The patron cannot present his own name. Co-patrons may, however, present one of their own number. If through no fault of the patron, the name of an ineligible person is presented, he is granted a certain time of grace to make a new presentation. If, however, an ineligible person has been knowingly presented, the spiritual patron loses for the time being the right of presentation, but the lay patron, so long as the first interval allowed for presentation has not expired, may make an after-presentation. Thus the presentation of the spiritual patron is treated more after the manner of the episcopal collation. On that account the spiritual patron is not permitted an after-presentation or a variation in choice, which is permitted the lay patron, after which the bishop has the choice between the several names presented.
