While more often than not the Human Rights Tribunal of Ontario’s decisions are not challenged, there are two processes by which this can be done.
Generally speaking, res judicata (Latin for “a thing adjudicated”) is the legal doctrine which prevents the same matter from being tried a second time once there has been a verdict or decision in regard to that matter. Under Ontario's Human Rights Code, a criminal matter being decided in regard to a matter that contains a breach of the Human Rights Code does not necessarily prevent an applicant from filing at the Human Rights Tribunal of Ontario. This was the case in G.G. v. […] Ontario Limited.
The recent Human Rights decision of Rollick v. 1526597 Ontario Inc. o/a Tim Horton’s Store No. 2533, addresses what the Tribunal characterized as "heavy handed and unjustifiable" conduct on the part of the employer, when dealing with an employee with a disability.
