Archbishop guilty of concealing child sex abuse

Adelaide Archbishop Philip Wilson was accused of concealing abuse by notorious paedophile priest Jim Fletcher in the New South Wales Hunter region by failing to report the allegations.

His legal team reportedly made four attempts to have the case thrown out, arguing Wilson's diagnosis of Alzheimer's should preclude him from trial -- although it did not prevent him retaining his position in the church.

Magistrate Robert Stone found him guilty at Newcastle Local Court of concealing a serious indictable offence of another person, with the archbishop facing a maximum of two years in jail. Sentencing will be at a later date.

There was no dispute during the hearing that Fletcher, who is now dead, sexually abused altar boy Peter Creigh, but that Wilson, then a junior priest, did nothing about it when he was told.

The Australian Broadcasting Corporation reported from the court that Stone found Creigh to be a truthful and reliable witness.

"I am satisfied and find that Mr Creigh described to the accused he performed fellatio of Fletcher and masturbated Mr Fletcher," he said.

Stone added that he did not accept Wilson could not remember a 1976 conversation in which Creigh described the abuse, saying he "had no motive or interest to deceive or make up the conversation".

The charges laid against Wilson, in 2015, stemmed from the work of Strike Force Lantle, which since 2010 had investigated claims of child abuse concealment by former and current clergy attached to the Maitland-Newcastle Diocese of the Catholic Church.

His conviction is another headache for Pope Francis, whose papacy has been haunted by allegations of sex abuse among Catholic priests.

Last week, 34 Chilean bishops announced their resignation over a child sex abuse scandal.

Several members of the Chilean church hierarchy are accused by victims of ignoring and covering up child abuse by Chilean paedophile priest Fernando Karadima during the 1980s and 1990s.
