This would seem to imply that a French public servant who obeys an "obviously illegal" order is both knowingly (it's obvious) and willfully (there's no requirement to obey) breaking the law.
What are the penalties for that?
The term used in French isn't quite as strong as "obviously", it's "manifestement illegal". See Wordreference: https://www.wordreference.com/fren/manifestement . Apparently English has "manifestly" but I never heard it so unsure if it's a good translation.
> What are the penalties for that?
I had to look it up, it seems you're considered complicit in whatever the order was about. Basically the "Nuremberg defense" AKA "I just followed orders" is void here.
"Manifestly" seems fine as a translation, though in English I would consider it to be about equally as strong as "obvious", or possibly stronger because it's an unusual, formal-sounding word that might suggest you're trying to sound emphatic.

If they choose to follow orders they know are illegal they can be personally liable.
