Montgomery County has issued its 100th same-sex license as it continues to defy Pennsylvania's marriage law.

The county Democrats behind the move said they believe the state ban on gay marriage is unconstitutional.

It's unclear whether the practice will survive a legal challenge from Republican Gov. Tom Corbett's administration.

The American Civil Liberties Union hopes to overturn the state ban in federal court.

Nicole and Ginny Perrine-Wilson, of Lansdowne, picked up the 100th same-sex license Friday. They've been together 15 years and share a last name and daughter.

Ginny Perrine-Wilson said the couple doesn't expect to reap all the benefits of marriage right away, given the ongoing legal fight, but she said they want to marry in Pennsylvania and be part of the movement that changes the law.
