Administrative agencies are bound by regulations promulgated by the Attorney General (28 C.F.R. §§ 43.1 to 43.4) and generally will prevail upon the insured person to assert the government's claim in his/her own name for the use and benefit of the United States. 42 U.S.C. § 2651(b)(1) authorizes the government to intervene in the insured person's tort suit as of absolute right. If intervention is necessary, the injured person can normally be counted on to establish the defendant's basic tort liability. Intervention should be utilized as a measure of last resort only if private counsel do not cooperate with the agency to protect our right to participate in agency recovery.
