16 Owing to the fact that the faithful of the different individual churches dwell intermingled with each other in the same area or Eastern territory, the faculties for hearing confessions duly and without restriction given to priests of any rite by their own hierarchs extend to the whole territory of him who grants them and also to the places and faithful of any other rite in the same territory, unless the hierarch of the place has expressly excluded this for places of his rite.
