NEW DELHI NATURE SOCIETY THROUGH VERHAEN KHANNA V. DIRECTOR HORTICULTURE DDA & ORS. 2025 INSC 1358:

DATE: 26/11/2025

COURT: Supreme Court of India

BENCH: Justice Vikram Nath and Justice Sandeep Mehta

FACTS:

The A.N. Jha Deer Park, established in 1968 by the Delhi Development Authority (DDA) within Hauz Khas Park, South Delhi, serves as one of the capital’s few urban settings for viewing chital/spotted deer in a semi-natural environment. Over the years, it evolved into a significant ecological and recreational space, attracting diverse wildlife and public visitors. The DDA operated the park under a license from the Central Zoo Authority (CZA), which monitors zoos under the Wild Life (Protection) Act, 1972. The CZA had previously cancelled and reinstated the DDA’s license due to mismanagement and non-compliance with zoo guidelines, including failure to control the deer population and maintain veterinary oversight. By 2021, the park was minimally staffed, and the license had expired. The DDA then proposed translocating approximately 550-600 deer to designated wildlife sanctuaries in Rajasthan and Delhi, which the Rajasthan Wildlife Department and CZA reviewed, imposing welfare safeguards in line with IUCN guidelines. On 8th June 2023, the CZA cancelled the park’s recognition and approved the translocation, citing persistent non-compliance and administrative incapacity.

Aggrieved, an NGO petitioned the Delhi High Court via a public interest litigation, seeking to ensure the translocation complied with CZA and IUCN guidelines and that vulnerable deer, such as pregnant or antlered animals, were not moved. The High Court, noting potential risks to the deer and the need for public viewing, stayed the translocation in December 2023. Subsequently, the DDA submitted an affidavit in July 2024 agreeing to retain approximately two dozen deer at the park, subject to renewal of its mini-zoo status, and to translocate the remaining deer in accordance with guidelines. Satisfied with this assurance, the High Court disposed of the writ petition, allowing the DDA to resume translocation under the stated conditions. A subsequent application seeking to recall this order was dismissed in January 2025, which forms the basis of the present special leave petitions challenging the High Court’s orders.

ISSUES:

The core issues before the Court were whether the cancellation of recognition of A.N. Jha Deer Park (Hauz Khas, Delhi) and the approval of translocation of its deer population constituted a lawful exercise of authority under Wild Life (Protection) Act, 1972 and whether the translocation had been carried out in compliance with statutory and conservation standards (including guidelines of Central Zoo Authority (CZA) and international norms such as those of International Union for Conservation of Nature (IUCN)). Additional concerns included whether the authorities failed to record adequate reasons for cancellation of license as required under the statute, and whether vulnerable animals (pregnant deer, juveniles, antlered males) were moved in violation of welfare safeguards, exposing them to ecological and welfare risk.

JUDGEMENT WITH REASONING:

The Court held that given the chronic mismanagement and repeated non-compliance by the managing authority, the decision to cancel the zoo status of A.N. Jha Deer Park and to propose scientific translocation of the deer population was justified. However, the Court required that further translocation be suspended for the time being. It directed the constitution of a fact-finding and expert committee, the Central Empowered Committee (CEC) to conduct an independent, scientific on-ground survey of the Deer Park and of the release sites, and submit a detailed report within eight weeks before any further deer movement is allowed.

The Court recognized that over many years, the Deer Park suffered from severe institutional and infrastructural failures: inadequate veterinary care, lack of enclosure maintenance, absence of systematic population control, and overpopulation far exceeding the carrying capacity of the limited enclosure. These persistent deficiencies meant that the Park operated “far below statutory standards” under the Wild Life (Protection) Act, the National Zoo Policy and the Zoo-management guidelines. The overcrowding of ungulate species in confined spaces is scientifically known to increase stress, risk disease, impair welfare, and violate accepted norms of captive wildlife management. Given that the DDA lacked the requisite resources veterinary staff, fodder, enclosure design, and wildlife-management capacity, the Court concluded that retention of the entire deer population in that small urban enclosure would lead to animal suffering, ecological imbalance, and was therefore not tenable. Under these circumstances, scientifically managed translocation was not only foreseeable, but necessary. The Court observed that the longstanding mismanagement, reiterated non-compliance, and the absence of corrective capacity justified derecognition and relocation, at least in principle.

At the same time, the Court was conscious of the significant welfare, ecological and procedural concerns raised by the petitioner-Society regarding the translocation already undertaken especially relating to vulnerable deer (pregnant females, juveniles, antlered males), lack of pre-relocation health screening, absence of tagging or tracking, neglect of release-site ecological suitability, and reportedly inhumane transportation practices. Because these aspects strike at the heart of accepted conservation ethics and legal standards for wildlife transfers (as per CZA and IUCN norms), the Court ruled that no further translocation should proceed until an independent, scientifically grounded assessment is carried out. By constituting the CEC, the Court mandated a full audit: current deer population, ecological carrying capacity of the Park, suitability and preparedness of release sites, health and welfare status, and a detailed future translocation protocol including tagging, veterinary checks, post-release monitoring, ecological viability studies, and humane transport. This requirement ensures that any future decision balances administrative convenience with constitutional commitments (like the right to a clean environment under Article 21 and duties under Articles 48A/51A(g)) and prioritises animal welfare and ecological integrity.

ANALYSIS:

This case presents an important conflict between administrative convenience in managing wildlife within an urban environment and the legal-ecological obligation to ensure humane, scientifically sound conservation practices. The Supreme Court noted that the Deer Park had long suffered systemic failures overcrowding, insufficient veterinary and infrastructural support, and lack of scientific population control, leading to consistent non-compliance with statutory zoo-management standards. Given these conditions, cancellation of zoo recognition and translocation of surplus deer was not arbitrary but borne out of prolonged managerial incapacity. At the same time, the Court acknowledged that urban ecological spaces like the Deer Park serve a crucial public function, offering nature-based recreation and citizen exposure to wildlife. Thus, merely relocating the animals without ensuring continued ecological integrity and public access could undermine the broader purpose such spaces serve.

The Court adopted a balanced approach by preserving the administrative decision while insisting on accountability and scientific verification before further action. By directing the Central Empowered Committee to ascertain true herd size, carrying capacity, and survival outcomes at relocation sites, the Court intervened to correct procedural gaps that could have led to ecological harm. The insistence on welfare-compliant methodology tagging, health assessment, humane transport, and post-release monitoring, reflects judicial reinforcement of India's constitutional environmental commitments and international conservation norms. The judgment therefore aligns wildlife-management decisions with a rule-based, transparent, and science-driven process, ensuring that future translocation protects both ecological equilibrium and animal well-being rather than merely resolving administrative burden.
