Negative public perceptions regarding biotechnology have influenced political will. The Mexican Supreme Court and the National Commission on Human Rights established that indigenous groups in the state of Yucatan where the release of transgenic crops into the environment is sought must be consulted prior to granting commercial permits. Although it goes against the Federal Biosafety law, in October 2016, Yucatan declared its state ¨Genetically Modified Organism (GMO) ¨ free zone, to include crops and all GE products. The states of Quintana Roo and Campeche have proposed to adopt a decree similar to that of Yucatan during the Conference of the Parties, COP8 in Cancun. Mexico City and the state of Tlaxcala have decreed their states ¨GMO¨ free zone, to include GE crops in 2009 and 2011, respectively.
