Questione giuridica chiave
Whether the insured person's psychiatric aggravation entitled him to a full disability pension before 2006.
Decisione estratta
A full disability pension was due, but the effective start date could not be fixed before the month in which the revision procedure had been initiated.
Motivazione estratta
The cantonal court could not rely on a post hoc warning letter to infer a prior failure to mitigate damage; however, the expert evidence established a 70% overall incapacity. Under Art. 88bis al. 1 RAI, the increase could take effect only from the earliest permissible month after the revision request, namely 2003-11-01.
