Question juridique clé
Whether the unclear expert opinion on remaining work capacity required further factual investigation.
Solution extraite
Yes. The medical report was ambiguous as to whether the insured could work five hours per day with an additional 30% loss, or whether the residual capacity itself was reduced by about 30%. Further clarification was necessary.
Motifs extraits
Because the report allowed more than one plausible interpretation and the record was therefore incomplete, the cantonal court should have ordered additional investigations. Relying on the unclear opinion violated the duty to establish the facts fully.
