Questione giuridica chiave
Whether the pension reduction could be justified by revision under Art. 17 LPGA due to a relevant change in health or work capacity.
Decisione estratta
No relevant and proven change was established; the medical record did not show a notable improvement justifying revision.
Motivazione estratta
The cantonal court’s assessment of the medical evidence was not shown to be arbitrary. The appellant merely substituted its own view for the lower court’s appraisal, which is insufficient under the Federal Supreme Court’s limited review.
