(51)Since the objective of this Directive, namely to contribute to the proper functioning of the internal market and to the achievement of a high and as uniform as possible level of consumer protection, cannot be sufficiently achieved by the Member States, but can rather, by reason of its scale, be better achieved at Union level, the Union may adopt measures, in accordance with the principle of subsidiarity as set out in Article 5 of the Treaty on European Union. In accordance with the principle of proportionality, as set out in that Article, this Directive does not go beyond what is necessary in order to achieve that objective.
