EDITOR'S NOTE: The High Court overturned Cardinal George Pell's conviction for historic child sex offences in a judgment handed down April 7, 2020. In a unanimous decision all seven High Court judges found Victoria's Court of Appeal should not have upheld Pell's conviction It found the evidence could not support a guilty verdict.

Prison authorities are investigating whether disgraced cardinal George Pell broke prison rules after a letter he apparently wrote to supporters, comparing his suffering to that of Jesus, was posted on social media.

Written from the Melbourne Assessment Prison and dated August 1, the letter apparently written by Pell discusses how his faith is helping him in prison and the upcoming synod on the Amazon.

The letter was posted late on Friday night by the ‘Cardinal George Pell Supporters’ Twitter feed.

A Department of Justice and Community Safety spokeswoman on Saturday said prisoners are denied any access to the internet or social media, and it is a prison offence to "commission other individuals to post something on social media on behalf of a prisoner".
