Examine the tension between national digital-safety legislation and supranational (EU) regulatory jurisdiction over technology platforms.

Article 28 of the EU's Digital Services Act (DSA) makes minors' online safety a Union-level obligation, with the Commission enforcing against very large platforms [1]. Yet France's Bill barring under-15s from social media, cleared by both chambers on 21 July 2026 [2], shows member states legislating ahead of Brussels — exposing a structural friction between democratic urgency at home and harmonised regulation above.

Why national legislation runs ahead

• Political mandate: child mental health and screen addiction are domestic electoral issues; France's law also bans mobile phones in high schools from the 2026-27 session [2].
• First-mover demonstration: Australia's under-16 restriction, live from 10 December 2025, proved unilateral action is feasible and shifted the debate [3].
• Contagion: Spain, Greece, Austria and Germany are weighing comparable thresholds, making national law a de facto agenda-setter for the EU.

Where supranational jurisdiction bites

• Exclusive competence: obligations on TikTok, Instagram or Snapchat flow from the DSA, not national statute; France's earlier 2023 "digital majority" law was judged incompatible with EU law and never applied [2].
• Single-market logic: divergent national ages fragment a harmonised digital market and burden cross-border services.
• Sequencing conflict: the Commission's age-verification blueprint targets rollout by end-2026 [4], while France must rely on a privacy-regulator-approved system sooner.

Contested middle ground

• Constitutional review: over sixty deputies referred the French law to the Constitutional Council on 23-24 July 2026 [2] — anonymity and proportionality remain unsettled.
• Enforcement capacity: listing covered platforms and verifying age demand administrative depth no statute can supply by itself.

The tension is less a jurisdictional deadlock than a bargaining mechanism: national laws generate the political pressure that supranational rules then standardise and make enforceable. A cooperative path — common age-verification standards with member-state discretion on thresholds — best reconciles subsidiarity with the single market. India's evolving approach, requiring verifiable parental consent for children's data under the DPDP Act, 2023 [5], faces the same balance between protection, privacy and workable enforcement.
