Summarize the following court judgment. Appeal No. 1369 of 1968. Appeal from the judgment and order dated August 1	 1967 of the Andhra Pradesh High Court in Case Referred No. 68 of 1964. section T. Desai	 J. Ramanurthi	 R. N. Sachthey and B. D. Sharma	 for the appellant. M. Natesan and K. Jayaram	 for the respondent. The Judgment of the Court was delivered by Grover	 J. This is an appeal by certificate from the judgment of the Andhra Pradesh High Court in a case referred under section 66(1) of the Income Tax Act	 1922 (hereinafter referred to as the Act). The respondent who is the assessee is a registered firm running a hotel at Secunderabad with branches at Sultan Bazar and King Kothi in Hyderabad. During the previous year ending 30th September	 1959 relating to the assessment year 1960 61	 the assessee incurred an expenditure of Rs. 57	154/ in installing sanitary fittings and of Rs. 1	370/ for pipe line fittings. The assessee claimed development rebate on these two items at the rate of 25 per cent under section 10(2)(vi b) of the Act amounting in the aggregate to Rs. 14	629/ . The Income Tax Officer disallowed the claim. On appeal	 the Appellate Assistant Commissioner upheld the disallowance. An appeal was taken to the Appellate Tribunal. The Tribunal rejected the appeal holding that the definition of "plant" must necessarily be the same	 whether it was for claiming depreciation under section 10(2)(vi) or for development rebate under section 10(2)(vi b). Accordingly	 it was held that the sanitary and pipe line fittings did not fall within the meaning of the word "plant". On being moved under section 66(1) of 170 the Act	 the following question was referred for the opinion of the High Court : "Whether the sanitary fittings and pipelines	 installed in the King Kothi branch of the Hotel	 constituted 'plant ' within the meaning of sec. 10(5) of the Indian Income tax Act and whether the assessee is entitled to develop ment rebate in respect thereof under sec. 10(2) of the Act The High Court answered the question in the affirmative and in favour of the assessee. The only question that was argued before the High Court and which has been debated before us is whether sanitary and pipe line fittings in a building which is run as a hotel would fall within the meaning of the word "plant" in section 10(2)(vi b) of the Act. Section 10(1) of the Act provides that tax shall be payable by an assessee in respect of the profits and gains of any business profession or vocation. Sub section (2) gives the allowances which have to be made in computation of such profits and gains. Clause (vi) of that sub section relates to the depreciation in respect of "such buildings	 machinery	 plant or furniture being the property of the asses see". Clause (vi b) of section 10(2) is as follows: "(vi b) in respect of a new ship acquired or new machinery or plant installed after the 31st day of March	 1954	 which is wholly used for the purposes of that business carried on by the assessee	 a sum by way of development rebate in respect of the year of acquisition of the ship or of the installation of the machinery or plant	 equivalent to. . . Section 10(5) provides inter alia that in sub section (2) " plant" includes "vehicles	 books	 scientific apparatus and surgical equipment purchased for the purpose of the business	 profession or vocation". 171 The main argument of the learned counsel for the Commissioner of Income Tax who is the appellant is that the word "plant" should not have been given a wide meaning and should have been interpreted according to the common understanding in commercial circles among persons who deal in plant and machinery. It is asserted that the development rebate cannot be claimed in respect of the items which have become a part of the building itself. It has also been pointed out that the assessee while claiming depreciation allowance has included the assets in question under the head "furniture and fittings" the rate claimed being 9 per cent which was duly allowed by the Income Tax Officer. This rate of 9 per cent was applicable under Rule 8 only to furniture and fittings used in hotels etc. If the assets were to be treated as plant	 only the general rate of 7 per cent would be applicable. The definition of "plant" must necessarily	 therefore	 be the same whether it be for claiming depreciation under section 10(2)(vi) or for development rebate under section 10(2)(vi b). It has also been suggested that the primary meaning of the word "plant" has connection with mechanical or industrial business or manufacture of finis hed goods from raw goods and that sanitary and pipe line fittings could not possibly satisfy those conditions. Now it is well settled that where the definition of a word has not been given	 it must be