The council of Carthage in 407 asked the emperor to allow the churches to appoint defensores ecclesiae through whom the petitions to the governors of the province could be made, because until then such petitions must have been made through coronati, that is provincial priests of the imperial cult. In the present law, the emperors agreed to do that but under restriction that the defensores should act only in strictly ecclesiastical cases; any other privileges of the coronati should not be diminished.
