Questão jurídica principal
Whether the appeal remained admissible despite the lack of current practical interest because the arrest had already been served.
Decisão extraída
Yes. Although the sanction had already been executed, the court waived the requirement of a current interest because the issue could recur and timely judicial review is usually impossible.
Fundamentação extraída
The situation could arise again, the court could rarely decide it in time, and clarification served the public interest.
