Several national Parliaments argue that the Commission has failed to comply with the requirement of Article 5 of Protocol No 2 to the Treaty, which provides that drafts legislative acts shall be justified with regards to the principles of subsidiarity and proportionality, considering that the justification in the explanatory memorandum of the proposal is too succinct.
Nekoliko nacionalnih parlamenata tvrdi da se Komisija nije pridržavala zahtjeva iz članka 5. Protokola br. 2 Ugovora kojim se predviđa da nacrti zakonodavnih akata moraju biti opravdani s obzirom na načela supsidijarnosti i proporcionalnosti, i smatraju da opravdanje iz obrazloženja koje je izneseno u prijedlogu nije dovoljno detaljno.
