Case Note & Summary
The Supreme Court was hearing special leave petitions concerning the translocation of hundreds of deer from A.N. Jha Deer Park, Hauz Khas, New Delhi, to wildlife sanctuaries and tiger reserves in Rajasthan and within Delhi. The controversy arose over the management of the deer population and the ecological carrying capacity of the park. In an earlier order dated 26th November 2025, the Court had directed the Central Empowered Committee (CEC) to conduct surveys, assess carrying capacity, inspect release sites, and prepare a comprehensive roadmap for translocation. The CEC submitted a detailed 428-page report on 6th March 2026, which found that the existing enclosure could sustainably accommodate only 38 deer based on Central Zoo Authority (CZA) guidelines, and that translocation of surplus deer to Ramgarh Vishdhari Tiger Reserve and Mukundra Hills Tiger Reserve was scientifically justified and ethically defensible. The CEC also recommended against intra-park or inter-park relocation within Delhi as it would merely shift the problem. The Court considered the CEC report and issued directions including: regulating the enclosure to its carrying capacity of 38 deer, requiring CZA recognition and compliance with its recommendations, implementing remedial measures such as repairing water troughs and constructing night shelters, filling vacant posts, and exploring immunocontraception as a population regulation method. The Court also reiterated its earlier direction prohibiting commercial events in the park and promoting educational outreach. The decision upholds the translocation plan subject to scientific safeguards and emphasizes sustainable management of captive wildlife in urban settings.
Headnote
A) Wildlife Law - Translocation of Captive Deer - Scientific Carrying Capacity - Central Zoo Authority Guidelines, 2008 - The court considered the translocation of spotted deer from an urban deer park to tiger reserves, relying on the CEC report which assessed carrying capacity at 38 deer based on CZA norms. The court held that translocation to ecologically suitable tiger reserves is scientifically justified and ethically defensible, provided it follows statutory safeguards and IUCN Guidelines (Paras 2-4, 17, 52-54). B) Wildlife Law - Carrying Capacity Assessment - Central Zoo Authority Guidelines, 2008 - The CEC applied CZA guidelines prescribing 1,500 sq. metres per pair of spotted deer, resulting in a carrying capacity of 38 deer for the 10.26-acre enclosure. The court accepted this assessment and directed that the enclosure be regulated accordingly (Paras 17, 54). C) Wildlife Law - Immunocontraception as Population Regulation - Wildlife Protection Act, 1972 - The court directed the CZA to engage the Wildlife Institute of India to design a pilot project on immunocontraception for spotted deer at A.N. Jha Deer Park, as a non-invasive method for managing surplus populations (Para 54(x)). D) Wildlife Law - Prohibition of Commercial Events in Ecological Zones - The court directed DDA to refrain from organizing commercial events in A.N. Jha Deer Park and instead develop non-commercial public outreach programmes (Para 3(F)).
Issue of Consideration
Whether the translocation of deer from A.N. Jha Deer Park to tiger reserves is legally and scientifically justified, and what measures are required for the sustainable management of the deer population.
Final Decision
The Court accepted the CEC report and directed that the deer enclosure at A.N. Jha Deer Park be regulated to a carrying capacity of 38 deer, with CZA recognition and compliance. Translocation of surplus deer to Ramgarh Vishdhari Tiger Reserve and Mukundra Hills Tiger Reserve is approved subject to scientific safeguards. DDA must implement remedial measures and explore immunocontraception. Commercial events in the park are prohibited.
