Kernrechtsfrage
Whether the claimant was entitled to more than a half disability pension, in particular a full or three-quarter pension.
Extrahierter Entscheid
The claimant did not show that the factual finding of a 50% residual work capacity as a concierge was wrong; no higher pension was due.
Extrahierte Begründung
The medical file supported a residual capacity of 50% in the adapted concierge job. The appellant added no new elements capable of undermining the lower instance's factual findings or legal assessment.
