Thirty-fourth Amendment of the Constitution of Ireland
The Thirty-fourth Amendment of the Constitution (Marriage Equality) Act 2015 (previously bill no. 5 of 2015) amended the Constitution of Ireland to permit marriage to be contracted by two persons without distinction as to their sex. Prior to the enactment, the Constitution was assumed to contain an implicit prohibition on same-sex marriage in the Republic of Ireland. It was approved at a referendum on 22 May 2015 by 62% of voters on a turnout of 61%. This was the first time that a state legalised same-sex marriage through a popular vote. Two legal challenges regarding the conduct of the referendum were dismissed on 30 July by the Court of Appeal, and the bill was signed into law by the President of Ireland on 29 August. An amendment to the Marriage Act 2015 provided for marriages permitted by the new constititional status. The act came into force on 16 November 2015; the first same-sex marriage ceremony was held on 17 November 2015.
