Summarize the following court judgment. Appeal No. 1744 of 1976. (Appeal by Special Leave from the Judgment and Order dated 28.4.1975 of the Punjab & Haryana High Court in Civil Writ Petition No. 1819/75) M.K. Ramamurthi and J. Ramamurthi	 for the appellants. Madan Mohan	 for the respondents 4 8	 10 25	 27 30 & 32 36. B.D. Sharma & R.N. Sachthey	 for respondents 1 2. The Judgment of the Court was delivered by JASWANT SINGH	 J. This appeal by special leave which is directed against the judgment and order dated April 28	 1975	 of the High Court of Punjab and Haryana at Chandigarh	 dismissing Civil Writ Petition No. 1819 of 1975 filed by the appellants and respondents 3 to 37 herein	 who are industrial workers employed in Factories situate in the industrial area in Chandigarh. The facts leading to this appeal are: In 1956	 the Legislature of the then State of Punjab enacted what is called the Punjab Industrial Housing Act	 1956 (Punjab Act 16 of 1956) (hereinafter referred to as 'the Act ') to pro vide for allotment	 recovery of rent	 eviction and other ancillary matters in respect of houses constructed under the subsidised Industrial Housing Scheme for industrial workers in the State of Punjab. In exercise of the powers conferred on it under section 24 of the Act	 the State Government made rules called the Punjab Industrial Housing Rules	 1956 (hereinafter referred to as the Rules '). Rule 4 of the Rules as originally made ran as under: "4. Eligibility for allotment (1) Two roomed tenements shall be allotted to indus trial workers whose income exceeds Rs. 100 per mensem. (2) One roomed tenements shall be allotted to workers with an income not exceeding Rs	100 per mensem. " 329 This rule was amended vide Notification No. 4119 2HG 6C 29333 dated October 5	 1960. The rule	 after its aforesaid amendment	 read as under: "4. Eligibility for allotment (1) Two roomed tenements shah be allotted to industrial workers whose income does not exceed Rs. 350.00 per mensem. (2) One roomed/small two roomed tenements shall be allotted to workers with an income not exceeding Rs. 250.00 per mensem; provided that where sufficient number of industrial workers with income exceeding Rs. 250.00 per mensem is not forthcoming for allotment	 the Labour Commissioner may	 with the approval of the State Government	 allot two roomed tene ments to industrial workers with an incOme not exceeding Rs. 250.00 per mensem. Notes: In towns	 where only roomed/small two roomed tenements have been built	 applica tions should first be invited from such work ers only	 whose monthly income does not exceed Rs. 250.00. It is only after the demand from these workers has been met that unallotted tenements should be made available for allot ment to workers	 whose income exceed Rs. 250.00 per mensem. Where these tenements are given to higher paid workers the normal subsi dised rent should be charged from them till such time as the regular two roomed tenements do not become available for them. When the two roomed tenements become available the higher paid workers must be removed from the smaller tenements	 failing which they should be charged the full economic rent. (ii) In cases where after allotment of one roomed/small two roomed tenements a worker crosses the wage limit of Rs. 250.00 per mensem	 he may be allowed to continue in occupation of the house allotted to him on payment of subsidised rent	 till such time as the regular two roomed house does not become available	 in other respects the procedure as prescribed in note (i) should be followed. (iii) Two roomed tenements should in the first instance	 be offered from allotment to workers whose income is between Rs. 251.00 and Rs. 350.00 per mensem." Vide Notification No. 7480 4H(8) 72/21542 dated Novem ber 7	 1972	 the Chief Commissioner	 Union Territory	 Chand igarh	 made in exercise of the powers conferred by section 24 of the Act what are called the Punjab Industrial Housing	 Chandigarh (First Amendment) Rules	 1972 adding the fol lowing	 	after sub rule (2) in Rule 4 of the Rules: 330 "(3) An industrial worker shall become ineligible to retain the industrial house allotted to him from the date his income exceeds Rs. 350/ per mensem and his allotment of it shall stand cancelled with effect from that date. Provided that in case such an industrial worker has been allotted and is in occupation	 of an industrial house immediately before the commencement of the Punjab Industrial Hous ing (Chandigarh First Amendment) Rules	 1972	 his allotment shall be cancelled by the Labour Commissioner after giving him one month 'S notice in writing of such cancella tion. Chief Commissioner also ordained that the following shall be added in form 'C ' of the Rules after condition (24) : "(25) The allottee shall become ineligible to retain the industrial house	 allotted to him from the date his income exceeds rupees 350 per mensem and his allotment shall be deemed to have been cancelled from that date. " The appellants and the aforesaid respondents	 who were allottees of houses in Sector 30	 Chandigarh constructed by the State Government for occupation of industrial workers under the Industrial Housing Scheme subsidised by the Central Government and declared under section 3 (2) of the Act to be houses covered by the provisions of the Act were given notices. by the Labour Inspector	 Union Territory	 Chandigarh	 in terms of the proviso to sub rule (3) of rule 4 of the Rules	 as amended by the aforesaid Notification No. 74804H(8) 72/21542 dated November 7	 1972	 calling upon them to show cause as to why the allotment of houses made to them should not be cancelled as the income of each one of them exceeded Rs. 350/ per mensem which disentitled them to retain their respective allotments. The appellants and the aforesaid respondents thereupon filed a joint writ petition	 being writ petition No. 1819 