Under the current rules for the amendment of the Treaties, the Treaties can only be amended by a new Treaty, which must be ratified by each of the Member States to enter into force.
Vastavalt praegustele lepingute muutmise eeskirjadele saab lepinguid muuta vaid uue lepinguga, mille aga peab selle jõustumiseks ratifitseerima iga liikmesriik.
