A more thorough explanation:

REGIO ASSENSU

Regio assensu is a Latin term used in Ecclesiastical law. It refers to a writ that a sovereign issues to give their approval to the election of a bishop.

When a bishop is elected, the church sends a request to the sovereign for their approval. If the sovereign agrees, they issue a regio assensu to confirm the election.

For example, when Pope Francis was elected as the Bishop of Rome, the Vatican sent a request to the Italian government for their approval. Once the Italian government issued a regio assensu, Pope Francis was officially recognized as the Bishop of Rome.

The examples illustrate how regio assensu is used to confirm the election of a bishop. It shows that the approval of the sovereign is necessary for the bishop to be officially recognized. The writ is an important part of the process of appointing a bishop and ensures that the appointment is legitimate.
