Canon 215

1. A coadjutor bishop takes the place of the absent or impeded

eparchial bishop; he must be appointed protosyncellus; the

eparchial bishop must commit to him, before others, those things

which by law require a special mandate. 2. Without prejudice

to the prescription of 1, the eparchial bishop is to appoint the

auxiliary bishop as protosyncellus. However, if there are several, he is to appoint one of them protosyncellus and the others

as syncelli. 3. The eparchial bishop is to consult the auxiliary bishop before others in considering matters of great importance, especially those of a pastoral nature. 4. The coadjutor bishop and the auxiliary bishop, who are called to share in

the concerns of the eparchial bishop, are to exercise their office so that they act in unanimous agreement with him in all

matters.
