Canon 204

1. The eparchial bishop, even if he has a coadjutor or auxiliary bishop, is bound by the obligation of residing in his own

eparchy. 2. In addition to those obligations which require a

legitimate absence from his own eparchy, the bishop can be absent

for a just cause for not more than one continual or interrupted

month, so long as the precaution is taken that the eparchy not

suffer harm from his absence. 3. The eparchial bishop, except

for some grave cause, must not be absent from his eparchy on days

of special solemnity established by particular law according to

the tradition of his own Church sui iuris. 4. If an eparchial

bishop exercising his authority within the territorial boundaries

of the patriarchal Church has been unlawfully absent beyond six

months from the eparchy entrusted to him, the patriarch is immediately to defer the matter to the Roman Pontiff. In other cases

this is to be done by the metropolitan or, if the metropolitan

himself has been unlawfully absent, by the eparchial bishop senior in episcopal ordination and subject to that same metropolitan.
