%0 Journal Article %T Le droit comme instrument de l¨¦gitimation et de r¨¦sistance ¨¤ l¡¯exercice de la violence ¨¦tatique %A Antoine M¨¦gie %J Champ P¨¦nal %D 2010 %I Champ p¨¦nal %R 10.4000/champpenal.7810 %X Cet article entend montrer la mani¨¨re dont le droit s¡¯est impos¨¦ dans la p¨¦riode post 11 septembre 2001 comme l¡¯un des principaux cadres de l¨¦gitimation et/ou de r¨¦sistance ¨¤ l¡¯exercice de la violence ¨¦tatique. Int¨¦ressant de mani¨¨re directe les r¨¦flexions relatives aux enjeux de la justification de la violence en termes de normes internationales, cette contribution se propose d¡¯analyser les dynamiques de fabrication du droit p¨¦nal grace ¨¤ l¡¯¨¦tude des mobilisations politiques et juridiques ¨¤ l¡¯origine de la formulation des proc¨¦dures judiciaires antiterroristes adopt¨¦es en Europe et en Am¨¦rique du Nord depuis 2001. This paper aims to demonstrate the central position of the Law as one of the important paradigm of legitimization and/or resistance to the monopoly of the use of violence following the events of 9/11. Through the problematic of international norms and their power of justification, we focus on the different political and judicial mobilizations that constitute the basis of the new counterterrorism procedures in Europe and North America. We also investigate the constitutional ramifications of counterterrorism policies in democracies and the judicial abuses in the prosecution of the ¡°war on terror¡± by analyzing the transnational transmission of norms and the nexus between technology, risk and human rights. The understanding of these mechanisms which define new legislations and practices gives meaning to the relationship between Law, violence and State since 2001. %U http://champpenal.revues.org/7810
