Kernrechtsfrage
Whether the constitutional complaint was barred by subsidiarity because the same arguments could be raised by federal appeal.
Extrahierter Entscheid
The complaint was admissible only for genuine constitutional grievances; arguments amounting merely to federal-law errors were inadmissible.
Extrahierte Begründung
Because the appellants also raised arbitrariness and denial of proof, the Court dealt with the constitutional complaint first, but repeated that pure federal-law objections must be pursued by appeal, not constitutional complaint.
