Text

Treaties play a fundamental role in international relations. They are recognized as a  source of  international law in Article 38 of the Statute of the International Court of Justice. Therefore, the Vienna Convention on the Law of Treaties was adopted in 1969. The Vienna Convention regulates the conclusion and entry into force of treaties. Moreover, it regulates the application and interpretation of treaties as well as the amendment, invalidity and termination of treaties. 

According to Article 2 of this multilateral agreement, a 'treaty’ means an international agreement concluded between States in written form and governed by international law. Whether is is embodied in a single instrument or in two or more related instruments and whatever its particular designation. A treaty concluded between one or more States and one or more international organizations, or between international organizations, can also be referred to as a treaty. According to Article 38 of the Statute of the International Court of Justice, international conventions must be applied by the Court, when deciding disputes that are submitted to it. These conventions can be general or particular.  They establish rules expressly recognized by the contesting states. From this principle, one can conclude that international conventions are one of the principal sources of public international law.

The law of treaties is in constant motion, understood not only as locomotion, but also as motion through time and as change. Thus, kinesis and stasis, two sides of the same concept of 'motion', are the central themes of Treaties in Motion.
