Philadelphia's district attorney wants an appeals court to take another look at the case of a Roman Catholic church official whose conviction over his handling of sex-abuse cases was overturned last week.

Monsignor William Lynn has been imprisoned intermittently since his 2012 trial.

District Attorney Seth Williams says in a statement he has filed an application for a re-argument of Lynn's case before the full state Superior Court. He says the filing is in response to a decision by a three-judge panel on Tuesday to award a new trial to Lynn.

Williams is to formally announce the filing at a news conference Monday.

The appeals court panel said the trial judge erred in allowing weeks of testimony from 21 accusers to show how the Archdiocese of Philadelphia handled sex-abuse complaints.
