Canon 7
If a judge dares punish a cleric of whatever rank by public actions or detain him for whatever reason without the bishop's knowledge and permission, or dares harm him by calumnies or injustice, he should be deprived of communion. At the same time, however, the bishop should not hinder the correction of negligence on the part of the clerics, once again considering the situations [they were involved in].
