NGT Can Impose Compensation Without Statutory Formula, Guided By Polluter Pays Principle: Supreme Court Upholds Environmental Penalties On Builders

“Project Cost or Turnover Can Be A Valid Yardstick – Law Doesn’t Require Mathematical Formula For Environmental Damage”, In a landmark decision strengthening environmental jurisprudence, the Supreme Court upheld the National Green Tribunal’s power to impose environmental compensation on errant builders even in the absence of a statutory formula, holding that discretion under the NGT Act must be exercised in line with constitutional principles and judicial reasoning.

The Court dismissed two civil appeals filed by real estate developers—M/s. Rhythm County and M/s. Keystone Properties—who had challenged penalties of ₹5 crores and ₹4.47 crores respectively imposed by the NGT for undertaking large-scale construction in Pune without mandatory environmental clearances and continuing operations despite regulatory stop-work orders.

Delivering a detailed 75-page judgment, the Bench comprising Justice Dipankar Datta and Justice Vijay Bishnoi ruled that the NGT is legally empowered to enhance or quantify environmental compensation based on the economic scale of the project, including its cost or turnover, as long as such yardsticks are applied reasonably and proportionately.

No Straightjacket Formula Needed To Enforce Environmental Accountability

The Supreme Court firmly rejected the contention that the NGT lacked jurisdiction to quantify compensation in the absence of codified rules or delegated legislation.

“The appellants’ arguments that the NGT is denuded of authority to quantify compensation in the absence of a legislatively prescribed formula… falters when tested against the plain statutory text,” the Court observed, invoking Sections 15 and 20 of the National Green Tribunal Act, 2010.

The Court reminded that the NGT is guided by broader constitutional principles of environmental justice, especially the ‘polluter pays’, ‘sustainable development’ and ‘precautionary’ principles, all explicitly codified in Section 20 of the NGT Act.

“Environmental compensation must rest on a foundation of rationality, proportionality and reasoned assessment. The NGT’s powers are wide, flexible and principle-oriented.”

The Court held that rigid formulas were neither necessary nor appropriate in the field of environmental regulation, which often requires expert evaluation and flexible remedies tailored to individual cases.

Builders Cannot Claim Immunity Just Because Exact Harm Is Hard To Measure

The judgment addressed an important and recurring defence taken by real estate developers: that unless direct, measurable environmental harm is proven, no compensation can be levied.

“To say that mere violation of the law in not observing the norms would result in degradation of environment would not be correct,” the developers had argued, citing Deepak Nitrite Ltd. v. State of Gujarat.

However, the Court categorically clarified:

“Such a submission is fallacious. Environmental harm is not always measurable in laboratory terms. Violation of mandatory safeguards, especially continued construction without consent-to-establish or operate, itself triggers the application of the ‘polluter pays’ principle.”

The Court emphasised that the scale of operations—i.e., the project's total cost or revenue—could justifiably be taken as a proxy for environmental impact, especially in urban construction zones where the stress on air, water, waste and traffic systems is high.

“Linking scale to impact sends a message that bigger players need to play by greener rules,” the Court said.

CPCB Guidelines Not Binding, But Can Be Used When Applied Rationally

One of the contentious issues in the appeals was the use of Central Pollution Control Board (CPCB) guidelines for computing environmental compensation, which had been employed by the NGT in the Keystone case.

The developers argued that these guidelines were designed for polluting industrial units—not residential projects—and lacked statutory backing.

While accepting that the CPCB formula is not mandatory, the Court held:

“The CPCB framework operates as a facilitative and indicative tool, not a rigid or exhaustive code… The NGT remains empowered to adopt such scientifically informed mechanisms while applying its independent mind.”

The Court distinguished the present case from Benzo Chem Industrial Pvt. Ltd., where the NGT had imposed arbitrary penalties based on unverifiable turnover estimates. In contrast, the current case involved verified material, expert reports, site inspections, and considered hearings.

Judicial Independence and Expert Committees: No Abdication of Adjudicatory Role

Another key issue was whether the NGT had “outsourced” its decision-making to expert committees. The developers alleged that the NGT merely rubber-stamped Joint Committee reports.

The Court decisively rejected this:

“To characterise the NGT’s exercise as abdication would be to conflate reliance on technical assistance with absence of independent application of mind—a proposition that finds no support either in law or on the facts of the present case.”

In Rhythm’s case, the NGT consciously enhanced the recommended compensation from ₹2.39 crores to ₹5 crores based on project cost of ₹335 crores, applying the principle laid down in Goel Ganga Developers v. Union of India, where 5% of project cost was upheld as a general benchmark.

In Keystone’s case, the NGT distinguished between regularised violations and separate infractions of continuing work without consent and occupancy without clearances—awarding ₹4.47 crores using a computation methodology that was transparently reasoned.

Builders Must Bear Responsibility For Breach Of Environmental Norms, Regardless Of Subsequent Regularisation

The Supreme Court was clear that post-facto approvals under violation windows or conditional environmental clearances do not whitewash prior breaches.

In Keystone’s case, although a one-time violation window EC was obtained in 2020, the Court noted:

“Construction without CTE from 2013 to 2020, continuation of work during closure directions, and handover of possession without CTO—these constitute distinct and serious statutory violations.”

The NGT was justified in treating these as independent infractions deserving separate compensation.

Similarly, in Rhythm’s case, despite later compliance and regularisation, the Court noted that construction continued in violation of a stop-work notice, and that clubhouses and buildings had been raised beyond sanctioned limits.

A Resounding Endorsement of NGT’s Role and the Principle of Environmental Accountability

Upholding both NGT orders in full, the Supreme Court held:

“We find no ground to interfere with the impugned computation of environmental compensation in both appeals… The NGT proceeded on contemporaneous material, expert inputs, and applied its independent mind in a manner consistent with the polluter pays principle.”

The Court extended the time for payment of compensation by three months and ordered that parties bear their own costs.

This ruling is expected to have far-reaching consequences in shaping environmental accountability in the real estate and infrastructure sectors and affirms the NGT’s central role in enforcing non-negotiable environmental safeguards.
