The petitioners have sought that the court direct the Delhi Metro to construct an underground line over 6 km from Lajpat Nagar to Kalkaji on the Central Secretariat-Badarpur section.

The RWAs oppose the elevated stretch citing environmental and safety concerns. They claim that an elevated stretch would lead to increased noise pollution and affect the environment.

The petition has been filed by the E-Block Residents' Welfare Society, the Greater Kailash Society, the Defence Colony Residents' Welfare Association, the Lajpat Nagar-III Neighbourhood Residents' Association and the Kailash Fraternity and Kailash Colony Association.
