Bar of Northern Ireland

The Bar of Northern Ireland is the professional association of barristers for Northern Ireland, with over 600 members. It is based in the Bar Library, beside the Royal Courts of Justice in Belfast, together with the Bar Council of Northern Ireland (the professional body of the members of the Northern Irish Bar) and the Executive Council. The Executive Council has taken on many of the functions formerly exercised by the Benchers of the Inn of Court of Northern Ireland, which was established at a meeting of the Bench and Bar held on 11 January 1926.

Before the partition of Ireland, barristers throughout the island of Ireland were trained at the King's Inns and were members of the Bar of Ireland. The Government of Ireland Act 1920 split Ireland into two legal jurisdictions, and after 1922, Northern Ireland became a separate legal system. The King's Inns initially hoped partition would not end its all-island remit, and it set up a "Committee of Fifteen" Northern Ireland benchers in 1922. However, this committee sought more independence, and from 11 January 1926, the Inn of Court of Northern Ireland and the Bar Council of Northern Ireland were created.

The Bar of Northern Ireland collaborates with the Bar of Ireland on various initiatives, including the Irish Rule of Law International. The two associations jointly hosted the World Bar Conference in 2024.

Practising members of the Bar of Northern Ireland are eligible to join the Bar of Ireland without taking any further exams. Practising members of the Bar of Ireland have a reciprocal eligibility.

The profession of barrister has been in existence in Ireland since the arrival of the common law system in the 12th century, and co-existed with the profession of aigne until the abolition of the native Brehon law system in approximately the 17th century.

In 1541, the Honorable Society of King’s Inns was established on what is now the site of the Four Courts. This meant that Irish barristers could now train within Ireland, albeit with an obligation to keep terms in one of the Inns of Court in London. This requirement was costly to Irish barristers and was a contentious issue until it was abolished by the Barristers’ Admission (Ireland) Act, 1885.

The regulation of barristers in Ireland increased during the 18th century. The Benchers of the Honorable Society of King’s Inns was the profession's de facto governing body. Originally, the Benchers consisted of the Lord Chancellor, the judges of the superior courts, some senior officers of the superior courts and all the senior members of the Bar, including the Attorney-General, the Solicitor General and the three Serjeants. The Benchers had the power to censure or disbar barristers.

At a meeting of the Irish Bar in February 1816, the Law Library Society was established for the purposes of providing a subscription-based lending library of legal texts to practising barristers. This led to the development of the Law Library as a distinctive feature of the Irish Bar whereby members of the Bar practised not from chambers but from a common library to which they subscribed.
