The Reference re Remuneration of Judges of the Provincial Court (P.E.I.) 3 S.C.R. 3 is a leading opinion of the Supreme Court of Canada in response to a reference question regarding remuneration and the independence and impartiality of provincial court judges. Notably, the majority opinion found all judges are independent, not just superior court judges and inferior court judges concerned with criminal law, as the written constitution stipulates. Unwritten constitutional principles were relied upon to demonstrate this, indicating such principles were growing in importance in constitutional interpretation. The reference also remains one of the most definitive statements on the extent to which all judges in Canada are protected by the Constitution.
