Kernrechtsfrage
Whether the appeal against the cost and compensation allocation in a remittal order is admissible immediately before the final merits decision.
Extrahierter Entscheid
The challenged cost and compensation ruling in the remittal decision is an interlocutory decision under Art. 93 BGG and causes no irreparable harm; the appeal is therefore inadmissible.
Extrahierte Begründung
The success of the appeal would not itself bring about a final merits decision. The Court reiterated that cost allocations in remittal decisions can be challenged later together with the final decision or separately after the final decision becomes final.
