Federal Judges Clear Last Injunction Against Maya Train Cargo Project

Cancún, Quintana Roo — Federal judges have cleared the final legal hurdle for an injunction against the Maya Train cargo project, ruling that a federal court in Quintana Roo must hear the case challenging environmental approvals granted to the Mexican Army.

Magistrates from the Third Collegiate Circuit Court of Quintana Roo determined on February 3 that no jurisdictional conflict exists in case 26/2025, resolving a five-month dispute over which court should handle the lawsuit.

The Mexican Center for Environmental Law (Cemda) filed the injunction in September against the environmental authorization the Ministry of Environment and Natural Resources (Semarnat) granted to the army, which is leading the project. Cemda argued officials approved the authorization amid legal irregularities, failing to consider critical ecological factors in the environmental assessment.

The case initially went to the Fifth District Court, but the federal judge there declined to proceed, citing a 2021 agreement that designated the First District Court of Yucatán to resolve such disputes. When that court also refused to take the case in October 2025, it triggered the jurisdictional conflict.

The magistrates upheld a proposal from Lenin Salvador Zenteno Ávila, finding no actual conflict since the 2021 agreement was merely an administrative procedure. They ordered the Fifth District Court of Quintana Roo, the original federal court, to resolve the injunction against the Maya Train cargo operation.

The court will now determine whether to issue a suspension against new federal government actions related to the project.
