Canon 381

Can. 381 §1. A diocesan bishop in the diocese entrusted to him has all ordinary, proper, and immediate power which is required for the exercise of his pastoral function except for cases which the law or a decree of the Supreme Pontiff reserves to the supreme authority or to another ecclesiastical authority.

Can. 381 §2. Those who preside over the other communities of the faithful mentioned in can. 368 are equivalent in law to a diocesan bishop unless it is otherwise apparent from the nature of the matter or from a prescript of law.
