ORDER : 1. On 23rd September, 1986 this Court inter alia directed "Delhi Administration (respondent No. 2) will file affidavit within two weeks from today specifying what steps are being taken for controlling pollution as emission of smoke, noise etc. from vehicles plying in Delhi. Notice to this effect will go to the Delhi Administration immediately." On 25th September, 1986, notice was issued from this Court, and we have no reason to believe that such notice has not been served. On the other hand the petitioner, Mr. Mehta, states that counsel for the Delhi Administration has appeared and had requested for time to file the counter-affidavit. Though more than six months have elapsed since the order was made, there has been no compliance by the Delhi Administration. In the circumstances, we take it that the Delhi Administration does not want to file any counter-affidavit or take steps in this case and is set ex-parte. 2. The Union of India has also not entered appearance and has not taken any steps in this case inspite of service of notice. Accordingly, Union of India is set ex-parte. No hearing shall be afforded to respondents Nos. 1 and 2 unless they formally apply for recall of today's directions and leave on terms of the costs is granted. 3. A notice shall be issued to the Chief Secretary to the Delhi Administration to show cause as to why there has been failure to comply with the directions given by the Court. Compliance with this notice has nothing to do with the merits of the matter, in respect of which the administration has been debarred from participating in the hearing. The affidavit of the Chief Secretary to be personally given should be before the Court on the 4th May, 1987. The - matter is adjourned to be listed on 4th May, 1987.
