Canon 189

1. The eparchial bishop takes canonical possession of the eparchy by the enthronement itself, legitimately carried out, in

which the apostolic or patriarchal letter of canonical provision

is publicly read. 2. Upon completion of the enthronement, a

document is to be drawn up and signed by the eparchial bishop

along with the chancellor of the curia and at least two witnesses

and kept in the archives of the eparchial curia. 3. Before the

enthronement the bishop may not involve himself in the governance

of the eparchy either personally, through others, or in virtue of

any title. But if he had some office in the vacant eparchy he

can retain and exercise it.
