Questione giuridica chiave
Whether the insured was entitled to more than a quarter invalidity pension from 1 October 2004.
Decisione estratta
Yes. The proven work capacity was 50%, leading to an invalidity degree of 55% and thus entitlement to a half pension.
Motivazione estratta
The cantonal court could rely on the psychiatric expert opinion, which assessed the overall impact of the combined somatic and psychiatric complaints. The contrary RAD opinions lacked a specialist psychiatric basis and ignored these interactions.
