In this chapter, all aspects of the free movement of persons, including workers, establishment, services, and citizenship will be dealt with together, as, increasingly, case law and, in particular, the new case law concerned with citizenship, applies without distinction across all these categories and new secondary law has also brought many of the statutory rules for all categories of person in line in one place. The chapter covers the legal framework; the scope of the basic rights; the material scope of the rights; free movement of the self-employed; derogations from the free movement regimes; the wholly internal rule; and the treatment of third-country nationals.
