After the signing of the Anglo-Irish Agreement of 1985, unionist politicians Christopher and Michael McGimpsey brought a suit against the Irish government in the High Court arguing that the Agreement was unconstitutional by Articles 2 and 3, because it recognised that Northern Ireland was part of the United Kingdom. This argument was unusual coming from unionists because of the traditional unionist opposition to these two articles, but was done to discredit an agreement they opposed, albeit not for the reasons they opposed it. Their case failed in the High Court, and again on appeal to the Supreme Court.
