1. Every citizen of the Union has the right to move and reside freely within the territory of the Member States.
2. Freedom of movement and residence may be granted, in accordance with the Treaty establishing the European Community, to nationals of third countries legally resident in the territory of a Member State.
The right guaranteed by paragraph 1 is the right guaranteed by Article 20(2)(a) of the Treaty on the Functioning of the European Union (cf. also the legal base in Article 21; and the judgment of the Court of Justice of 17 September 2002, Case C-413/99 Baumbast  ECR I-7091). In accordance with Article 52(2) of the Charter, those rights are to be applied under the conditions and within the limits defined by the Treaties.
Paragraph 2 refers to the power granted to the Union by Articles 77, 78 and 79 of the Treaty on the Functioning of the European Union. Consequently, the granting of this right depends on the institutions exercising that power.
