We said earlier—perhaps you missed it—that we agreed with removing the day and month of the person's date of birth, if necessary; we feel, however, that the person's year of birth should remain to help deputy returning officers and officials determine whether the person before them is 80 years old or 20 years old. And, if there is any doubt, they can ask the elector further questions to confirm their identity.
