The state attorney general shouldn’t be dismissed from a case challenging Pennsylvania’s ban on same-sex marriage unless the governor is dismissed from the case also, lawyers for the Corbett administration argued in one of the three state-court cases over the law.

The couples who brought the suit in September, represented by Robert Heim of Dechert, filed a joint petition with Attorney General Kathleen Kane last month seeking to dismiss her as a defendant since she “is an unnecessary party,” according to the short petition filed with the Commonwealth Court.
