Key legal question
Whether the appeal against the cantonal remand order was admissible under Art. 93 BGG.
Extracted holding
The remand order was an independently appealable interim decision, but neither a non-reparable disadvantage nor a particularly costly evidentiary proceeding was shown.
Extracted reasoning
A remand for additional fact-finding with only a rheumatological expert opinion ordered is normally not a far-reaching evidentiary procedure. The appellant did not demonstrate exceptional circumstances.
