Summary:

This case arose out of the imposition of a mining tax on several mining companies by the Province of Saskatchewan. The tax was imposed pursuant to s. 25A of the Mineral Tax Act. The mining companies commenced an action against the Province of Saskatchewan to challenge the imposition of the tax. The Province of Saskatchewan pleaded s. 5(7) of the Proceedings Against the Crown Act which granted the Crown immunity from suit for acts done pursuant to a statute declared to be beyond the legislative competence of the Province of Saskatchewan. In an interlocutory proceeding the mining companies applied for an order with respect to their right to recover taxes paid in the event of the invalidity of s. 25A of the Mineral Taxation Act. The Court of Queen's Bench dismissed the application by the mining companies.

On appeal by the mining companies to the Saskatchewan Court of Appeal the appeal was dismissed.

On appeal to the Supreme Court of Canada the appeal was allowed. The Supreme Court of Canada declared that s. 5(7) of the Saskatchewan Proceedings Against the Crown Act was ultra vires the Province of Saskatchewan. The Supreme Court of Canada declared that s. 5(7) of the Proceedings Against the Crown Act did not bar the mining companies from recovering taxes paid before a declaration of invalidity with respect to s. 25A of the Mineral Taxation Act. The Supreme Court of Canada stated that where a statute is found to be ultra vires, then any statute, which attaches legal consequences to acts done pursuant to the invalid law, must equally be ultra vires - see paragraph 25.
