Weight of decision 

As an appellate court of review, the ruling of the Multicompetent Chamber of the Provincial Court of Justice of Sucumbíos is binding on the state of Ecuador.

Key facts

The right to health is recognized and guaranteed in Article 32 of the Ecuadorean Constitution, but also in other international treaties binding on Ecuador, such as Article 10 of the Pact of San Salvador Protocol and Article 12 of the International Covenant on Economic, Social and Cultural Rights. The realization of a right to health is linked to the exercise of other rights, including rights to water and a healthy environment. Article 30 of the Constitution also guarantees people the right to live in a safe and healthy habitat; children and adolescents further have the right, in accordance with Article 45 of the Constitution, to have their integral health recognized and guaranteed.

On 20 February 2020, a group of nine girls from the provinces of Sucumbíos and Orellana filed a constitutional injunction (acción de protección) against the government of Ecuador. In their lawsuit, plaintiffs claimed that gas flaring is unlawful, although it can be authorized by exception, and that despite this, the State has made it a common practice, which constitutes a violation of their rights to health, water, food sovereignty, and a healthy environment, and the rights of nature. They furthermore argued that pollution of gas flaring causes serious impacts on the environment and on people’s health, damage to biodiversity and the cycles of nature, and contributes to climate change. Plaintiffs requested, inter alia, the annulment of all gas flaring authorizations, the immediate elimination of all flaring towers located in various areas of the Amazon where there is oil activity, and the prohibition of new oil-related flares in the region.

Previous instances

The first court to hear this case dismissed the constitutional injunction sought, stating that it wasn’t evident that there was a violation of constitutionally enshrined rights of the claimants. This verdict adopted the State’s stance that the presence of pollution should be redress via an administrative route, rather than a constitutional one.

Summary of holding

On 29 July 2021, the Provincial Court of Justice of Sucumbíos declared that “the Ecuadorian State has ignored the right of the plaintiffs to live in a healthy and ecologically balanced environment and their right to health by promoting polluting activities, and by refusing to use environmentally clean and energy-efficient technologies.” The Court indicated that the authorizations for gas flaring, as an activity associated with hydrocarbon production carried out by the Ecuadorian State, disregards various international commitments made by Ecuador in environmental matters. Among the most important of those commitments are Ecuador’s Nationally Determined Contributions, agreed to during the COP 21 meeting for the United Nations Framework Convention on Climate Change.

As a result, the Court ordered an update to the plan to provide for the gradual and progressive elimination of the gas flares, with those located in places close to the populated centers being the first to be removed within 18 months, and all gas flares to be removed by December 2030. In addition, the Ministry of Energy and Non-Renewable Natural Resources may grant authorizations for new clean technologies located away from populated centers.


Potential takeaways for future climate migration litigation 

  • The decision in the Caso Mecheros – as it is commonly known – in responding favourably to a lawsuit filed by nine girls from the Amazon, was received as a historic triumph. It creates legal precedent for displaced populations in Ecuador, insofar as it links the consequences of gas flaring with violations of fundamental, constitutionally enshrined rights.
  • The judgment highlights the adverse health effects, including cancer, suffered by numerous citizens because of the pollution caused by gas flaring. Consequently, it is arguable that the prohibition of gas flaring, as mandated by the court’s decision, should be integrated into the public policies to other countries in the near future. The evidence presented by the plaintiffs, detailing the detrimental health impacts stemming from gas flaring, could be presented to underscore this point. Furthermore, an additional line of argument could be established on the premise that the gas flaring has compelled the population to relocate due to the direct infringement on their health and well-being.
  • The rights at stake predominantly pertain to third-generation human rights, encapsulating the social, cultural, economic, and environmental aspects of individual and communal welfare. This connects to a growing trend in Latin American jurisprudence, whereby the rights of nature, indigenous groups, and future generations, and international climate commitments, have been found enforceable by national courts (see, e.g., summaries of cases from Colombia, Paraguay, and Suriname).
