From the opinion in Metropolitan Life Insurance v. Glenn, No. 06-923, issued today by the Supreme Court:
The Employee Retirement Income Security Act of 1974 (ERISA) permits a person denied benefits under an employee benefit plan to challenge that denial in federal court. 88 Stat. 829, as amended, 29 U. S. C. §1001 et seq.; see §1132(a)(1)(B). Often the entity that administers the plan, such as an employer or an insurance company, both determines whether an employee is eligible for benefits and pays benefits out of its own pocket. We here decide that this dual role creates a conflict of interest; that a reviewing court should consider that conflict as a factor in determining whether the plan administrator has abused its discretion in denying benefits; and that the significance of the factor will depend upon the circumstances of the particular case. See Firestone Tire & Rubber Co. v. Bruch, 489 U. S. 101, 115 (1989).
