Community Representative of San Bartolo Coyotepec v. State of Oaxaca

Summary:
On 11 March 2024, a representative of the community of San Bartolo Coyotepec in Mexico’s State of Oaxaca filed an amparo petition with the Ninth District Court of the State of Oaxaca, arguing that the human right to a healthy environment had been violated because municipal, state, and federal authorities had failed to protect Benito Juárez National Park and the corresponding Ecological Reserve and Protected Natural Area. On 20 March 2025, the case was rejected by the Ninth District Court given the failure to demonstrate a concrete, direct, and imminent harm resulting from the alleged failure to protect the designated areas.

The applicant appealed, arguing that the first instance judge had failed to reason his decision, had shifted the burden of proof to his detriment, and had improperly evaluated the evidence concerning the progressive deterioration of the protected natural areas in question.

On 20 October 2025, the Supreme Court of Justice of Mexico accepted the case for review. On 24 February 2026, the Plenary Session of the Supreme Court of Justice ordered that the case be remanded to the Ninth District Court to amend the ruling that denied constitutional protection, gather evidence and determine whether the applicant’s human right to a healthy environment had been violated. It established that, pursuant to Article 4 of the Mexican Constitution, which enshrines the right to a suitable environment, any person who inhabits or uses an ecosystem and benefits from its environmental services may go to court to demand its protection, without needing to prove direct individual harm.

In doing so, the Court explicitly linked the case to climate change. It noted the interconnectedness of the three aspects of the ‘triple planetary crisis’ (climate change, biodiversity loss and pollution), and held that none of these aspects can be treated in isolation from each other. It noted the applicant’s framing of the territory in question as a carbon sink. It also extensively cited the 2025 advisory opinions on climate change of the International Court of Justice and the Inter-American Court of Human Rights (IACtHR). It particularly emphasized the IACtHR’s finding that “urged States to maximize the scope of protection of the right to the environment, recognizing that this right protects not only individuals, but also the components of the environment—such as forests, rivers, seas, and other ecosystems—as autonomous legal interests, even in the absence of certainty or immediate evidence of a direct risk to specific individuals” (para. 43). In doing so, it noted that according to the IACtHR climate change poses an imminent risk to life, health, food security, and the balance of ecosystems on a global scale (para. 42), as well as extensively citing the ICJ’s discussion of the right to a healthy environment in its climate advisory opinion (para. 35).

With this decision, the Court reaffirmed the “adjacent environment” doctrine in environmental matters. This means that individuals who live in or use the area of influence of an ecosystem and receive its environmental benefits may file an amparo petition, even if they do not live immediately adjacent to the Protected Natural Area. Furthermore, the Court noted that environmental protection must be analyzed in accordance with the precautionary principle, meaning that the absence of scientific certainty regarding the benefits of the ecosystem in question cannot be used to deny its protection or to disregard the relationship between people and the natural environment.

Mexican Center for Environmental Law v Mexico

Summary:
This case revolves around the 2020 amendments to Mexico’s General Law on Climate Change, specifically the termination of the Climate Change Fund established in 2012. The fund’s purpose was to attract and direct resources, both national and international, towards climate change initiatives. The Mexican Center for Environmental Law (CEMDA) filed a petition seeking legal protection to annul this aspect of the reform, arguing that it was regressive in safeguarding the human right to a healthy environment and exacerbated transparency issues. The initial court ruling dismissed the request, stating that the reform did not impede any rights but rather reallocated resources to the Federal Expenditure Budget. CEMDA appealed to a Collegiate Tribunal, which, recognising the case’s significance, referred it to the Mexican Supreme Court. On 12 April 2023, the Supreme Court maintained that judges should not assess the suitability of public policies, emphasising that climate change strategy falls under the executive and legislative branches’ jurisdiction. The Court upheld the prior decision, rejecting CEMDA’s claim.

Claim:
The contention in this case asserts that eliminating the Climate Change Fund through the 2020 amendments to Mexico’s General Law on Climate Change infringes the constitutional right to a healthy environment. CEMDA contends that this modification impedes the effective addressing of climate change by dismantling a dedicated fund intended to attract public and private resources for climate-related actions. In addition, CEMDA maintains that the reform gives the government discretionary power to utilise these same resources to support fossil fuels, potentially putting Mexico’s international commitments to environmental preservation at risk. Thus, the fundamental issue at hand is whether the elimination of the Climate Change Fund breaches the constitutional right to a healthy environment.

Decision:
On 12 April 2023, the Mexican Supreme Court ruled that the elimination of the Climate Change Fund does not violate the constitutional right to a healthy environment. The Court held that it is not within the jurisdiction of judges to evaluate the suitability of public policies; such decisions fall under the purview of the executive and legislative branches. The Court emphasised that the modification of the strategy to combat climate change, including the dissolution of the Climate Change Fund, is a matter of public policy, and legislators have the freedom to determine appropriate mechanisms. The Supreme Court concluded that CEMDA’s arguments failed to demonstrate the unconstitutionality of the reform. Moreover, the Court found no evidence that the resources formerly allocated to the Climate Change Fund, post-modification, would not be used correctly, transparently, and equitably. Consequently, the lower court’s decision was upheld, and CEMDA’s claim was rejected.

