我国是一个统一的多民族国家,有五十五个少数民族,因而研究并解决少数民族习惯法与法律冲突问题是非常迫切的。允许民族自治地方根据自己的当地特色情况,在不违背宪法和法律基本原则和基本精神的前提下制定变通或者补充的规定的做法是非常正确和必要的。本文试着从少数民族习惯法与法律发生冲突的角度,研究民族自治地方制定变通规定的限度问题,以及究竟在什么样的原则下进行变通,能在多大的范围内进行变通等一系列问题。 Since our country is a unified multi-ethnic country with 55 ethnic minorities, it is very urgent to study and solve the issue of ethnic and common law conflicts. The practice of allowing ethnic autonomous areas to make modifications or additions without prejudice to the basic principles and basic spirit of the Constitution and laws according to their own local characteristics is very correct and necessary. This article attempts to study the limits of the flexible provisions of the ethnic autonomous areas from the perspective of the conflict between the customary laws and the laws of the ethnic minorities, as well as a series of questions such as what kind of principles should be adopted and how many variations can be made.