construed in its popular sense if it is a word of every day use. Popular sense means "that sense which people conversant	 with the subject matter with which the statute is dealing	 would attribute to it". In the present case	 section 10(5) enlarges the definition of the word "plant" by including in it the words which have already been mentioned before. The very fact that even books have been included shows that the meaning intended to be given to "plant" is wide. The word "includes" is often used in interpretation clauses in order to enlarge the meaning of the words or phrases occurring in the body of the statute." When it is so used	 these words and phrases must be construed as comprehending not only such things as they signify according to their nature and import but also those things which the interpretation clause declares that they shall include. The word "include" is also susceptible of other constructions which it is unnecessary to go into. 172 The case J. Lyons and Company Limited vs Attorney General (1) relied upon by the learned counsel for the appellant apart from being distinguishable hardly supports the contention of the appellant. In that case	 it was I held that electric lamps and fittings in a tea shop were not part of the apparatus used for carrying on the business but were part of the setting in which the business was carried on	 and	 therefore	 were not "plant"	 within the meaning of certain provisions of the War Damage Act	 1943. It was observed at page 286 "if these articles are plant	 it can only be by reason that they are found on premises exclusively devoted to trade purposes. Trade plant alone need be considered". ' The meaning of "plant" as given in Yar mouth vs France (2) was accepted as correct. According to that meaning "plant" includes whatever apparatus or instruments are used by a businessman in carrying on his business". In our judgment	 the more apposite decision is that of the Court of Appeal in Jarrold (Inspector of Taxes) vs John Good & Sons Ltd. (3) There the nature of the assessee 's business required that its office accommodation should be capable ' of sub division into a number of rooms varying in size etc. according to the requirements from time to time of the agencies which it carried on. The office accommodation consisted of a large open floor space in which partitions could be erected so as to subdivide the floor space into a number of rooms of any size. Certain partitions were made which were screwed to the floor and ceiling only and could be easily moved if it was desired to alter the size of number of the rooms. The question was whether these partitions were plant within sections 279 and 280 of the English Income Tax Act 1952	 so as to entitle the company to allowances under those sections. There the material words in the statute were "where the person carrying on a trade in any year of assessment has incurred expenditure on the provision of machinery or plant for the purposes of the trade. " It was held that the partitions were "plant" as they were used in the carrying out of the company 's trade or business. Donovan	 L.J. held that the partitions were used to enable the trader to cope with the vicissitudes of (1) 1. (2) (3) 173 the business as it increased and diminished and relied on the finding of the commissioners that the flexibility of accommodation which the partitions provided was a commercial necessity for the company. Further illustrations were given of assets which would fall within the meaning of "plant". "The heating installation of a building may be passive in the sense that it involves no moving machinery	 but few would deny it the name of plant". The same thing could	 no doubt be said of many air conditioning and water softening installations". It cannot be denied that the business of hotelier is carried on by adapting a building or premises in a suitable way to be used as a residential hotel where visitors come and stay and where there is arrangement for meals and other amenities are provided for their comfort and convenience. To have sanitary fittings etc. in a bath room is one of the essential amenities or conveniences which are normally provided in any good hotel	 in the present times. If the partitions in Jarrold 's case (supra) could be treated as having been used for the purpose of the business of the trader	 it is incomprehensible how sanitary fittings can be said to have no connection with the business of the hotlier. He can reasonably expect to get more custom	 and earn larger profit by charging higher rates for the use of rooms if the bath rooms have sanitary fittings and similar amenities. We are unable to see how the sanitary fittings in the bath rooms in a hotel will not be "plant" within s.10(2)(vi b) read with Section 10(5) when