The Supreme Court on Wednesday refused to grant more time to the Centre for implementing the law to regulate the use of plastic for packaging gutka and other tobacco products. A bench headed by Justice G S Singhvi asked it to notify that within two days. The court referred to its December 2010 order, in which it had directed the Centre to come out with the law within eight weeks which expires on February 4.The apex court was hearing petitions filed by different gutka, pan masala and chewing tobacco manufacturing companies seeking modification of its ruling of banning use of plastic as packaging material for their products by March 1 this year.
