 Translocation of captive deer to ecologically suitable reserves upheld as a scientifically justified and legally compliant conservation measure.



Facts

Challenge to translocation of deer from urban park

The case concerned the translocation of a large population of deer from A.N. Jha Deer Park, Hauz Khas, Delhi, to wildlife reserves in Rajasthan and elsewhere. The petitioner opposed translocation, arguing that expansion within the park could accommodate the population.

The Central Empowered Committee (CEC), pursuant to earlier Supreme Court directions, submitted a detailed report assessing carrying capacity, habitat conditions, and feasibility of translocation. The report found that the park could sustainably support only about 38 deer and that excess population required relocation.

The Central Zoo Authority had cancelled the park’s “mini zoo” recognition due to non-compliance and expiry of licence, rendering continued retention legally impermissible.


Issues Framed

Whether the decision to translocate deer from A.N. Jha Deer Park to wildlife reserves was legally and scientifically justified.


Court’s Reasoning

(a) Carrying capacity and statutory compliance
The Court relied heavily on the CEC report, which determined that the enclosure could “sustainably accommodate approximately 38 deer” (Para 4). The park’s loss of recognition under s. 38H(6) Wild Life (Protection) Act, 1972 made continued large-scale retention unlawful.

(b) Scientific basis of translocation
The Court accepted the CEC’s finding that translocation to suitable reserves is “scientifically justified, ethically defensible, and consistent with… statutory framework” (Para 4). It emphasized that wildlife management must align with ecological principles and international norms (IUCN Guidelines).

(c) Rejection of intra-park expansion argument
The contention that additional land could be used was rejected. The Court noted that mere relocation within urban parks would “shift, rather than resolve” management issues (Para 4). Without improvements in habitat and infrastructure, such measures were unsustainable.

(d) Animal welfare and ecological integration
The Court observed that captive deer should not remain confined in restrictive enclosures without compelling justification. Natural predation post-translocation was recognised as part of “ecological integration” and not an adverse consequence.

(e) Deference to expert body (CEC)
The Court treated the CEC as an expert body and accepted its recommendations in toto, noting that its findings reflected scientific assessment and ground realities.


Held

The Court upheld the translocation policy, accepted the CEC recommendations, and directed phased relocation of surplus deer under strict scientific protocols, permitting retention of up to 38 deer subject to regulatory approval.


Ratio

Where expert assessment establishes limited carrying capacity and statutory non-compliance, translocation of wildlife to suitable natural habitats in accordance with scientific and regulatory guidelines is a valid conservation measure
