Questão jurídica principal
Whether the appeal was admissible against the cantonal decision concerning the appointment of a medical expert centre.
Decisão extraída
The appeal was inadmissible because such decisions are not appealable to the Federal Supreme Court absent formal grounds for challenge, and no such grounds were raised.
Fundamentação extraída
The court held that the prior decision concerned an interlocutory measure on expert evidence. Under Art. 93 BGG and BGE 138 V 271, such decisions are generally not subject to appeal to the Federal Supreme Court unless formal recusal grounds are at issue. The appellant only criticized the IV office's choice procedure, which could be raised later against a final decision if relevant.
