Question juridique clé
Whether the federal constitutional complaint was admissible against the cantonal cost decision
Solution extraite
The decision was final at cantonal level, so the complaint was admissible only insofar as the constitutional pleading requirements were met.
Motifs extraits
The nullity action was the only cantonal remedy against a non-appealable cost decision; however, the Federal Court entered only on clearly and specifically argued constitutional grievances and rejected new or unsupported allegations.
