In an order that would speed up construction work of Indian Railways and metro rail in various cities, Supreme Court today stayed an order of National Green Tribunal directing them to seek prior environmental clearances (ECs) for their projects like dedicated freight corridor.<br/><br/>The bench, comprising Chief Justice T S Thakur and Justice A M Khanwilkar, was hearing pleas filed by Dedicated Freight<br/>Corridor Corporation of India Ltd (DFCCIL) and the Metro Rail<br/>against the order passed by the green tribunal that they are<br/>required to seek ECs for all their projects.<br/><br/>Earlier too, the MoEF had told the tribunal that Railways<br/>and Metro Rail projects were not within the purview of the<br/>2006 Environmental Impact Assessment Notification and<br/>therefore prior EC was not required.
