This book attempts to assess the efficacy of individuals and institutions in enforcing international legal pressure concerning abortion on Mexican national legislation. It compares Mexican states of Distrito Federal and Guanajuato, as an opportunity to show the development, change and execution of rules on abortion in Mexico as a whole, particularly from 1994 to 2013. To conduct this research the author spent 6 weeks in Mexico interviewing important figures such as politicians and activists from various international, national and local organizations that deal with women s rights - particularly those concerning abortion, in order to centralize the topic of abortion rights and its practical usage.
