A proposed EU constitutional treaty would have helped sort out the existing problems and limitations to further enlargement, but it was put on the shelf after Dutch and French voters rejected it in separate referendums last year.
Predloženi ustavni sporazum EU mogao je pomoći u reguliranju postojećih problema i ograničenja za daljnje proširenje, ali je ostavljen po strani nakon što su ga nizozemski i francuski birači odbacili na odvojenim referendumima održanim prošle godine.
