Introduction

The Supreme Court of India, in the landmark case M.C. Mehta Petitioner(S) v. Union Of India (S). (2018 INSC 982), addressed the critical issue of enforcing Bharat Stage VI (BS-VI) emission norms for motor vehicles. The case primarily revolved around whether BS-IV compliant vehicles could continue to be sold in India beyond the stipulated deadline of March 31, 2020. This commentary delves into the background of the case, the key issues at stake, the parties involved, and the broader implications of the Court's decision.

Summary of the Judgment

On October 24, 2018, the Supreme Court of India delivered a decisive judgment mandating that no motor vehicle conforming to the Bharat Stage IV (BS-IV) emission standards would be permitted for sale or registration across the country effective from April 1, 2020. The Court emphasized the urgency of addressing vehicular pollution to safeguard public health, thereby overruling the automobile manufacturers' requests for an extension to sell existing BS-IV compliant vehicles.

Analysis

Precedents Cited

The Court extensively referenced previous judgments that underscore the constitutional mandate to ensure a clean environment as part of the fundamental right to life under Article 21 of the Indian Constitution.

• 1990 AIR 630 SC: Recognized the right to a decent environment as part of the right to life.
• 1998 2 SCC 601: Affirmed the inclusion of the right to live in a clean environment within Article 21.
• 2004 9 SCC 362: Declared the right to a clean environment as a fundamental right.

These precedents collectively reinforced the Court's stance that environmental protection is integral to the right to life, thereby justifying stringent emission norms.

Legal Reasoning

The Court balanced the government's environmental obligations against the automobile industry's concerns regarding the transition to BS-VI norms. Key aspects of the Court's legal reasoning include:

• Public Health Priority: Emphasized that the health of millions outweighs the financial interests of manufacturers.
• Uniform Enforcement: Argued against region-wise implementation, advocating for nationwide consistency to prevent pollution hotspots.
• Technological Feasibility: Highlighted that manufacturers possess the necessary technology to comply with BS-VI standards, as evidenced by ongoing production of compliant vehicles for export.
• Constitutional Mandate: Cited Article 21, asserting that environmental rights are an extension of the right to life and liberty.

The Court also critiqued the vague language of sub-rule 21 of Rule 115, which allowed limited extensions for vehicle registration, deeming it insufficient for addressing the urgent pollution crisis.

Impact

The judgment has far-reaching implications for various stakeholders:

• Automobile Industry: Mandates a swift transition to BS-VI compliant vehicles, potentially increasing manufacturing costs but aligning with global standards.
• Environmental Policy: Strengthens the enforcement of emission norms, setting a precedent for future environmental regulations.
• Public Health: Anticipates significant reductions in air pollutants, contributing to better respiratory health and overall well-being of citizens.
• Legal Framework: Reinforces the judiciary's role in upholding constitutional environmental rights over economic considerations.

Future cases involving environmental regulations will likely draw on the principles established in this judgment, emphasizing the judiciary's commitment to a sustainable and healthy environment.