Youth v. Government of Mexico

Summary:

On 5 December 2019, the plaintiffs filed for protection against several authorities and acts. Notably, they claimed that the President of the Republic, the Head of the Ministry of Environment and Natural Resources, the Inter-Ministerial Commission on Climate Change, and other authorities had failed to issue regulations and policies regarding climate change which they were required to by national law. The plaintiffs claim that the failure to issue such regulations and policies had violated their constitutionally protected rights. They invoke, among other rights, the right to health protection, the right to a healthy environment, the right to water and the rights of children.

In a decision by the District Court in Administrative Matters in Mexico City, on 20 May 2022, the case was dismissed on the basis that the plaintiffs lacked a legitimate interest, as required to claim the alleged legislative omissions. The court argued that the plaintiffs could not prove a link between themselves and the environmental services of the allegedly violated ecosystem, as required by Mexican law.

The Collegiate Court in Administrative Matters in Mexico City, the appeals court, overruled this decision on 21 September 2022. It stated that the plaintiffs do have a legitimate interest because the legislative omissions affect the entire national territory and the applicants intend to counteract climate change and prevent its effects. Hence, a special link to ecosystems or the environment is not required because, as long as the plaintiffs reside in the national territory, such a link is established.

The case was forwarded to the Supreme Court of Mexico, where it is currently pending, to clarify the issue of the alleged human rights violations.

Greenpeace Mexico v. Ministry of Energy and Others (on the National Electric System policies)

Summary:

In Spring of 2020 the Government of Mexico issued the following two policies: The Agreement of the National Centre of Energy Control (CENACE) “to ensure the Efficiency, Quality, Reliability, Continuity and Safety of the National Electric System, due to the recognition of the SARS-CoV2 virus disease epidemic (COVID-19)” and the Ministry of Energy’s “Reliability, Security, Continuity and Quality in the National Electrical System” policy. The directives provided for the closure of
renewable energy power plants and promoted oil-based power generation on the grounds that intermittent generation has a negative impact on the national power grid.

On 25 May 2020 Greenpeace filed a lawsuit against the Government of Mexico before the District Court in Administrative Matters in Mexico City. Greenpeace argued that the policies violated the constitutional rights to a healthy environment and sustainable development and Mexico’s international environmental commitments to reduce CO2 emissions.

Both the District Court and the First Circuit Collegiate Tribunal (appeals court) found the policies to violate constitutional rights and international climate agreements.

Claims:

Greenpeace claimed that the right to a healthy environment and numerous international agreements, namely the United Nations Framework Convention on Climate Change, the Kyoto Protocol, and the Paris Agreement, had been violated. Both policies would diminish environmental protection and increase CO2 emissions. This would contravene the named conventions and would violate the constitutional right to a healthy environment.

Decision:

The appeals court ruled that, besides the fact that the authorities were not competent to issue the policies in question, the implementation of those policies would violate the right to a healthy environment. Encouraging the production and consumption of fossil fuels generates more greenhouse gas emissions which pollute the environment and thus damage the right to a healthy environment. In its decision, the court relied on the principles of in dubio pro natura, civic participation, non-regression, and the inclusion of future generations.

Greenpeace Mexico v. Ministry of Energy and Others

Summary:
This indirect amparo suit was brought by Greenpeace Mexico against the Mexican government, contesting the Mexican Sectoral Energy Plan for 2020-2024. Greenpeace argued that this policy promotes the use of fossil fuels over sustainable energy sources, thereby violating fundamental rights. The case invokes the pro persona principle and the human and constitutional rights to equality, a healthy environment, the protection of health, and access to renewable energy, as well as the legality principle. It also invokes the principle of progressive interpretation of human rights and the concept of positive and negative obligations.

In 2020, a Mexico City District Court ordered the suspension of the policy in an injunction.

Procedural steps:
The Third District Administrative Court for Mexico City declined to hear the case on grounds of lack of specialization in the matter. On 8 September 2020, the Mexico City District Court accepted to hear the case.

On 21 September 2020, the Mexico City District Court issued an injunction suspending the Sectoral Energy Plan (2020-2024). The court noted the imminence and irreparability of the harms at stake, finding that the it was an ‘indisputable fact’ that the limitation of the production and use of renewable energies encourages the operation of conventional electricity generation technologies using fossil fuels and thereby causing greater emissions, which affects human healthy and the environment. Because of this, the degree of imminence and irreparability of the risk at stake did not require specific proof, because it had been established through logical reasoning (p. 29).
