Judgement of the Delhi High Court in the matter of Shweta Kapoor & Others Vs The Govt of NCT of Delhi & Others dated 11/01/2016. The Notification dated 28.12.2015 issued by the Transport Department, Government of NCT of Delhi prohibiting plying of non-transport four wheeled vehicles in the area of National Capital Territory of Delhi on alternate days on the basis of registration numbers of the vehicles is the subject matter of this batch of writ petitions filed by way of Public Interest Litigation.

The Delhi government's move to allow only alternate use of cars with odd and even registration numbers from 1 January 2016 is a step in the right direction. However, even as such command and control measures will be difficult to sustain, the gains made from these measures will only wane over time. Long-term measures with strong economic incentives to ensure favourable outcomes are imperative for better quality of air and environment. This involves strengthening public transportation systems.
