Summarize the following court judgment. Civil Appeal No. 50 of 1988. From the Judgment and order dated 14.8.87 of the Punjab & Haryana High Court in Civil Revision No. 2836 of 1982. Dr. Meera Aggarwal for the Petitioner. 347 A.B. Rohtagi	 Mukul Rohtagi	 Atul Tewari and Ms. Bina Gupta for the Respondent. The Judgment of the Court was delivered by SABYASACHI MUKHARJI	 J. This appeal by special leave is directed against the judgment of the High Court of Punjab and Haryana dated 14th August	 1987. The appellant took on rent the premises in dispute from the respondent at a monthly rent of Rs. 120 and executed a rent note in his favour on 19th April	 1975. Clause 4 of the said rent note provided	 inter alia	 as follows: "That the tenant will run the business of English Liquor Vend in the shop will do sale of Liquor. " The landlord	 respondent herein filed a petition under section 13 of the Haryana Urban (Control of Rent & Eviction) Act	 1973 (hereinafter called 'the Act ') against the appellant on the ground of arrears of rent from 1.4.1979 to 31.8.1979 and change of user from Liquor Vend business to that of general merchandise at the shop in dispute by the appellant. The appellant tendered the entire arrears of rent at the first date of hearing and thereafter he contested by filing written statement. The appellant submitted that after March	 1979	 the licence of liquor vend in his favour was not renewed and he had to discontinue that business of liquor vend at the shop in dispute and had to start the business of general merchandise. According to the appellant the purpose of the user still remains commercial and that in the rent note there was no clause prohibiting the appellant to change any other business in the shop in dispute. The Rent Controller held that the appellant had changed the user of the shop in dispute and he was liable for eviction under the Act. There was an appeal to the Appellate Authority and the Appellate Authority dismissed the said appeal. The appellant went in civil revision to the High Court of Punjab and Haryana. The High Court dismissed the civil revision and upheld the eviction. Hence this appeal. The question is	 whether a ground for eviction was made out under clause (b) of section 13(2)(ii) of the Act. The said Act was passed to control the increase of rent of certain buildings and rented land situated within the limits of urban areas	 and the eviction of the 348 tenants therefrom. Section 13(2)(ii)(b) of the Act reads as follows: "13(2) A landlord who seeks to evict his tenant shall apply to the Controller	 for direction in that behalf. If the Controller	 after giving the tenant a reasonable opportunity of showing cause against the application is satisfied: (i) XX XX XX (ii) that the tenant has after commencement of 1949 Act	 without the written consent of the landlord (a) XX XX XX (b) used the building or rented land for a purpose other than that for which it was leased. " The High Court of Punjab and Haryana has relied on a Full Bench decision of the said High Court in Sikander Lal vs Amrit Lal	 [1984] Punjab Law Reporter 1. That was a case under the East Punjab Urban Rent Restriction Act of 1949. The Full Bench of the Punjab and Haryana High Court in the facts and circumstances of that case held that it was a common ground that the premises was originally leased for the business of handlooms. Thereafter it was used for small carding machine not occupying a space of more than 4 feet x 4 feet which converted cloth into thread. It was held that there was no change of user. The Full Bench	 however	 observed that it emerged from the long line of authorities that where the subsequent use of the premises is merely ancillary to the specific original purpose then it would imply no change of user within the meaning of the statute. If by custom or convention or on the finding of the Court it could be held that the added use of the premises was ancillary to the main original purpose then in the eye of law it would be deemed to have been within the terms of the original lease. It was further held that both on principle and on binding precedent it emerged that the specified original purpose could not be	 according to the Full Bench	 extended by adding to it any and every purpose thereto	 and the same must be confined within the limitation of being either a part or parcel of	 or ancillary to	 the original purpose. There the Court was concerned with section 13(2)(ii)(b) of the Act which is an identical provision as the present one. So far as the High Court held in that case that allied business would not amount to change of user but for a business which is not allied for the business for which it was let out would amount to change 349 of user come within the mischief of clause (b) of section 13(2)(ii) of the Act	 the same must be read with reservation. Our attention was drawn to a decision of this Court in Maharaj Kishan Kesar vs Milkha Singh and others	 (Civil Appeal No. 1086 of 1964 decided on 10th of November	 1965. That was a decision under the East Punjab Urban Rent Restriction Act	 1949. There on the facts the Court found that selling petrol was an allied business of the workshop and as such it is a part of the business. The Court held that there is no evidence to show that in the trade a petrol pump is not regarded as a part of motor workshop business. The sale of petrol is an allied business and would not amount to conversion to a different business or change of user. There is nothing in the said decision which would give any assistance to the respondent in this case. The business purposes must be adjudged in the light of the purposes of the Rent Act in question which is to control the eviction of tenants therefrom. In the expanding concept of business now a days and the growing concept of departmental stores	 we