Arizona Laws 48-3047. Mistake in marking ballot
A. If when the inspector announces the name of the voter tendering him a ballot and the number of votes to which he is entitled as indicated on the ballot, it is found that the number of votes does not correspond with the number of votes to which the voter is entitled as shown by the election register, the ballot shall not be deposited in the ballot box but shall be handed to the clerk who shall destroy it without noting or making known the contents thereof. The clerk shall thereupon on demand deliver to the voter a new ballot, properly indicating the number of votes to which he is entitled.
B. If the voter in marking his ballot accidentally or by mistake wrongly marks it, he may surrender it to the clerk who shall give him a new ballot properly marked with the number of votes to which he is entitled, and destroy the old one without noting or making its contents known.
