Thermal imaging and the fourth amendment:Kyllo v. U.S.

The Fourth Amendment protects persons from unreasonable searches and seizures. The extent to which the availability of new technology will impact this protection is an evolving area. One practice, police use of thermal imaging technology, has engendered substantial division in the courts. Recently, however, the United States Supreme Court addressed this issue in the case of Kyllo v. U.S. (2001). The Court determined that the pre-warrant use of thermal imaging machinery was a “search” under the Fourth Amendment and, thus, unconstitutional in nature. This paper traces the case development and examines the issues raised therein.     

美国《横向合并指南》的最新修订及启示

美国司法部与联邦贸易委员会于2010年8月联合发布了新版《横向合并指南》,新指南进一步淡化了结构主义色彩,打破了1992年指南所创设的五步分析法,相关市场界定的重要性也被大大降低,指南的制度设计趋向一个事实为基、更富弹性的分析框架。中国应借鉴美国的成熟经验,尽快研究制定横向合并指南,从"反竞争效果认定制度群"、"反竞争效果抗辩制度群"以及"反竞争效果补救制度群"三大方面来把握横向合并指南的内容。中国应注意平衡合并审查制度的确定性与灵活性,加强合并审查中法学与经济学的融合,并积极创建合并案件跟访制度。
