Pell yet to decide on High Court appeal

No decision has yet been made on whether Cardinal George Pell will appeal his sex abuse convictions to the High Court despite reports he plans to do so, a spokeswoman for the cleric says.

It's Pell's last chance at an appeal after Victoria's Court of Appeal last week upheld his December conviction for the rape of a 13-year-old choirboy and sexual assault of another at St Patrick's Cathedral in Melbourne in 1996.

Victorian Supreme Court Chief Justice Anne Ferguson and President Chris Maxwell on Wednesday ruled 2-1 to overrule Justice Mark Weinberg's judgment for his acquittal.

Pell, 78, reportedly received unanimous advice from his legal team that the dissenting opinion of Justice Weinberg provided reasonable grounds to have his convictions overturned, The Age and The Sydney Morning Herald reported on Sunday.

Despite the media reports, a spokeswoman for Pell told AAP on Sunday that no decision had been made yet.

Pell's lawyers have 28 days to file the appeal application, if they determine there are grounds to push ahead. That application needs to be granted before the High Court can hear any appeal.

A single judge would hear the application, considering factors including whether the case is a matter of public importance, whether the decision relates to a matter of law, or if it's in the interests of the administration of justice.
