Key legal question
Whether the appeal against the party-costs allocation in a remand decision was admissible before the Federal Supreme Court.
Extracted holding
The challenged costs and compensation ruling in the remand decision was itself an interlocutory decision; no irreparable harm was shown.
Extracted reasoning
Under settled case law, costs and compensation determinations contained in a remand decision are separately challengeable only together with the final decision or after it becomes final. The second branch of Art. 93(1) BGG was irrelevant, and the first branch was not met.
