Eight former Beta Theta Pi fraternity brothers are scheduled for a new preliminary hearing, according to WJAC-TV.
A new judge would preside over the hearing because President Judge Pamela Ruest granted a motion to reinstate charges, including involuntary manslaughter, on Monday.
"The Commonwealth in good faith has alleged improper dismissal by Magisterial District Judge (Allen) Sinclair," Ruest said in the order.
The Office of the Attorney General filed the motion in April after District Judge Sinclair dismissed a majority of charges filed against 11 former fraternity brothers.
"We will continue seeking justice for the Commonwealth and Tim Piazza and to hold every defendant accountable," spokesman for the Office of the Attorney General Joe Grace said. "Our case moves forward."
Tom Kline, attorney for Jim and Evelyn Piazza, said he is hopeful Ruest's order is a turn in the right direction.
"We are hopeful that this is a turn in the right direction in this long road to justice for parents of Tim Piazza," Kline said.
All eight attorneys for the former fraternity brothers did not respond to requests for comment.
