53 By contrast, although the aim
of Directive 2004/38 is to facilitate and strengthen the exercise
of the
primary and individual right — conferred directly on all Union citizens by the Treaty — to move and
reside freely within the territory
of the Member States (see Case C ‑ 127 / 08 Metock and Others [2008] ECR I ‑ 6241, paragraphs 82 and 59; Case C ‑ 162 / 09 Lassal [2010] ECR I ‑ 9217, paragraph 30; and Case C ‑ 434 / 09 McCarthy [2011] ECR I ‑ 3375, paragraph 28), it is also intended, as is apparent from Article 1 (a) thereof, to set
out the conditions governing the exercise
of that right (see, to that effect, McCarthy, paragraph 33, and Joined Cases C ‑ 424 / 10 and C ‑ 425 / 10 Ziolkowski and Szeja [2011] ECR I ‑ 14035, paragraphs 36 and 40), which include, where residence is desired for a period
of longer than three months, the condition laid down in Article 7 (1)(b)
of the directive that Union citizens who do not or no longer have worker status must have sufficient resources.
