On June 26, 2015, the Supreme Court released its decision in Obergefell v. Hodges, which allowed two people of the same sex to be issued marriage licenses in all fifty states. Months earlier during oral argument, Chief Justice John Roberts remarked, "Every definition that I looked up, prior to about a dozen years ago, defined marriage as unity between a man and woman as husband and wife. You're not seeking to join the institution, you're seeking to change what the institution is."
