The Court of Appeal will hand down its judgment on Wednesday from 9.30am. It will be live-streamed from the Supreme Court website. Supreme Court Chief Justice Anne Ferguson, Justice Chris Maxwell, the president of the Court of Appeal, and Justice Mark Weinberg could overturn the convictions, uphold them, or order a retrial.

Firstly, Pell's team claims County Court Chief Judge Peter Kidd should have allowed the defence to play a 19-minute 'Pac-Man'-style video, with coloured dots representing where they say people would have been in St Patrick's Cathedral during Sunday Mass in December 1996. The prosecution protested that the jury might view the video as an accurate reconstruction of where people were.

Another ground says there was a "fundamental irregularity" because Pell was not arraigned – asked if he pleaded guilty or not guilty – directly in front of the chosen jury. The other claim is that the jury reached an unreasonable verdict. What could happen to Pell from here If the judges agree with the third ground for appeal and find the verdict was unsafe, Pell's convictions would be quashed and he would be released.

The defence team's video and arraignment grounds are considered technicalities. If the judges agree with these, a retrial is likely. Loading The Court of Appeal could also overturn one or more of Pell's convictions while upholding others. If the judges uphold all convictions, Pell's fight to clear his name and walk free from prison could go to the High Court. If he's let off, prosecutors could also take the Court of Appeal's ruling to the High Court.

Even though it is a matter for the Court of Appeal, the case has been heard at the larger Supreme Court building in Melbourne to cater for the intense interest. There will also be a spillover room to cater for the global media interest. In December, Pell became the world's highest ranking Catholic to be found guilty of sexual abuse. A jury found he orally raped one choirboy and sexually molested another in the St Patrick's Cathedral sacristry in December 1996. The boys from St Kevin’s College were both aged 13 at the time.
