Questão jurídica principal
Whether the insured had a right to an invalidity pension despite a somatoform pain disorder.
Decisão extraída
The case could not be finally decided because the factual findings on the alternative criteria for overcoming a somatoform pain disorder were incomplete.
Fundamentação extraída
A severe psychical comorbidity was rightly denied, but the cantonal court failed to make decisive findings on the additional criteria developed in case law, such as chronic physical comorbidities, treatment resistance, and primary gain.
