Questão jurídica principal
Whether the complainant had standing to appeal the dismissal of the contravention proceedings.
Decisão extraída
A mere denouncer who is neither injured nor a private complainant has no standing to appeal the dismissal.
Fundamentação extraída
Only parties may appeal a dismissal. Under the CPP, a denouncer without direct harm has only a right to be informed of the outcome of the report, not party status or appellate standing.
