The National Green Tribunal (NGT) in December 2018 had ordered the opening of the plant known as Sterlite Copper. Speaking to reporters here Shanmugam said: "The Tamil Nadu government had argued before the Supreme Court that the NGT does not have jurisdiction in deciding on the government's closure order. "It is a victory for the Tamil Nadu government. The state government will face the case if the company approaches the High Court for relief.

"The Tamil Nadu government had ordered the closure of Sterlite Copper following protests in Thoothukudi in which 13 people died and several others got injured in police firing after the protest turned violent in May 2018. The Tamil Nadu Pollution Control Board (TNPCB) had rejected the company's application to renew its "consent to operate".On an appeal by Vedanta, the NGT set aside the Tamil Nadu government's order to close the plant and ordered TNPCB to issue the renewal of consent to the company within three weeks.
