Summarize the following court judgment. ivil Appeal No. 1262 (N) of 1978. Appeal by Special leave from the Judgment and Order dated the 4th July	 1978 of the Bombay High Court (Nagpur Bench) in Special Civil Application No. 1957 of 1977. G. L. Sanghi	 B. Datta	 V. A Boby Shyam Mudaliar and B. P. Singh for the Appellant. B. R. Agarwal. P. G. Gokhale and Miss Vijayalakshmi for the Respondent. The Judgment of the Court was delivered by DESAI	 J. Appellant Shri Mansaram son of Shri Chanduram Sharma was serving in the telephone office at Nagpur and was thus 142 holding an office of profit under the Union of India. He took on lease premises on a monthly rent of Rs. 75 per month	 more particularly described in the application made to the House Allotment Officer	 Nagpur by first respondent Shri section P. Pathak	 from the then owner of the premises one Shri Basantrai Sharma. He continued to be in possession even after his retirement from service in 1967. Shri Basantrai Sharma died and there is a dispute between respondents 3 and 4 and Shri Prabhakar about succession to the estate of the deceased Shri Basantrai Sharma. Respondents 3 and 4 claimed to be the legatees under a will of deceased Shri Basantrai Sharma. Respondent No. 1 Shri section P. Pathak made an application to House Allotment Officer	 Nagpur registered as Miscellaneous Case No. 51/A 71(2)/76 77 against the present appellant Mansaram alleging that the appellant had occupied the premises involved in the dispute in contravention of sub cl. (2) of Clause 22 of the Central Provinces and Berar Letting of Houses and Rent Control Order	 1949 ( 'Rent Control Order ' for short)	 in that he occupied the premises to which Chapter III of the Rent Control Order applies without obtaining an order under sub cl. (1) of Clause 23 or Clause 24 or without an assurance from the landlord that the premises are being permitted to be occupied in accordance with sub cl. (2) of Clause 23. To this petition	 respondent 4 Smt. Usha Rani N. Sharma was also impleaded as a respondent but after having once appeared through advocate	 she did not prefer to remain present along with her counsel and the House Allotment Officer proceeded against her ex parte. In the application made by Shri section P. Pathak	 Ist respondent on December 7	 1976	 it was in terms stated that the appellant Shri Mansaram Sharma was a Government servant employed in the telephone department at Nagpur and the appellant has now retired from service and therefore	 is not entitled to retain the demised premises. It was further alleged that the former owner of the premises Shri Basantrai Sharma has died. The premises have been inherited by respondent 4 Smt. Usha Rani N. Sharma and she and the tenant Mansaram Sharma have conspired together and are violating the provision of law by letting Shri Mansaram Sharma to continue to live in the premises. It was further alleged that the appellant Shri section P. Pathak was badly in need of premises and therefore	 the premises may be allotted to him. Appellant Shri Mansram Sharma appeared and filed a written statement inter alia contending that he occupied the premises on the assurance given by the then landlord Shri Basantrai Sharma that 143 the house is being permitted to be occupied in accordance with sub cl. (2) of Clause 23. It was further contended that in a proceeding under the Rent Control Order	 that late Shri Basantrai Sharma	 the deceased landlord	 had sought possession of the premises on the ground of bona fide personal requirement but he had lost the same. It was further alleged that Shri section P. Pathak is a near relation of Shri Basantrai Sharma and that he has been put forward by Smt. Usha Rani N. Sharma for seeking a collusive order. It was further alleged that it is incorrect to say that he occupied the house under any allotment order. It was further stated that since his retirement in July	 1967	 he has been accepted as tenant and therefore	 no proceeding can be taken against him under Clause 28 of the Rent Control Order for alleged contravention of clause 22. The House Allotment Officer held that Shri Basantrai Sharma let out the premises to the appellant in the year 1954 in contravention of clause 22(1) (b) of the Rent Control Order and the appellant occupied the premises in contravention of clause 22(2) of the Rent Control Order and therefore	 he was liable to be evicted under clause 28. It was further held that the appellant had occupied the premises when he was holding an office of profit under the Union of India and now that he has retired	 he is not entitled to continue in the premises and therefore	 also he is liable to be evicted. Accordingly	 the House Allotment Officer by his order dated November 2	 1977 gave a direction to the appellant to vacate the premises within a fortnight from the communication of the order and deliver the possession of the premises to Smt. Usha Rani N. Sharma