Questione giuridica chiave
Whether the insured person was entitled to an invalidity pension and from when
Decisione estratta
The insured person was entitled to a quarter pension from 1 May 2004.
Motivazione estratta
The cantonal court correctly parallelized the income comparison because the insured had earned a clearly below-average wage for invalidity-external reasons. After a 30% downward adjustment of the statistical invalid income and a further 10% leidensbedingter Abzug, the resulting invalidity degree was 42%, sufficient for a quarter pension.
