The May 2026 cycle in Indian environmental law has produced an operationally consequential cluster — the Supreme Court's Chambal Gharial Sanctuary sand-mining directions on 26 May 2026, the NGT Principal Bench's Sultanpuri illegal tree-felling order, the Jaipur textile CETP operationalisation, the Sijimali bauxite project notice to Vedanta and MoEFCC, the Malbazar hospital bio-medical waste direction, the Waste-to-Energy CPCB compliance report, the pre-monsoon ESZ enforcement pattern, the CAQM 50 mg/Nm³ PM emission standard for Delhi-NCR, the Environmental (Protection) Fund Rules 2026, and the continuing T.N. Godavarman engagement on deemed-forest doctrine. A practitioner's read on the cycle.
On 21 April 2014 a three-judge bench of Justices A.K. Patnaik, Surinder Singh Nijjar and Fakkir Mohamed Ibrahim Kalifulla — with Patnaik J. pronouncing judgment — held that every iron-ore and manganese-ore mining lease in Goa had, in its renewed avatar, expired on 22 November 2007; that every mining operation thereafter was illegal; that the State's 'second renewal' orders had no statutory basis; and, drawing on the Justice M.B. Shah Commission Report, translated inter-generational equity into a financial mechanism by capping iron-ore excavation at 20 million MT a year, mandating e-auction of inventorised ores, and constituting the Goan Iron Ore Permanent Fund under Court supervision.
On 29 March 2019 a two-judge bench of Justices D.Y. Chandrachud and Hemant Gupta suspended — not outright quashed — the 28 October 2015 environmental clearance for the Mopa greenfield airport in Goa, and remitted the matter to the Expert Appraisal Committee for re-examination within a month, on a record that disclosed non-disclosure in Form-1 of ecologically sensitive markers, an inadequate cumulative-impact assessment, and faunal markers including the South Asian river dolphin that the EAC's recommendation had not engaged. A practitioner's read on the duty of candour, the EIA rigour standard, and the suspension-for-re-examination remedial template.
On 13 February 1996 — six months before *Vellore* — a Division Bench of the Supreme Court led by Justice B.P. Jeevan Reddy applied the absolute-liability doctrine of *Oleum Gas Leak* to five chemical units at Bichhri village in Rajasthan and operationalised the polluter-pays principle as a remediation-cost obligation. The judgment is doctrinally the antecedent to *Vellore* on polluter-pays, the first explicit reception of customary international environmental law into Indian law, and — in its 2011 execution arc — confirmed recovery of ₹37.385 crore plus interest from the polluters.
On 6 July 2011, a three-judge Bench of Chief Justice S.H. Kapadia, Justice Aftab Alam and Justice K.S. Panicker Radhakrishnan — within the T.N. Godavarman writ — dismissed the Shella Action Committee's challenge and upheld the revised environmental clearance, site clearance and Stage-I forest clearance granted to Lafarge for its limestone mine at Nongtrai, East Khasi Hills, Meghalaya. Part II of the judgment used the occasion to issue forward-looking guidelines under section 3(3) of the Environment (Protection) Act, 1986 — directing the appointment of a National Regulator, the expansion of Regional Offices, the constitution of Regional Empowered Committees, GIS-based decision-support databases, the sequencing of forest clearance before environmental clearance, and mandatory public hearing. A digest of the doctrinal architecture, the doctrine of proportionality, the anti-'fait accompli' principle, and the implementation record fifteen years on.
On 13 December 1996, taking suo motu cognisance of a press report on a Himachal motel that had encroached on protected forest land and diverted the Beas, a Division Bench of the Supreme Court formally received the Public Trust Doctrine into Indian law — quashing the prior approvals and lease, ordering restitution at the motel's cost and issuing show-cause on exemplary damages. A digest of the doctrine, why the Court read it into Articles 21 and 48A, and how it has since travelled from rivers and forests to spectrum and coal.
On 30 December 1996 — the penultimate working day before his retirement — Justice Kuldip Singh, sitting with Justice Faizan Uddin, delivered the Taj Trapezium judgment: 292 enumerated industries within a 10,400 square kilometre polygon around the Taj Mahal were directed to switch to natural gas or relocate outside the Zone, with labour-protective relief for workers in relocated units. A digest of how the Bench operationalised the *Vellore* principles, why it created a monument-centric zoning template, and how the continuing-mandamus device powered later orders from CNG-Delhi to subsequent TTZ rulings.
On 18 October 2000, a three-judge Bench of Chief Justice Dr A.S. Anand, Justice S.P. Bharucha and Justice B.N. Kirpal — by a 2:1 majority — allowed the construction of the Sardar Sarovar Dam to continue, subject to the condition that the dam height be raised in 5-metre slabs only after the Relief and Rehabilitation Sub-Group of the Narmada Control Authority certified that R&R for displaced families had been carried out pari passu with construction. The majority articulated a doctrine of narrow judicial review in major-project PILs, held the Narmada Water Disputes Tribunal Award binding, and treated sustainable development as a balancing exercise. Justice Bharucha dissented. A digest of the holding, the bench's reasoning, the dissent treated as the moral compass of environmental PILs, and the subsequent doctrinal arc.
On 9 January 1991, a Division Bench of the Supreme Court — Justices K.N. Singh and N.D. Ojha — articulated the right to enjoyment of pollution-free water and air as part of the right to life under Article 21, and held that PIL standing in environmental matters does not require a personal-injury showing. On the facts the petition was dismissed as not bona fide and ₹5,000 costs imposed, but the legal principles — though technically obiter — have been treated as authoritative in every subsequent environmental Article 21 case.
On 12 December 1996, a two-judge Bench of Justice J.S. Verma and Justice B.N. Kirpal in W.P.(C) 202/1995 held that the word 'forest' in the Forest (Conservation) Act, 1980 must be understood according to its dictionary meaning, irrespective of ownership or classification. The order constituted State Expert Committees, imposed felling moratoriums in the Northeast, J&K and other hill regions, protected workers in closed saw mills, and — through the formula 'this order is to continue, until further orders' — inaugurated what has become the longest-running environmental public interest litigation in Indian history. A digest of the foundational order, the 'deemed forest' doctrine, the subsequent architecture (CEC came in 2002, not 1996), and the doctrine's continuing engagement through 2026.
On 16 May 2025, a Supreme Court bench of Justices A.S. Oka and Ujjal Bhuyan struck down the 2017 Notification and the 2021 Office Memorandum that had enabled ex post facto environmental clearances, holding that retrospective approval was foreign to the architecture of Indian environmental regulation. On 18 November 2025, a different bench led by Chief Justice B.R. Gavai — sitting with Justice K. Vinod Chandran and Justice Bhuyan — recalled that judgment by 2:1, with Bhuyan J. now in dissent. A digest of both judgments, the doctrinal disagreement, and what the environmental-clearance architecture now looks like.
