Mexico is at the center of the global battle over abortion. In 2007, a watershed reform legalized the procedure in the national capital, making it one of just three places across Latin America where it was permitted at the time. While abortion care is now available on demand and free of cost through the Mexico City Ministry of Health, abortion laws have grown harsher in several states outside the capital as part of a coordinated national backlash. In this book, Elyse Ona Singer argues that while pregnant women in Mexico today have options that were previously unavailable, they are also subject to the expanded reach of the Mexican state and the Catholic Church over their bodies and reproductive lives. By analyzing the moral politics at clinical encounters in Mexico City's public abortion program. Lawful Sins offers a critical account of the relationship among reproductive rights, gendered citizenship, and public healthcare.
