Question juridique clé
Whether the complaint against the cantonal allocation of costs and compensation in a remand decision was admissible before the Federal Supreme Court.
Solution extraite
The challenge was inadmissible because the costs and compensation ruling in a remand decision is itself an interim decision and no irreparable harm was shown.
Motifs extraits
Under Art. 93 BGG, such ancillary cost rulings can be reviewed later together with the final decision or separately after finality; the second route under Art. 93(1)(b) BGG was irrelevant.
