Questão jurídica principal
Whether the insured person was entitled to a full rather than half invalidity pension from 1 November 2003 to 4 March 2009.
Decisão extraída
The assessed invalidity degree remained below the threshold for a full pension; only a half pension was due.
Fundamentação extraída
The courts accepted a 50% performance loss in the insured's continued self-employed activity. Valid income was based on his own stated monthly income of CHF 4,500 because no reliable business accounts existed. With an invalid income based on LSE tables and a 15% deduction, the resulting invalidity degree was about 59%, which supports only a half pension.
