On the final day of the committal hearing for Cardinal George Pell in Melbourne, the court has been told that many of the allegations against Cardinal George Pell are simply impossible.

Australia's most senior Catholic is facing multiple charges of historical sexual offences against multiple complainants, but he continues to vehemently deny all of them.

Cardinal Pell's QC also said that many of the complainants are not sufficiently credible witnesses to bring the cases to trial.
