Kernrechtsfrage
Whether the insured person had a disabling health impairment entitling her to an IV pension.
Extrahierter Entscheid
No; the medical evidence established no durable limitation of work capacity and therefore no invalidity for IV purposes.
Extrahierte Begründung
The cantonal findings based on the expert report were binding absent manifest error. The alleged accident causation was irrelevant for disability insurance, and the expert report had sufficient probative value despite the absence of a rheumatologist and separate neurological examinations.
