1° They no longer justify any right to residency as provided for by articles L. 232-1, L. 233-1, L. 233-2 or L. 233-3;
2° Their personal behaviour constitutes, from the point of view of public order or public safety, a real, current and sufficiently serious threat to a fundamental interest of society;
3° Their residence constitutes an abuse of rights.
