Model examples of constitutional design can be found in recent constitutions in different regions. Since 1981, in many countries in the Western region, constitutions have been amended to include provisions permitting the use of temporary special measures to promote the participation of women in political and public life. One recently established constitution in the Maghreb confers systematically, throughout its provisions, constitutional rights expressly on women as well as men, and seeks to ensure parity between them; in Latin America and the Caribbean there is a constitution which contains approximately 34 references to the rights of women, including the right to political participation.
