47Article 31 of Directive 2004/38 obliges the Member States to lay down, in domestic law, the measures necessary to enable Union citizens and members of their families to have access to judicial and, where appropriate, administrative redress procedures to appeal against or seek review of any decision restricting their right to move and reside freely in the Member States on the grounds of public policy, public security or public health (see, to this effect, Case C-249/11 Byankov [2012] ECR, paragraph 53). In accordance with Article 31(3), the redress procedures must include an examination of the legality of the decision, as well as of the facts and circumstances on which the proposed measure is based.
