Since the objective of this Regulation, namely the creation of a system for the comparison of biometric data to assist the implementation of Union asylum and migration policy, cannot, by its very nature, be sufficiently achieved by the Member States, but can rather 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 (TEU). In accordance with the principle of proportionality, as set out in that Article, this Regulation does not go beyond what is necessary in order to achieve that objective.
