William Basil McIvor OBE, PC (NI) (17 June 1928 – 5 November 2004) was an Ulster Unionist politician, a minister in Northern Ireland's first power-sharing Executive, a barrister and a pioneer of integrated education.
Disregarding a message from Cardinal William Conway "not to interfere with the schools", McIvor, with Faulkner's support brought the proposal to the Executive where he recalls it being welcomed by all, save Hume.
McIvor believed that much of the responsibility lay with the determination of the Unionists' Social Democratic and Labour Party partners to "achieve all-Ireland institutions that would produce the dynamic that could lead ultimately to an agreed single state of Ireland".
[6]: 104 (After the 1998 Belfast Agreement, McIvor did allow that Hume had "courageously done much to promote peace in Northern Ireland within the context of his nationalist aspirations, and [had] been a force in compelling Unionists, and rightly so, to engage in dialogue with their arch enemy, Sinn Féin).
In 1987, he was subject of a motion tabled in the United Kingdom House of Commons by four UUP MPs who accused him of showing bias against unionists and members of the Orange Order in a County Antrim case and so demanded McIvor's removal from the bench.
