Kernrechtsfrage
Whether the appeal against the interlocutory order was admissible under Art. 93(1)(a) LTF due to irreparable harm.
Extrahierter Entscheid
No legally relevant irreparable harm was shown or made plausible; any alleged procedural defect could still be raised against a final judgment.
Extrahierte Begründung
The claimed prejudice from the appellate court deciding on the file without further submissions was not shown to be juridical and irreversible. A later appeal against an unfavorable final decision remained available.
