Kernrechtsfrage
Whether the appeal against the cantonal remand decision was admissible under Art. 93 BGG.
Extrahierter Entscheid
The remand order was an independently appealable interim decision, but neither an irreparable legal disadvantage nor a qualifying need to avoid extensive evidence proceedings was shown.
Extrahierte Begründung
Additional medical clarification ordered on remand could still be challenged with the final decision; the evidence measures were not unusually broad or costly.
