"Rest assured, before the vacation, we will decide the matter," a bench headed by NGT Chairperson Justice Swatanter Kumar said.
The assurance from the NGT came after Sterlite Industries completed their arguments on how Tamil Nadu Pollution Control Board's March 29 order to shut down the plant was passed "without application of mind".
Referring to a recent affidavit filed by the TNPCB in support of its decision to order closure of the plant, Sterlite contended the reasons given by the Board are mere "inferences and suppositions and without any foundation.
The lawyer also questioned the closure order passed by the Chairman of the TNPCB by invoking emergency powers, saying "the power was invoked six days after the complaints were made against the plant".
"What was the emergency that occurred six days after the complaints?," he said.
