Kernrechtsfrage
Whether the insured was entitled to a pension higher than the quarter pension granted by the cantonal court.
Extrahierter Entscheid
The complaint was only partially upheld: the pension entitlement had to be set on the basis of an invalidity degree of 47%, giving a quarter pension from 1 April 2001 and, if conditions were met, only a half hardship pension until 31 December 2003.
Extrahierte Begründung
The cantonal court incorrectly applied the invalid income calculation by multiplying the residual earning capacity twice. The factor for 40% working capacity in the already reduced part-time workload had to be omitted; with the corrected comparison income, the invalidity degree was 47%, not 63%.
