Where any tax collector or chancery clerk has, or shall hereafter, by mistake or oversight, erroneously pay into the state treasury any moneys on account of ad valorem or privilege taxes, such officer may make application to the auditor for repayment of such taxes, and the auditor and attorney general shall thoroughly investigate such claim, and if found to be due, the attorney general shall so certify to the auditor, who shall draw his warrant in favor of such tax collector or chancery clerk, to be paid out of the same fund in which it was erroneously paid into the state.
