CJI Surya Kant Says Supreme Court is a Banyan Tree for Environmental Justice

In a powerful address at the inauguration of the International Conference on 'The Future of Environment and Climate Dynamics' in New Delhi, Chief Justice of India Surya Kant painted the Supreme Court as a living, breathing banyan tree—its roots deep in the ethos of Indian civilization, its branches sheltering the environmental rights of future generations. Speaking alongside Prime Minister Narendra Modi, the Chief Justice underscored how the Court’s environmental jurisprudence has evolved from the mere text of the Constitution into a robust framework that balances development with ecological preservation.

“The Constitution of India is therefore not a mere political charter; it is the moral covenant with past, present, and future generations,” CJI Kant said. He emphasized that while the Constitution contains seeds of environmental protection—through Article 48A (State duty to protect the environment) and Article 50A (citizen duty to protect nature)—those seeds require the “nurturing water of judicial wisdom” to blossom. That wisdom, he argued, has been consistently delivered by the Supreme Court over four decades, transforming it into a guardian of environmental justice.

Roots in Civilisation, Branches in Jurisprudence

The Chief Justice traced the Court’s environmental journey to the landmark 1980 judgment in Municipal Council, Ratlam v Vardhichand , where the Supreme Court held that a citizen’s right to basic sanitation could not be subordinated to a municipality’s financial limitations. That decision, he noted, marked the beginning of a judicial philosophy that prioritizes human dignity and ecological health over administrative convenience.

In 1991 , the Court read the right to a pollution-free environment into Article 21 , elevating it to a fundamental right . Five years later, in 1996 , it imported two global environmental law principles into Indian jurisprudence: the precautionary principle and the polluter pays principle . In the same year, the Court established the doctrine of absolute liability for environmental harm, holding that enterprises engaged in hazardous activities are strictly liable for any damage they cause. Subsequently, the Court recognized the public trust doctrine , asserting that forests, rivers, and other natural resources are held by the State in trust for the benefit of the public, not as outright property.

“The same pattern has continued till date,” CJI Kant observed. He cited the recent articulation of “ eco-centric proportionality ,” a doctrine that demands rigorous environmental protection while engaging realistically with developmental needs. Under this approach, projects may proceed only with enforceable conditions, expert oversight, restoration obligations, compensatory afforestation, and accountability mechanisms. This, the Chief Justice said, has advanced a paradigm shift away from the binary of “either conservation or development” toward a harmonious integration of both.

Climate Change and the Expanding Frontiers of Fundamental Rights

Turning to contemporary challenges, CJI Kant highlighted the growing importance of climate change–induced rights, which raise “sharper constitutional questions” about equality, livelihood, health, and the conditions necessary for a meaningful life. He argued that climate-related disputes often involve cumulative ecological harm that transcends individual projects and jurisdictions. Courts, therefore, must look beyond immediate proposals and examine the larger ecological systems of which those projects form a part.

The Chief Justice drew on comparative environmental jurisprudence to illustrate this point. He noted that Nepal has recognized environmental protection as part of the right to life , while Sri Lanka connects sustainable development with finite natural resources and environmental responsibilities. The South African Constitution , he said, develops sustainable development as a framework for reconciling environmental protection with economic development. More strikingly, Brazil’s Supreme Federal Court has gone further by addressing not only individual environmental injuries but also governmental omissions and the very functioning of environmental policy. Similar efforts have been made by courts in Chile, Russia, and Armenia.

“Climate adjudication must therefore look beyond the immediate proposal and examine the larger ecological system of which that project forms a part,” CJI Kant emphasized. He pointed out that the energy transition will require new infrastructure, technology, and patterns of land and resource use. Cities will have to reconcile mobility, housing, and economic activity with air quality, water security, and ecological resilience.

Dialogue, Not Transplantation

A key theme of the Chief Justice’s address was the need for comparative environmental jurisprudence to be an exercise in dialogue rather than transplantation. “The tide of justice can’t flow in isolation,” he said. “It needs to draw strength from the tributaries of collective will, scientific wisdom, and international cooperation.” He urged courts around the world to share insights without merely copying foreign doctrines, instead adapting global principles to local contexts.

This vision aligns with the Supreme Court of India’s own history of selectively integrating international environmental law while grounding it in domestic constitutional values. The Court’s importation of the precautionary principle and polluter pays principle from global jurisprudence is a prime example of such adaptation.

The River of Progress Must Not Run Red

Concluding his address with a striking metaphor, CJI Kant said: “Our courts must become the bridge between the sagacity of our ancestors and the aspirations of our descendants, ensuring that the river of progress does not run red with the silt of destruction, through the rocky terrains of inaction and indifference.” He called on all stakeholders to ensure that “this river of responsibility never runs dry, and that it continues to flow strong and clear for generations to come.”

For legal professionals, the speech serves as a reaffirmation of the Supreme Court ’s proactive role in environmental governance. It also signals that the Court is prepared to engage with complex, systemic climate issues through an evolving toolkit of doctrines— eco-centric proportionality , public trust, and absolute liability—while remaining open to comparative insights. The emphasis on cumulative ecological harm and intergenerational equity will likely influence future litigation, particularly in cases involving large infrastructure projects, resource extraction, and climate policy.

As India faces mounting environmental challenges—from air pollution in cities to groundwater depletion and deforestation—the judiciary’s banyan-tree approach may prove indispensable. The roots are deep, the branches wide, and the shade, as CJI Kant suggested, is meant to protect generations yet unborn.
