In Né quelque part (an obscure French movie), the main character, a French citizen, is entering France illegally (on a boat with illegal immigrants).
I am under the impression that a citizen cannot be refused the entrance to their country - this is apparently the case in the US (I saw a reference to the relevant law in several forums) and for France I could not find any information about that (there is plentiful for aliens).
It it illegal for a citizen to enter their own country illegally (without going through an established border entry point, without proper papers, ...)?
I would be interested from the perspective if international law, or French if such a law does not exist (or any other interesting case)
Note: I am not challenging the fact that someone is temporarily detained for the time needed to check their nationality. I am wondering if a citizen can be prosecuted (probably afterwards, after they entered the country) for entering their country illegally.
