Question juridique clé
Whether the appeal against the order to obtain an interdisciplinary medical expert opinion was admissible as a separate appeal.
Solution extraite
The cantonal decision was an interim decision; it is separately appealable only if it concerns the formal recusal of an expert.
Motifs extraits
Under Arts. 92 and 93 BGG, medical-expertise orders are not independently challengeable unless a formal ground for recusal of the expert is alleged. Bundesgericht reviews the legality of the order later in the final decision if necessary.
