ORDER :— Petitioner 2 and some others are running a restaurant under the name and style of petitioner I on the first floor of premises No. 23/3, East Patel Nagar, New Delhi, since 1970. Petitioners had applied for a licence as required by Sec. 421 of the Delhi Municipal Corporation Act, 1957 (Act for short). In August 1976 petitioners were asked by the Municipal Corporation ("Corporation" for short) to deposit the licence fee from the date of application till March 31, 1977, in the total amount of Rs. 166/- which the petitioner duty deposited on August 17, 1976. A receipt acknowledging the payment of the licence fee was issued. Subsequently every year the licence fee was deposited from. year to year with a request for renewal of licence and every year fresh receipt was issued which would tantamount to renewal of the licence. Such yearly renewal covered the period 1978-79. When the petitioners applied for renewal of the licence for the period April 1, 1979, to March 31, 1980, the Corporation as per its letter dated May 7, 1979, asked the petitioners to comply, with certain requirements as set out therein. The Corporation did not accept the licence fee which was tendered by the petitioners. On May 8, 1991, an employee of the respondent Corporation visited the premises of the petitioners and served a notice purporting to be under Section 423 of the Act intimating to the petitioners that the petitioners licence for eating house has not been renewed since March 31, 1979, because according to the respondent Corporation the restaurant was being run in a residential building. Consequently the petitioners were directed to close the business within 24 hours of the receipt of the notice failing which the trade premises would be scaled. On May 11, 1981, the premises in which the business of the restaurant was being carried on was sealed. A suit was filed by the petitioners for a mandatory injunction directing the respondent to grant licence for the year 1979-80 onwards. A notice of motion under Order XXXIX, Rules 1 and 2 of the Code of Civil Procedure was taken out for an interim injunction for removal of the seals till the disposal of the suit. After the appearance of the respondent the notice of motion was discharged. A revision petition to the High Court met with the same fate and a petition, to obtain special leave against the order of the Delhi High Court was rejected by this Court on May 3, 1982. Thereafter the present writ petition was filed.

2. Number of contentions have been raised in this petition but the only one of which we must take notice and which goes to the root of the matter is that the decision not to renew the licence was arrived at in violation of principles of natural justice and is liable to be quashed on that ground.

3. Section 421 of the Act provides that no person can keep any eating house, lodging house, hotel, boarding house, tea shop, coffee house, cafe, restaurant, except in conformity with the terms of a licence granted by the Commissioner in this behalf. Therefore, for carrying on the business of a restaurant obtaining licence under Section 421 is a prerequisite. It is not in dispute that the petitioners did apply for such licence. In para 11 of the petition the petitioner has stated that the licence was renewed by acceptance of the licence fee for the years 1977-78 and 11979-79. In the affidavit in opposition with regard to the averments in para 11 the only thing stated is that these averments need no reply. Nowhere in the affidavit in opposition it is at all disputed that the licence fee was deposited from year to year and accepted by the Corporation. It may be that the licence in the prescribed form may not have been issued. Therefore, it is an inescapable conclusion that the petitioners were carrying on business of restaurant pursuant to a licence issued or deemed to have been issued by the Corporation.

4. The petitioners further aver that for the year April 1, 1979, to March 31, 1980, even though the peti
