Questione giuridica chiave
Whether the insured showed a relevant worsening of health during the revision period justifying an increase to a full disability pension.
Decisione estratta
No legally relevant deterioration was proven; the prior three-quarter pension remained justified.
Motivazione estratta
The court relied on the MEDAS multidisciplinary report and other evidence showing no organic or psychiatric findings that would newly reduce work capacity. Diverging treating-physician opinions were mainly based on subjective reports and did not undermine the expert evidence.
