(70)Since the objective of this Directive, namely to contribute to the functioning of the internal market by tackling in a consistent manner contract law-related obstacles for the cross-border sales of goods in the Union, cannot be sufficiently achieved by the Member States, due to the fact that each Member State individually is not in a position to tackle the existing fragmented legal framework by ensuring the coherence of its law with the laws of other Member States, but can rather, by removing the principal contract law-related obstacles through full harmonisation, 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 this objective.