failing which action will be taken under clause 28(1) of the Rent Control Order. Appellant filed a Special Civil Application No. 1957 of 1977 before the Nagpur Bench of the Bombay High Court. A learned Single Judge dismissed the petition in limine. Hence this appeal by special leave. At the outset	 we must confess that the learned Single Judge was completely in error injecting the petition under article 227 of the Constitution in limine because various points raised by the appellant are such that atleast a reasoned decision by the High Court was a must or atleast a speaking order briefly showing why these contentions did not find favour with the High Court. At one stage	 we were toying with the idea to remit the matter to the High Court but 144 that would merely be further delaying the already over delayed proceedings. Order 22 of the Rent Control Order reads as Under: "22(1) Every landlord of a house situated in an area to which this Chapter extends	 shall (a) within seven days from the date of the extension of this chapter	 if the house is vacant on such date; or (b) within seven days from the date on which the landlord becomes finally aware that the house will become vacant or available for occupation by himself or for other occupation on or about a specified date; give intimation of this fact to the Collector of the district in which the area is included or such other officer as may be specified by him	 in the Form given in the Schedule appended to this Order	 and shall not let or occupy the house except in accordance with sub clause (2) of clause 23." (2) No person shall occupy any house in respect of which this chapter applied except under an order under sub clause (1) of clause 23 or clause 24 or on an assurance from the landlord that the house is being permitted to be occupied in accordance with sub clause (2) of clause 23." Clause 23 provides that within fifteen days from the date of receipt of intimation of vacancy under Clause 22	 the Collector may order the landlord to let the vacant premises to any person holding an office of profit under the Union or the State Government or to any person holding a post under the Madhya Pradesh Electricity Board or to displaced person or to an evicted person and thereupon not withstanding any agreement to the contrary	 the landlord shall let the house to such person and place him in possession thereof immediately	 if it is vacant or as soon as it becomes vacant. There is a proviso to clause 23 which provides that simultaneously while giving intimation of the vacancy	 if the landlord intimates to the Collector that he needs the house which has fallen vacant or is likely to fall vacant for his occupation	 the Collector shall	 if satisfied after due enquiry that the house is so needed	 permit the landlord 145 to occupy the same. This proviso is not relevant for the present purpose. Sub clause (2) of Clause 23 provides that if no order is passed and served upon the landlord within the period specified in sub clause (1)	 he shall be free to let the vacant house to any person. Clause 25 provides that where a person is allotted the premises and is put in possession thereof by an order under clause 23 or 24 A	 his tenancy shall stand terminated amongst others on the date from which he ceases to hold an office of profit under Union or a State Government etc. and such person shall vacate such premises within seven days of such date and the landlord and the tenant shall give the intimation about the same as prescribed in clause 22 to the Collector in respect of such premises. There is a proviso which confers power on the Collector to extend the tenancy by a period not exceeding four months. Clause 28 confers power on the Collector to effectively carry out the duty and obligation cast on him under Chapter III. Clause 28 reads as under: "28.(1) The Collector may take or cause to be taken such steps and use or cause to be used such force as may	 in his opinion	 be reasonably necessary for the purpose of securing compliance with	 or for preventing or rectifying any contravention of this Order or for the effective exercise of such power. " The relevant provisions noticed hereinbefore will show that the landlord is under a statutory duty to intimate the existing or impending vacancy in the premises of which he is the landlord to the Collector (clause 22(1)). The object underlying the provision is to make available residential accommodation to the Collector for allotting the same to a specified class of persons set out in clause 23. This class comprises any person holding an office of profit under the Union or State Government or any person holding a post under the Madhya Pradesh Electricity Board	 or a displaced person or an evicted person. The Collector can allot the premises in respect of which he has received an intimation of vacancy under clause 22	 to anyone belonging to the specified class and none else. The