Whether the insured showed a material deterioration justifying revision and increase of the disability pension
Decisione estratta
No material deterioration of health or earning capacity had occurred before the contested decision.
Motivazione estratta
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.
