Legislators in Mexico have blocked a government proposal to extend same-sex marriage provision across the country. The Commission on Constitutional Matters voted 18-9 against such a move, thwarting the initiative of President Enrique Peña Nieto. The commission argued that such an extension would violate the right of individual states to set their own civil registry rules. Same-sex marriage is currently legal in 11 of Mexico’s 31 states. The National Front for the Family, which organised mass demonstrations across the country when President Nieto first proposed the extension, is now calling on the nation’s Senate – via a citizens’ initiative – to enshrine traditional marriage as between one man and one woman in the constitution.
