Kernrechtsfrage
Whether the claimant was entitled to a full disability pension from 1 April 2004.
Extrahierter Entscheid
No full pension was due from 1 April 2004; the evidence supported only a later entitlement to a half pension.
Extrahierte Begründung
The medical record showed full incapacity in the former occupation, but residual capacity in adapted work. The initial 100% disability was not established.
