Questão jurídica principal
Whether the requirements for revising the disability pension under Art. 17 LPGA were met because the insured's health had materially improved.
Decisão extraída
The insured's psychiatric capacity changed from 35% to 50%, which constituted a notable and lasting improvement justifying revision and reduction of the pension.
Fundamentação extraída
The Federal Court upheld the cantonal court's reliance on the CEMED expertise. The later treating-physician reports did not undermine that expertise because they related to later facts or did not convincingly contradict the expert assessment. The improvement was durable and no imminent worsening was established under Art. 88a RAI.
