Questão jurídica principal
Whether the insured showed a material deterioration justifying revision and increase of the disability pension
Decisão extraída
No material deterioration of health or earning capacity had occurred before the contested decision.
Fundamentação extraída
The medical reports supported the view that the claimant's failed job search and alcohol dependence did not establish a relevant worsening; the cantonal court's factual assessment was not shown to be clearly wrong.
