Questione giuridica chiave
Whether the constitutional complaint was admissible despite the availability of an appeal on questions of federal law.
Decisione estratta
The complaint could not be used to contest issues that were appealable under federal law.
Motivazione estratta
The dispute was pecuniary and exceeded the statutory threshold, so the appeal was available; under the subsidiarity rule, arguments amounting to federal-law criticism were excluded from constitutional review.
