> a ruling by a lower court which sets a very dangerous precedent
There's no precedent of any kind being set here. Court orders have to be obeyed unless overturned, this isn't an unprecedented 2024 thing. France has a civil law legal system, not the precedent based common law legal system (like the US for example). This court set no legal precedent, it issued a ruling on this particular case.

A court, for not respecting a court order.
The legal system and law in general are almost never common sense and there's a reason it takes so much work and experience to navigate them properly. If you've done none of that work, assume you're wrong.
If you're a techie and you start hearing people insist with personal opinions on how those RAM traces should be made longer and straighter you'd wonder why they keep talking.
