Key legal question
Whether the claimant had to reimburse CHF 96,954 in undue occupational pension benefits.
Extracted holding
Yes. The benefits were paid unduly because the insured's disability had improved during the relevant period.
Extracted reasoning
The court upheld the lower court's finding that the insured's invalidity rate had progressively improved; the fact that the disability insurer did not retroactively withdraw its pension did not affect the undue nature of the payments.
