Questione giuridica chiave
Whether the pension sanction for failure to cooperate should be a permanent full withdrawal or only a limited reduction.
Decisione estratta
A permanent full withdrawal was not justified; under the circumstances, the cantonal court could limit the sanction to a 50% reduction for six months.
Motivazione estratta
The sanction must respect proportionality and the duration must match the continuing effect of the culpable conduct. The factual findings left open possible shared responsibility of the treating psychiatrist and did not show that the insured alone caused a continuing violation warranting a permanent withdrawal.
