法律全球化是指全世界在一个共同的法律规则下生活的程度。就正面理论而言,它具有三重正当性,即自然正当、民意正当与功利正当,而从反向来看,主权国家的存在与法律本土化并不能对法律全球化的正当性构成真正的威胁。 Legal globalization refers to the extent to which the world lives under a common legal rule. As far as the positive theory is concerned, it has the threefold legitimacy that natural justification, public opinion legitimacy and utilitarianism. On the contrary, the existence of sovereign states and the localization of law can not pose a real threat to the legitimacy of legal globalization.
