A Supreme Court division bench has reverted one of its order passed in 1996, which stipulated that brick kilns causing air pollution due to the use of fly ash technology should be relocated and the land on which these kilns were located should be surrendered. "It is still a dispute that prior to the passing of the order no notice was issued to the owners of the land were the kilns were located,' the court stated. It further added that to issue an order without hearing the affected parties was a violation of the principle of natural justice. The 1996 order was passed in response to a petition filed by MC Mehta, an environmental lawyer.
