Det bør yderligere overvejes, at en ændring af retsgrundlaget vil hindre medlemsstaterne i at have fleksibilitet til at træffe indeslutnings- og kontrolforanstaltninger, der går ud over dem i direktivet, hvilket de på nuværende tidspunkt kan gøre, fordi medlemsstaterne i deres nationale lovgivning nu kan gå ud over de standarder, der er fastlagt i direktivet.
An additional consideration is that the change of legal base would restrict Member States from having the flexibility to take containment and control measures going beyond those in the directives which at present they can do, because currently Member States can go beyond the standards set out in the directive in their national legislation.
