Same-sex marriage is recognized, but not performed in Israel.

International level

Several attempts have been made to establish a right to same-sex marriage at the international level through strategic litigation, at the Human Rights Committee of the United Nations and at the European Court of Human Rights, both of which currently have not yet recognized an equal right to marry for same-sex couples. The Human Rights Committee case was in 1999, with two same-sex couples as the plaintiffs/petitioners and the government of New Zealand as the defender/respondent. The ECHR case, Schalk and Kopf v Austria, was in 2010, with a same-sex couple as the plaintiffs/petitioners and the government of Austria as the respondents. Although both New Zealand and Austria then responded against the petitions then in each case, both countries now legally recognize same-sex marriage. However, new cases were raised regarding same-sex marriage recognition, e.g. Andersen v. Poland.^[1]

Inter-American Court of Human Rights ruling

On 8 January 2018, the Inter-American Court of Human Rights (IACHR) ruled that the American Convention on Human Rights mandates and requires the legalisation of same-sex marriage. The landmark ruling was fully binding on Costa Rica and set binding precedent in the other signatory countries. The Court recommended that governments issue temporary decrees legalising same-sex marriage until new legislation is brought in. The ruling applies to the countries of Barbados, Bolivia, Chile, Costa Rica, the Dominican Republic, Ecuador, El Salvador, Guatemala, Haiti, Honduras, Mexico, Nicaragua, Panama, Paraguay, Peru and Suriname. The Costa Rican Government subsequently announced that it would implement the ruling "in its totality",^[2] and the Government of Panama has also signalled that it would accept the ruling.^[3]^[4]

Furthermore, the Court ruled that the term "spouse" is gender-neutral, and that it does not necessarily imply a person of the opposite sex.^[6]^[7]
