The Supreme Court decided today to review the right of states to ban same-sex marriage. The Court granted certiorari in four cases, all from the Sixth Circuit (Kentucky, Michigan, Ohio, and Tennessee), whose U.S. Court of Appeals had upheld state bans. Here are the issues on which the Court will hear argument:

1) Does the Fourteenth Amendment require a state to license a marriage between two people of the same sex?

2) Does the Fourteenth Amendment require a state to recognize a marriage between two people of the same sex when their marriage was lawfully licensed and performed out-of-state?

More information is available on the excellent SCOTUSblog. Oral argument is expected in the spring, and a decision sometime in June.
