Kernrechtsfrage
Whether the cantonal court incompletely established the insured person's ability to work because it failed to clarify morning toilet needs and practical work capacity.
Extrahierter Entscheid
Yes. The court had to investigate whether the claimant could only leave home after noon and whether a 70% capacity was actually realizable.
Extrahierte Begründung
There were sufficient indications from the file that the claimant suffered marked morning bowel problems. If she could not work before noon, the current job could not serve as the basis for the income comparison; further medical and factual clarification was required under the duty to investigate.
