The third reconstitution of the board in 2007 was historic as Sinn Féin took up its seats on the Policing Board following the party's decision to support 'civic policing' by the PSNI at its ardfheis on 28 January 2007. Sinn Féin was associated in the past with the Provisional Irish Republican Army (PIRA), which killed 271 Royal Ulster Constabulary officers and 12 police officers outside Northern Ireland during the Troubles, and had refused to recognise the legal authority of the RUC or PSNI until that point.
