The state Supreme Court has denied the Philadelphia District Attorney Office’s attempt to reinstate the ­conviction of Monsignor William J. Lynn, the first Catholic Church administrative ­official convicted over sexual abuse committed by other priests.

The justices issued a one-page order Tuesday denying the prosecutor’s appeal in Commonwealth v. Lynn. The District Attorney’s Office had asked the court to reverse a decision from the Superior Court that had vacated Lynn’s child endangerment conviction, and ordered a new trial in the case.
