The Cory Collusion Inquiry was established to conduct an independent inquiry into deaths relating to the 'Troubles' in Northern Ireland. A retired Supreme Court of Canada judge, Peter Cory was appointed to undertake a thorough investigation of allegations of collusion between British and Irish security forces and paramilitaries in six particular cases in Northern Ireland. Two of the cases - the killing of two Royal Ulster Constabulary officers and the killing of Northern Ireland Lord Justice Maurice Gibson and Lady Cecily Gibson - relate to allegations of collusion by the Garda Síochána and these reports were submitted to the Irish government.
