Why apex court's wading into Darbhanga's ponds
The Supreme Court agreed to hear a case concerning alleged encroachment of three historic water bodies in Darbhanga, Bihar — the interconnected Gangasagar, Dighi and Harahi ponds
A bench issued notice to the concerned authorities on a writ petition filed by an organisation working for pond restoration, seeking responses on allegations of systematic filling and encroachment
Petitioners contend that a beautification project undertaken by state authorities amounts to encroachment disguised as development, while local residents argue for restoration to the ponds' original boundaries
The case is linked to a prior National Green Tribunal order concerning protection of the same water bodies and highlights a broader, decades-long decline in Bihar's traditional water bodies
The Public Trust Doctrine and Article 21
The Public Trust Doctrine holds that certain natural resources — rivers, water bodies, forests, seashores and the air — are held by the State in trust for the free and unimpeded use of the general public, and cannot be granted away or diverted for private/commercial purposes without justification. The doctrine was formally read into Indian constitutional law by the Supreme Court, which has since extended its protection of the right to a healthy environment (part of the right to life under Article 21) to encompass water bodies, including artificial or man-made ones created from natural resources.
Key Details
- The doctrine was enunciated in M.C. Mehta v. Kamal Nath (1997) 1 SCC 388, arising from the diversion of the river Beas for a resort project; the Court held such resources are held in trusteeship by the government and ordered restoration of the river's natural course
- The Court has grounded the doctrine in Articles 48A (State's duty to protect and improve the environment) and 51A(g) (citizens' fundamental duty to protect the environment), read together with the Article 21 right to life
- In October 2025, the Supreme Court held that the Public Trust Doctrine extends to man-made lakes/waterbodies that serve ecological functions, not just naturally occurring ones — reinforcing that their protection is integral to Article 21
The Darbhanga case tests whether a state-run "beautification" project on historic ponds violates the State's trustee obligation under this doctrine — the same constitutional framework (Articles 21, 48A, 51A(g)) the Court has invoked to protect other encroached water bodies.
National Green Tribunal (NGT) and Overlapping Jurisdiction on Water Body Protection
The National Green Tribunal, established under the National Green Tribunal Act, 2010, has original and appellate jurisdiction over substantial questions relating to the environment, including enforcement of legal rights connected to the environment. NGT benches have repeatedly passed orders directing state governments to remove encroachments from wetlands, ponds and other water bodies and restore them to their notified boundaries.
Key Details
- The NGT Act, 2010 created the Tribunal as a specialised body (replacing the National Environment Appellate Authority) to dispose of environmental cases speedily, alongside civil courts
- NGT orders on water body protection typically direct state Water/Land Revenue departments and local urban bodies to survey, demarcate and restore encroached water bodies, and can impose environmental compensation
- Where NGT directions on a specific site are alleged to be unimplemented or undermined by a subsequent state project, affected parties may separately approach the Supreme Court under Article 32 (writ jurisdiction) for enforcement of fundamental rights
The Darbhanga litigation follows an earlier NGT order on protecting these ponds; the Supreme Court petition alleges continuing non-compliance and additionally challenges a new state "beautification" project, illustrating how NGT and constitutional writ jurisdiction can both be invoked over the same water bodies.
Wetlands and Water Body Governance Framework in India
Beyond judicial doctrine, India has a dedicated regulatory framework for wetlands, though traditional urban/peri-urban ponds like those in Darbhanga are frequently outside formal Ramsar or notified-wetland status and rely instead on general environmental law and revenue records for protection.
Key Details
- The Wetlands (Conservation and Management) Rules, 2017 (framed under the Environment (Protection) Act, 1986) govern identification, notification and regulation of activities in wetlands, implemented through State Wetland Authorities
- Ponds not formally notified as "wetlands" typically remain protected only through municipal/revenue records classifying the land as a water body (talab/pokhar), making them more vulnerable to reclassification and encroachment
- Urban pond decline in Bihar mirrors a national pattern of shrinking traditional water bodies due to siltation, solid waste dumping, and construction pressure, prompting repeated judicial and tribunal intervention
The case highlights the vulnerability of historically significant but not formally notified water bodies to encroachment pressure, and the resulting reliance on judicial doctrine (rather than a wetlands notification) for protection.
- Three ponds at issue: Gangasagar, Dighi and Harahi, located in Darbhanga, Bihar, and traditionally interconnected across roughly 1.8 km
- The ponds are estimated to be several centuries old (widely cited as 200–900 years old across sources), forming part of the region's historical and cultural heritage
- Public Trust Doctrine origin case: M.C. Mehta v. Kamal Nath, (1997) 1 SCC 388
- Constitutional basis invoked: Article 21 (right to life, extended to healthy environment), Article 48A (State's duty), Article 51A(g) (citizen's duty)
- NGT established under the National Green Tribunal Act, 2010
- Public Trust Doctrine extended to man-made waterbodies by the Supreme Court in October 2025
