Kernrechtsfrage
Whether the cantonal return decision's partial legal-cost award could be separately challenged before the Federal Supreme Court after the final decision.
Extrahierter Entscheid
The cost allocation in the return decision was only reviewable together with the later final decision; the appeal was admissible.
Extrahierte Begründung
A return decision on the merits and its cost order are interlocutory in principle, but the cost order becomes part of the final decision and may then be appealed even if the merits are no longer contested.
