Since the objectives of this Directive cannot be sufficiently achieved by the Member States but can rather, by reason of the need for Union-wide harmonised rules, 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).
Ós rud é nach féidir leis na Ballstáit cuspóirí na Treorach seo a ghnóthú go leordhóthanach agus, de bharr an ghá atá le rialacha comhchuibhithe uile-Aontais, gur fearr is féidir iad a ghnóthú ar leibhéal an Aontais, féadfaidh an tAontas bearta a ghlacadh, i gcomhréir le prionsabal na coimhdeachta, mar a leagtar amach in Airteagal 5 den Chonradh ar an Aontas Eorpach (CAE).
