The passage of the Canadian Charter of Rights and Freedoms in 1982 allowed for the provision of challenging the constitutionality of laws governing prostitution law in Canada in addition to interpretative case law. Other legal proceedings have dealt with ultra vires issues (whether a jurisdiction, such as a Provincial Government or municipality, has the powers to legislate on the matter). In 2013, three provisions of the current law were overturned by the Supreme Court of Canada, with a twelve-month stay of effect. In June 2014, the Government introduced amending legislation in response.
