Key Facts

Pre-Obergefell State-by-State Legalization

Before the 2015 Supreme Court decision, marriage equality developed gradually across the United States. Massachusetts became the first state to legalize same-sex marriage in 2004. Over the following years, individual states and courts progressively legalized marriage equality through legislative action and court decisions. By mid-2015, 37 states had already legalized same-sex marriage, but the legal landscape remained fragmented, with some states continuing to ban same-sex marriage.

The Obergefell v. Hodges Decision

On June 26, 2015, the U.S. Supreme Court issued a landmark ruling in the case Obergefell v. Hodges. The court voted 5-4 to strike down state bans on same-sex marriage and require all states to recognize same-sex marriages performed in other states. Justice Anthony Kennedy wrote the majority opinion, emphasizing that the right to marry is fundamental. The decision effectively legalized same-sex marriage throughout the entire United States in a single ruling.

Constitutional Foundation

The Supreme Court's decision was grounded in the 14th Amendment to the U.S. Constitution, specifically the guarantee of equal protection and due process. Justice Kennedy's opinion stated that denying same-sex couples the right to marry violated these constitutional protections. The ruling recognized marriage as a fundamental right that cannot be denied based on sexual orientation. This constitutional foundation made the decision binding on all states and federal agencies.

Federal Rights and Benefits

With the Obergefell decision, same-sex married couples gained access to numerous federal benefits and protections previously available only to opposite-sex couples. These include federal tax benefits, Social Security spousal and survivor benefits, federal employee health benefits, military spousal benefits, and immigration sponsorship rights. Additionally, same-sex couples gained inheritance rights, hospital visitation rights, and adoption rights on a federal level.

National and Global Significance

The Obergefell decision was celebrated as a historic victory for LGBTQ+ rights and civil equality. The ruling demonstrated significant social progress, as polls showed approximately 60% of Americans supported same-sex marriage by 2015. The United States joined other countries in recognizing marriage equality as a fundamental right. The decision continues to influence how courts and legislatures address LGBTQ+ rights and discrimination issues nationwide.
