The government of Ireland held referendums on 22 May 2015 on two proposed amendments to the Constitution of Ireland which had been recommended by the Constitutional Convention.[1] The amendment to permit same-sex marriage in the Republic of Ireland was approved by 62–38% of the voters.[2] The other amendment would have reduced the age of candidacy for the President of Ireland from 35 to 21, but voters rejected it by 73–27%. A Dáil by-election in Carlow–Kilkenny was held on the same day.[2] Other amendments were considered but not proceeded with, including reducing the voting age from 18 to 16, and sanctioning the establishment of a Unified Patent Court.[3][4]
