Six vignettes show how the four norms interlock in the concrete case. The examples cover the spectrum between petty offence and felony, between pupil-as-victim and pupil-as-perpetrator.
A, Visible bruises in PE (primary school). A PE teacher repeatedly notices bruises on the upper body of an eight-year-old; the child evades questions. Applicable: § 37 B-KJHG (well-founded suspicion of concrete endangerment of the child's welfare), in parallel notification to school management under § 53 BDG. School management examines § 78 StPO (suspicion under § 92 StGB tormenting or neglecting a minor) but in practice will frequently first let KJH build up their protective setting (§ 78 Abs 2 Z 1 StPO). Likely course: written KJH notification on the day of perception, KJH risk assessment, coordinated report.
B, Locker broken open, 14-year-old caught. A class teacher catches a pupil breaking open a locker in middle school. Damage approx. 60 euros. Applicable: § 127 StGB in conjunction with § 129 StGB burglarious theft. Chain of duties: teacher → school management (§ 53 BDG), school management examines § 78 StPO. With burglarious theft as a felony, the exception under § 78 Abs 2 Z 2 StPO regularly does not apply, as no ground extinguishing penalty lapses shortly. KJH notification under § 37 B-KJHG depending on indications of background endangerment. More on the procedure in our post on vandalism and theft by juveniles.
C, Nude image circulates in the class chat. A 15-year-old has sent a friend a self-recording; it is circulated in the class chat. Applicable: § 207a StGB pornographic depiction of minors, in the juvenile context with the privilege under paras. 5/6. Teacher → school management → § 78 StPO. In parallel: § 37 B-KJHG. Do not view or forward devices yourself ("evidence reflex"), this can itself fulfil § 207a StGB. More in our post on cyberbullying and explicit images among juveniles.
D, Repeated bullying posts against a pupil. Over several weeks systematically degrading images of a 13-year-old circulate in a school group; she withdraws. Applicable: § 107c StGB continuing harassment by means of telecommunication or a computer system, possibly § 115 StGB insult, § 283 StGB incitement to hatred. Chain of duties: § 53 BDG notification, § 78 StPO by school management, § 37 B-KJHG where there is endangerment of the victim's welfare. In-school conflict management (crisis team, school psychology) runs in parallel and does not replace the report.
E, Suspicion against a school caretaker of theft from the staff room. Repeated disappearance of wallets, evidence points to a caretaker. Applicable: § 127 StGB theft, possibly § 153 StGB breach of trust depending on key access. Chain of duties: teacher → school management (§ 53 BDG), school management → § 78 StPO. No own confrontation of the employee, no own searches. With narrowly supported suspicion school management examines the relationship between § 78 Abs 1 and Abs 2 StPO and the defamation threshold under § 297 StGB.
F, A father expresses suicidal intent and a threat against the child in a parent-teacher meeting. Very rare but documented. Acute constellation: Police 133 immediately, in parallel KJH on-call, in parallel school management. § 78 StPO is triggered subsequently by school management; § 37 B-KJHG is mandatory here, written notification follows on the same day. The teacher does not finish the conversation but ends it in a controlled manner (referring to follow-up counselling), brings in reinforcements and ensures the protection of the child (the child is not allowed to leave the building with the father until the police have provided clarity).
