JUDGMENT : 1. While reiterating that commercial vehicles which do not comply with the directions issued by this Court on 28th July, 1998, shall not be permitted to ply in Delhi w.e.f. 1st April, 2001, we have today made certain relaxations and exemptions to mitigate the sufferings of commuter public in general and school going children in particular, by granting limited extension of the dead-line till 30th September, 2001, in certain specified cases. 2. With a view to ensure that the relaxations and exemptions given by us today are not abused or misused, we direct that each one of the commercial vehicles (buses or autos) which are covered by the relaxations, shall be permitted-to ply after 1st April, 2001 till 30th September, 2001 only if they carry and display on the windscreen of the concerned vehicle a permit/or authorisation duly signed by Shri Ashok Pradhan, Principal Secretary, Transport, Delhi Administration, Delhi. Shri Pradhan shall issue the permit/authorisation after satisfying himself that the person applying for the permit/authorisation falls within the parameters of relaxation given by us and is entitled to the permit/authorisation, having placed a firm order for conversion to CNG/other clean fuel mode to ply the vehicle in Delhi till 30th September, 2001. Copies of the affidavits to be filed by the parties, on or before 31.3.2001 in this Court, in terms of various clauses of relaxation, shall be furnished to Shri Pradhan by Shri Rawal, the learned A.S.G. for facility of reference. 3. A report shall be submitted to this Court on or before 12th April, 2001 by Shri Pradhan giving details of commercial vehicles to which permits/authorisations have been given. The permit/authorisation shall clearly indicate that the vehicle concerned can ply only upto 30th September, 2001 and not beyond. No commercial vehicle which does not carry the permit/authorisation, signed by Shri Pradhan, shall be permitted to ply in Delhi w.e.f. 1st April, 2001. The Traffic Department and the STA shall ensure strict compliance with this direction. 4. Extensive publicity shall be given to directions (g & f) given on 28.7.1998 and the limited relaxation granted today in certain specified cases both through electronic as well as print media by the Delhi Administration. 5.
