A Practice Note discussing the legal issues that may arise when federal agency officials communicate with non-federal entity (NFE) contractors during the different phases of a procurement action. The Federal Acquisition Regulation (FAR) directs federal agency officials on the appropriate engagement of contractors during a procurement action under FAR 15.201 and 15.306. This Note discusses the circumstances that allow a federal official to communicate with a contractor before or after the deadline for receipt of proposals, what information may be exchanged, and the remedy for curing any inappropriate communication to reduce litigation risk and uphold the integrity of the federal procurement system.
