only provides for supply of food or any other article for human consumption to bring it within the extended definition of "sale". The petitioners contended that the definition introduced under the explanation (3C) to the term "sale" contained in S. 2(xxi) of the Act contemplates only food and articles of human consumption and the same does not take in "medicine". Even though the amendment was brought to cover hotels, the legislative intent is to enlarge the scope of the operation of the Act to cover sales effected in the course of rendering services also. Moreover, in the definition clause of "dealer" the supply of goods in the course of rendering service is not limited to food and articles of human consumption alone. Further, it is also not possible to compare the case of supply of food as part of service in a hotel and supply of medicine in the course of medical treatment. There is substantial difference between these two transactions. While food served to a guest in a hotel is only incidental and part of service, the supply of medicine in the course of treatment is not just incidental, but it is the main and integral part of treatment and supply by itself or sale of medicine as such is part of business in the hospital. It is not disputed that the hospitals are independently billing and charging for the medicines supplied and as already stated, going by the value of medicines involved in treatment, it is the main component of the cost to the patient and it is not an incidental transaction at all. In other words, sale of medicine is in terms of volume, frequency, continuity, regularity and in all other aspects it is one of the main activities in the hospital. Therefore, such of the hospitals which are supplying medicines of the value in excess of the turnover for which registration is required i.e. Rs. 2 lakhs in an year are liable to be registered under the K.G.S.T. Act. The decisions referred to by the petitioners do not apply or are at least not relevant here. The decision in State of Tamil Nadu v. Board of Trustees of the Port of Madras (114 STC 520) was rendered by the Supreme Court in the context of statutory service rendered by the Port Trust and other services and the transaction involved there was only sale of scrap materials which is occasional and incidental. Whereas in the case of hospitals, as found earlier the sale of medicine
