Scanning School Tablets After Bullying Reports
A junior high school in Aomori has recorded 12 bullying reports in one term, three involving anonymous SNS messages after 10 p.m. The board proposes software that scans school-issued tablet accounts for keywords and flags messages to a teacher. Cost 1.8 million yen per year; field tests in other districts flagged 90 harmless messages for every one real threat. Students say the tablets are their main link to friends; parents are split. The school already has a counsellor three days a week and a paper reporting box. The proposal would operate 24 hours, including holidays, and store flagged messages for one year. The board cites Article 26 of the Constitution (right to education) and its duty to keep students safe; opponents cite Articles 13 and 21.
1. Identify the constitutional rights and interests in conflict, and explain why neither side can simply ignore the other.

Article 13 protects privacy and personal autonomy, and Article 21 protects expression and the secrecy of communications. Scanning all tablet messages and storing flagged messages for a year reaches private communication, not just classroom conduct. On the other side, Article 26 guarantees the right to education, and schools have a duty to protect students from bullying. That duty is real because three reports involved anonymous messages after 10 p.m. Neither side can be ignored: safety measures that chill private communication may themselves harm students, while a school that does nothing may fail its duty of care. The board must show necessity and proportionality, not merely cite a good purpose.
2. Apply a proportionality test: is 24-hour keyword scanning of school tablets a minimal restriction? Use the 90-to-1 figure and alternatives.

A proportionality test asks whether the measure is suitable, necessary, and balanced. Keyword scanning may be suitable because it can detect threats. But necessity is weak: the school already has a counsellor three days a week and a paper reporting box, and it could add digital-literacy lessons, targeted review after a report, or a trusted-adult contact. The 90 harmless flags for every one real threat mean many students would be wrongly suspected, creating a chilling effect and teacher workload. A 24-hour, holiday-inclusive scan with one-year storage is broad, not minimal. The policy could be redesigned to review only school-hours activity and delete non-threat data quickly.
3. Recommend a policy that the board could adopt, with two safeguards.
Read the worked answer
The board should adopt a narrow policy: scan school-issued accounts only during school hours, require human review by a teacher and counsellor within one school day, and delete non-threat flags within 30 days. Two safeguards are essential. First, no student should face discipline from a keyword flag alone; a human must confirm context. Second, the school should publish an annual audit of how many messages were flagged, how many were real threats, and how data were deleted. The board should keep the paper box and add a trusted adult, because students may not report through a system they fear. This approach serves safety while reducing the privacy restriction.
