Pennsylvania Governor Tom Corbett’s Office of General Counsel will take up the defense of the state’s ban on gay marriage after Attorney General Kathleen Kane announced that she wouldn’t defend the measure in a case brought by several same-sex couples who are challenging the 1996 law.

Nearly three weeks after Kane announced that she wouldn’t defend the state law, which she called unconstitutional at a press conference in Philadelphia, General Counsel James Schultz responded with a letter to her office indicating that he would defend the law and he expressed disapproval of her decision. Corbett, a Republican, and Kane, a Democrat, have been at odds over several issues in the past, including Corbett’s plan to privatize Pennsylvania’s lottery.