very enumeration of the class would show that these are persons who cannot be left to the vagaries of the law of demand and supply of residential accommodation and they are required to be assisted in this behalf for efficient performance of public service or one who is roofless on account of being a displaced person or evicted person. It may be that at any given point of time	 no one from class for 146 whose benefit power is conferred on the Collector to allot vacant premises may be on the waiting list and therefore	 sub clause (2) of clause 23 permits the landlord to let out such premises in respect of which he has intimated a vacancy to any person if within fifteen days from the date of intimation of vacancy to the Collector	 an order of allotment is not served upon the landlord. As a sequel to the right to obtain allotment on the ground of being holder of office of profit under Union or State Government a corresponding obligation is cast upon such person to vacate the premises as soon as he ceases to hold office or the post which enabled him to obtain the order of allotment. To give full effect to these provisions	 power is conferred on the Collector to take appropriate action to enforce provisions of clauses 22 to 27. The application made by Ist respondent Shri section P. Pathak on December 7	 1976 to the House Allotment Officer complained of appellant not vacating the premises even though he has ceased to hold the office of profit. There was not the slightest complaint that when the appellant entered the premises in 1954	 either he did it under an order of allotment made by the Collector or surreptitiously or in league with the then landlord Shri Basantrai Sharma or in violation of the mandatory requirement of Clause 22. Yet the House Allotment Officer proceeded to enquire as to whether clause 22(1) (b) and 22(2) were contravened when the appellant entered the premises in 1954. The first question that should engage our attention is whether the House Allotment Officer was right in holding that there was any contravention of clauses 22(1) (b) and 22(2) of the Rent Control Order at the time when appellant entered the premises in 1954. It is necessary to focus attention on the contention of the appellant in this behalf. He contended in the written statement that he entered the premises on an assurance from the landlord that the premises were being permitted to be occupied in accordance with sub clause (2) of clause 23	 which permits the landlord to let out the premises to whomsoever he considers proper if he has not received an allotment order from the Collector within fifteen days from the date of the receipt of the intimation of vacancy under clause 22. No record was produced by the applicant before the House Allotment Officer whether Shri Basantrai Sharma	 who was then the landlord and the owner of the house intimated to the Collector that a portion of the house which was then in his occupation was intended to be let out. There is not one word in the order of the 147 House Allotment Officer as to how and in what circumstances Shri Basantrai Sharma	 the then owner let out the premises to the appellant. If a landlord assures an incoming tenant that he has complied with the provisions of clause 22	 the tenant can enter the premises without being charged for having contravened sub clause (2) of clause 22. The legal liability of giving intimation of vacancy is squarely on the landlord as provided by clause 22. If the landlord has given intimation of vacancy under clause 22 and the statutory limit of 15 days for making an allotment order has expired	 the landlord on his own can proceed to let out the premises in respect of which he has sent the intimation of vacancy to anyone he chooses to accept as tenant. In such a situation	 the only duty cast on the tenant is to seek an assurance from the landlord that the premises are being permitted to be occupied in accordance with sub clause (2) of clause 23. The appellant specifically contended that he entered the premises on such an assurance from the landlord. In this state of pleading	 it was incumbent upon the House Allotment Officer to enquire whether deceased Basantrai Sharma had given intimation of vacancy and whether any allotment order was issued within the period of 15 days from the date of the receipt of the intimation of it. If it was found that deceased Basantrai Sharma had given an intimation of vacancy and that no allotment order was issued within 15 days from the receipt of the same and that he gave an assurance to the appellant that the premises are being permitted to be occupied in accordance with sub clause (2) of clause 23	 obviously even if the quondam tenant occupied the premises without an allotment order	 he could not be charged with contravention of sub clause (2) of clause 23. Assuming that landlord Basantrai Sharma gave a false assurance in 1954 to the appellant that the