A Philadelphia county defied a state ban on gay marriage Wednesday and issued licenses to five same-sex couples.
The licenses, from Montgomery County, were issued despite a 1996 law that defines marriage as a civil contract between a man and a woman in that state.
They are believed to be the first in Pennsylvania. A battle is expected to play out in court.
The county's district attorney said the licenses are not legally valid in Pennsylvania, but it's not her place to intervene.
Also, the state's attorney general has said she will not defend the gay marriage ban.
