Kernrechtsfrage
Whether the insured person is entitled to a full disability pension or only a partial pension.
Extrahierter Entscheid
The insured person is entitled to a half disability pension, not a full pension.
Extrahierte Begründung
The court confirmed a 87% hypothetical work capacity in health and 50% medical work capacity. Because the reduced workload stemmed from fragmented part-time employment, the parallel comparison of hypothetical incomes had to be maintained on both sides; no additional deduction for impairment was justified.
