Kernrechtsfrage
Whether the claimant proved a legally relevant deterioration of health justifying an increase to a whole disability pension under Art. 17 ATSG.
Extrahierter Entscheid
No legally relevant change in health or earning capacity was established; therefore no revision ground existed and the existing pension could not be increased.
Extrahierte Begründung
The Federal Court deferred to the cantonal factual findings, which were not manifestly incorrect. The medical reports did not show an objective worsening; the psychiatric reports were insufficient to prove disability, and further evidence was unnecessary in anticipatory appraisal.
