Dinesh Chahal v. Union Of India is a landmark judgment delivered by the National Green Tribunal (NGT) on February 6, 2020. The case centers around the environmental concerns arising from the operation of brick kilns in Haryana, particularly focusing on the adoption of Zig-zag Technology versus Conventional Fuel-Based Technology (FCBTK) for brick kiln operations. The petitioner, Dinesh Chahal, challenged the extension of the time limit for adopting environmentally friendly technologies without adequate scientific studies on ambient air quality and carrying capacity assessments.

The NGT examined the validity of an order by the Director, Food, Civil Supplies and Consumer Affairs, Haryana, which extended the deadline for adopting Zig-zag Technology in brick kilns outside the National Capital Region (NCR) until July 31, 2019. The Tribunal found this extension problematic due to the absence of scientific studies on air quality and the area's carrying capacity. Citing previous Supreme Court decisions, the Tribunal emphasized the necessity of adhering to environmental norms and the 'Precautionary Principle.' The NGT directed Haryana and the Central Pollution Control Board (CPCB) to conduct comprehensive studies on air quality and the impact of brick kiln operations, particularly focusing on the use of agricultural residues as fuel.

Precedents Cited

The Tribunal extensively referenced several pivotal Supreme Court judgments, notably:

• M.C. Mehta v. Union of India (1998, 2000, 2002): These cases directed the closure or relocation of brick kilns to mitigate environmental degradation.
• K. Guruprasad Rao v. State of Karnataka (2012): This judgment underscored the necessity for brick kilns to adopt improved emission technologies.
• M.C. Mehta v. Union of India (2001): It laid down that brick kilns can operate only after a thorough impact assessment on human health and vegetation.

These precedents collectively reinforced the Tribunal’s stance on the stringent regulation of brick kiln operations to protect environmental and public health.

Legal Reasoning

The Tribunal’s legal reasoning hinged on the 'Precautionary Principle,' which mandates that the absence of full scientific certainty should not postpone measures to prevent environmental degradation. The NGT found that Haryana’s extension for adopting Zig-zag Technology lacked a rigorous scientific basis, particularly concerning ambient air quality and the area's capacity to handle additional pollutants. By referencing the Supreme Court's directives, the Tribunal emphasized that any relaxation of environmental norms requires substantial evidence and safeguards, which were absent in the impugned order.

Impact

This judgment has significant implications for future environmental regulation of brick kilns not only in Haryana but across India. It underscores the necessity for:

• Comprehensive scientific studies before altering environmental policies.
• Strict adherence to prescribed environmental norms and technologies.
• Enhanced accountability and data-driven decision-making by regulatory authorities.

Moreover, it reinforces the NGT’s authority to oversee and ensure compliance with environmental standards, potentially influencing stricter regulatory frameworks in other sectors as well.

Precautionary Principle

This principle advocates for proactive action in environmental protection, even if some cause-and-effect relationships are not fully established scientifically. It implies that lack of full certainty should not be a reason for postponing measures that prevent environmental harm.

Carrying Capacity Assessment

This involves evaluating the maximum number of brick kilns that an area can sustain without exceeding its environmental absorbency limits, particularly regarding air quality and soil health.

Zig-zag Technology

A modern brick kiln technology designed to reduce emissions by improving fuel efficiency and minimizing particulate matter release compared to traditional kilns.

FCBTK Technology

Conventional Fuel-Based Technology involving the use of agro-residues as fuel in brick kilns, which is less efficient and more polluting than Zig-zag Technology.

The Dinesh Chahal v. Union Of India judgment serves as a critical reminder of the judiciary's role in upholding environmental standards. By mandating thorough scientific evaluations before permitting environmentally impactful activities, the NGT ensures that developmental activities do not come at the cost of environmental degradation and public health. This case reinforces the necessity for transparent, data-driven policymaking and the enforcement of robust environmental regulations.

Moving forward, stakeholders involved in brick kiln operations must prioritize sustainable technologies and comply with environmental assessments to align with judicial mandates. The judgment not only safeguards the current environmental standards but also sets a precedent for future cases involving environmental conservation and sustainable industrial practices.
