Key legal question
Whether the cantonal court wrongly assessed the medical and occupational evidence and unlawfully refused a bidisciplinary expert opinion.
Extracted holding
The cantonal court could rely on the detailed medical opinions and was entitled to give them more weight than the COPAI observations; refusing further evidence did not violate the right to be heard.
Extracted reasoning
The Federal Court found no arbitrary assessment: the appellant did not show concrete clinical or diagnostic elements ignored by the lower court, and occupational observation data may be less reliable than medical expertise because it can be influenced by subjective behavior during the stage.
