變動中的Jus Cogens--緣起、發展與定型(上)

Abstract

At meantime the era of human rights succeeding the end of World War Ⅱ, the institution and order of international society underwent dramatic transformation that obviously featured in the expansion, specialization and systemization of international organizations, for example, the United Nations and its sub-organizations such as the unification of the European Union and American and African regional organizations. In addition, the order of international laws has changed radically. Besides the interacting development among the independent systems of international environmental law, international criminal law, international economic law, that has delicately constituted both the procedural and essential rules of international law, the relation between international laws and sovereign nations has also been re-defined. Through the introduction to the concept of ”complete value of international society”, the connection between sovereignty and international law has been re-interpreted. The most innovative breakthrough was nothing but the concepts of Jus Cogens and Obligations Erga Omnes, as well as the acceptance of the philosophical reasoning behind the concepts. Thus international law has gradually diversified its appearance and, by further development of the above concepts that jointed the different fields of international law, the institution of international law has been overturned. From the aspect of substantial norm, the continuing restriction of applying the opposition rule, development of treaty reservation, succession and admission of nation, ruling of extradition treaties, restriction on national exemption, defining the serious jeopardizing act of international crime, the gradual change of the status of international soft law and the transforming of the national liability system, have attributed to revolution of the content of international law. From the aspect of the procedural norm, the expansion of common jurisdiction and the change of international/domestic lawsuit initiation, have shown great influence that closely connected international criminal law. Therefore, Jus Cogens ought to be the most important medium of the recent development of international law that revealing the combination of Jus Cogens and state responsibility law system, also further led international law to the equivalence of rights and obligations. Frankly, the Vienna Treaty Law Convention signed in 1969, was the milestone of the international law development, which positioned the Jus Cogens in the statute law. If ”power-oriented” is the characteristic of international law in 19th century, then international law after 1950s has gradually dispensed primitiveness and become ”rule-oriented”. Although 1969 could be the beginning of Jus Cognes, suspicion on carrying out this concept in international law still remains. International law scholar, Ian Sinclair, concluded opinions toward Jus Cogens that further confirmed ”Jus Cogens is still a mystery”. Some scholars even express directly that nevertheless adopting Jus Cogens has essentially attributed to the transformation of international law, yet there is worry about the application of Jus Cognes could be contradictive, and even opening the gate for some certain countries to import particular international law systems matching their ideology, thus becoming denial to a diversified international society. Even though contrary opinions toward Jus Cogens remain, from 1968 the concept has been accepted by sovereign countries and also adopted to judgments that further expand Jus Cogens, making this theory combine with other institutions of the international law rather than be confined within treaty law field. Hence, focusing on Jus Cogens and the connection as well as the change of Jus Cogens in the late 40 years, this thesis analyzes the elaboration on Jus Cogens from national practice, international justice and scholars. However, this thesis could only be able to introduce this theory briefly due to the limited length. Therefore, this thesis mainly discuss the following particular sectors of the theory of Jus Cogens: (1) the definition and development of Jus Cogens. (2) the objects regulated by Jus Cogens and the effect. (3) connections between Jus Cogens and other international law concepts newly developing trend. (4) At last, examining and looking back to dialogues made between Jus Cogens and international law.