landlord had sent an intimation of vacancy and that no allotment order is secured within fifteen days from the date of intimation of vacancy and accordingly false assurance was given	 the tenant if he bona fide relied upon the assurance emanating from the landlord and is not shown to be in league with the landlord	 he would none the less be protected and cannot be accused of entering premises in contravention of clause 23(2). The House Allotment Officer has recorded no finding on this important point and therefore	 on this short ground his order is liable to be set aside. We however find a greater infirmity in the order of the House Allotment Officer. In the absence of an allotment order being produced by the appellant	 three possible surmises are permissible; 148 They are: (1) Shri Basantrai Sharma never sent the intimation of vacancy	 (ii) that even though he did send the intimation of vacancy and yet he did not receive any allotment order within the prescribed period	 and (iii) that he surreptitiously let out the premises to the appellant after giving him a false assurance that he has complied with clause 22. If the allotment order was in fact issued	 a copy of it would be with the appellant as well it must have been sent to the landlord. There would be an office copy in the file of the case. No such allotment order is forthcoming. In the absence of an allotment order	 before the appellant could be charged with contravention of clause 22(2)	 it was incumbent upon the House Allotment Officer to enquire whether Basantrai Sharma had sent any intimation of vacancy to the Collector as required by clause 22(1) (b). If it was not sent	 could his successor in interest take advantage of his own wrong when Smt. Usha Rani N. Sharma who claims to be the inheritor of the premises deliberately remained absent to help the applicant Shri section P. Pathak	 who is alleged to be a near relation of the husband of Smt. Usha Rani N. Sharma and who is keen to enter the premises by alleging contravention of clause 22(1) (b) nearly 22 years before the commencement of the proceedings. Further the tenant contended that deceased landlord gave him an assurance as required by clause 23(2). In the light of this contention it was obligatory upon the landlord or his successor in interest to prove that no such assurance as claimed by the appellant was ever given to him. Shri S.P. Pathak	 the applicant claims to be a stranger. Original landlord Basantrai Shrama was dead by the time the present proceedings commenced. Her successor in interest Smt. Usha Rani N. Sharma remained absent. Appellant gave evidence that he was given the assurance that the premises were being let out to him in accordance with sub clause(2) of clause 23. And sub clause(2) of clause 22 protects a tenant against charge of unauthorised occupation if he enters premises on the assurance as aforesaid as provided in clause 22(2). The order made by the House Allotment Officer is conspicuously silent on this most relevant question why the allegation of assurance put forward by the appellant was not examined by him and why it was rejected sub silention. The non application of mind by the quasi judicial authority to the most relevant point which goes to the root of the matter completely vitiates the order of the House Allotment Officer	 because once the allegation of assurance canvassed for on behalf of the appellant is accepted	 he is not liable to be evicted on the ground that he entered the premises in contravention of clause 22(2). 149 There is a still further infirmity in the order of the House Allotment Officer. Admittedly	 the appellant entered the premises in 1954. He was then serving in the telephone department which would permit an inference to be drawn that he was holding an office of profit in the Union of India. But in order to attract clause 25 of the Rent Control Order which obligates such holder of the office of profit to vacate the premises on his ceasing to hold the office of profit	 it must be shown that he entered the premises under an order of allotment made by the Collector either under clause 23 or clause 24A. Existence of an order of allotment under clause 23 or clause 24A in favour of a person holding an office of profit under the Union of India or the State Government is a sine qua non before the obligation under clause 25 can be fastened upon him to vacate the premises on ceasing to hold the office of profit which enabled him to get an order of allotment in his favour. In the absence of an allotment order	 it is not open to the House Allotment Officer to draw an inference that the premises were allotted to the appellant because he was holding an office of profit. If there is no order of allotment issued to the appellant on the ground that he is holding an office of profit. The House Allotment Officer had no jurisdiction to call upon him to vacate the premises on the short ground that