The county auditor may contact other registered voters to request information that may resolve any discrepancies appearing in the application. All reasonable doubt shall be resolved in favor of the validity of the application. If the voter's challenge is affirmed, the county auditor shall provide the challenged voter with a copy of the petition and the decision and shall inform the voter of the right to appeal as provided in section 201.195.
