On 7 February 2008, the Policing Board decided to appoint a panel of independent experts to re-review the police investigation of the Omagh bombing. Some of the relatives of the bombing victims criticised the decision, saying that an international public inquiry covering both the Republic of Ireland and Northern Ireland should be established instead. The review was to determine whether enough evidence existed for further prosecutions. It would also investigate the possible perjury of two police witnesses made during the trial of suspect Sean Hoey.
