From the traditionalist position on international law, a new form of compact agreement, which cannot be classified as an international treaty in terms of academic framework, had long fueled much of contention in politics, international law, and constitutional law. A growing practice of compact agreement had been natural as corresponding with the global compression of international community and rising aspiration of peace regime on the international relations. The scholars of international law believe that, regardless of whether the President of the (...) United States is an internationalist or an isolationist, the enactment of international law in the 21st century will be based on more pragmatic rather than formal criteria. It is still true whether or not he is willing to accept or escape the international obligations so that we can more realistically share the powers conferred by the Constitution. On the other hand, a constitutional controversy on somewhat mushy yet sophisticated issues on the compact agreements began with the Laurence Tribe's acrimonious criticism in 1990. He argues that a procedure between Congress and the executive branch for the Clinton administration's accession to the North American Free Trade Agreement(NAFTA) is unconstitutional. His criticism pointed out that the NAFTA is unconstitutional since it is contrary to the text and structure of the Constitution. On the other hand, scholars of political science believe that, while a politics is termed as the distribution of values, the new form of compact agreement serves connecting the domestic and international politics as a living organism and must be affirmed from the standpoint of parliamentary politics. The political scientists argue on the necessity and inevitability of a new form of international agreement as pursuant to the nature of political process on informal procedures and parliamentary practices. In respect of the theoretical controversy, the paper is devoted to survey what the new form of compact agreement is, what types we can identify and explore the theoretical contest among the disciplines. As the dealings of paper attempt to touch on the core of scholarly assertions as fundamental and philosophical, the endeavor could inculcate the mind of international lawyers within and outside the government by providing a better framework to understand the specific real-world issues. The perception and rationale for the new form of international agreement should differ varying with their academic disciplines from which their thought stems from. The paper ends with implications within the grand scale of jurisprudence. (shrink)
