In the case of New Delhi Nature Society v. Director Horticulture DDA & Ors. (2026), the Supreme Court of India addressed the translocation of hundreds of deer from A.N. Jha Deer Park in Hauz Khas, New Delhi, to wildlife sanctuaries and tiger reserves in Rajasthan and elsewhere in Delhi.
Case Background
The dispute arose following the Central Zoo Authority’s (CZA) decision to cancel the “mini zoo” status of A.N. Jha Deer Park due to persistent non-compliance with management norms and an exponentially increasing deer population that far exceeded the park’s capacity. While some deer had already been moved to tiger reserves in Rajasthan, the petitioner challenged the translocation process as being “unduly harsh” and detrimental to the animals’ welfare.
Findings of the Central Empowered Committee (CEC)
The Court relied heavily on a detailed 428-page report from the CEC, which established several key points:
- Scientific Carrying Capacity: Based on CZA norms, the 10.26-acre enclosure can sustainably and humanely accommodate only 38 spotted deer (15 males and 23 females).
- Ineffectiveness of Urban Relocation: Moving deer to other urban parks within Delhi was rejected as a long-term solution, as it would merely shift management problems rather than resolve the underlying ecological issues.
- Ecological Benefits of Translocation: The CEC found that translocating “captive-managed spoiled deer” into suitable wild landscapes (like tiger reserves) is scientifically justified. Such moves integrate prey species back into the wild, enhance genetic fitness, and help maintain trophic balance through natural predation.
Key Directions of the Supreme Court
The Court accepted the CEC’s recommendations and issued the following mandates:
- Phased Translocation: Surplus deer must be translocated in a time-bound, phased manner to the Mukundara Hills Tiger Reserve (MHTR) and Ramgarh Vishdhari Tiger Reserve (RVTR) in Rajasthan.
- Adherence to Protocols: All translocations must strictly follow “soft-release” protocols, utilizing specialized prey transfer vehicles and institutionalized post-release monitoring to ensure animal welfare.
- Retention of Limited Population: Up to 38 deer may be retained at A.N. Jha Deer Park, subject to obtaining formal CZA recognition and implementing immediate remedial measures, such as repairing water troughs and constructing dedicated night shelters.
- Protection of Forest Status: The Court directed that the status of A.N. Jha Deer Park as a protected forest must not be altered under any circumstances.
- National Guidelines: The Court ordered that the comprehensive guidelines for animal translocation prepared by the CEC be examined by the Ministry of Environment, Forest and Climate Change to be eventually imparted with statutory status.
- Independent Oversight: The Delhi Development Authority (DDA) must constitute an independent advisory committee of experts and civil society members to promote transparency and participatory management of the park.
The matter is scheduled to be listed again on January 19, 2027, to receive a compliance report regarding these directions.
