Mexico's Supreme Court (SCJN) exercised its jurisdiction-attraction authority on Monday, August 10, over the legal challenges contesting changes to the urban plan for Mahahual, Quintana Roo, tied to Royal Caribbean's Perfect Day México megaproject. The Court will determine whether three amparo petitions filed by local residents should have been admitted.
The case originates from three amparo proceedings brought by Mahahual residents against modifications to the Urban Development Program approved by the municipality of Othón P. Blanco. According to El Financiero, the municipality raised the maximum building height from 14 to 63 meters, and a federal district court dismissed the claims. The Court is now reviewing whether those claims should have been admitted. The analysis focuses on how those changes enabled the cruise line to present its project to the environmental authority. Although the federal government has stated that the company withdrew, Royal Caribbean indicated in its second-quarter investor call that it still considers the project viable.
Attorney Irma del Carmen Morales of the civil association Defendiendo el Derecho a un Medio Ambiente Sano (DMAS) explained that the Court will analyze whether the three claims filed by Mahahual residents, which a federal court dismissed, should have been admitted. The case arrives via complaint proceedings 76/2026, 112/2026, and 113/2026, derived from amparos 57/2026, 129/2026, and 134/2026. According to Expansión Política, the Court may also rule on communities' standing to challenge urban planning decisions, the deadlines for environmental amparo cases, and the application of principles such as the precautionary principle and in dubio pro natura. Should the amparos advance, the next step will be to review the legality of the land-use change. A ruling on deadlines, Morales said, "would serve many environmental struggles across the country."
The Court's ruling could set nationally binding criteria for how communities defend their territory against urban changes with environmental impact, as Expansión Política notes. The decision will establish deadlines for environmental litigation across the country and provide a concrete basis for returning to this case.
