Key legal question
Whether the cantonal court could demand disclosure of the number of mandates and fees paid to the expert in the context of the recusal request.
Extracted holding
That information was not relevant to the recusal assessment; repeated appointment of an expert by the insurer does not by itself establish bias.
Extracted reasoning
Only formal grounds for recusal are relevant. A physician's repeated work for a social insurer, even if it generates substantial income, does not create an appearance of bias under the applicable recusal rules.
