Question juridique clé
Whether the complaint in public law matters was admissible against the cantonal decision on tax collection and solidarity liability.
Solution extraite
The complaint was admissible; the matter concerned public law, the cantonal decision was final for tax collection, and the transitional federal rules allowed direct access to the Federal Court.
Motifs extraits
A challenge to the application of cantonal tax law on federal constitutional grounds does not preclude the ordinary public-law complaint; the cantonal tax authority acted as last instance in collection matters.
