MURPHY, Circuit Judge. A seizure disorder unfortunately ended Dr. Jean-Philippe Autran’s career as a top-notch research scientist with Procter & Gamble. In the ensuing years, Autran received total-disability benefits under the Procter & Gamble Health and Long-Term Disability Plan (the “Plan”). The Procter & Gamble Disability Committee (the “Committee”) later terminated these benefits after concluding that Autran no longer qualified as totally disabled within the meaning of the Plan. Autran sued to overturn the Committee’s benefits decision under the Employee Retirement Income Security Act (ERISA). Yet the Plan delegates discretionary authority to the Committee to decide benefits claims, so we must review its decision under the deferential arbitrary-and-capricious test. And the Committee had rational reasons to depart from the earlier total-disability finding. Among other new evidence, a doctor who performed many objective tests on Autran for over six hours found no basis to conclude that he suffered from a debilitating condition. We thus affirm the district court’s summary-judgment decision for the Committee.
