Question juridique clé
Whether the federal appeal was admissible despite being labeled as a subsidiary constitutional complaint and directed against an interlocutory cantonal decision.
Solution extraite
The appeal was treated as an appeal in public law and admitted exceptionally because the wrong legal remedy instruction would otherwise create a procedural dead end.
Motifs extraits
The challenged decision was an interlocutory decision in principle not immediately appealable, but the misdirection in the remedy notice, the later issuance of the final contribution decision, and the need to avoid pointless procedural delay justified review.
