Canon 1532

1. A privilege is presumed to be perpetual. 2. A privilege

ceases: (1) if it is personal, when the person to whom it has

been granted dies; (2) if it is real or local, with the complete

destruction of the thing or place; (3) when the time has elapsed, or after the completion of the number of cases for which it

was granted; (4) if through the passage of time the circumstances, in the judgment of the competent authority, change to such a

degree that the privilege becomes harmful or its use illicit.

3. A local privilege revives if the place is restored within

fifty years.
