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.
Northern Ireland Constitution Act 1973
When the Republic of Ireland ceased to be a member of the British Commonwealth, Westminster had responded with the Ireland Act 1949. Amongst its other provisions, the Act had guaranteed that Northern Ireland would not cease to remain a part of the United Kingdom "without the consent of the Parliament of Northern Ireland" (s. 1(2)); this declaration had proven to be controversial both with the Irish government and with Northern Ireland's nationalist community.
