Supreme Court judge Charalambos Machairas said unions between same-sex couples are groundless, in a decision addressed to the court’s political department on Monday.
The judge said the Supreme Court should sustain a previous ruling by an appeals court nullifying the marriage of two women by the former municipal authority on the island of Tilos in the summer of 2008.
The couple challenged the decision by invoking Article 12 of the European Convention of Human Rights, which does not exclude same-sex couples from the right to marry.
The European Court of Human Rights has fined Greece in 2013 for failing to protect the rights, including domestic partnerships, of the country’s homosexual community. The same court described that there was discrimination to same-sex couples.
Greece and Lithuania are the only EU countries that refuse to grant equal rights to same-sex couples.
