Questão jurídica principal
Whether the cassation appeal was admissible despite the appellant's vague request and failure to identify federal-law violations.
Decisão extraída
The appeal was inadmissible because it did not adequately allege any violation of federal law and impermissibly attacked the traffic policy and factual findings.
Fundamentação extraída
A cassation appeal under the Penal Procedure Code could only be based on federal-law violations. The appellant merely repeated earlier submissions and criticized the desirability of the road sign, which is not a valid ground; traffic signs must generally be obeyed and the proper remedy is to challenge their installation through the prescribed administrative avenues.