it is quite clear that the intention of the Legislature was to give it a wide meaning and that is why	 articles like books and surgical instruments were expressly included in the definition of "plant". In decided cases	 the High Courts have rightly understood the meaning of the term "Plant" in a wide sense. (See Commissioner of ' Income tax	 U.P. vs Indian Turpentine and Rosin Co. Ltd.). (1) If the dictionary meaning of the word "plant" were to be taken into consideration on the principle that the literal construction of a statue must be adhered to unless the context renders it plain that such a construction cannot be put on the words in question this is what is stated in Webster 's Third New International Dictionary: (1) 17 4 "Land	 buildings	 machinery	 apparatus and fixtures employed in carrying on trade or other industrial business. It is	 however	 unnecessary to dwell more on the dictionary meaning because looking to the provisions of Act	 we are satisfied that the assets in question were required by the nature of the hotel business which the assessee was carrying on. They were not merely a part of the setting in which hotel business was being carried on. The High Court was right in not accepting the reasoning of the Tribunal based on the rates relating to depreciation under s.10(2)(vi) and the assessee having claimed that the sanitary and pipe line fittings fell within the meaning of "furniture and fittings ' in Rule 8(2) of the Rules. It has been rightly observed that the Rules were meant only for the purpose of carrying out the provisions of the Act and they could not take away what was conferred by the Act or whittle down its effect. If the assessee had claimed higher depreciation allowance that would not detract from the meaning of the word plant in clause (vi b) of section 10(2). In the result	 this appeal fails and it is dismissed with costs. V.P.S. Appeal Dismissed.

During the assessment year 1960 61	 the assessee	 a registered firm running hotels	 incurred expenditure in installing sanitary and pipeline fittings in its hotels. On the question whether such fittings in a building run as a hotel fell within the meaning of the word 'plant ' in section 10(2)(vi b) of the Income tax Act	 1922	 and the assessee was therefore entitled to development rebate under that sub section	 the High Court	 in reference	 answered in favour of the assessee. Dismissing the appeal to this Court	 HELD: (1) Apart from the dictionary or literal meaning of the word 'plant '	 the context of the provisions of the Act shows that sanitary and pipe line fittings are 'plant ' under section 10(2)(vi b) read with section 10(5). [173H; 174A B] In computing the profits and gains of a business under section 10(1) o the Act allowances by way of depreciation in respect of 'plant ' under section 10(2)(vi) and by way of development rebate in respect of 'plant ' under section 10(2)(vi b) have to be made. Under section 10(5)	 'plant ' includes vehicles	 books	 scientific apparatus and surgical equipment purchased for the purpose of the	 business profession or vocation. Where a word is not defined in a statute	 it must be construed in its popular sense	 that is	 that sense which people conversant with the subject matter with which the statute is dealing	 would attribute to it. The word 'includes ' is generally used to enlarge the meaning of words or phrases used in the statute so that	 words and phrases may be construed as comprehending not only such things as they signify according to their nature and import	 but also these things which the interpretation clause declares that they shall include. The fact that even books have been included in 'plant ' shows that the meaning given to 'plant ' is wide. It should cover sanitary and pipe line fittings. [170E H; 171E H	 173F] To have such fittings in a bath room is one of the essential amenities or conveniences which are normally provided in any good hotel	 and the hotelier can reasonably expect to get more custom and earn a larger profit by charging higher rates. Therefore	 the fittings in the present case	 were not merely a part of the setting in which the hotel business was being carried on	 but were required for the purpose of the hotel business. [173C G] C.I.T.	 U.P. vs Indian Turpentine and Rosin Co. Ltd.	 (1 970) 	 approved. Jarrold (Inspector of Taxes) vs John Good & Sons Ltd.	 	 applied. 169 J. Lyons Co. Ltd. vs Attorney General	 and Yar mouth vs France	 	 referred to. (2) The fact that the assessee while claiming depreciation allowance had included the fittings in question under the head 'furniture and fittings ' and claimed higher depreciation allowance than what would be applicable to 'plant '	 would not detract from the meaning of the word 'plant ' in section 10(2)(vi b).
