A PIL, instituted by the Supreme Court 23 years ago on its own after taking note of a newspaper report 'And Quiet Flows Maili Yamuna', was today transferred to the National Green Tribunal (NGT) on the ground that there cannot be parallel proceedings on the same issue. <br/><br/>A bench of Chief Justice J S Khehar and Justice D Y Chandrachud was apprised of recent orders passed by the NGT with regard to the steps to be taken to clean the Yamuna.<br/><br/>The apex court expressed satisfaction on the orders passed by the green panel on cleaning of the river and said the current matter also fell under the NGT's jurisdiction. <br/><br/>The court, however, said if NGT was confronted with any constitutional or legal issue which it cannot deal with, then Solicitor General Ranjit Kumar, who is assisting the court as an amicus curiae, can file an application before it.<br/><br/>During the hearing, the apex court perused reports filed by the Delhi Jal Board (DJB) on the current status of construction of the Interceptor Sewer Project meant to collect waste water flowing in three major drains, Najafgarh Drain, Supplementary Drain and Shahadra Drain. <br/><br/>
