Key legal question
Whether the insured is entitled to an invalidity pension
Extracted holding
The pension entitlement cannot yet be finally decided because the psychiatric findings are insufficiently clarified; the case must be returned for further investigation and a new decision.
Extracted reasoning
Although the insured is limited in his former heavy work and has a diagnosed somatoform pain disorder, the file contains unresolved contradictions on whether a significant psychiatric comorbidity exists. The lower court therefore established the facts incompletely by refusing further evidence.
