A vicar capitular, or in his place a lawful administrator, enjoys all the dispensing powers possessed by the bishop in virtue of his ordinary jurisdiction or of delegation of the law; according to the actual discipline he enjoys even the habitual powers which had been granted the deceased bishop for a fixed period of time or for a limited number of cases, even if the indult should have been made out in the name of the Bishop of N. Considering the actual praxis of the Holy See, the same is true of particular indults.
