The canon repeats a well-known norm preventing transfers of clerics between the dioceses without the consent of their former bishops. It notes a specific possibility of "promotion" of a cleric, meaning that e.g. a deacon of one diocese might have been ordained as a presbyter in another (without the proper permission). This is confirmed by Canon 54 of the Carthage Register, which deals with the case of a certain Iulianus, ordained as a lector by one bishop, and as a deacon by another (against whom the former complained).
