我国刑法中的罪刑法定原则是排斥习惯法的。“法无明文规定不为罪、法无明文规定不处罚”是我国刑法基本的原则。然而在我国一些边疆地区少数民族习惯法,仍然存在对当地较大的约束力,其内部基本按照本地的习惯法处理本族内部的纠纷、矛盾。因此,应当通过立法允许在少数民族地区对刑法的变通适用,同时,也要适当限制习惯法的变通适用。 The legal principle of crime and penalty in our criminal law excludes customary law. “Law without the express provisions of not guilty of sin, the law no express provisions do not punish ” is the basic principle of our criminal law. However, some customary laws of ethnic minorities in some border areas of our country still have greater binding power on the ground, and their internal disputes and contradictions within their own families are basically handled in accordance with local customary law. Therefore, the law should be adopted to allow the adaptation of the criminal law to be applied in ethnic minority areas. At the same time, it is also appropriate to restrict the adaptation of customary law.
