Key legal question
Whether the cantonal court could rely on the MEDAS psychiatric assessment to confirm a half invalidity pension.
Extracted holding
The MEDAS report was not a sufficient basis for findings on the insured person's psychiatric condition and resulting work capacity.
Extracted reasoning
The psychiatric diagnoses and their interaction were insufficiently explained; the criteria for a somatoform pain-like disorder were not properly applied; several relevant factors supporting incapacity were not established.
