A federal appeals court ruled on Tuesday that it will not review a three-judge panel’s decision to overturn California’s Proposition 8, which banned same-sex marriage.

Following this ruling by the U.S. 9th Circuit Court of Appeals, Proposition 8 proponents plan to appeal the case to the U.S. Supreme Court, putting the battle for same-sex marriage on a national stage. The Supreme Court could decide to hear the case as part of its docket next year. …

In February, a three-judge panel in California voted 2 to 1 against the voter-approved same-sex marriage ban, upholding an earlier decision by Judge Vaughn Walker. The panel said that by denying marriage rights, Proposition 8 violated the equal protection clause and due process clause of the U.S. Constitution.
