The title 'Translation of pre-1970 decisions' over a black and white picture of the courtroom

To mark its 150th anniversary, the Supreme Court of Canada is translating some of its most significant decisions rendered prior to the coming-into-force of the Official Language Act in 1970. We are pleased to share the first completed translation from this initiative: Roncarelli v. Duplessis (1959).

This translation is part of a broader effort guided by an independent committee of legal experts which recommended 24 significant Supreme Court decisions that should, in their opinion, be translated. Read the full decision.
