Question juridique clé
Whether the appeal against the cantonal costs and compensation decision was admissible as a separate appealable decision.
Solution extraite
The challenged decision was an interlocutory decision; it did not cause an irreparable harm under Art. 93(1)(a) BGG and was therefore not immediately appealable.
Motifs extraits
The allocation of costs and party compensation in an interlocutory decision can be reviewed later together with the final decision. Mere delay or expense is insufficient for immediate federal review.