he has ceased to hold the office of profit. The House Allotment Officer has in terms held that as the appellant has retired in 1967	 and therefore he is not entitled to continue to occupy the premises. This line of reasoning proceeds on the assumption that there was initially an order of allotment in favour of the appellant on the ground that he was holding an office of profit	 the assumption being not borne out by the facts. In the absence of an allotment order	 the House Allotment Officer has no jurisdiction to call upon the appellant to vacate the premises on the short ground that he has ceased to hold the office of profit. What is stated hereinbefore is sufficient to quash and set aside the order of the House Allotment Officer. However	 there is one more aspect of the matter which we cannot overlook. The appellant entered the premises in 1954. There have been numerous proceedings between him and the late Basantrai Sharma who let out the premises to the appellant but no one ever raised the question whether the appellant had entered the premises in contravention of clause 22(2). Till Basantrai Sharma died	 no one raised the controversy about the entry of the appellant in the premises as being unauthorised or in contravention of clause 22. Basantrai Sharma in his life time tried to 150 obtain possession of the premises from the appellant alleging grounds available to him under the Rent Control Order other than unauthorised entry. This would permit an inference that Basantrai Sharma accepted the appellant as his tenant and his tenancy did not suffer from any infirmity. After Basantrai Sharma died	 her successor in interest one Smt. Usha Rani N. Sharma did not raise any controversy about the occupation of the premises by the appellant. One Mr. S.P. Pathak	 a total stranger has come forward to complain about the unauthorised entry of the appellant in the premises. The unauthorised entry according to the appellant was in the year 1954. Appellant retired in 1967. Basantrai Sharma was alive in 1967. If appellant came into the premises because he was holding an office of profit	 obviously Basantrai Sharma would not miss the opportunity to evict the appellant because he was otherwise also trying to do the same thing. Rent was accepted without question from the appellant by Basantrai Sharma till his death and thereafter. Could he be at this distance of time	 thrown out on the ground that his initial entry was unauthorised. To slightly differently formulate the proposition	 could the initial unauthorised entry	 if there be any	 permit a House Allotment Officer	 22 years after the entry	 to evict the appellant on the short ground that he entered the premises in contravention of clause 22(2) ? Undoubtedly	 power is conferred on the Collector to see that the provisions of the Rent Control Order which disclosed a public policy are effectively implemented and if the Collector therefore	 comes across information that there is a contravention	 he is clothed with adequate power to set right the contravention by ejecting anyone who comes into the premises in contravention of the provisions. But when the power is conferred to effectuate a purpose	 it has to be exercised in a reasonable manner. Exercise of power in a reasonable manner inheres the concept of its exercise within a reasonable time. Undoubtedly	 no limitation is prescribed in this behalf but one would stand aghast that a landlord to some extent in pari delicto could turn the tables against the person a who was in possession for 22 years as a tenant. In such a situation	 even though the House Allotment Officer was to reach an affirmative conclusion that the initial entry 22 years back was an unauthorised entry and that failure to vacate premises till 9 years after retirement was not proper	 yet it was not obligatory upon him to pass a peremptory order of eviction in the manner in which he has done. In such a situation	 it would be open to him not to evict the appellant. In this connection	 we may refer to Murlidhar Agarwal 151 and Anr. vs State of U.P. & Ors. wherein one Ram Agyan Singh who came into possession of premises without an order of allotment in his favour as required by sec. 7(2) of the U.P. (Temporary) Control of Rent and Eviction Act	 1947	 was permitted to retain the premises by treating his occupation lawful and this court declined to interfere with that order. No doubt it must be confessed that sec. 7A conferred power on the District Magistrate to take action against unauthorised occupation in contravention of the provisions of the U.P. (Temporary) Control of Rent and Eviction Act	 1947	 but there was a proviso to the section which enabled the District Magistrate not to evict a person found to be in unauthorised occupation	 if the District Magistrate was satisfied that there has been undue delay or otherwise it is inexpedient to do so. There is no such proviso to clause 28 which confers