A federal judge on Friday set a June 9 trial date for a lawsuit challenging Pennsylvania's gay marriage ban.

According to the AP, U.S. District Judge John E. Jones II set a timetable for the filling of pre-trial motions during Friday's conference with lawyers.

Last week, Jones denied two separate attempts by state officials to dismiss the lawsuit.

The suit 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.
