Kernrechtsfrage
Whether the disability pension could be revoked under Art. 17 ATSG due to improved health and earning capacity.
Extrahierter Entscheid
The improvement in the claimant's condition and work capacity was established; the pension revocation was lawful.
Extrahierte Begründung
The Federal Court accepted the cantonal court's reliance on the comprehensive MEDAS expert report. The criticisms against the report did not show arbitrariness or objective defects, and the treating doctor's contrary view could not outweigh the neutral administrative expertise. Reactive psychosocial difficulties were not disabling within the meaning of social insurance law.
