Cardinal George Pell's final bid to overturn his convictions for child sexual abuse has begun hearings in Australia's top court.
The ex-Vatican treasurer is serving a six-year jail sentence after a jury found he abused two boys in a Melbourne cathedral in the 1990s.
Pell is the most senior Catholic priest ever to be found guilty of such crimes.
He is seeking to challenge the verdict by arguing that the jury did not properly consider all evidence.
The Australian cleric, 78, has maintained his innocence since he was charged by police in June 2017.
