The United States Supreme Court will review the decision by the 9th U.S. Circuit Court of Appeals that struck down Proposition 8, a 2008 law which banned gay marriage in California.

The appeals court's ruling was issued in February and found the law unconstitutional.

The court will also hear a challenge to the Defense of Marriage Act.

According to SCOTUS Blog, the court is expected to hear arguments in late March and make a decision in late June:

The AP reports:

WASHINGTON — The Supreme Court will take up California's ban on same-sex marriage, a case that could give the justices the chance to rule on whether gay Americans have the same constitutional right to marry as heterosexuals.

The justices said Friday they will review a federal appeals court ruling that struck down the state's gay marriage ban, though on narrow grounds. The San Francisco-based appeals court said the state could not take away the same-sex marriage right that had been granted by California's Supreme Court.
