§1. By virtue of office, the canon penitentiary of a cathedral church and of a collegial church has the ordinary faculty, which he cannot delegate to others, of absolving in the sacramental forum outsiders within the diocese and members of the diocese even outside the territory of the diocese from undeclared latae sentential censures not reserved to the Apostolic See.
§2. Where there is no chapter, the diocesan bishop is to appoint a priest to fulfill the same function.
