Week 05: Amendment and Modification of Treaties, Invalidity of Treaties, termination and withdraw of treaties

     Although amendment and modification of treaties are two processes share a common aim which is an alteration or revision of a treaty, they are two separate processes accomplished by different manners and subject to different rules and conditions.  Amendment relates to a formal alteration or revision of certain treaty provisions or the treaty as a whole, affecting all the parties to that treaty.  Modification relates to an alteration or revision of certain treaty provisions as between particular parties only.  Thus the 1969 Vienna Convention on the Law of Treaties deals with these two processes in separate articles.
