Key legal question
Whether the claimant is entitled to an invalidity pension despite a diagnosed somatoform pain disorder.
Extracted holding
The file did not permit a final assessment; the assumption that full work capacity existed in every activity was insufficiently founded.
Extracted reasoning
The psychiatric reports contained indications of a chronified pain condition, personality-related overstrain, and reduced concentration, yet no expert had addressed whether pain could reasonably be overcome by willpower under the relevant criteria.
