In March 2018, the Supreme Court of the Philippines approved the scheduling of a same-sex marriage petition that seeks to invalidate Articles 1 and 2 of the Family Code.

[3] During the second week of June 2018, the Supreme Court announced that they will hear arguments in a case seeking the invalidation of the Family Code's provisions prohibiting same-sex marriage.

[5] On June 19, 2018, oral arguments commenced with the following arguments made: whether or not the petition is properly the subject of the exercise of the Supreme Court's power of judicial review, whether or not the right to marry and the right to choose whom to marry are cognates of the right to life and liberty, whether or not the limitation of civil marriage to opposite-sex couples is a valid exercise of police power, whether or not limiting civil marriages to opposite-sex couples violates the Equal Protection Clause, whether or not denying same-sex couples the right to marry amounts to a denial of their right to life and/or liberty without due process of law, whether or not sex-based conceptions of marriage violate religious freedom, whether or not a determination that Articles 1 and 2 of the Family Code are unconstitutional must necessarily carry with it the conclusion that Articles 46(4) and 55(6) of the Family Code (i.e.: homosexuality and lesbianism as grounds for annulment and legal separation) are also unconstitutional, and whether or not the parties are entitled to the reliefs prayed for.

"[11] Falcis III described the decision as a "temporary setback" and has already considered the fact that oral arguments were held regarding his case as a victory "for the opportunity to educate the public" about the issue of same sex marriage in the country.

[13] Roman Catholic bishops praised the dismissal of the petition interpreting the high court's decision as a defense for the "sanctity of marriage".
