Questão jurídica principal
Whether the constitutional complaint could be used to raise alleged arbitrariness in the application of federal traffic-sign rules.
Decisão extraída
To that extent, the complaint was not admissible because the alleged violations concerned federal law and had to be raised by nullity appeal.
Fundamentação extraída
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.
