In its judgment of 13 September 2005 in Case C-0176/03, the Court clarified the relationship between policies under the first and third pillars and the primacy of Community law over Union law (Article 47 of the Treaty on European Union) when it also acknowledged that the Community legislature was entitled to require the Member States to impose criminal penalties, where absolutely necessary, in order to ensure that Community rules were fully effective.
13. septembra lēmumā (lieta C-0176/03) Tiesa noskaidroja I un III pīlāra politikas attiecības un Kopienas tiesību prioritāti attiecībā uz Savienības tiesībām (LES 47. pants), vienlaicīgi atzīstot, ka Kopienas likumdevējiem ir tiesības prasīt no dalībvalstīm noteikt kriminālsodus tad, kad tas ir nepieciešams, lai nodrošinātu Kopienas standartu ievērošanu.
