This publication provides a brief history of past constitutions in Nepal. It includes a more detailed examination of the substance of the 1990 Constitution, analyzing its strengths and weaknesses, as a means to provide a better understanding of the current issues and debates. It also identifies proposals and controversies surrounding political reform and provides cross-reference to the experiences of other countries relevant to the current process in Nepal. The publication does not offer particular solutions; rather it provides an analysis of different options that emerge when making a new constitution. It aims to encourage full participation in the process of constitution making by introducing readers to constitutionalism, the roles of constitutions, and to key constitutional concepts, relating the latter to the current issues of political reform.
