Kernrechtsfrage
Whether the appeal against the cantonal interlocutory decision on the claimant's active standing was admissible under Art. 93 LTF.
Extrahierter Entscheid
The appeal was inadmissible because the appellant failed to show either irreparable harm or that immediate admission would avoid lengthy and costly evidence proceedings.
Extrahierte Begründung
The contested decision was interlocutory, not final, and not within Art. 92 LTF. Under Art. 93 LTF, the appellant had to demonstrate one of the two admissibility grounds, but did not do so.
