(Harrisburg) -- A federal judge hearing a challenge to Pennsylvania's law banning recognition of same-sex marriages is keeping the case on track for trial by preventing an appellate review at this stage.

U.S. District Judge John Jones has rejected the state's argument that his court lacks the power to hear the case, and suggested that the 3rd U.S. Circuit Court of Appeals would agree with him. 

Jones says there've been ``substantial and far-reaching'' developments in how courts treat equal protection and due process rights since the U.S. Supreme Court's 1972 decision that it lacked the jurisdiction to decide whether a Minnesota law banning same-sex marriages violated the Constitution. 

He says that puts him in a position to hear the case. 

A trial is slated to start on June 9th.
