On June 26, 2015, the U.S. Supreme Court issued its much-anticipated decision on same-sex marriage. In a landmark decision, the Supreme Court ruled 5-4 that the U.S. Constitution guarantees same-sex couples the right to marry. 

This case, Obergefell v. Hodges, involved challenges to same-sex marriage bans from four states—Ohio, Tennessee, Michigan and Kentucky. Even though the Supreme Court’s decision involves these four states, the ruling affects same-sex marriage laws in every state.

The Supreme Court’s ruling means that same-sex couples have the right to be married in their own states and to have their marriages recognized as valid in every other state.

The Supreme Court’s ruling is effective immediately, which means all states must start (or continue) issuing marriage licenses to same-sex couples on the same terms as opposite-sex couples.
