SC Restricts Retrospective Environmental Clearances

Subject: Polity & Governance | Environment 

Why in News?

• The Supreme Court has quashed the 2021 Office Memorandum (OM) issued by the Union Government.
• The OM permitted ex post facto (retrospective) Environmental Clearance (EC) for projects that had commenced operations without obtaining prior Environmental Clearance.
• The judgment will operate prospectively, meaning future cases will be governed by the ruling, while existing clearances remain unaffected unless separately challenged.

What is Environmental Clearance (EC)?

Environmental Clearance (EC) is the statutory approval required before commencing specified development projects to assess and mitigate their environmental impacts.

Objective

• Assess likely environmental impacts.
• Prescribe mitigation measures.
• Ensure environmentally sustainable development.

Legal Basis

• Environment (Protection) Act, 1986
• Environmental Impact Assessment (EIA) Notification, 2006

What was the 2021 Office Memorandum (OM)?

The 2021 Office Memorandum introduced a mechanism for granting ex post facto (retrospective) Environmental Clearance to projects that had already begun operations without obtaining prior EC.

Key Features

• Allowed defaulting projects to regularise violations after commencement.
• Environmental violations could be regularised upon payment of compensation.
• Effectively created a permanent route for obtaining Environmental Clearance after violating the law.

The Supreme Court held that the OM established a parallel environmental clearance mechanism, contrary to the EIA framework.

Key Findings of the Supreme Court

1. Administrative Instructions Cannot Override Law

The Court held that:

• The 2021 OM was merely an administrative instruction.
• It substantially modified the Environmental Clearance regime established under the EIA Notification, 2006, which is delegated legislation.

Principle

Administrative instructions cannot amend, override, or replace delegated legislation.

2. Prior Environmental Clearance is Mandatory

The Supreme Court reaffirmed that prior Environmental Clearance is a mandatory legal requirement before commencing specified projects.

Applicable Sectors

• Highways
• Airports
• Mining
• Real estate
• Township development
• Resource extraction
• Other notified development projects

3. Ex Post Facto Clearance Cannot Become a Permanent Mechanism

The Court ruled that retrospective environmental clearance cannot function as a regular alternative to obtaining prior approval.

If any amnesty mechanism is introduced, it must:

• Be temporary and exceptional.
• Apply only to a limited class of deserving projects.
• Be justified by overriding public interest.

4. “Pollute and Then Pay” Principle Rejected

The Court criticised the OM for allowing environmental violations to be regularised merely by payment of compensation.

According to the Court, this approach:

• Encourages non-compliance.
• Weakens environmental governance.
• Violates the principle of Sustainable Development.

5. Restriction on Executive Powers

The Central Government cannot issue future administrative orders permitting ex post facto Environmental Clearances.

Any change in the Environmental Clearance framework must be made only through the prescribed legal and statutory process.

Role of Article 142

The judgment clarified that:

• The Supreme Court may still grant appropriate relief in exceptional cases under Article 142 of the Constitution.
• This extraordinary power is exclusive to the Supreme Court and cannot be exercised by the Executive.

Prospective Operation of the Judgment

The ruling applies prospectively.

Meaning

• Future projects must strictly comply with the requirement of obtaining prior Environmental Clearance.
• Existing projects already granted clearance under the 2021 Office Memorandum are not automatically invalidated.

This prevents disruption of major infrastructure and public utility projects.

Status of Earlier Environmental Clearances

The Court clarified that:

• Environmental Clearances granted under the 2017 One-Time Amnesty Notification and the 2021 Office Memorandum continue to remain valid.
• Such clearances may still be challenged individually before a competent court.

Environmental Principles Reinforced

1. Precautionary Principle

Environmental damage should be anticipated and prevented before it occurs rather than remedied later.

2. Sustainable Development

Economic development must proceed in a manner that balances:

• Economic growth
• Environmental protection
• Inter-generational equity

Significance of the Judgment

• Reinforces the mandatory nature of prior Environmental Clearance.
• Upholds the rule of law by preventing administrative dilution of statutory safeguards.
• Strengthens environmental governance and regulatory compliance.
• Prevents the creation of a permanent “regularisation” route for environmental violations.
• Reaffirms the constitutional role of the judiciary in protecting environmental rights.
