I am reading a bit more about this. In a similar case, where Fair Trials intervened, they made this submission: https://www.fairtrials.org/app/uploads/2022/03/FT-interventi... . In the submission there are these sentences:

> Law enforcement authorities may compel suspects to provide the passcode to their mobile device under threat of a legal sanction pursuant to Article 434-15-2 paragraph 1 of the French Criminal Code, [...]. The request must be sanctioned by a judicial authority.

What is this sanction by judicial authority? A court order? Can it be appealed against? Can i get a lawyer participate in the hearing for the sanction?