of 1975 under Arti cles 226 and 227 of the Constitution in .the High Court of Punjab and Haryana for issue of an appropriate writ	 order or direction quashing the said notices and notification No. 7480 4H(8) 72/21542 dated November 7	 1972 amending Rule 4 of the Rules and restraining respondents 1 and 2 from pro ceeding with the cancellation of their respective allotments and evicting them from the houses. They contended that the aforesaid rule 4 as amended was ultra vires the Act in so far as it carved out an exception to the statutory defini tion of "industrial worker ' as contained in section 2(e) of the Act within the scope of which they admittedly fell. The High Court repelled their contention and dismissed their writ petition by its judgment dated April 28	 1975. Ag grieved by this judgment and order	 the appellants and the said respondents made an application to the High Court for issue of a certificate of fitness under Article 133 of the Constitution which was refused by the High Court by its order dated May 9	 1975. Thereupon they moved this Court for special leave under Article 136 of the Constitution which was granted. 331 Appearing in support of the appeal	 Mr. Ramamurthy has reiterated before us that since the appellants and respond ents 3 to 37 are admittedly industrial workers as defined in clause (e) of section 2 of the Act	 the impugned rule 4 which is designed to cancel their allotment	 on the ground that their salary exceeded Rs. 350/ per mensem is clearly repugnant to that clause and as such utra vires and invalid as it takes out industrial workers with income exceeding Rs. 350/per mensem from the scope of the definition. He has further contended that since the authority competent to make rules under section 24 of the Act cannot frame any rule having a retrospective effect and the impugned rule rule 4(3) as amended operates retrospectively	 the same is in valid. He has lastly urged that the impugned notification is also invalid as if makes hostile and arbitrary discrimi nation against industrial workers whose income exceeds Rs. 350/ per mensem	 and thereby violates the guarantee en shrined in Article 14 of the Constitution. We shall deal seriatim with all the three contentions raised by Mr. Ramamurthy. Before embarking on that task	 we consider it appropriate to scan the scheme of the Act. Section 3 of the Act clearly states that the Act shall be applicable to houses constructed by the State Government for the occupation of industrial workers under the Industrial Housing Scheme subsidised by the Central Government. The scheme	 as evident from the affidavit of the Home Secre tary	 Chandigarh Government	 is meant for the benefit of the low aid industrial workers and economically weaker sections of the community. Section 9(1) of the Act provides that the occupation by any person of a house shall at all times be subject to such conditions relating to its occupation as may be prescribed	 or as may be intimated from time to time by the Labour Commissioner. Section 7 of the Act sets out the circumstances in which a person shall be treated to be in unauthorised occupation of any house. Clause (b) of the section explicity states that a person shall be deemed to be in unauthorised occupation "Where being an allottee he has by reason of cancellation of an allotment under sub sec tion (2) of section 9 ceased to be entitled to occupy the house". Sub section (2) of section 9	 which is necessary to be referred to at this stage and which because of the non obstante clause contained in its opening part overrides all other laws for the time being in force	 authorises the Labour Commissioner after giving notice to the allottee and considering the explanation tendered by him to cancel the allotment under which a house is held or occupied by him. Section 24 of the Act not only empowers the State Government generally to make rules to effectuate the purposes of the Act but also specifically confers on it the power to make rules to provide inter alia for the manner of allotment of accommodation and conditions relating to its occupation [see section 24(2)(ii)] as also for the matters which are to be or may be prescribed [see section 24(2)(x)]. A conspectus of the aforesaid provisions of the Act leaves no room for doubt that the allotment of accommodation to an industrial worker is not unconditional but is subject to conditions which can be changed unilaterally by the Government from time to time by altering the rules in exercise of the powers conferred on it 331(a) under section 24 of the Act. Section 7 of the Act which embodies a deeming provision gives a mandate to treat a person as an unauthorised occupant not only if he ceases to be an industrial worker under the Act but also if being an allottee	 he ceases to.be entitled to occupy the accommoda tion by reason of cancellation of the allotment under sub section (2) of section 9 of the Act. A combined reading of sections 7 and 9 of the Act goes to show that if at any time a person becomes an unauthorised occupant of the house by reason of his ceasing to be an industrial worker or by otherwise ceasing to fulfil any of the prescribed conditions then in force including the one relating to the limit of his income	 he becomes amenable to action under section 9(2) of the Act. The result is that even though the allottee may continue to be an industrial worker	 still the allotment under which he holds a house can be cancelled if his occupa tion becomes un authorised on any one of the grounds laid down in section 7 of the Act. We are	 therefore	 satis fied that the impugned amendment which squarely falls within the purview of the aforesaid provisions of section 24 of the Act was validly made and the contention urged by Mr. Rama murthy that it is ultra vires is misconceived and untenable. We may state here in passing that the aforesaid scheme