Kernrechtsfrage
Whether the claimant was entitled to a half disability pension from 17 May 2000.
Extrahierter Entscheid
No. The Federal Court held that, on the 2000 state of affairs, the claimant's degree of invalidity was only 11%, which did not give entitlement to a pension.
Extrahierte Begründung
For an insured person active as an entrepreneur, invalidity had to be assessed by loss of earning capacity. The cantonal court wrongly relied on a purely medico-theoretical workload comparison. The correct comparison of incomes used 1998 as the pre-injury reference year and yielded only a minor loss of earnings.
