Kernrechtsfrage
Whether the federal appeal against the cantonal interlocutory decision was admissible under Art. 93 BGG.
Extrahierter Entscheid
The appellant failed to show any irreparable harm; the appeal was therefore inadmissible.
Extrahierte Begründung
For interlocutory decisions not concerning jurisdiction or recusal, federal appeal requires irreparable harm or immediate final decision. The burden to show admissibility lies with the appellant, and he did not demonstrate such harm.
