Mérida, Yucatán — Maya communities from four regions of Yucatán have won a definitive suspension in an amparo lawsuit that orders environmental authorities to conduct inspections, supervision, and technical visits to pig farms accused of causing environmental and health damage.
The ruling was issued in amparo case 1111/2026, filed by residents of Kinchil, San Rafael, Santa Teresa Coahuila and Paraíso in Maxcanú, Chocholá, and Santa María Chí in Mérida. The plaintiffs challenged a coordination agreement signed by the federal Environment Ministry (Semarnat), the Federal Environmental Protection Agency (Profepa), and Yucatán’s Sustainable Development Department (SDS) that governs environmental impact assessment of pig farms.
The communities argued that authorities failed to carry out a prior, free, and informed consultation even though the agreement would affect indigenous territories. They also said that complaints about environmental damage from pig farm operations were never followed up with timely inspections or corrective measures.
Under the definitive suspension, a federal judge ordered the competent authorities to inspect and supervise the installation and operation of pig farms located in the communities that filed the lawsuit. The inspections must verify compliance with current environmental regulations; if irregularities are found, authorities must exercise their legal powers to protect the environment and public health.
The agencies involved must also report to the federal court on the actions taken and any corrective or sanctioning measures applied.
The legal process is supported by lawyers from the Federal Institute of Public Defense (IFDP), who represent the communities.
The Maya communities said the ruling represents progress in defending their collective rights, particularly access to water, a healthy environment, health, and participation in public decisions that may affect their territories.
The case continues as the court considers the merits of the amparo, including the legality of the challenged agreement and the environmental authorities’ obligations to supervise pig farms in Yucatán.
