Question juridique clé
Whether the appellant had standing under Art. 81 BGG to challenge the refusal to open a criminal investigation.
Solution extraite
He lacked standing because, as a merely injured party against police officers subject to public-law liability rules, he had no civil claims against them within the meaning of Art. 81 BGG.
Motifs extraits
Under cantonal liability law, the state alone is liable for damage caused by officials in the exercise of official functions, and no claim lies against the individual officials. Without civil claims, the appellant could not rely on victim standing; as a merely injured party he was not generally entitled to bring the criminal appeal.
