Questão jurídica principal
Whether the cantonal return decision's partial legal-cost award could be separately challenged before the Federal Supreme Court after the final decision.
Decisão extraída
The cost allocation in the return decision was only reviewable together with the later final decision; the appeal was admissible.
Fundamentação extraída
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.
