HARRISBURG — Seven years after Jerry Sandusky was convicted of child molestation and sentenced to decades behind bars, an appeals court has ordered a resentencing hearing for the former Penn State assistant football coach.

Sandusky, 75, was sentenced in 2012 to 30 to 60 years, but a Pennsylvania Superior Court panel said that included the improper application of mandatory minimums.

In a 119-page opinion, the appeals panel struck down argument after argument that lawyers for Sandusky had made in seeking a new trial. His defense lawyer, Al Lindsay, said he was disappointed but will ask the state’s highest court to reconsider.

Lindsay said he was unsure if the new sentencing is likely to result in a substantially different sentence.

“I suppose it depends on the judge and what happens before the sentencing and after the sentencing,” Lindsay said. He called the case “one of the most profound injustices in the history of American jurisprudence.”

The state attorney general’s office said it was pleased that Sandusky’s convictions remained intact. “The Superior Court has agreed with our office that it was proper for the court below to reject Sandusky’s claims,” said Joe Grace, a spokesman for the prosecutors.
