Key legal question
Whether the insured person had a right to an invalidity pension under the disability insurance scheme.
Extracted holding
No pension entitlement was established; the evidence made a rent-relevant impairment of earning capacity no longer appear probable.
Extracted reasoning
The surveillance material and the subsequent medical reassessments outweighed the earlier expert opinion. They showed that the insured performed physically demanding construction work over long periods, contradicting the claimed psychiatric and neuropsychological limitations.
