中文摘要正当防卫是世界各国刑法的一项重要法律制度,是法律给予公民同违法犯罪行为作斗争的一种重要权利和手段。我国 1997 刑法第 20 条在规定正当防卫的同时,也规定了防卫过当行为应当负刑事责任,但对该条款的理解学界存在争议。由于立法过于简略,没有对“明显超过必要限度”、“重大损害”和防卫主观方面作出明确的界定,造成了正当防卫在理论和实践中都存在争论,特别是罪与非罪,导致在司法实践中不容易操作。本文通过对其他国家防卫过当制度的比较讨论与借鉴,提出完善我国防卫过当制度的建议,从而使国家、公共利益、本人或者他人的人身、财产和其他权利免受正在进行的不法侵害,更好地保护人权。关键词:正当防卫;防卫过当;重大损害AbstractSelf-defense is the world an important legal system of criminal law, is give to citizens by law to combat criminal acts of an important right and means.
