Kernrechtsfrage
Whether the insured person was entitled to at least a half invalidity pension instead of a quarter pension.
Extrahierter Entscheid
The medical and economic assessment supported only a 43% invalidity degree; the threshold for a half pension was not reached.
Extrahierte Begründung
The court accepted the lower court's assessment that the claimant remained 60% capable of work. The income comparison based on the Swiss wage structure produced no invalidity degree of at least 50%, even with a possible deduction.
