Centre has sought the Supreme Court's permission to review existing guidelines for conservation of tigers in the wake of its order banning tourism in core areas of tiger reserves across the country. Citing concerns expressed by the States, Centre's affidavit virtually urged the apex court to review its July 24 interim order banning tourism in the core areas of the wild cats until final orders.

It claimed that the ban on tourism could result in not only loss of livelihood to several persons but also pose threat to wildlife and forests in the country.
