of the population). In response to these rulings, the governing Liberal party minority government introduced legislation to allow same-sex couples to marry. On 20 July 2005, the Canadian Parliament passed the Civil Marriage Act, defining marriage nationwide as "the lawful union of two persons to the exclusion of all others." This was challenged on 7 December 2006 by a motion tabled by the newly elected Conservative party, asking the government to introduce amendments to the Marriage Act to restrict marriage to opposite-sex couples; it was defeated in the House of Commons by a vote of 175 to 123. Canada does not have a residency requirement for marriage; consequently, many foreign couples have gone to Canada to marry, regardless of whether that marriage will be recognized in their home country. In fact, in some cases, a Canadian marriage has provided the basis for a challenge to the laws of another country, with cases in Ireland and Israel. The plaintiff in the case of United States v. Windsor, which challenged the Defense of Marriage Act, wed her wife in Ontario. Since 11 November 2004, the Canadian federal government's immigration department, Citizenship and Immigration Canada (CIC), considers same-sex marriages performed in Canada valid for the purposes of sponsoring a spouse to immigrate. Canadian immigration authorities previously considered long-term, same-sex relationships to be equivalent to similar heterosexual relationships as grounds for sponsorship. Colombia The Colombian Constitutional Court ruled in February 2007 that same-sex couples are entitled to the same inheritance rights as heterosexuals in common-law marriages. This ruling made Colombia the first South American nation to legally recognize same-sex couples. In January 2009, the Court ruled that same-sex couples must be granted all rights offered to cohabiting heterosexual couples. On 26 July 2011, the Court ordered the Congress to pass legislation giving same-sex couples similar rights to marriage within two years (by 20 June 2013). The law was defeated. In April 2016, the Colombian Constitutional Court voted 6–3 to allow same-sex marriage, with the ruling taking effect immediately. In 2015, the Colombian Constitutional Court ruled that same-sex couples could adopt children. Costa Rica In 2016 the government motioned at the Inter-American Court of Human Rights to pass judgement over the rights of same-sex couples. The Court agreed and in 2018 the Court's binding sentence was that Costa Rica (and presumably all the other member states of the Pact of San José) was required to
