Case at a Glance
A letter petition complained that the Borum River and other rivers around Itanagar were being narrowed by boundary walls, private bridges and unregulated earth mining. A Joint Committee found the complaint genuine: walls extended into the river bed, a private bridge and concrete wall stood downstream, and large-scale earth mining was causing siltation, while Land Possession Certificates were being issued without demarcating river boundaries. The State respondents filed no replies despite repeated opportunities. The National Green Tribunal directed removal of river-bed encroachments after hearing affected persons, a halt to illegal mining, issue of Land Possession Certificates only after river banks are demarcated, and penalty and compensation action by the Pollution Control Board, with an action taken report in six months.
The applicant’s letter petition dated 18 December 2024 alleged encroachment of river beds in Itanagar. Relying on Municipal Corporation of Greater Mumbai v. Ankita Sinha, (2021) 10 SC CK 0034, the Tribunal treated it as an application for suo motu action. On 25 April 2025 the Principal Bench constituted a Joint Committee to inspect the sites, and the case was later transferred to the Eastern Zone Bench at Kolkata.
The Committee inspected the sites on 21–22 June 2025. It found boundary walls extending into the river bed, a private bridge and a concrete wall downstream, and large-scale unregularised earth mining causing siltation. It also noted that Land Possession Certificates had been issued without demarcating river boundaries. The State respondents did not file replies despite several opportunities and an order of costs, and the applicant did not file further material.
The Key Question Before the Court
What must the State and its agencies do when rivers are being narrowed and silted by private encroachments on the river bed and unregulated earth mining?
A Constitutional Duty to Protect Rivers
The Tribunal accepted the Joint Committee’s report, noting that “the issues raised by the petitioner have been genuine” and that “The Borum River bed is being highly encroached by construction of boundary walls by various private parties.” It expressed strong displeasure at the State Pollution Control Board’s inaction, observing that the violations attract the Water (Prevention and Control of Pollution) Act, 1974 and the Environment (Protection) Act, 1986.
Invoking Article 48A, the Tribunal held the State to be “under constitutional obligation to protect and improve environment”. It also recorded: “We express displeasure that despite sufficient time and opportunity granted respondents have not filed responses.” Rather than leaving the matter to the parties, it issued a set of directions addressed to each department responsible for rivers, land records, mining and pollution control.
What the Court Actually Held
- Deputy Commissioners must remove river-bed encroachments, including boundary walls and private bridges, through eviction proceedings after hearing affected persons, and must stop illegal earth mining along the rivers.
- Land Possession Certificates must be issued only after river banks are demarcated; the Chief Secretary must place rules restricting river-bed construction before the State Government.
- The Geology and Mining Department must act against illegal mining and prepare District Survey Reports, SEIAA must ensure prior environmental clearance, and the Water Resources Department must protect the rivers.
- The State Pollution Control Board must ensure consents for mining and file penalty and environmental compensation complaints; a consolidated action taken report is due within six months.
Why This Judgment Matters
- Encroachment and siltation of urban rivers increase flood risk for everyone living downstream.
- Linking land documents to demarcated river boundaries addresses the root cause of river-bed construction.
- It shows that a simple letter petition can trigger effective environmental action before the NGT.
What Should Advocates Take Away From the Judgment?
For Residents and Petitioners
- A letter petition backed by specific facts can be treated as a suo motu application.
- Joint Committee reports can independently verify encroachments and mining.
- Eviction must still follow a hearing of affected persons.
For Counsel
- Rely on Municipal Corporation of Greater Mumbai v. Ankita Sinha on the NGT’s suo motu powers.
- Seek department-wise directions and a time-bound action taken report.
- Press for penalty and compensation complaints under the Water and Environment Acts.
Key Takeaways
- River beds cannot be walled off or bridged privately without lawful sanction.
- Land Possession Certificates only after demarcation of river banks.
- Illegal earth mining must be stopped and penalised.
- Action taken report due within six months.

Conclusion
The order turns a citizen’s letter into a framework for protecting rivers in and around Itanagar, assigning a clear task to each department and demanding a report within six months.
Practical takeaway: Where rivers are being encroached or mined, approach the NGT with specific facts and seek a Joint Committee inspection; department-wise directions with a reporting deadline are achievable.
