Key legal question
When did the waiting period and thus entitlement to a disability pension begin?
Extracted holding
The finding that the exact onset of incapacity could not be determined and that the relevant deterioration was established no earlier than 2009 was not clearly wrong.
Extracted reasoning
The court deferred to the cantonal court's assessment of the psychiatric evidence. Retrospective psychiatric evaluations allow a margin of interpretation; the expert himself stated that an exact retroactive date could not be fixed. The insured had in fact worked 70% until end 2008, which supported the cantonal finding.
