A bench headed by NGT Chairperson Justice Swatanter Kumar also gave four weeks time as last opportunity to UP government to comply with its directions and listed the matter for further hearing on October 23.
"We had directed all the authorities concerned to take a clear stand as to what is the flood plain area declared by them and whether any construction was permitted or otherwise specifically prohibited. Despite the clear directions, none of the parties, i.E., the local authority, corporation, state of UP, state of Haryana, DDA, and Noida authority as well, have filed such affidavits.
On May 20, the NGT had ordered demolition of all illegal and unauthorised structures in the flood plains of the Yamuna and the Hindon in Delhi, Haryana and Uttar Pradesh on a plea against the 'concretisation' of the banks of the two rivers.
The NGT's directions had come on a plea by UP-based water conservationist Akash Vashishtha claiming construction of concrete farmhouses, plots, colonies and commercial set-ups in river-bed area damages the natural environment and is a grave hazard to well-being of humans and violates the Environment Protection Act 1986.
