New Delhi, Nov 22 (IANS): The Supreme Court has declined to interfere with the National Green Tribunal (NGT) order prohibiting use of RO filters in Delhi and instead asked RO manufacturers association to move Centre with their representation before any notification is issued.

A bench headed by Justice Rohinton Nariman declined to stay the NGT order.

The counsel for manufacturers association contended that the NGT has imposed a blanket ban, and RO water is used for many medical purposes especially useful in dialysis.

"RO removes heavy material from water. It is useful in treating contaminated water," said the counsel insisting it has abundant material to support its case.

The court directed the Centre to consider the representation from the association before passing any notification. The association will submit the material within 10 days and directs the government to consider it's representation before passing any notification.
