Key legal question
Whether the claimant proved onset of work incapacity during insured employment under Art. 23 BVG
Extracted holding
The claimant did not establish that the incapacity leading to invalidity began during the insured period with the respondent pension fund.
Extracted reasoning
The records and circumstances did not make it more likely than not that a relevant functional loss appeared while employed by the municipal utility; full salary, no sickness absences, and a good work certificate supported the opposite conclusion.
