28 C.F.R. § 80.10
In any action brought under the applicable provisions of 15 U.S.C. 78dd-1 and 78dd-2 , there shall be a rebuttable presumption that a requestor's conduct, which is specified in a request, and for which the Attorney General has issued an opinion that such conduct is in conformity with the Department's present enforcement policy, is in compliance with those provisions of the FCPA. Such a presumption may be rebutted by a preponderance of the evidence. In considering the presumption, a court, in accordance with the statute, shall weigh all relevant factors, including but not limited to whether information submitted to the Attorney General was accurate and complete and whether the activity was within the scope of the conduct specified in any request received by the Attorney General.
