Until 1933, Article 66 of the Constitution of the Irish Free State permitted appeals of decisions of the Supreme Court of the Irish Free State to be made to the Judicial Committee of the Privy Council (JCPC) in London. This was a requirement of the Anglo-Irish Treaty of 1921, which underpinned the creation of the Irish Free State. The treaty specified that the Free State's constitutional status would be the same as Canada, another British Dominion, whose local courts allowed further appeal to the JCPC.
