Order of the National Green Tribunal in the matter of Vardhaman Kaushik Vs Union of India & Others dated 30/05/2019 regarding registration of BS-IV compliant diesel vehicles.

NGT dismissed the applications quoting its order of 27/07/2018, which said "It has not been brought to our notice that in any order of this Tribunal or the Hon’ble Supreme Court diesel vehicles other than diesel cars/SUVs of 2000 cc capacity and above, even if BSIV compliant, can be unconditionally registered in the NCT. Though Tribunal has made exception in respect of vehicles meant for essential services on ad hoc basis, such exception has not been made across the board."
