The Ministry of Justice studied proposals for the registration of unmarried couples, including same-sex couples. A comprehensive report was released in July 2009 examining three options: the recognition of unregistered cohabitation; the creation of a partnership registry; and the extension of marriage to same-sex couples. It left the decision over which model to implement to the Riigikogu and other "stakeholders". On July 1, 2010, a new family law was passed, defining marriage as between a man and a woman and declaring unions between members of the same sex "null and void". Prime Minister Andrus Ansip was quoted as saying, "I do not believe that Estonia, Latvia and Lithuania will soon accept same-sex marriage in the eyes of the law".
