The Office of the Police Ombudsman for Northern Ireland (OPONI; , Ulster-Scots: Owersman fur tha Polis o Norlin Airlann) is a non-departmental public body intended to provide an independent, impartial police complaints system for the people and police under the Police (Northern Ireland) Acts of 1998 and 2000. Office Structure and Legal Remit The law in Northern Ireland does not permit the police to investigate complaints made by members of the public about the conduct of police officers. These must be referred instead to the Police Ombudsman’s Office for independent investigation. The Office has a complement of around 150, about two thirds of whom are employed within the Office’s investigative teams. There are two main strands to the investigative work of the Office – current and historical. Its current work involves dealing with complaints about the conduct of police officers during incidents which have occurred in the previous 12 months. Legislation also permits the Police Ombudsman's Office to investigate matters involving police officers which he considers to be grave or exceptional, no matter when they took place. These are cases in which police officers may have been responsible for deaths or serious criminality. Complaints being dealt with by the Office include those alleging police involvement in murder, attempted murder, as well as conspiracy and incitement to murder. Most of these historical cases relate to incidents during the conflict in Northern Ireland between 1968 and 1998 (commonly referred to as “The Troubles”). Since opening on 6 November 2000, the Office has dealt with between 2,800 and 3,600 complaints each year. Personnel The Police Ombudsman is Marie Anderson, who was appointed in July 2019, having previously served as Northern Ireland Ombudsman (2016-2019). Mrs Anderson's predecessor was Michael Maguire, who previously served as Chief Inspector, Criminal Justice Inspectorate Northern Ireland (2008–12). Prior to that, Al Hutchinson, who had previously been Police Oversight Commissioner, took up office on 6 November 2007, and retired in January 2011 following a series of critical independent reports. The first Ombudsman for Northern Ireland was Nuala O'Loan, whose seven-year term in office ended in November 2007. She has since been appointed a Dame Commander of the Order of the British Empire and was subsequently appointed to the House of Lords.
