Restrictions on the right to move and reside freely in France imposed on foreign nationals whose situation is governed by this book may only be justified by behaviour which constitutes, from the point of view of public order and public safety, a real, current and sufficiently serious threat to a fundamental interest of society.
The same applies when the foreign national whose situation is governed by this book has been subject to a penalty of inadmissibility, a deportation order, a ban on movement within French territory or an administrative ban on entry.
