On February 17, the Federal Register published a proposed rule that would amend the FAR to implement section 857 of the National Defense Authorization Act, making unallowable any “costs incurred by a contractor in connection with a Congressional investigation or inquiry into an issue that is the subject of a proceeding resulting in a disposition as described in 10 U.S.C. 2324(k)(2)” (i.e., criminal convictions, matters involving an allegation of fraud or similar misconduct, suspension and debarment, default termination). The proposed rule would also expand the applicability of section 857’s requirements beyond DoD to all agencies subject to the FAR, and, as written, is not clearly limited to the contractor that is actually the subject of the “proceeding or inquiry,” an important detail that should be addressed in contractor and industry comments submitted over the next 60 days prior to the publication of the final rule.
