Questione giuridica chiave
Whether the start of the disability pension had to be set retroactively to 1 March 2004 instead of 1 May 2005.
Decisione estratta
No. The insured person failed to prove continuous full incapacity before 5 May 2004; the cantonal finding on the start of the waiting period stood.
Motivazione estratta
Retrospective medical opinions were insufficient without contemporaneous medical documentation. The evidence showed no reliably proven complete incapacity during the relevant period, and a psychiatric diagnosis alone did not establish reduced work capacity.
