Mandatory compliance with carrying capacity and scientific translocation protocols for captive wildlife in urban ecological zones.

In brief

The question

1. Whether the translocation of surplus deer from A.N. Jha Deer Park to wildlife reserves is legally and ecologically justified

The court held

The Supreme Court affirmed the Delhi High Court’s orders and accepted all CEC recommendations. It held that the DDA may retain only up to 38 deer (15 males, 23 females) at A.N. Jha Deer Park, provided it obtains fresh CZA approval and upgrades its infrastructure

It also directed

The surplus population must be translocated in a phased manner under CEC supervision, utilizing "soft-release" protocols and specialized prey transfer vehicles. The court further directed that the park area remain a "protected forest" in perpetuity and that the CEC's draft guidelines on animal translocation be granted statutory status by the Ministry of Environment, Forest and Climate Change within six months

01Facts

The dispute concerns the translocation of hundreds of deer from A.N. Jha Deer Park, Hauz Khas, to wildlife sanctuaries in Rajasthan and New Delhi

¶ 2

The Central Zoo Authority (CZA) cancelled the park’s "mini zoo" status in 2021 due to persistent non-compliance with management norms and exponential population growth

¶ 5

While the Delhi High Court initially permitted translocation in July 2024 based on a DDA affidavit proposing the retention of two dozen deer, the Petitioner challenged this, arguing that the deer should remain in expanded local enclosures

¶ 6, 8

On November 26, 2025, the Supreme Court stayed further translocation and directed the Central Empowered Committee (CEC) to conduct a carrying-capacity study

¶ 3

The CEC's 2026 report recommended a scientifically managed translocation of the surplus population, retaining only a small, specific number of deer under strict guidelines

¶ 4

02Issues

i.1. Whether the translocation of surplus deer from A.N. Jha Deer Park to wildlife reserves is legally and ecologically justified

¶ 5, 9

ii.2. Whether the park possesses the ecological carrying capacity to sustain the current deer population without translocation

¶ 4 (CEC Recommendation 17), 9

iii.3. Whether the DDA can legally maintain deer at the site following the cancellation of its "mini zoo" recognition by the CZA

¶ 5, 9

03Law Applied

Section 38H(6) of the Wild Life (Protection) Act, 1972, regarding the cancellation of recognition for zoos

¶ 5

Guidelines for Establishment and Scientific Management of Zoos in India, 2008, issued by the Central Zoo Authority, specifically regarding space requirements (1,500 sq. meters per pair of spotted deer) and optimal sex ratios

¶ 4 (CEC Recommendation 17)

IUCN Guidelines for Reintroductions and Other Conservation Translocations

¶ 3 (Direction C), 4 (CEC Recommendation 53)

Provisions in the judgment · 1

Wild Life (Protection) Act, 1972 Section 38H

04Reasoning

The court reasoned that since the CZA recognition had expired and been cancelled, the continued retention of the entire deer population at the park was "impermissible in law" as there was no statutory authority to manage them

¶ 5

Based on the CEC’s scientific assessment, the park’s usable area of 29,000 sq. meters can only sustainably accommodate 38 deer (19 pairs), whereas the current population had increased "exponentially" beyond this carrying capacity

¶ 4, 5

The court rejected the Petitioner's suggestion of intra-park relocation, agreeing with the CEC that shifting deer to other urban parks would merely "transfer the problem" without addressing staffing, veterinary, or habitat deficiencies

¶ 4 (CEC Recommendation 20)

The court emphasized that as a wildlife species, deer should not be confined to restrictive enclosures without compelling ecological justification

¶ 9

It concluded that scientifically managed translocation to tiger reserves—where deer can integrate into the wild and contribute to the trophic balance—was ethically and legally defensible
