Same-sex marriage has been legally recognized in the U.S. state of Wisconsin since October 6, 2014, upon the resolution of a lawsuit challenging the state's ban on same-sex marriage. On October 6, the U.S. Supreme Court refused to hear an appeal of an appellate court ruling in Wolf v. Walker that had found Wisconsin's ban on same-sex marriage unconstitutional. The appellate court issued its order prohibiting enforcement of the state's ban on same-sex marriage the next day and Wisconsin counties began issuing marriage licenses to same-sex couples immediately.
