An administrative tribunal has ruled that the Mexican Congress must begin work on legislation to ban single-use plastics, recognising their impact on health and the environment and the state's duty to prevent exposure to toxic substances. The injunction was filed by Greenpeace Mexico, El Poder del Consumidor and the Red Mexicana de Acción Ecológica, a member of the Colectiva Malditos Plásticos and Break Free From Plastic.

The injunction against Congress is part of the organisations' follow-up to two rulings by the Second Chamber of the Supreme Court in which it granted an appeal to the soft drinks industry, invalidating the ban on single-use plastics such as PET and expanded polystyrene in the state of Oaxaca.

This set a very negative precedent for the progressive protection of human rights and health, and was a clear setback for previously won environmental rights.
