Suspended Pennsylvania Supreme Court Justice Joan Orie Melvin is asking her colleagues on the high court to put a stop to her upcoming criminal trial on political corruption charges.

In a King’s Bench petition filed with the Supreme Court, Orie Melvin raises the same argument she unsuccessfully made to an Allegheny County Court of Common Pleas judge late last year — that charging her for violating internal court procedures banning political activity is unconstitutional and an abrogation of the court’s exclusive right to supervise itself.
