In one line
India has no written constitutional right to a healthy environment and has had one in practice since the 1980s, built by reading Article 21 together with the two articles the Forty-second Amendment inserted, and in 2024 the Supreme Court added a right against the adverse effects of climate change.
In exam wording: the right to a healthy environment in India is a judicially developed facet of the right to life under Article 21 of the Constitution, read in the light of Article 48A, which directs the State to protect and improve the environment and to safeguard forests and wildlife, and Article 51A(g), which makes it a fundamental duty of every citizen to protect and improve the natural environment; in M.K. Ranjitsinh v. Union of India (2024) the Court held that Articles 14 and 21 also recognise a right against the adverse effects of climate change.
The provisions
Article 21. No person shall be deprived of his life or personal liberty except according to procedure established by law.
Article 48A. The State shall endeavour to protect and improve the environment and to safeguard the forests and wild life of the country. Inserted by the Constitution (Forty-second Amendment) Act 1976.
Article 51A(g). It shall be the duty of every citizen of India to protect and improve the natural environment including forests, lakes, rivers and wild life, and to have compassion for living creatures. Also inserted in 1976.
Article 48, which sits immediately before Article 48A, directs the State to organise agriculture and animal husbandry on modern and scientific lines and to prohibit the slaughter of cows and calves and other milch and draught cattle. It matters here only because it is the provision Article 48A was placed beside, in the chapter of directive principles.
Why the right had to be built rather than found
Because the Constituent Assembly did not think about it. In 1950 the environment was not a constitutional subject anywhere in the world. The Forty-second Amendment in 1976, four years after Stockholm, inserted the two environmental articles, but it put one in Part IV, which Article 37 makes unenforceable, and the other in Part IVA, which imposes duties on citizens and gives them no rights.
So the environment entered the Constitution in 1976 in the two places where nobody can sue on it. The right had to come from Article 21, which is enforceable.
The construction, step by step
- Article 21 protects life. Not mere animal existence, but life with dignity.
- Life with dignity requires a wholesome environment. Air, water and soil are the conditions of life, so their degradation is a deprivation of life within the meaning of Article 21.
- Articles 48A and 51A(g) show that the Constitution takes this seriously. They cannot be sued upon, and they can be used to interpret Article 21, because a right in Part III is read in the light of the directive principles.
- Therefore Article 21 includes the right to a wholesome environment, and it is enforceable under Articles 32 and 226.
The Indian Right to a Healthy Environment
That four-step argument is the one to reproduce in an examination, and each step has authority behind it.
The case that took it to climate
Facts. M.K. Ranjitsinh v. Union of India, (2024) 5 SCC 597. The Great Indian Bustard is a critically endangered bird whose habitat in Rajasthan and Gujarat is crossed by overhead power lines, on which the birds collide and die. The Court had earlier directed that the lines be laid underground across the priority habitat. The Union applied to modify that direction, saying that undergrounding transmission across that area would obstruct India's solar and wind programme and therefore its international climate commitments.
Held. The Court modified its earlier direction and appointed an expert committee to determine where undergrounding is feasible. In doing so it held that although Articles 48A and 51A(g) are not justiciable in themselves, read with Articles 14 and 21 they yield a right to a clean environment and, as a distinct right now needing articulation, a right against the adverse effects of climate change. Without a clean environment which is stable and unimpacted by the vagaries of climate change, the right to life is not fully realised; the right to health, which is part of the right to life, is affected by air pollution, shifting vector-borne disease, rising temperatures, drought, crop failure, storms and flooding; and the inability of underserved communities to adapt violates the right to equality as well.
Why it matters here. It is the point at which India's international climate obligations became the raw material of a constitutional right, and it is the most recent authority on this paper.
Worked example
A community near a proposed coal plant petitions a High Court. What does the right actually give them?
- Standing. Any member of the public affected may petition; the rules of standing are relaxed for environmental public interest litigation.
- A right, not a policy interest. They are not asking the court to prefer their policy. They are asserting Article 21.
- A burden. After Nayudu, the proponent must show that the project will not damage the environment, rather than the community having to prove that it will.
- A limit. The right does not forbid development. The court will apply sustainable development and balance, which is precisely what happened in Ranjitsinh, where the climate argument won and the bird's habitat was reopened to overhead lines outside a priority area.
The Indian Right to a Healthy Environment
That last point is worth making in an answer. The Indian right to a healthy environment is a right to have the environment weighed, not a right to have it prevail.
What it does NOT mean
Articles 48A and 51A(g) are not enforceable. Any answer that says a citizen can sue on Article 48A is wrong. Their function is interpretive.
The right is not absolute. It is balanced against development, and Ranjitsinh is a case where a climate consideration outweighed a species consideration.
It is not the same as the international right. The General Assembly recognised a right to a clean, healthy and sustainable environment in 2022 by resolution 76/300, which is soft law and binds nobody. India's right is enforceable in India and is older by four decades.
Quick revision
- Article 21 is the source; Articles 48A and 51A(g) are the interpretive support, both inserted by the Forty-second Amendment 1976.
- Article 37 makes the directive principles unenforceable, which is why the right had to come from Part III.
- Four steps: life with dignity, environment as its condition, directive principles as interpretive aid, right enforceable under Articles 32 and 226.
- M.K. Ranjitsinh v. Union of India, (2024) 5 SCC 597: a right against the adverse effects of climate change, recognised by Articles 14 and 21.
- General Assembly resolution 76/300 of 2022 recognised the right internationally; it is soft law.
Test yourself
1. Can a citizen sue on Article 48A? No. It is a directive principle and Article 37 makes it unenforceable. It is used to interpret Article 21, which is enforceable.
2. What new right did the Supreme Court articulate in 2024, and out of which articles? The right against the adverse effects of climate change, recognised by Articles 14 and 21 read with Articles 48A and 51A(g).
3. Why did the Great Indian Bustard lose part of its protection in a judgment that expanded environmental rights? Because the Court balanced the species interest against India's climate commitments and the solar and wind programme, and referred the question of feasible undergrounding to an expert committee. The Indian right requires the environment to be weighed, not to prevail automatically.
