MADISON, Wis. — A stinging rejection of same-sex marriage bans in Wisconsin and Indiana, issued by a unanimous and unequivocal U.S. appeals court, has brought hope to those fighting the laws that the Supreme Court will feel pressure to rule soon in their favor.

The ruling from the 7th U.S. Circuit Court of Appeals in Chicago came Thursday, the same day 32 states asked the Supreme Court to settle the issue once and for all.

Fifteen states that allow gay marriage, led by Massachusetts, filed a brief asking the justices to take up three cases from Virginia, Utah and Oklahoma and overturn bans. And 17 other states, led by Colorado, that have banned the practice asked the court to hear cases from Utah and Oklahoma to clear up a “morass” of lawsuits, but didn’t urge the court to rule one way or another.

Celebrations Thursday over the latest legal victory for gay couples seeking to get married were tempered knowing that the bigger — and final — battle rests with the high court.

Same-sex marriage is legal in 19 states and the District of Columbia. Bans that have been overturned in some other states continue to make their way through the courts. Since last year, the vast majority of federal rulings have declared same-sex marriages bans unconstitutional.
