[12]           The requirement of notice is to ensure that governments have a full opportunity to support the constitutional validity of their legislation, or to defend their action or inaction, and to ensure that courts have an adequate evidentiary record in constitutional cases. The notice requirements depend on whether a constitutional remedy is sought and whether the remedy falls under s. 52(1) of the Constitution Act, 1982 or ss. 24(1) or 24(2) of the Charter.
