and, if the application is approved, that person may vote the same day. The official in subdivisions (1) through (3) of this subsection to whom the application is submitted shall decide whether the applicant is eligible to vote. The applicant shall present to the official written or documentary evidence that the applicant is the person he represents himself to be. The official, if in doubt as to the right of the applicant to register, may require other evidence satisfactory to that official as to the applicant's qualifications. If the official determines that the person is eligible, the person shall be permitted to vote in the primary or election and the county board shall add the person's name to the list of registered voters. If the official denies the application, the person shall be permitted to vote a challenged ballot under the provisions of G.S. 163-88.1, and may appeal the denial to the full county board of elections. The State Board of Elections shall promulgate rules for the county boards of elections to follow in hearing appeals for denial of primary or election day applications to register.
