Consent is one of the fundamental principles in the realm of treaties. Article 36 of the Vienna Convention on the Law of Treaties deals with the conditions under which any State may be entitled to invoke a right under a treaty to which it is not a member. Providing right for the third State should be examined in the light of essential criterion of consent in conventional international law. Therefore this crux of the problem is whether the right of the third State is derived from the original treaty or from that States’ acceptance of the right or in other words, is the conclusion of a treaty among the third State and the original treaty parties. Given the crucial role of treaties in the international law, the understanding of legal dimensions of this entity is significant in the realm of conventional law and the Vienna Convention. In relation to this issue, although there are a few case laws, the trace could be seen in the annexed opinion of judges to PCIJ and ICJ decisions. This article analyzes the right for third law entities and explains items that are prima facie placed in this realm, but they are not actually instances of article 36 of the Vienna Convention.
