Delhi Government has withdrawn the exclusive facility granted to Maruti dealers to register new vehicles with immediate effect following the Supreme Court's order banning all non-commerical vehicles not complying with Euro-II emission norms in the national capital region (NCR). In a letter sent to the Maruti Udyog Ltd (MUL), the company which has a market share of about 80 per cent in the passenger car segment, the transport department of the Delhi government has asked to stop the registration process immediately, official sources said.
