Key legal question
Whether the claimant was entitled to a full invalidity pension instead of a half pension.
Extracted holding
The record was insufficient to decide the pension entitlement conclusively because later medical indications suggested a potentially relevant change in health status requiring further clarification.
Extracted reasoning
The psychiatric expertise was initially convincing, but new lumbar complaints and MRI findings submitted later could not be dismissed without additional medical assessment; the case had to be remitted for updated inquiries on work capacity and, if necessary, the pension entitlement.
