However, prior to 1949, the Supreme Court did not constitute the court of last resort: litigants could appeal to the Judicial Committee of the Privy Council in London. As well, some cases could bypass the court and go directly to the Judicial Committee from the provincial courts of appeal. The Supreme Court formally became the court of last resort for criminal appeals in 1933 and for all other appeals in 1949. The last decisions of the Judicial Committee on cases from Canada were made in the mid-1950s, as a result of their being heard in a court of first instance prior to 1949.
