WHAT AN EXAMINING MAGISTRATE IS
France's juge d'instruction is an investigating judge with powers no prosecutor in the common-law world holds: compel testimony, order wiretaps, raid offices, freeze assets, and place targets under formal investigation (mise en examen) before any trial. The role dates to the Napoleonic Code of Criminal Instruction (1808).
WHY TRANSFER TO A MAGISTRATE MATTERS
Until transfer, the Paris prosecutor (parquet) runs a preliminary inquiry with limited compulsion. Once an information judiciaire opens, the magistrate can summon Musk and Yaccarino personally, demand X's internal moderation logs, and freeze French-domiciled assets. The DSA, by contrast, caps fines at 6% of global turnover but cannot reach individuals.
THE LICRA PRECEDENT
France has prosecuted platforms before. In 2000, LICRA v. Yahoo! forced Yahoo to geoblock Nazi memorabilia from French users — the first ruling that a US platform must comply with non-US law inside its borders. The doctrine that French jurisdiction follows the French user, not the server, has held for 25 years.
THE DUROV TEMPLATE
In August 2024, French magistrates arrested Telegram founder Pavel Durov on landing at Le Bourget airport, charging him personally for crimes facilitated by the platform. The doctrine: a CEO who refuses moderation cooperation can be treated as complicit. The X case extends the same theory to a US-domiciled executive.
THE LIABILITY SHIELD, EUROPEAN VERSION
The US Section 230 broadly immunizes platforms for user content. Europe's equivalent — the e-Commerce Directive's hosting safe harbor — is narrower: protection vanishes once the host has actual knowledge of illegal content and fails to act expeditiously. France's 2004 LCEN law codifies this. Child sexual abuse material is the category where the knowledge threshold is lowest and removal duties strictest.
THE EXTRADITION QUESTION
Even if magistrates indict, neither Musk nor Yaccarino can be compelled to appear from US soil — France and the US have an extradition treaty but neither extradites for offenses considered political or where free-speech defenses apply. The practical leverage is travel: an EU arrest warrant means any landing in Schengen territory risks detention, as Durov discovered.
