UnitedHealth Group Inc. v. Peterson

Issue: (1) Whether the U.S. Court of Appeals for the 8th Circuit erred in holding"consistent with decisions of the U.S. Court of Appeals for the 1st Circuit but in conflict with those of the U.S. Courts of Appeals for the 3rd, 5th and 7th Circuits"that under Firestone Tire & Rubber Co. v. Bruch, which imposes a highly deferential standard of judicial review to interpretations of Employee Retirement Income Security Act plans by administrators to whom the plans delegate interpretive discretion, an administrator"s determination that an ERISA plan authorizes certain remedial actions or measures is necessarily unreasonable merely because the plan is silent on the matter; and (2) whether the Firestone deference standard allows courts to reject an otherwise reasonable plan construction that is lawful under ERISA but, in the court"s view, pushes ERISA"s boundaries.
