16 CFR § 2.4 - Investigational policy.

Consistent with obtaining the information it needs for investigations, including documentary material, the Commission encourages the just and speedy resolution of investigations. The Commission will therefore employ compulsory process when in the public interest. The Commission encourages cooperation in its investigations. In all matters, whether involving compulsory process or voluntary requests for documents and information, the Commission expects all parties to engage in meaningful discussions with staff to prevent confusion or misunderstandings regarding the nature and scope of the information and material being sought, in light of the inherent value of genuinely cooperative discovery.
