Question juridique clé
Whether X had standing to challenge the cantonal decision despite late constitution as private claimant.
Solution extraite
The cantonal appeal could be declared inadmissible because X was not directly injured by the traffic offenses and therefore lacked victim status and appeal standing.
Motifs extraits
Traffic-offense provisions primarily protect collective interests; a person suffering only material damage is not directly injured within the meaning of the CPP. The court held that the lateness of the private-claim constitution was not decisive for the result.
