24Article 9 of the Directive states, firstly, that Member States are to ensure that judicial and/or administrative procedures for the enforcement of obligations under the Directive are available to all persons who consider themselves wronged by failure to apply the principle of equal treatment to them and, secondly, that those obligations of the Member States are without prejudice to national rules relating to time-limits for bringing actions as regards that principle. It follows from that wording that the question of time-limits for initiating a procedure for the enforcement of obligations under the Directive is not governed by European Union law.
