The main purpose of the present submission relates to the matter of the postulation regulated by the legal disposition expressed in canons 180 e 181 CIC/83. The main emphasis is not placed on the correct application of the canon law, in the case concerning the dispensation granted to who is ineligible to the canonical office or other assignment. Instead, the Author tries to highlight the meaning and importance that must be given to the discernment undertaken by the collegial Authority in the case of election. The article presents the certain conditions required from the candidate and, at the same time, supplies these criteria, which usually are considered by the Congregation of Institutes of Consecrated Life and Societies of Apostolic Life in the matter of admission of the postulation.
