The convention to eliminate all forms of discrimination against women (CEDAW), has indicated that discrimination is understood as “any distinction, exclusion or restriction based on sex (…) in the political, economic, social, cultural and civil or in any other sphere “; politics has been one of the substantive areas in which the situation of inequality between women and men is expressed, its devices and structures have restricted the right of women to access and participate in the same way as men in political spaces and of decision making. In the constitutional reform of 2014 in electoral political matters, a decisive step was taken to eliminate the legendary discrimination of women that has existed, in the political-electoral sphere, especially in the active participation of women in political life of the country, their right to be voted in positions of popular election, on equal terms with men, with a gender parity. In the present work, it is not only intended to carry out a study of this relevant constitutional reform in political-electoral matters, through which, among other issues, gender parity was addressed; but also, a study of the right to be voted from the gender parity approach will be carried out in light of the criteria of the Electoral Tribunal of the Federal Judicial Branch.
