JUDGMENT :- This petition raises questions about the licensing under the Industries (Development and Regulation) Act, 1951, of an industry that converts base paper into adhesive stamp paper. 2. The petitioners are a limited company and have a plant in Nasik. The plant was set up in 1969 for the processing of base paper into art and chromo paper and board and laminated paper. 3. On 19th Feb., 1970 a notification' was published by the Union of India, the 1st respondent, in exercise of power conferred by Sec.29-B(1) of the Act. Thereby the 1st respondent exempted from the operation of Secs.10, 11 and 11-A of the Act the industrial undertakings therein mentioned. Clause 2(vi) of the notification provided that no industrial undertaking would be liable (eligible?) for exemption if it related to any of the industries listed in Schedule II annexed thereto. Item 30 of the Sch. II mentioned paper conversion products. The petitioners then applied for an industrial licence under the Act. On 29th July, 1970 the petitioners were issued a carry-on business (C.O.B.) licence by the 1st respondent under the Act. The licence stated that the petitioners would have an installed capacity of 900 tonnes per annum each in respect of art paper, art card and plastic dispersion coated paper and card and other speciality papers. In January, 1971 the petitioners commenced commercial production. On 11th March 1971 they were granted a C.O.B. licence for 3,000 tonnes per annum for the same articles. 4. On 16th Feb., 1973 the 1st respondent issued a notification in exercise of powers under S.29-B(1) of the Act exempting the classes of industrial undertakings therein mentioned from the provisions of Ss.10, 11, 11-A and 13 of the said Act. In respect of undertakings other than small scale units and undertakings manufacturing ancillaries it stated this : "Articles reserved for small scale sector : No such undertakings shall be eligible for exemption for the manufacture of any of the articles specified in Sch. I (articles reserved for the small scale sector)". This notification in terms superseded inter alia the notification of 19th Feb., 1970 mentioned above. In Sch. I, relating to articles reserved for the small scale sector, at item 30 paper conversion products were mentioned. 5. I (articles reserved for the small scale sector)". This notification in terms superseded inter alia the notification of 19th Feb., 1970 mentioned above. In Sch. I, relating to articles reserved for the small scale sector, at item 30 paper conversion products were mentioned. 5. Prior to 1974 the India Security Press, Nasik, which prints stamps for the 1st respondent, was importing much of its requirements of adhesive coated paper for printing stamps. In 1974 or thereabouts it considered the feasibility of setting up its own plant for such paper. This required a large outlay, part of it in foreign exchange. A high power committee was then set up to consider whether adhesive stamp paper of the requisite standard could be indigenously made by existing units. Sometime in 1974 the 1st respondent imposed restrictions on art and chromo paper. Consequently, the petitioners and others making these articles lost their market. The petitioners, with a view to diversify, approached the India Security Press to see if they could make adhesive stamp paper. They set up a pilot plant, which was inspected and approved by the high power committee, and started trial production. In 1975 or thereabouts the petitioners installed additional machinery for the purposes of making adhesive stamp paper. This included a 10 bowl super-calendering machine which was imported upon import licences granted by the 1st respondent. Between 1975 and 1977 the petitioners made adhesive stamp paper on a commercial basis. They received orders pursuant to tenders for about 1500 tonnes from the India Security Press and effected supplies of about 1,000 tonnes. The petitioners filed with the Director General of Technical Development of the 1st respondent returns in respect of such production. 6. In April, 1976 a press note was issued by the 1st respondent with a view to removing ambiguities about the articles that were deemed to be covered under the head of paper conversion products reserved for the small scale sector. The press note clarified that the articles therein enumerated fell under paper conversion products, the future development of which was reserved to the small scale sector. Item 11 thereof mentioned gum tape and item 26 gummed paper, stickers, labels, etc. 7. It appears that a complaint was made by the 3rd respondent, which is a small scale industry, that the petitioners were making adhesive stamp paper which was reserved for the small scale sector. Item 11 thereof mentioned gum tape and item 26 gummed paper, stickers, labels, etc. 7.
