Supreme Court today dismissed the plea of auto manufacturers and banned the sale and registration of vehicles with BS-III emission norms. The apex court's move means only cars with BS-IV emission norms can be sold in the country.
The Supreme Court said the health of the people is more important than the commercial interest of automobile companies.
The move is likely to affect the sale of upto 8.5 lakh vehicles in India. Supreme Court's directive comes into effect from April 1.
A bench of Justices Madan B Lokur and Deepak Gupta prohibited registration of any vehicles which do not meet the Bharat Stage-IV emission norm standards from April 1.
