On May 25, 2020, Greenpeace Mexico filed a lawsuit against the Mexican government contesting the constitutionality of two electricity sector policies that would limit renewables. Greenpeace Mexico asked the Administrative Court to declare the policies unconstitutional for violating the rights to a healthy environment and sustainable development and for obstructing Mexico's compliance with its international commitments to tackle climate change. The two policies challenged were the National Centre of Energy Control (CENACE) Agreement "to ensure the efficiency, quality, reliability, continuity and safety of the National Electric System, on the occasion of the COVID-19 epidemic" and the Ministry of Energy policy of "Reliability, Security, Continuity and Quality in the National Electrical System." The former ordered the suspension of certain wind and photovoltaic power plants in operation or on the approval stage prior to commercial operation. The latter supported the CENACE Agreement's suspension of renewable energy power plant operation and the promotion of oil-based power generation. Greenpeace filed the case in the Mexico City's Second District Administrative Court Specialized in Economic Competition, Broadcasting, and Telecommunications.
On June 23, 2020, the district court issued a preliminary injunction to suspend the effects of the contested acts. On November 17, 2020, the district court held its main hearing. The Court then issued its judgment that the public policies were unlawfully modifying the rules of the energy market, and were violating the right to a healthy environment of Mexicans. The government appealed the decision to the First Circuit Collegiate Tribunal.
