This policy guidance provides a range of good practice options for advancing gender equality in the content of constitutions. It contributes to, and complements, the capacity-building support that United Nations Development Programme (UNDP) staff in country and regional offices provide to a range of national partners and stakeholders for different aspects of constitution-making (which includes but is not limited to support for the drafting of new constitutions and the revision of existing constitutions). Other UNDP initiatives provide guidance and support for the process of constitution-making. This policy guidance is designed to build the capacity of UNDP staff to advocate for the advancement of gender equality and women’s human rights in the content of constitutions. It is intended to provide technical support for a range of partners and national stakeholders involved in constitution-making, including; legislatures, constituent assemblies, constitutional review committees or commissions, governments, civil society organizations and legislative drafters. Through the inclusion of numerous examples from existing constitutions, it aims to foster UNDP entry points for pursuing South–South exchanges through which countries can benefit from, and utilize, the good practice constitutional provisions of similarly situated countries. It also aims to raise awareness of the importance of advancing gender equality in the content of constitutions. With this in mind, examples have been chosen based on the de jure constitutional formulation rather than the record of gender equality in the particular country.
