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.
[5] The Cumann na nGaedheal governments of 1922–32 sought to minimise appeals to the Privy Council as undermining the autonomy of the Free State and giving fuel to its republican opponents.
Article XII of the 1921 treaty provided for a three-person Irish Boundary Commission to finalise the border between the Free State and Northern Ireland.
In the runup to that UK statute, Cosgrave's government prepared two bills for the Free State Oireachtas (parliament): one to remove Article 66 from the constitution, and the other to make any Supreme Court decision final.
[12] The bills had not been introduced by the 1932 general election after which Fianna Fáil came to power after and began removing British and monarchist elements from the constitution.
