A suburban Philadelphia county on Friday morning issued its 100th marriage license to a gay couple in defiance of state law.

Nicole and Virginia Perrine-Wilson received Montgomery County's 100th marriage license.

As of the close of business on Friday, 103 gay and lesbian couples had received marriage licenses from the county since Register of Wills Bruce Hanes announced on July 23 that he believes the state's law limiting marriage to heterosexual unions violates the Pennsylvania Constitution.

“Article 1 Section 1 [of the constitution], which is a sort of preamble, but it does state that we're all entitled to individual liberties and freedoms and happiness,” Hanes told CNN.

So far, 33 of the couples have married, the AP reported.

A challenge to the marriage ban appears to have touched off the burgeoning marriage movement in Pennsylvania.

Hanes announced his decision soon after Attorney General Kathleen Kane, a Democrat, refused to defend the law in court, leaving Governor Tom Corbett, a Republican, to step in. Corbett has also sued Montgomery County to stop it from issuing marriage licenses to gay couples.
