Cardinal Angelo Becciu will face the first hearing of his appeal on Monday in a trial that has gripped the Vatican for more than four years.

The 77-year-old cardinal, once among the most powerful figures in the Curia, was convicted in December 2023 of embezzlement, aggravated fraud and abuse of office, and sentenced to five and a half years in prison.

The appeal, formally designated Protocol No. 26/23 RGPCA, will be heard by the Vatican Court of Cassation, the highest judicial body of the Holy See. Proceedings are scheduled to open at 8am in the newly inaugurated courtroom within the Apostolic Palace, a space created from the old Synod Hall and visited by Pope Francis earlier this month.
