The Department of Defense has finalized, without change, an interim rule (¶70,016.606, DFARS Case 2010-D02) that amended the Defense Federal Acquisition Regulation Supplement to implement section 1038 of the National Defense Authorization Act for Fiscal Year 2010 (PL 111-84), which prohibits contractor personnel from interrogating detainees under the control of DoD. The interim rule added DFARS 237.173, Prohibition on interrogation of detainees by contractor personnel, which consists of five subsections. Under new DFARS 237.173-3, Policy, no detainee may be interrogated by contractor personnel. However, contractor personnel with proper training and security clearances may be used as linguists, interpreters, report writers, and information technology technicians, and in ancillary positions such as trainers of and advisors to interrogators, if the personnel meet the criteria provided by DoD Instruction 1100.22, Policy and Procedures for Determining Workforce Mix (http://www.dtic.mil/whs/directives/corres/pdf/110022p.pdf), DoD Directive 2310.01E, The Department of Defense Detainee Program (http://www.dtic.mil/whs/directives/corres/pdf/231001p.pdf), and DoD Directive 3115.09, DoD Intelligence Interrogations, Detainee Debriefings, and Tactical Questioning (http://www.dtic.mil/whs/directives/corres/pdf/311509p.pdf).
