Northern Ireland law
Northern Ireland law refers to the legal system of statute and common law operating in Northern Ireland since the partition of Ireland established Northern Ireland as a separate jurisdiction within the United Kingdom in 1921.
For the purposes of private international law the United Kingdom is divided into three distinct legal jurisdictions:Northern Ireland is a common law jurisdiction. Although its common law is similar to that in England and Wales, and partially derives from the same sources, there are some important differences in law and procedure between Northern Ireland and England and Wales. While influenced by English law, the Northern Ireland legal system is distinctive for a number of reasons: it has roots in Irish common law prior to Irish independence in 1921; following Irish independence, Northern Ireland became a devolved jurisdiction within the United Kingdom.
Ireland–United Kingdom relations
19th century violent and constitutional campaigns for autonomy or independence culminated in an election in 1918 returning almost 70% of seats to Sinn Féin, who declared Irish independence from Britain and set up a parliament in Dublin, and declared the independence of Ireland from the United Kingdom. A war of independence followed that ended with the Anglo-Irish Treaty of 1922, which partitioned Ireland between the Irish Free State, which gained dominion status within the British Empire, and a devolved administration in Northern Ireland, which remained part of the UK. In 1937, Ireland declared itself fully independent of the United Kingdom.
