The Third Amendment of the Constitution Bill 1958 was a proposal to amend the Constitution of Ireland to alter the electoral system from proportional representation under the single transferable vote (PR-STV) to first-past-the-post (FPTP). The proposal was rejected in a referendum held on 17 June 1959. This was the same date as the presidential election in which Taoiseach Éamon de Valera was elected as president.

Background

Proportional representation by means of the single transferable vote had been used in Irish elections since the 1920 local elections. Under the Government of Ireland Act 1920, it was prescribed for elections to both the Southern Ireland House of Commons and the Northern Ireland House of Commons (Northern Ireland was to revert to FPTP for the 1929 election). The Constitution of the Irish Free State, adopted on independence in 1922, prescribed proportional representation for elections to Dáil Éireann. Under the Constitution of Ireland adopted in 1937, Article 16.2.5° prescribed PR-STV, while 16.2.6° specified that the number of members in a constituency would not be less than three. An amendment to the 1937 constitution must be proposed as a bill initiated in the Dáil and be passed or deemed to have been passed in both the Dáil and the Seanad, before being submitted to a referendum in which all Irish citizens on the electoral register are eligible to vote.

Proposal

The amendment proposed to alter the electoral system for elections to Dáil Éireann to first-past-the-post (FPTP) under single-seat constituencies. It also proposed to establish an independent commission for the drawing of constituency boundaries on a constitutional basis. It was introduced by the Fianna Fáil government of Éamon de Valera but was opposed by Fine Gael, the main opposition party, and by the Labour Party.

Oireachtas debate

The amendment was proposed by Taoiseach Éamon de Valera on 12 November 1958. It passed the Dáil on 28 January 1959 by 74 votes to 55. On 19 March 1959, it was rejected in the Seanad by 29 votes to 28. Under Article 23.1, the Dáil may vote to deem a bill to have been passed by the Seanad by a resolution passed after a period of 90 days from being sent by the Dáil to the Seanad. On 13 May 1959, the Dáil passed such a resolution by 75 votes to 56, and the bill proceeded to a referendum.
