Judgement GADGIL J. - The only question that arises for our determination in this writ petition is as to whether the provisions of S.237 of the City of Nagpur Corporation Act, and the bye-laws framed thereunder providing the necessity of having a licence for carrying on certain business such as hotel etc. stand repealed on account of the licensing provisions of such establishment under the Prevention of Food Adulteration Act and the Rule made thereunder. 2. Petitioner No. 1 is an association of hotel owners at Nagpur, while petitioners 2 to 5 are its members, Respondent No. 1 is the Corporation of City of Nagpur, while the State of Maharashtra is the second respondent. It is not in dispute that the petitioners 2 to 5 are carrying on their hotel business at Nagpur. On 27-7-1959; certain bye-laws framed by the City of Nagpur Corporation (hereinafter referred to as the Corporation) under S.415(35) read with S.237 of the City of Nagpur Corporation Act (hereinafter referred to as the Corporation Act) came into force. S.237 of the Corporation Act provides that the Corporation may, by bye-laws prohibit the manufacture, sale or preparation or exposure for sale, of any specified article of food or drink, in any place or premises not licensed by the Corporation. The bye-laws so framed are at Annexure-A to the petition. We well later on refer in details to these bye-laws but at this juncture it would be sufficient to state that the bye-laws as also the terms of the licence have made provision that the premises in which the articles of food are prepared or sold, should be in a good, sanitary and hygienic condition. They should be away from the urinals and drainage and there must be necessary arrangements for proper cleanliness and lighting. The bye-laws also provides that no person should be allowed to work on the premises who is suffering from tuberculosis and who have not been vaccinated against small pox. Petitioners 2 to 5 have obtained the necessary licence on payment of the licence fees. 3. The Prevention of Food Adulteration Act (hereinafter referred to as the Food Act) came into force in 1955. S.23 of this Act empowers the Central Government to make certain rules for the purpose of carrying out the provisions of the Act. Petitioners 2 to 5 have obtained the necessary licence on payment of the licence fees. 3. The Prevention of Food Adulteration Act (hereinafter referred to as the Food Act) came into force in 1955. S.23 of this Act empowers the Central Government to make certain rules for the purpose of carrying out the provisions of the Act. Sub-Sec. (1-A) states that in particular, these Rules may provide for a number of matters, including the maintenance of the premises in a sanitary condition and maintenance of the healthy state of human beings associated with the production, distribution and sale of such article or class of articles. The Central Government has framed such Rules in 1955 and they are known as the Prevention of Food Adulteration Rules in 1955 (hereinafter referred to as the Rules), R.50 enumerates the conditions for licence that are to be issued under the Food Act and sub-rule (5) provides that the premises where the food is to be sold must be free from any sanitary defects. Section 24 of the Food Act empowers the State Government to frame rules. In particular, those rules can prescribe the forms of licences for the manufacture, sale and storage of articles of food. The State of Maharashtra has accordingly framed such rules in the year 1962. Annexure-B to this petition is a form of licence prescribed by these rules. It enumerates the conditions on which the licence is issued. Some of the conditions pertain to the sanitation and hygiene; e.g. there is a condition that the floor and the drain should be thoroughly cleaned every day and that only the water from municipal or other approved source should be used. The surface of the walls is required to be rendered smooth. There is a prevention of mixing cow milk, with buffalo milk or goat milk. The licensee is not permitted to keep on a public road any vessels intended to be used for keeping the licensed articles. Petitioner Nos. 2 to 5 have obtained licences under the Food Act an 1962 (i.e. the year in which the Maharashtra Rules came into force). It seems that thereafter the Corporation did not insist on a separate licence under the Corporation Act. However on 11-3-1971, the Corporation issued a press-mote directing that the licences required by the abovementioned bye-laws of the Corporation should be got renewed. The similar press-note was issued on 4-6-1971. It seems that thereafter the Corporation did not insist on a separate licence under the Corporation Act. However on 11-3-1971, the Corporation issued a press-mote directing that the licences required by the abovementioned bye-laws of the Corporation should be got renewed. The similar press-note was issued on 4-6-1971. The two press-notes are annexures C and D to this petition. The petition
