Kernrechtsfrage
Whether the cantonal court was right to order further medical and economic investigation before deciding on entitlement to an invalidity pension.
Extrahierter Entscheid
The case file was already sufficient on the medical side; no further medical instruction was needed, and the remittal was unjustified.
Extrahierte Begründung
The decisive facts were established to a satisfactory degree and the legality of the contested decision had to be assessed on the record as it stood at the opposition decision date.
