The Constitution (Removal of Oath) Act 1933 (act no. 6 of 1933, previously bill no. 2 of 1932), an Act of the Oireachtas of the Irish Free State amending the Constitution of the Irish Free State and the Constitution of the Irish Free State (Saorstát Eireann) Act 1922, is passed on May 3, 1933. The Act removes the Oath of Allegiance required of members of the Oireachtas and of non-Oireachtas extern ministers.
The oath, pledging allegiance to the Constitution and fidelity to George V as King of Ireland, is required by the Anglo-Irish Treaty signed in 1921, and has been the symbolic focus of Irish republican opposition to the Treaty in the 1922–23 Irish Civil War. When Fianna Fáil is founded in 1926 by veterans of the losing anti-Treaty side in the Civil War, abolishing the oath is a core aim. It is a main item in the manifesto for its successful 1932 Irish general election campaign, after which it forms a minority government whose first action is to introduce the Constitution (Removal of Oath) Bill 1932. Seanad Éireann has more ex-unionists and others conciliatory towards the United Kingdom, and vote to reject the bill unless the Treaty can be amended by agreement. After the 1933 Irish general election, the Fianna Fáil majority government is able to override the Seanad and enact the law.
As well as amending the Constitution, the 1933 act also amends the Constitution of the Irish Free State (Saorstát Eireann) Act 1922, which had both created the Constitution in Irish law and also prohibited any Constitutional amendment incompatible with the Treaty. Since the Free State cannot unilaterally amend the Treaty, Fianna Fáil amends the 1922 act to remove the Treaty’s precedence over the Constitution. Later constitutional amendments are also incompatible with the terms of the Treaty, in particular by weakening and ultimately abolishing the office of Governor-General of the Irish Free State. There is legal controversy over whether the Oireachtas has the power to amend the 1922 act, because it had been passed by the Third Dáil sitting as a constituent assembly before the Oireachtas had come into being. In 1935 the Judicial Committee of the Privy Council (JCPC) in London rules that, in British law, the Oireachtas does have the power, under the Statute of Westminster 1931. Irish jurisprudence takes issue with many of the assumptions underlying the 1935 decision.
The question is rendered moot with the adoption of the Constitution of Ireland in 1937 which repeals the Free State Constitution. The 1933 act is itself repealed as spent by the Statute Law Revision Act 2016.
