A high-ranking US Catholic church official convicted last year of covering up a child sex abuse scandal has had his conviction overturned.

Monsignor William Lynn was convicted in June 2012 of endangering the welfare of a child by reassigning a priest with a history of sexual abuse to a Philadelphia parish that was unaware of his past.

That priest, Edward Avery, later pleaded guilty to sexually assaulting a 10-year-old altar boy in the Philadelphia parish.

Lynn, who was not accused of personally molesting children, was sentenced to a three-to-six-year prison term.

A Superior Court of Pennsylvania appeals panel reversed his conviction on Thursday, and ordered Lynn to be discharged from prison.
