Court: Supreme Court of India
Bench: Justice Kuldip Singh, Justice Faizan Uddin, and Justice K. Venkataswami
Date of Judgment: 28th August, 1996
Relevant Statutes/Key Provisions: Article 21 of the Constitution of India and section 3(3) of the Environment (Protection) Act, 1986
Brief Facts:
A PIL under Article 32 of the Indian Constitution has been filed by an NGO named Vellore Citizens Welfare Forum regarding the pollution caused by the large discharge of untreated sewage from tanneries and other industries into agricultural lands, open areas, and waterways, ultimately flowing into the Palar River, which is the main water source for residents of that region. It was claimed that this untreated sewage had contaminated the entire water surface, including the subsurface, rendering water inaccessible to locals.
According to a study conducted by the Tamil Nadu Agricultural University Research Centre, chemical and dye contamination has rendered over 35,000 hectares of cropland in the tanneries belt unsuitable for cultivation, compromising groundwater and soil quality. 350 of the 467 surveyed wells were found to be contaminated. Furthermore, out of 584 tanneries, only 443 had applied for board approval for their operations, indicating non-compliance with rules.
Issues Raised:
- Should the tanneries be allowed to continue operating at the cost of the environment, the health, and the lives of thousands of people?
Arguments:
Petitioner argued that:
- Discharge has contaminated the surface and subsurface water of the Palar River, making it difficult for residents to access safe drinking water.
- Presented a survey report from Peace Members, a non-governmental group, which found pollution in 350 of 467 drinking and irrigation wells across 13 towns in the Dindigal and Peddiar Chatram Anchayat Unions.
- Led to acute water scarcity, requiring women and children to travel long distances to fetch safe drinking water
Respondent argued that:
- The Total Dissolved Solids (TDS) limits set by the Tamil Nadu Pollution Control Board (TNPCB) were unreasonable.
Judgment:
The court concluded that because the leather industry creates jobs for citizens and generates foreign exchange, it is a vital component of the country’s development. Development and environmental protection, however, must proceed in harmony. These tanneries endanger human life and harm the environment. Tanneries were ordered by the Supreme Court to cease operations until pollution control equipment was installed. If the Tamil Nadu Pollution Board grants them approval after installation, they can carry on with their work. The court suggested that MC Mehta be awarded Rs 50,000 in recognition of his noteworthy work. Establishing green benches is necessary to improve quick protection against environmental problems. In compliance with the guidelines provided in Section 3(3) of the Environment (Protection) Act, 1986, the Court ordered the Central Government to establish an authority.
Ratio Decidendi:
The Vellore Citizens Welfare Forum v. Union of India case’s ratio decidendi can be summed up like this:
- Polluter Pays Principle: The court said that people who harm the environment must pay for the damage and the costs of fixing it. This principle says that economic growth shouldn’t hurt the environment.
- The right to a clean and healthy environment: The ruling made it clear that Article 21 of the Indian Constitution protects the right to a clean and healthy environment as part of the right to life. It is the state’s job to keep the environment safe and make sure that everyone is healthy.
- Precautionary Principle: This says that when there is uncertainty about environmental harm, steps should be taken to protect the environment and public health.
The court used these ideas to decide to close down tanneries that were polluting the environment and to make environmental rules stricter.
Obiter Dicta:
The obiter dicta included several significant observations by the court that, while not essential to the decision, provided valuable insights into environmental law and policy. The court emphasised the importance of sustainable development, advocating for a balance between industrial growth and environmental protection to ensure ecological integrity. It also highlighted the role of public participation in environmental decision-making, suggesting that communities should have a voice in matters affecting their health and environment. Furthermore, the court remarked on the inadequacy of existing environmental regulations, calling for more stringent measures to prevent pollution and protect natural resources. Lastly, the court underscored the role of judicial activism in environmental matters, indicating that the judiciary should take proactive steps to enforce environmental rights and hold polluters accountable. These observations reflect the court’s broader concerns regarding environmental governance and the responsibilities of various stakeholders in safeguarding a healthy environment for future generations.
Final decision:
The judgment underscored the necessity for industries to implement pollution control measures before resuming operations. It also directed the establishment of Green Benches to expedite environmental cases and ordered the state of Tamil Nadu to pay legal fees to MC Mehta for his efforts in the case. The court’s ruling highlighted the importance of sustainable development, ensuring that economic growth does not come at the expense of environmental degradation and public health.
