Key legal question
Whether the appeal against the cantonal order was admissible despite being directed against an interim decision
Extracted holding
The appeal was admissible because the challenged order could cause an irreparable legal disadvantage within the meaning of Art. 93(1)(a) BGG.
Extracted reasoning
If the lower court order stood, the insurer would have to issue a substantive objection decision and could no longer challenge the admissibility issue later; this exposed it to a disadvantage not repairable by a later appeal.
