Questione giuridica chiave
Whether the public-law appeal was admissible despite the subsidiary nature of the remedy
Decisione estratta
The appeal was admissible only within the constitutional grievance framework; any pure federal-law complaint was excluded from this procedure.
Motivazione estratta
The Court held that a public-law appeal lies for constitutional violations, but not for issues that belong to reform appeal review; the remedy is cassatory and subject to the subsidiarity rule.
