The Supreme Court closed a suo motu case from 2021 regarding the remediation of polluted rivers, after approximately five years of inaction. The court directed the National Green Tribunal (NGT) to reopen the case and ensure continued monitoring. The Supreme Court questioned the feasibility of examining the extent of pollution in rivers across the country. The case was initiated in January 2021, when the court took cognisance of the contamination of rivers by sewage. The court was also hearing a plea by the Delhi Jal Board regarding pollutants being discharged into the Yamuna River by Haryana.

The Supreme Court's decision reflects concerns about the practical challenges of directly overseeing river pollution across the nation. By transferring the case to the NGT, the court aims to ensure continued monitoring and action at a more localized and specialized level.

This development is relevant for understanding environmental governance and the roles of different institutions in India, particularly for UPSC aspirants preparing for exams related to environment and ecology (GS Paper III).

In Simple Words

The Supreme Court started a case about polluted rivers back in 2021, but not much happened in five years. Now, they've asked the National Green Tribunal (NGT), a court for environmental issues, to take over and keep an eye on things. The court felt it was too difficult for them to check every polluted river in the country.

India Angle

Many Indian communities depend on rivers for drinking water, farming, and daily needs. River pollution affects everyone, from villagers to city dwellers, impacting their health and livelihoods.

For Instance

Imagine if your local lake was full of garbage. The government might start cleaning it, but if they don't keep checking on it, it could get polluted again. The NGT is like the regular inspector making sure the lake stays clean.

Clean rivers are essential for our health and economy. When rivers are polluted, it affects the water we drink, the food we grow, and the overall environment we live in.

Clean rivers, healthy lives: It's everyone's responsibility to keep our rivers pollution-free.

The Supreme Court closed a suo motu case from 2021 on remediation of polluted rivers after five years of near inaction. It directed the National Green Tribunal (NGT) to reopen the case and ensure continued monitoring. The court questioned the feasibility of examining the extent of pollution in rivers across the country.

The case was initiated in January 2021, with the court taking cognisance of the contamination of rivers by sewage. The court was also hearing a plea by the Delhi Jal Board regarding pollutants being discharged into the Yamuna by Haryana.

Expert Analysis

The Supreme Court's closure of the suo motu case on polluted rivers highlights the complexities of environmental governance in India and the roles of different institutions. The National Green Tribunal (NGT), established in 2010 under the National Green Tribunal Act, is a specialized body equipped to handle environmental disputes. By directing the NGT to reopen the case from January 2021, the Supreme Court is delegating the monitoring and enforcement responsibilities to an expert body with the necessary resources and expertise to address the issue of river pollution, particularly the contamination of rivers by sewage as originally noted in the case.

The concept of Suo Motu Cognizance, which the Supreme Court invoked in January 2021, refers to the court's power to take up cases on its own initiative, without waiting for a formal petition. This power is derived from Article 32 of the Constitution, which grants the Supreme Court the authority to issue writs for the enforcement of fundamental rights. In this instance, the court took suo motu cognizance of the contamination of rivers by sewage, recognizing the severe environmental and public health implications. The closure of the case after five years suggests a shift in strategy, with the court opting for a more decentralized approach through the NGT.

The issue of river pollution is directly linked to the fundamental right to a clean environment, which, while not explicitly mentioned in the Constitution, has been interpreted by the Supreme Court as an integral part of Article 21 (Right to Life). The discharge of pollutants into the Yamuna River by Haryana, as highlighted in the Delhi Jal Board's plea, poses a direct threat to the health and well-being of citizens who depend on the river for their water needs. The Supreme Court's initial intervention and subsequent transfer of the case to the NGT underscore the judiciary's role in safeguarding this fundamental right.

For UPSC aspirants, understanding the roles and responsibilities of the Supreme Court and the NGT in environmental protection is crucial for both prelims and mains. Questions may arise regarding the powers of the NGT, the scope of Article 21, and the concept of suo motu cognizance. Furthermore, the case highlights the inter-state water disputes and the challenges in ensuring effective environmental governance across different jurisdictions.

Background

The National Green Tribunal (NGT) was established in 2010 under the National Green Tribunal Act, 2010, to handle environmental disputes in India. The NGT's mandate is to provide effective and speedy disposal of cases relating to environmental protection, conservation of forests and other natural resources, and enforcement of any legal right relating to the environment. It operates on the principles of sustainable development, precaution, and polluter pays. The Supreme Court's suo motu case on polluted rivers, initiated in January 2021, stemmed from growing concerns about the deteriorating water quality in major rivers across India due to sewage and industrial effluents. The court's decision to take cognizance of the issue reflects its role as the guardian of fundamental rights, including the right to a clean environment, which has been interpreted as part of Article 21 of the Constitution. The Delhi Jal Board's plea regarding the pollution of the Yamuna River by Haryana further underscored the urgency of addressing inter-state water pollution issues. The Water (Prevention and Control of Pollution) Act, 1974, is a key legislation aimed at preventing and controlling water pollution in India. It establishes the Central Pollution Control Board (CPCB) and State Pollution Control Boards (SPCBs) to monitor water quality, set standards for effluent discharge, and take action against polluters. Despite these legal frameworks, the effective implementation and enforcement of environmental regulations remain a significant challenge, as highlighted by the Supreme Court's initial intervention and subsequent transfer of the case to the NGT.

Latest Developments

In recent years, there has been increased focus on river rejuvenation and pollution control through initiatives like the Namami Gange Programme, launched in 2014 to clean and protect the Ganga River. The program involves various activities, including sewage treatment infrastructure development, riverfront development, and afforestation. However, challenges remain in achieving the desired outcomes due to issues such as inadequate infrastructure, lack of coordination among different stakeholders, and limited community participation. The Central Pollution Control Board (CPCB) continues to monitor water quality across the country and publishes reports on the status of various rivers. These reports often highlight the high levels of pollutants, including organic matter, heavy metals, and fecal coliform bacteria, in many rivers. The government has also been promoting the use of technologies like constructed wetlands and bioremediation for wastewater treatment. Looking ahead, the focus is on strengthening regulatory frameworks, promoting sustainable industrial practices, and enhancing community awareness and participation in river conservation efforts. The Jal Shakti Ministry is playing a key role in coordinating these efforts and promoting integrated water resources management at the national level. The success of these initiatives will depend on effective collaboration between the central and state governments, as well as active involvement of local communities and civil society organizations.

Frequently Asked Questions

1. Why did the Supreme Court close the suo motu case on river pollution after 5 years of 'inaction'?

The Supreme Court likely closed the case because it questioned the practicality of directly monitoring river pollution across the entire country. Instead, it transferred the responsibility to the National Green Tribunal (NGT), which is specifically designed to handle environmental issues. This suggests the Supreme Court felt it lacked the resources or expertise for continuous, nationwide monitoring.

2. What is the difference between a 'suo motu' case and a case filed by an individual or organization?

A 'suo motu' case is when a court takes up a matter on its own, without waiting for someone to file a formal complaint. This usually happens when the court notices something of public importance, like severe river pollution in this instance. Regular cases are initiated by individuals or organizations who feel their rights have been violated.

3. How does this Supreme Court decision relate to the National Green Tribunal (NGT)? What is the NGT's role?

The Supreme Court has directed the NGT to reopen and monitor the case concerning polluted rivers. The NGT was established in 2010 to handle environmental disputes. Its role is to provide speedy disposal of cases related to environmental protection and conservation, operating on principles of sustainable development.

4. What is the significance of the year 2021 in this context for UPSC Prelims?

2021 is the year the Supreme Court initiated the suo motu case on polluted rivers.
