On 28 January 1289 he is mentioned as having been an Auditor in the case involving the canonical election of a bishop of Avignon. Two days later he was assigned the task of consecrating the newly approved Archbishop of Crete. In September 1290 Cardinal Giovanni served on the examination committee that investigated the contested election to the Bishopric of Alatri. In March 1291 he was a member of the committee that reviewed the election of the Abbot of S. Albans. At nearly the same time, he did the same in the case of the monastery of S. Pietro in Perugia.
