English: Katherine Zappone and Ann Louise Gilligan lost a case in the High Court in 2006 for the recognition by Ireland of their Canadian same-sex marriage. The Civil Partnership and Certain Rights and Obligations of Cohabitants Act 2010 instituted civil partnership in Irish law. After the 2011 general election, the Fine Gael and Labour parties formed a coalition government, whose programme included the establishment of a Constitutional Convention to examine potential changes on specified issues, including "Provision for the legalisation of same-sex marriage". The Convention considered the issue in May 2013 and voted to recommend that the state should be required, rather than merely permitted, to allow for same-sex marriage. Its report was formally submitted in July and the government formally responded in December, when Taoiseach Enda Kenny said a referendum would be held on 22 May, 2015.
