It's the first case of several marriage equality challenges expected to be filed with the nation's highest court.
The decision is being hailed by activists as a major milestone in the fight for marriage nationwide.
Sen. Orrin Hatch, a conservative Republican from Utah, says anyone who doesn't believe marriage equality will soon be the law of the land 'just isn't living in the real world.'
In a news conference, Gov. Gary Herbert expresses displeasure with officials in other states who won't defend bans on same-sex marriage, and he comes close to saying being gay is a choice.
A federal judge orders the state to recognize the unions of those same-sex couples who married in the brief period when such marriages were legal -- but the state will have a chance to appeal.
The fight over marriage equality has immediate consequences for families in Utah.
