Key legal question
Whether the appeal against the cantonal remand judgment was admissible as a challenge to an independently appealable expert-recusal issue.
Extracted holding
The judgment was only appealable to the extent it concerned the recusal of the expert; otherwise it was an interim decision.
Extracted reasoning
Recusal questions concerning a medical expert are separately appealable under Art. 92 BGG; the rest of the remand decision remains an interim ruling under Art. 93 BGG.
