Section 82. Auditor's Notice to Accountable Officer of Balance Shown upon Settlement. —

The auditor concerned shall, at convenient intervals, send a written notice under a certificate of settlement to each officer whose accounts have been audited and settled in whole or in part by him, stating the balances found due thereon and certified, and the charges or differences arising from the settlement by reason of disallowances, charges, or suspensions. The certificate shall be properly itemized and shall state the reasons for disallowance, charge, or suspension of credit. A charge of suspension which is not satisfactorily explained within ninety days after receipt of the certificate or notice by the accountable officer concerned shall become a disallowance, unless the Commission or auditor concerned shall, in writing and for good cause shown, extend the time for answer beyond ninety days.
