Law enforcement in Ireland


This is a description of law enforcement in Northern Ireland and the Republic of Ireland. Before the Republic left the union in 1922, one police force — the Royal Irish Constabulary — policed almost the whole island.
The Royal Ulster Constabulary, renamed the Police Service of Northern Ireland in 2001, is the direct descendants of that force, while a new police force — the Garda Síochána — was set up in the Irish Free State. Today, due to the sharing of a land border and legislation introduced to both countries after the Belfast Agreement of 1998, there is cooperation between the main police forces of jurisdictions.

Republic of Ireland

The Republic of Ireland has a single national civilian police force, Garda Síochána na hÉireann. This force is responsible for all aspects of territorial civil policing. The Garda Síochána have been the only territorial police force in the Republic since the disbandment of the Civic Guard gendarmery in 1922, and the incorporation of the Dublin Metropolitan Police in 1925.
In addition to the Gardaí, other policing bodies include the
Law enforcement in Northern Ireland follows a similar model to that of the rest of the United Kingdom in that it is the responsibility of the local territorial police force. However unlike England and Wales, which have police forces divided by local areas such as ceremonial counties or local council areas, Northern Ireland has a single territorial police force, the Police Service of Northern Ireland, formerly known as the Royal Ulster Constabulary. This force, one of the largest geographically in the UK, is responsible for all local policing in the province.
In addition to the PSNI, there are other agencies which have responsibility for specific parts of Northern Ireland's transport infrastructure:
Officers of these forces have full constabulary powers within one mile of the specific locations they police, which come from specific pieces of legislation relating to them.
A further civilian police force with powers in Northern Ireland is the Ministry of Defence Police, which has responsibility for policing all MOD property; they are assisted in this by the Northern Ireland Security Guard Service. Additionally, the Royal Military Police has a presence in British Army barracks.
