 In the 1120s, Bishop Peter caused considerable trouble by illegally and uncanonically taking control of five parishes belonging to the diocese of Bobbio.The Bishop of Bobbio complained to the Pope, and therefore, on 26 November 1128, Pope Honorius II decreed that Bishop Peter should return those churches immediately; if he still had issues, he could bring them to the papal Court.In 1180 Bishop Oberto was one of four bishops who were found to be illegally occupying parishes belonging to the Monastery of S. Maria Theodota, and they were all ordered by Pope Alexander III to return the lands in question.
