Key legal question
Whether the cost and compensation allocation in a remand judgment is separately appealable under Art. 93 BGG.
Extracted holding
The cost and compensation ruling in a remand order is also an interim decision and may normally be challenged only together with the final decision; no irreparable prejudice was shown.
Extracted reasoning
Established case law treats the cost allocation in a remand decision as an interim matter. The appellants could challenge it after the final cantonal decision without having to exhaust the whole appellate route now.
