Questione giuridica chiave
Whether the constitutional complaint could be used to raise alleged arbitrariness in the application of federal traffic-sign rules.
Decisione estratta
To that extent, the complaint was not admissible because the alleged violations concerned federal law and had to be raised by nullity appeal.
Motivazione estratta
Where the complaint targets the application of federal provisions, constitutional review is excluded insofar as the same point can be examined in the federal nullity appeal.