power on the Collector to take necessary action for the purpose of securing compliance with the Rent Control Order. But as stated earlier	 where power is conferred to effectuate a purpose	 it has to be exercised in a reasonable manner and the reasonable exercises of power inheres its exercise within a reasonable time. This is too well established to need buttressing by a precedent. However	 one is readily available in State of Gujarat vs Patel Raghav Natha & Ors. In that case Commissioner exercised suo motu revisional jurisdiction under sec. 211 of the Bombay Land Revenue Code which did not prescribe any period of limitation for exercise of revisional jurisdiction. The Commissioner exercised revisional jurisdiction one year after the Collector made the order which was sought to be revised. The High Court set aside the order of the Commissioner. In the appeal by State of Gujarat	 this Court declined to interfere holding inter alia that the revisional power in the absence of prescribed period of limitation must be exercised within a reasonable time and period of one year was held to be too late. This aspect must be present to the mind of House Allotment Officer before just rushing in on an unproved technical contravention brought to his notice contrived by the successor in interest of the deceased landlord	 and evicting the appellant 22 years after his entry and 9 years after his retirement on the short ground that his entry in the year 1954 was in contravention of clause 22(2). Having examined all the aspects of the matter	 we are satisfied that the order of the House Allotment Officer suffers from numerous 152 infirmities and is unsustainable and must be quashed and set aside as also the order of the High Court dismissing the Special Civil Application No. 1957 of 1977 preferred by the present appellant. Accordingly this appeal succeeds and is allowed and the application made by the first respondent to the House Allotment Officer is dismissed with no order as to costs throughout. H.L.C. Appeal allowed.

The appellant who had taken the premises in question on lease while he was serving as an employee of the Telephone Department	 continued to be in possession of the same after his retirement in 1967. Respondent No. 1 who was allegedly in need of accommodation	 filed an application before the House Allotment Officer praying for allotment of the said premises in his favour on the ground that the appellant had occupied the premises in contravention of cl. 22(2) of the Central Provinces and Berar Letting of Houses and Rent Control Order	 1949 and that respondent No. 4 who had inherited the premises from the original landlord was conspiring with the appellant by letting him continue to live in the premises. Respondent No. 4	 after having once appeared through advocate	 withdrew from the proceedings. The appellant contended that he had not contravened any provision of the Rent Control Order as he had occupied the premises on the assurance given by the then landlord that the house was being permitted to be occupied in accordance with cl. 23(2) thereof	 that the deceased landlord who had tried to obtain possession of the premises during his lifetime on the ground of bona fide personal requirement had failed in the attempt and that he had been accepted as the tenant even after his retirement. The House Allotment Officer rejected the contention and directed the appellant to deliver possession of the premises to respondent No. 4 holding that the appellant was liable to be evicted as the letting out of the premises to him by the landlord and his occupation of the same in 1954	 were in contravention of cl. 22(1) (b) and cl. 22(2) respectively of the Rent Control Order and further	 that having occupied the premises while holding an office of profit under the Union of India the appellant was not entitled to continue to remain in occupation of the premises after his retirement from service. The High Court having dismissed in limine the Special Civil Application filed by him under article 227	 the appellant approached this Court. Allowing the appeal	 HELD:1. According to cl. 22(1) of the C.P. and Berar Letting of Houses and Rent Control Order	 1949	 a landlord is under a statutory duty to intimate the Collector any existing or impending vacancy in the premises of which he is the landlord. The object underlying the provision is to make 140 residential accommodation available to a specified class of persons mentioned in cl. 23 which includes a person holding an office of profit under the Union or State Government or a displaced or an evicted person. The Collector can allot the premises in respect of which he has received an intimation of vacancy under cl. 22	 to anyone belonging to this specified class and none else. The very enumeration of the class would show that these are persons who cannot be left to the vagaries of the law of demand and supply of residential