Our calculation
not costed
Age of criminal majority at 16 and repeal of the 1945 ordinance: legal rules; their cost would come through additional detention places, which the text does not give.
Current law, sources and limits of the cost schedule
Current law. Code de la justice pénale des mineurs (juvenile criminal justice code, 2021). Closed educational centres: cost of €578 per place per day in 2026 (public sector).
Horizon. full year 2032, €bn/year
Limits. Calculation: 100 × €578 × 365 days = €21m. Low value based on a UEHC (residential educational unit), high value with an occupancy rate and investment. Most of the lever (age of criminal majority, immediate trial, mitigation of responsibility) is not budgetary: cannot be costed apart from placement facilities.
- AN, rapport spécial PLF 2026, Justice, 2025-10: « En 2026, le coût d'une place par jour et par type de structure du secteur public serait le suivant : 578 euros en centre éducatif fermé (CEF), 510 euros en centre éducatif renforcé (CER) et 467 euros dans une unité éducative d'hébergement collectif (UEHC). »
How to read these amounts. These are static costs and revenues, with no feedback effect, over a full year: nothing on growth, employment or the revenue that economic activity would gain or lose. A higher net cost does not on its own make a worse policy, nor net savings a better one: each programme rests on an economic model (demand-led stimulus, lower compulsory levies, consolidation of the public accounts…) that the cost schedule does not settle. GDP itself measures a volume of activity, not well-being or the usefulness of what is produced. Economic models and feedback effects.
