RANGANATHAN, J.


A very short question is involved in this appeal under Section 35-L of the Central Excises & Salt Act, 1944


3. The respondent, M/s Protein Products of India, manufactures ossein and gelatine. It claimed exemption from excise duty under a notification of the Government of India dated June 30, 1979. By this notification one more item was added to a list of items exempted from payment of excise duty under an earlier notification dated March 1, 1975. This item reads as follows


Crushed Bones and bone products


3. The respondent company manufactures the above products from bones. Ossein is prepared from bones by dissolving the mineral part of the bones with phosphoric acid. From the ossein so obtained, gelatine is obtained, by treating the same with alkali. Although gelatine can also be manufactured from other sources such as pig skin and hides, it is common ground that the respondent company was manufacturing gelatine only from bones


4. The Customs, Excise and Gold (Control) Appellate Tribunal (CEGAT) has taken the view that the products manufactured by the respondent company are 'bone products' and that the company is entitled to the benefit of the notification dated June 30, 1979 referred to earlier. The Tribunal pointed out that, admittedly, the raw material for the two products in question is crushed bones. It accepted the argument urged on behalf of the respondent company that the word 'product' only directed attention to the principal raw material from which the product in question is derived. 'Bone products' does not mean that the products must contain visible pieces of bones and that the expression is limited only to the primary products obtained on crushing of bones such as bone sinew, bone grist, and bone meal. Reference was made to the description of gelatine in the Indian Standard Specifications as a "purified product obtained by partial hydrolysis of collagen, derived from skin, white connective tissues and bones of animals" and to a definition of collagen - the white fibers of the connective tissues of the animal body, particularly in the skin (corium), bones (ossein) and tendons". The Tribunal also referred to an earlier order wherein di-calcium phosphate, obtained by treating with acid the mineral portions separated from crushed bones, had been held entitled to the benefit of the same notification, treating it as a 'bone product'


5. The learned Solicitor General, appearing on behalf of the appellant, submitted that the view taken by the Tribunal is erroneous. According to him, the words 'bone products' should be read along with words 'crushed bones' and, therefore, the exemption under the notification is only limited to primary products because they could also be obtained from raw material other than bones, such as pig skin and hides. What is essential, according to him, is to consider whether the products in question retain the principal characteristics and physical properties of crushed bones. On other words, the argument appears to be that only products obtained by a physical processing of bones could be described as bone products but not products obtained by treating bones with chemicals or acids


6. We see no reason to limit the availability of the exemption under notification in the manner contended or on behalf of the appellant. The terms of the notification only refer to two items-crushed bones and bone products and there is no scope for applying any rule of ejusdem generis as contended for by the learned Solicitor General. There is also no justification for importing any limitation as to the nature of the products that are entitled to exemption. We see no logic or principle i holding that only products obtained by a physical treatment of bones such as crushing or powdering would be entitled to exemption and not products obtained by chemical treatment. It is true that as gelatine may be produced not merely from bones but also other things such as the skin and tissues of animals. But, us already mentioned, it is not in dispute that only bones are the raw material from which the products manufactured by the respondent company are derived. It is not the case of the appellant that in the manufacture of gelatine or ossein, other raw materials are also use to such an extent as to completely overshadow or render insignificant the utilisation of bones in the process


7. The products in question are derived merely by the extraction of the mineral parts of the bones. Gelatine is obtained by a further treatment, within alkali, of the ossein manufactured from the bones. It is the collegen which forms the organic content of the bones that is utilised in the manufacture of ossein and gelatine. The word 'products' is defined in Webster's Comprehensive Dictionary as "anything produced or obtained as a result of some operation or work". The expression 'bone products' therefore merely means anything produced or obtained from bones. Whether such derivation is by a simple physical process or by a chemical reaction would seem to make no difference to the end product. Buttermilk, for instance, does not cease to be a milk product merely because a chemical process is involved in the transformation. The ossein and gelatine manufactured by the respondent can, without straining the expression used in the notification, be described as bone products. We are, therefore, in agreement with the view taken by the Tribunal that the products manufactured by the respondent company are entitled to the exemption under the notification dated June 30, 1979


8. We may also here usefully reiterate the observations made by us in Collector of Customs, Bombay v. Swastic Woollen (P) Ltd. with regard to the parameters of interference by this Court in an appeal from the CEGAT. That case concerned the meaning of the expression "wool waste" and, though those observations were made in the context of Section 130-E of the Customs Act, 1962, they are of equal application in the present context as well. We said : (SCC p. 801, para 9)


In the new scheme of things, the Tribunals have been entrusted with the authority and the jurisdiction to decide the questions involving determination of the rate of duty of excise or to the value of goods for purposes of assessment. An appeal has been provided to this Court to oversee that the subordinate Tribunals act within the law. Merely because another view might be possible by a competent court of law is no ground for interference under Section 130-E of the Act though in relation to the rate of duty of customs or to the value of goods for purposes of assessment, the amplitude of appeal is unlimited. But because the jurisdiction is unlimited, there is inherent limitation imposed in such appeals. The Tribunal has not deviated from the path of correct principle and has considered all the rel

evant factor. If the Tribunal has acted bona fide with natural justice by a speaking under, in our opinion, even if superior court feels that another view is possible, that is no ground for substitution of that view in exercise of power under clause (b) of Section 130-E of the Act 9. In the present case the Tribunal has taken into consideration all relevant factor and committed no error of principle or law. Even assuming that the terms of the exemption notification can also lend themselves to a narrower construction which may commend itself to another Tribunal or court that alone can be no ground to interfere with the conclusion reached by the Tribunal 10. We therefore see no reason to entertain this appeal which will stand dismissed.
