(a) The Government Accountability Office no longer requires that a certificate as to correctness and nonpayment be executed on the bills and invoices of contractors and vendors, with the exception that carriers, or other corporations, agencies, or persons furnishing transportation and accessorial services to the Government must continue to execute the certificates as provided in chapter 101 of 41 CFR part 41. Pending the eventual elimination of the contractors' and vendors' certificates from all other standard voucher forms, the certificates on such other forms need no longer be executed. However, the elimination of this requirement does not dispense with the necessity for the specific certification of facts required by certain contracts.
(b) The omission of the certificate from bills or invoices submitted for payment to Government agencies does not in any manner lessen the responsibility of contractors and vendors in complying with all statutory requirements applicable to transactions with the Government, nor will it be construed as mitigating their liability for asserting false, fictitious, or fraudulent claims against the United States, penalties for which are set forth in 18 U.S.C. 287.
