Infomation Initiative, provides a complete searchable index to judgments of the Irish High Court, Supreme Court and Court of Criminal Appeal from 1997 onwards. It also has the  full text of selected leading cases (arranged by subject), mainly from the 1970s onwards.


IALS Library has The Law reports... Digest of cases decided by the superior and other courts in Ireland.... The actual titles of the volumes vary somewhat, but the work is generally known as the 'Irish Digest' (see classmark GA5.H.2). It is published by the Incorporated Council of Law Reporting for Ireland. The first volume covers cases from 1867 to 1877 and the most recent covers 1994 to 1999.

The Incorporated Council of Law Reporting began an annual Index to Supreme Court and High Court Written Judgments (known as the `Pink Sheets') in 1976. They were intended to be an interim service because of the late publication of law reports and are available in the library up to 1996. The library also holds the Irish Current Law Monthly Digest from 2005 - 2011.

Another publication which could be described as a digest, and to which the library subscribes, is the Annual Review of Irish Law,1987 onwards (published by Round Hall).


The library has a good collection of books on Irish law. Recent titles include:

Black,L and Dunne, P. Law and gender in modern Ireland: critique and reform. Hart, 2019.

Bracken, L. Child law in Ireland. Clarus Press, 2018.

Harrison, A, The Special Criminal Court: practice and procedure. Bloomsbury, 2019.

Hogan, G. Kelly: The Irish Constitution. Bloomsbury, 2018.

MacMaoláin, C. Irish food law: European, domestic and international frameworks. Hart, 2019.

Richardson, E. A guide to mooting in Ireland. Clarus Press, 2019.

The jurisdictional classmarks for Ireland are GA5 and GA7, but some Irish books are found at classmarks for particular subjects, at classmarks beginning with S. It therefore better to look for books on the Catalogue than to browse the shelves, as not everything about Irish law will be shelved in the same place.

Periodicals and indexes

The library holds the well-established Irish law journals and a few other series. Current serial subscriptions include:

Dublin University Law Journal, 1976-

Gazette (Law Society of Ireland), 1969/70-

Hibernian Law Journal, 2000-

Irish Criminal Law Journal, 1991-
