"Catholic Church

In the Catholic Church, a bishop's resignation is often accepted by the Holy See nunc pro tunc, which means it is tentatively accepted, but the Pope needs some time to locate and appoint a replacement for that diocese. The announcement of the new appointment is usually accompanied by actual acceptance of the outgoing bishop's resignation."
