Constitution (Amendment No. 24) Act 1936

20 of 1934) was an act of the Oireachtas (parliament) of the Irish Free State which abolished Seanad Éireann, the upper house of the Oireachtas, which thenceforth was unicameral, with Dáil Éireann as the sole house.

The bill was introduced in 1934 by the Fianna Fáil government of Éamon de Valera, which was frustrated by the Seanad's repeated use of its power to delay (though not veto) legislation.

In particular, Fianna Fáil favoured eliminating symbols of monarchy from the Free State, which the Seanad, with more Southern Unionist members, feared would antagonise the United Kingdom.

[4] The act deleted 16 articles of the 1922 Constitution and made consequential amendments to numerous others.

Eleven senators of the sixty were to be nominated by the Taoiseach, assisting the likelihood of a government majority.
