The Constitution (Amendment No. 17) Act 1931 (Act no. 37 of 1931, previously bill no. 40 of 1931),[1] popularly called the Public Safety Act 1931, was an Act of the Oireachtas of the Irish Free State amending the Constitution of the Irish Free State. It inserted Article 2A which empowered the Executive Council to declare a state of emergency during which most provisions of the constitution could be suspended and extra security measures taken. These measures included the uses of the Constitution (Special Powers) Tribunal, a military tribunal, to try civilians for political offences, granting extra powers of search and arrest to the Garda Síochána (police), and the prohibition of organisations deemed a threat to the state's security.
The military tribunal was motivated in part by jury intimidation in trials of republican activists.[3]
The opposition Fianna Fáil party condemned the act and ended the emergency when it took office after the 1932 election. However, in 1933 it reinstated the emergency and banned the Blueshirts, and in 1936 the IRA was banned again. In the landmark 1934 case State (Ryan) v. Lennon, the Supreme Court of Ireland held that the Oireachtas had not acted ultra vires in passing the 1931 act.[4][5]
The Act became obsolete on the repeal of the 1922 Constitution by the Constitution of Ireland in 1937, and was formally repealed by the Statute Law Revision Act 2016.[6]
