Latta v. Otter, 771 F.3d 456 (9th Cir. 2014) is a court case that resulted from a federal lawsuit filed by four couples from Boise, Idaho, where same-sex marriage remained illegal until the couples' victory in 2014. Prior to Latta v. Otter, only 16 U.S. states had legalized same-sex marriage, and Idaho refused to recognize same-sex marriages performed in such states. On September 8, 2014, the Ninth Circuit ruled that Idaho's ban on same-sex marriage was a violation of the U.S. Constitution's guarantee of equal protection.
