Kernrechtsfrage
Whether the appeal against the cantonal interim cost decision was admissible immediately before the merits decision
Extrahierter Entscheid
The challenged cost order was an interim decision and could only be appealed after the final decision on the merits; no exceptional irreparable harm was substantiated.
Extrahierte Begründung
A remittal decision is an interim decision, including its cost allocation. Such a cost decision is only a procedural step in the overall proceedings and is later challengeable together with or after the final merits decision. The appellant did not allege special grounds justifying immediate review.
