[1] On 27 February 1973, with Peter McVeigh and William Meehan, Corey ambushed members of the Royal Ulster Constabulary in Aghalee.
[3] The commission ruled on 15 August 2011 that it was "satisfied that Mr Corey had become involved in the Continuity Irish Republican Army from early 2005 and that he was in a position of leadership in that organisation from 2008 until his recall to prison".
[3] The decision was subject to judicial review by Justice Treacy, who ruled on 9 July 2012 that the hearing's reliance on secret evidence violated Corey's right to due process.
[3][7] The Appeal court under Declan Morgan ruled that, whatever flaws might be in the parole commission's process, Justice Treacy did not have the authority to release Corey or grant him bail.
[4] On appeal he was allowed to attend the church service, though not the burial, on condition that he be accompanied by Sinn Féin MLA John O'Dowd and lifelong friend and official spokesperson Jim McIlmurray from Lurgan.
