Kernrechtsfrage
Whether the appeal against the cantonal court's cost allocation in a remand judgment is admissible under Art. 93 BGG.
Extrahierter Entscheid
The complaint is inadmissible because the challenged cost ruling in a remand decision is itself an interlocutory decision and does not cause irreparable harm.
Extrahierte Begründung
A ruling on court costs and party compensation in a remand judgment can be challenged later together with the final decision or separately after the final decision becomes final. The second condition of Art. 93(1) BGG is therefore not met.
