Questione giuridica chiave
Whether the claimant's condition had materially worsened in the relevant comparison period so as to justify a pension revision.
Decisione estratta
No legally relevant substantial change in health was established; the existing quarter pension remained unchanged.
Motivazione estratta
The cantonal court could rely on the earlier full probative expert report and the later psychiatric and medical reports. The claimant's submissions were largely appellatory and did not show that further multidisciplinary evidence would likely yield decisive new findings; anticipatory appraisal of evidence was permissible.
