A federal judge on Friday rejected two separate attempts to dismiss a lawsuit challenging Pennsylvania's gay marriage ban.

According to the AP, U.S. District Judge John E. Jones III denied the motions filed by Pennsylvania's secretaries of the department of Health and Revenue and Bucks County's register of wills.

Jones advised lawyers to be “fully prepared” to discuss a trial date during a scheduled November 22 conference.

The lawsuit is one of at least six filed in recent months challenging Pennsylvania's 17-year-old law that defines marriage as a heterosexual union and prohibits the recognition of marriages entered into by gay couples under the laws of another state.

The lawsuit ignited a chain of events that led to the additional challenges.

After Pennsylvania Attorney General Kathleen Kane said she could not defend the state's law because it was unconstitutional, Montgomery County Register of Wills Bruce Hanes independently began issuing marriage licenses to gay couples.

Hanes issued 174 marriage licenses before a court ordered him to stop.

Several couples who married with licenses obtained in Montgomery County filed separate lawsuits asking the courts to recognize their marriages as valid.
