Even though various proposals were put forward which enjoyed broad support in Parliament and among the national parliaments and would have made this requirement a little more flexible as regards the revision of the provisions of Part III (which are quite detailed and many of which are of questionable constitutional value) while complying with the fundamental principle that any further increase in the Union's competences would need to be unanimously approved by the Member States.
Dažādi priekšlikumi, kurus atbalstīja Parlaments un dalībvalstu parlamenti, būtu varējuši padarīt šo prasību nedaudz elastīgaku attiecībā uz noteikumu pārskatīšanu III daļā (kas ir ļoti detalizēti un daudzi no kuriem ir apšaubāmas konstitucionālas vērtības), kaut tie atbalsta pamatprincipu, ka turpmāko Savienības pilnvaru palielināšanu dalībvalstīm ir jāapstiprina ar vienbalsīgu lēmumu.
