Kernrechtsfrage
Whether the cantonal remand decision was separately appealable to the Federal Supreme Court.
Extrahierter Entscheid
No separate appeal was admissible because the remand order caused no irreparable legal disadvantage to the insurer under Art. 93 BGG.
Extrahierte Begründung
A remand for further factual investigation normally does not create irreparable harm. The insurer could challenge the instructions later together with the final decision, and the questioned method of adequate-causality review would depend on the outcome of the further medical findings.
