The Supreme Court (SC) has banned plying of all 15-year-old motor commercial vehicles including buses, taxis and auto-rickshaws in the National Capital Territory (NCR) from October 2 this year. The SC has expressed concern and distress at the apathy of the authorities concerned in implementing various directions issued by it from time to time. A three-judge bench, comprising justice A S Artand, justice B N Kripal and justice V N Khare, also directed the Union petroleum ministry to take effective steps to eliminate supply of leaded petrol in the NCR by September 30 this year.
