The Council of Ireland, that Mallon's party colleague, Hugh Logue, had referred to as "the vehicle that would trundle Unionists into a united Ireland"CAIN: Sunningdale – Chronology of Main Events , cain.ulst.ac.uk; accessed 4 April 2020. was replaced by a North-South Ministerial Council. "Not a supra-national body", and with no "pre-cooked" agenda, the Council was accountable to the Assembly where procedural rules (the Petition of Concern) allowed for cross-community consent, and hence a "unionist veto".Trimble (1998), pp. 1155–1157
