In 2007, Roach, along with three others—Michael McAteer, an Irish immigrant with "republican heritage"; Ashok Charles, an Indo-Canadian professional photographer; and Howard Gomberg, a professional actor and performer from the United States—filed a class action lawsuit in the Ontario Superior Court of Justice, claiming that the requirement to take the Oath of Citizenship not only violated the aforementioned sections of the charter, but also clause 2(a), that relating to freedom of conscience. He stated in the media that requiring black people to swear allegiance to the Canadian sovereign to receive citizenship was akin to forcing Jews to swear an oath to a descendant of Adolf Hitler and said in a letter to his fellow litigants: "If we win this class action, a centuries-old tradition would begin to unravel." Though the federal Crown made two attempts to have the case dismissed as frivolous and vexatious, on 20 February 2008, the Ontario Court of Appeal approved the proceeding of the case to the Ontario Superior Court. During the proceedings, the Monarchist League of Canada publicly supported the present oath and opposed Roach's actions and media reaction was also negative, with a number of op-ed pieces denouncing Roach's challenges. Roach's case was dismissed by the Ontario Superior Court in January 2009.
