Question juridique clé
Whether the appeal was admissible against an interlocutory order on costs and compensation
Solution extraite
The order was an interlocutory decision challengeable only under Art. 93 BGG, and neither an irreparable harm nor an immediately final decision was shown.
Motifs extraits
The appellant failed to demonstrate that upholding the appeal would immediately lead to a final decision and save significant time and expense. A costs/compensation allocation does not cause irreparable harm because it can later be challenged with the appeal against the final decision.