being meant for the benefit of the low paid industrial workers and the number of the houses constructed thereunder being very limited	 the Government could legitimately evolve the method which it did to disentitle industrial workers like the appellants whose monthly salaries appear to range between Rs. 974.71 and Rs. 1861.27 and the aforesaid respondents whose monthly income is also relatively large to retain the houses in question. The contention of Mr. Ramamurthi that the impugned rule is retroactive in operation is also devoid of merit. A careful study of the proviso to rule 4(3) of the Rules which appears to have been inserted to allay fears and remove misapprehensions would show that the rule is not intended to operate retrospectively on industrial workers who had been allotted and were in occupation of industrial houses immedi ately before the amendment of the Punjab Industrial Housing (Chandigarh First Amendment) Rules	 1972. It une quivocally states that allotment of an industrial worker who is in occupation of an industrial house in pursuance thereof immediately before the amendment of the Punjab Industrial Housing (Chandigarh First Amendment) Rules	 1972 shall not be cancelled without one month 's notice in writing. The proviso therefore clearly shows that the allotment of an in dustrial worker whose income exceeds Rs. 350/ per mensem is to stand cancelled not from the date when his income started exceeding Rs. 350/ per mensem but on the expiry of one month 's notice in writing of the cancellation. The second contention raised by Mr. Ramamurthi is also	 therefore	 repelled. The third contention advanced by the learned counsel on behalf of the appellants not having been raised before the High Court cannot be permitted to be raised at this stage. The contention can also not be allowed to be raised in view of the Presidential Order dated June 27	 331(b) 1975 promulgated under clause (1) of article 359 of the Consti tution suspending inter alia Article 14 of the Constitution for the period during which the proclamation of emergency made under clause (I ) of Article 352 of the Constitution on December 3	 1971 and on June 25	 1975 are both in force. For the foregoing reasons	 we do not find any merit in this appeal which is dismissed but in the circumstances of the case without any order as to costs. Counsel for the appellants submits that he may be given time for vacating the premises. We grant time till 31st August 1977 on the undertaking given by the counsel that vacant possession will be given on or before that date. M.R. Appeal dismissed.

The appellants and respondents Nos. 3 to 37 herein	 were allottees of houses in Chandigarh constructed by the State Government for low paid industrial workers under the Industrial Housing Scheme subsidised by the Central Govern ment. The Labour Inspector	 Union Territory	 Chandigarh gave them notices in terms of the proviso to	 rule 4(3) of the Punjab Industrial Housing Rules	 1956	 as amended vide Notification dated November 7	 1972	 to. show cause why their allotments should not be cancelled. The income of each of them exceeded Rs. 350/ per mensem	 which disenti tled them to retain their allotments. The appellants and the said respondents filed a joint petition in the High Court for a writ to quash the amendment to rule 4	 and to restrain the Government from cancelling their allotments and evicting them. The writ petition was dismissed. The appel lants contended firstly	 that rule 4(3) was ultra vires the Punjab Industrial Housing Act	 1956 as it took out industri al workers with income exceeding Rs. 350/ p.m. from the scope of section 2(e) of the Act which defines industrial workers; and secondly	 that the authority competent to make rules u/s 24 of the Act cannot frame rules having retrospec tive effect	 and as the amended rule 4(3) operates retro spectively it is invalid Dismissing the appeal by special leave	 the Court	 HELD: (1) The allotment of accommodation to an industrial worker is not unconditional but is subject to conditions which can be changed unilaterally by the Government from time to time by altering the rules in exercise of the powers conferred on it under section 24 of the Act. Section 24 specifically empowers the State Government to make rules to provide inter alia for the manner of allotment of accom modation and conditions relating to its occupation. The impugned amendment which squarely falls within the purview of the aforesaid provisions of section 24	 was validly made	 and was not ultra vires. [331 G H	 331 (a) C] (2) Section 7 of the Act embodies a deeming provision and gives a mandate to treat a person as an unauthorised occupant not only if he ceases to be an industrial worker under the Act	 but also if being an allottee	 he ceases to fulfil any of the prescribed conditions then in force	 including the one relating to the limit of his income	 and thereby becomes amenable to action under section 9(2) of the Act. [331(a) A B] (3) The proviso to rule 4(3) clearly shows that the allotment of an industrial worker whose income exceeds Rs. 350/ per mensem is to stand cancelled not from the date when his income started exceeding Rs. 350/ per mensem but on the expiry of one month 's notice in writing of the can cellation. The rule is not intended to operate retrospec tively on industrial workers who had been allotted and were in occupation of industrial houses immediately before	 328 the amendment of the Punjab Industrial Housing (Chandigarh First Amendment) Rules	 1972. [331(a) E F] The Court observed The scheme being meant for the benefit of the low paid industrial workers and the number of the houses constructed thereunder being very limited	 the Government could legiti mately evolve the method which it did	 to disentitle indus trial workers whose monthly income was relatively large	 to retain the houses.
