Beyond lawful authority. A statute is ultra vires, and therefore invalid, if Canada's Constitution Act does not authorize the legislature that passed it to legislate on that matter. Regulations too may be ultra vires the statute they are made under. The opposite is intra vires, within lawful authority.

Without jurisdiction or authority.
