The present invention is directed to a system and method for un-issuing a voting credit that has been erroneously issued to a voter in an election. The system includes an electronic poll book that is used to check-in a voter by locating the appropriate voter record and analyzing the voter record to determine whether a voting credit has been issued to the voter in the election. If a voting credit has been issued to the voter, the electronic poll book displays an indication that the voter has already voted in the election. If it is determined that the voting credit was erroneously issued to the voter, a poll worker enters an un-issue code into the poll book. The poll book verifies the validity of the un-issue code and updates the voter record so as to un-issue the voting credit. As such, the voter may vote a regular ballot in the election.
