Question juridique clé
Whether the complainant had standing to challenge the dismissal of the criminal case under Art. 81 BGG
Solution extraite
He lacked standing on the merits because any claim would lie in public law against the municipality/canton, not as private civil claims against the teacher.
Motifs extraits
The alleged liability arose under Graubünden state liability law; direct civil claims against the employee were excluded, so the complainant had no civil claims capable of being asserted adhesively in criminal proceedings.
