摘要

The international treaty represents the juridical document expressing the will agreement interfered between the international public law subjects in order to create, change or annul rights and obligations in the reports between them, and which is governed by the international law. For the valid existence of the international treaties, it is necessary to accomplish basic conditions regarding the capacity of the international public law subjects to contract a treaty, the free and un-vitiated manifestation of the parties' will and the existence of a legal and accomplishable object of the treaty. The nullity causes kept by the 1969 Vienna Convention regarding the treaties law refer to the consent vices and to the disrespecting of the imperative norms of international general law (ius cogens). The present article wants to accomplish an analysis of the nullity causes of the international treaties in report mainly to the stipulations of the 1969 Vienna Conventions regarding the treaties law, but also to other international documents in the matter.