are of the opinion that it cannot be said that there was any change of user in the facts of this case which would attract the mischief of the provisions of section 13(2)(ii)(b) of the Act. The building was rented for purpose of carrying on a business	 using it for another business	 it will not in any way impair the utility or damage the building and this business can be conveniently carried on in the said premises. There was no nuisance created. Our attention was drawn to the observations of Lord Diplock in Duport Steels Ltd. and others vs Sirs and others	 at 541. That was a decision in respect of the Trade Disputes Act 1906. Lord Diplock said: "My Lords	 at a time when more and more cases involving the application of legislation which gives effect to policies that are the subject of bitter public and parliamentary controversy	 it cannot be too strongly emphasised that the British Constitution	 though largely unwritten	 is firmly based on the separation of powers: Parliament makes the laws	 the judiciary interpret them. When Parliament legislates to remedy what the majority of its members at the time perceive to be a defect or a lacuna in the existing law (whether it be the written law enacted by existing statutes or the unwritten common law as it has been expounded by the judges in decided cases)	 the role of the judiciary is confined to ascertaining from the words that Parliament 350 has approved as expressing its intention what that intention was	 and to giving effect to it. Where the meaning of the statutory words is plain and unambiguous it is not for the judges to invent fancied ambiguities as an excuse for failing to give effect to its plain meaning because they themselves consider that the consequences of doing so would be inexpedient	 or even unjust or immoral. In controversial matters such as are involved in industrial relations there is room for differences of opinion as to what is expedient	 what is just and what is morally justifiable. Under our constitution it is Parliament 's opinion on these matters that is paramount. While respectfully agreeing with the said observations of Lord Diplock	 that the Parliament legislates to remedy and the judiciary interpret them	 it has to be borne in mind that the meaning of the expression must be found in the felt necessities of time. In the background of the purpose of rent legislation and in as much as in the instant case the change of the user would not cause any mischief or detriment or impairment of the shop in question and in one sense could be called an allied business in the expanding concept of departmental stores	 in our opinion	 in this case there was no change of user which attract the mischief of section 13(2)(ii)(b) of the Act. The High Court	 therefore	 was in error. In that view of the matter this appeal is allowed and the order of eviction is set aside. The parties will pay and bear their own costs. N.V.K. Appeal allowed.

% The appellant tenant took on rent the suit premises from the respondent landlord on a monthly rent of Rs.120 and executed a rent note in his favour on 19th April	 1975. Clause 4 of the rent note provided that the tenant was to run the 'business of English Liquor Vend	 and do sale of liquor in the shop. ' The respondent filed a petition for eviction under section 13 of the Haryana Urban (Control of Rent & Eviction) Act	 1973 against the appellant on the ground of ground of rent from 1st April	 1979 to 31st August	 1979 and change of user from liquor vend business to that of general merchandise. The appellant tendered the entire arrears of rent at the first date of hearing	 and contested the eviction petition by filing a written statement contending that after March	 1979 the licence of liquor vend in his favour was not renewed	 and he had to discontinue that business at the suit premises	 and had to start the business of general merchandise. It was	 further	 contended that the purpose of user still remained commercial and that there was no clause in the rent note prohibiting the appellant to change to any other business. The Rent Controller held that the appellant had changed the user of the shop in dispute and that he was liable for eviction under the Act. 346 The Appellate Authority dismissed the appeal. The High Court also dismissed the Civil Revision and upheld the order of eviction. Allowing the Appeal	 this Court	 ^ HELD: 1. The business purposes must be adjudged in the light of the purposes of the Rent Act in question which is to control the eviction of tenants therefrom. [349C] 2. In the expanding concept of business nowadays and the growing concept of departmental stores	 it cannot be said that there was any change of user in the instant case	 when the tenant converted the use of the building from liquor vend business to that of general merchandise. The building was rented for the purpose of carrying on a business. It was used for another business which would not in any way impair the utility or damage to the building	 and the business could be conveniently carried on in the said premises. No nuisance was also created. The case would	 therefore	 not attract the mischief of section 13(2)(ii)(b). [349D	 350E] 3. So far as the High Court of Punjab and Haryana held in the Full Bench decision in Sikander Lal vs Amrit Lal	 (1984 Punjab Law Reporter 1) that allied business would not amount to change of user but for a business which is not allied for the business for which it was let out would amount to change of user come within the mischief of clause (b) of section 13(2)(ii) of the Act	 the same must be read with reservation.

When Parliament legislates to remedy a defect or a lacuna in the existing law	 and the judiciary interprets them	 it has to be borne in mind that the meaning of an expression must be found in the felt necessities of time.
