Question juridique clé
Whether the criminal complaint appeal was admissible for lack of civil-claims standing under Art. 81 LTF.
Solution extraite
The appellant did not show that the challenged decision could affect any civil claims; therefore he lacked standing.
Motifs extraits
A private complainant must explain what civil claims are affected and how the decision could influence them. The appellant made no such showing, and the alleged school-absence issue falls under administrative law, not civil claims.