accommodation. It may be that	 at any given point of time	 no one from the specified class may be on the waiting list	 and therefore cl. 23(2) permits the landlord to let out such premises to any person if	 after 15 days from the date of intimation of vacancy to the Collector	 an order of allotment is not served upon the landlord. As a sequel to the right to obtain allotment on the ground of being the holder of an office of profit under Union or State Government	 a corresponding obligation is cast by cl. 25 upon such person to vacate the premises as soon as he ceases to hold the office or the post which enabled him to obtain the order of allotment. The legal liability of giving intimation of vacancy is squarely on the landlord and if he has given such intimation and the statutory limit of 15 days for making an allotment order has expired	 the landlord can proceed to let out the premises to anyone. In such a situation	 the only duty cast on the tenant is to seek an assurance from the landlord that the premises are being permitted to be occupied in accordance with cl. 23(2). [145 E H; 146 A B; 147 B C] In the instant case the order of the House Allotment Officer is conspicuously silent on the most relevant question why the allegation of assurance put forward by the appellant was not examined by him and why it was rejected sub silentio. It was incumbent upon him to enquire whether the deceased landlord had given intimation of vacancy and whether any allotment order had been issued within the period of 15 days from the date of receipt of such intimation. The non application of mind by the quasi judicial authority to this relevant point goes to the root of the matter and vitiates the order. It was obligatory upon respondent No. 4	 who was the successor in interest of the landlord	 to prove that no such assurance had ever been given to the appellant. Instead	 the respondent No. 4 remained absent. Even assuming that the landlord gave a false assurance in 1954 to the appellant	 if the appellant bona fide relied upon such assurance and it was not shown that the appellant was in league with the landlord	 he cannot be accused of entering the premises in contravention of cl. 23(2). The High Court was in error in rejecting in limine the petition under article 227. The points raised by the appellant merited a reasoned decision or	 at least	 a speaking order briefly indicating why the contentions put forward by the appellant did not find favour with the High Court. [148 G; 147 D; 148 H; E; 147 F G; 143 G H] 2. In order to attract cl. 25 which obligates the holder of an office of profit to vacate the premises on his ceasing to hold the office of profit	 it must be shown that he entered the premises under an order of allotment made by the Collector either under cl. 23 or under cl. 24 A. [149 B] In the instant case	 in the absence of an allotment order	 it was not open to the House Allotment Officer to draw an inference that	 the premises were allotted to the appellant because he was holding an office of profit. [149 D] 141 3. Where power is conferred to effectuate a purpose	 it has to be exercised in a reasonable manner and the reasonable exercise of power inheres its exercise within a reasonable time. [150 F] In the instant case	 power is conferred on the Collector by cl. 28 to see that the provisions of the Rent Control Order	 which disclose a public policy	 are effectively implemented and	 therefore	 if he comes across information that there is a contravention	 he is clothed with adequate power to set right the contravention by ejecting anyone who comes into the premises in contravention of the provisions. No limitation prescribed in this behalf. But	 even if the House Allotment Officer were to reach the affirmative conclusion that the initial entry of appellant into the premises 22 years back was an unauthorised entry and that failure to vacate premises till nine years after retirement was not proper	 yet it was not obligatory upon him to pass a peremptory order of eviction in the manner in which he has done. It was open to him not to evict the tenant. [150 E F; G H] Murlidhar Aggarwal & Anr. vs State of U.P. & Ors. 	 ; and State of Gujarat vs Patel Raghav Natha and Ors.	[1970] 1 S.C.R. 335; referred to. The appellant had entered the premises in 1954 and there had been numerous proceedings between him and the deceased landlord; but no one had ever raised the question whether the appellant had entered the premises in contravention of cl. 22(2). This would permit an inference that the then landlord had accepted the appellant as his tenant and his tenancy did not suffer from any infirmity. Respondent No. 4 who is the successor in interest of the deceased landlord did not raise any controversy about the occupation of the premises by the appellant and rent was accepted without question before and after the death of the original landlord. [149 G H; 150 A C]
