Summarize the following court judgment. ivil Appeal No. 1201 of 1976. From the Judgment and Order dated 3.8.76 of the Allahabad High Court in Civil Miscellaneous Writ No. 12204 of 1975. Appellant in person. Dileep Tandon and R.B. Mehrotra for the Respondents. The Judgment of the Court was delivered by NATARAJAN	 J. This appeal by special leave by a tenant is directed against the dismissal of Civil Miscellaneous Writ No 12204 of 1975 by the High Court of Allahabad. The second respondent became the owner of a house bearing Municipal No. 140 (old No. 94 A) in Hewett Road	 Allahabad under a gift deed executed in his favour by his mother in 1945. However even in 1944	 his father had leased the house to the appellant on a monthly rent of Rs.30 which after some years was raised to Rs.35 The house is a three storeyed building and the appellant was residing in the first and second floors and running a drug store belonging to his wife in the ground floor. Some years later the second respondent 's father leased out an adjacent building also to the appellant for being used for the drug store business. In 1967 it became necessary for the second respondent to seek recovery of possession of the house because his elder brother	 with whom he was living	 asked him to find accommodation elsewhere. Therefore the second respondent applied for permission under Section 3 of the U.P. (Temporary) Control of Rent and Eviction Act 1947 (hereinafter referred to as the 1947 Rent Act) to the Prescribed Authority to file a suit for eviction against the PG NO 725 appellant on the ground of urgent and reasonable requirement of the house for his own occupation. The Prescribed Authority rejected the application on November 10	 1967. After the 1947 Rent Act came to be replaced by the U.P. Urban Buildings (Regulation of Letting	 Rent and Eviction) Act 1972 (hereinafter the 1972 Rent Act)	 the second respondent again sought the permission of the Prescribed Authority to file a suit against the appellant but this time he sought for recovery of possession of the leased premises either fully or partially. He averred in the application that since his brother had asked him to vacate his house he had taken up residence in a single room in the house of one Srivastava and was living there in great hardship and as such he wanted to recover possession of his house in its entirety failing which at least a portion of it. The Prescribed Authority refused to grant permission on the ground the application had been made within a period of six months from the commencement of the 1972 Rent Act and hence it was barred by Rule 18(1) of the U.P. Urban Buildings (Regulation of Letting	 Rent and Eviction) Rules	 1972 (hereinafter the Rules). The Appellate Authority	 however	 differed from the Prescribed Authority and granted permission to the second respondent to recover possession of the ground floor portion of the house alone. Thereupon the appellant moved the High Court under Article 226 of the Constitution for issuance of a writ to quash the order of the Appellate Authority but did not meet with Success and hence this appeal by special leave. A few facts may first be noticed before the appellant 's contentions are set out and examined. Admittedly	 the second respondent became the owner of the leased premises in the year 15145 under a gift settlement made by his mother and except the leased building he has no other house. It is also an admitted fact that when the first Application for permission to sue was made	 the second respondent was living with his brother but subsequently he had to move out of that house and take up residence in a single room in a building belonging to one Srivastava. A Commissioner appointed by the Court had inspected the room occupied by the second respondent and found that the second respondent was faced with acute shortage of space and that the bath room and latrine were situated in the ground floor which was in the landlord 's occupation. While the prayer in the first application was for the release Of the entire house	 the prayer in the second application was for release of the whole house or in the alternative for the release of at least a portion of the house. PG NO 726 Coming now to the contention of the appellant	 who is a member of the bar and who appeared in person and argued the case for himself. they were as follows: 1. The application made under the 1972 Rent Act was a second application for release of the house on the same ground of requirement and hence it was barred under Rule 18(1) of the Rules since it had been made within six months from the commencement of the 1972 Rent Act. The High Court 's view that the second application was not barred under Rule 18(1) because it is the circumstances of requirement and not the nature of the requirement that would constitute the ground of eviction is erroneous and unsustainable. The Act and the Rules do not permit the creation of two dwelling units in a building covered by a single tenancy and hence the grant of permission for partial eviction is bad in law. The Appellate Authority has erred in rendering a finding against the appellant in the matter of comparative hardship merely because the appellant had another building adjacent to the leased premises for running the drug store. In any event	 the Appellate Authority and the High Court have failed to notice that without the ground floor	 the first and second floors cannot be used as residence because the bath and toilet rooms are situated only in the ground floor. 'The learned counsel for the second respondent. besides refuting the above contentions of the appellant argued that the appeal itself has become unsustainable because the appellant has vacated the building in the year 1976 itself and taken up residence in another house belonging to his wife and consequently by reason of Explanation (1) to Section 21 of the 1972 Rent Act	 he is disentitled to dispute the second respondent 's right to recover possession of the house. We will now consider the contentions of the appellant in seriatum In so far as the first contention is concerned	 it suffers from a fallacy in that it is founded upon a misconstruction of Rule 18 (1) The Rule in question is worded as under: 18. Avoidance of multiplicity of proceedings (Section 38(4) and 41) (l) Where an application of a landlord against any tenant for permission to file a suit for PG NO 727 eviction under Section 3 of the old Act	 on any ground mentioned in Section 21(1) has been finally allowed or rejected on merits either before or after the commencement of the Act	 whether by the District Magistrate or on revision by the Commissioner or the State Government or under clause (i) or clause (m) of Section 43(2) by the District Judge	 and the landlord instead of filing a suit for eviction makes an application under Section 21 on the same ground within a period of six months from such decision or from the commencement of the Act	 whichever is later	 the Prescribed Authority shall accept the findings in those proceedings conclusive. " (emphasis supplied) Provided that the period during which the operation of any permission as aforesaid is stayed by order ot ' any court or authority shall be excluded in computing the said period of six months (2) . . omitted. On a reading of Rule 18(1)	 it may be seen that the Rule does not prohibit or bar the filing of an application for release of any building on any ground mentioned in Section 21( 1) within a period of six months from the date on which a final order was passed in the previous application made under Section 3 of the 1947 Rent Act or within a period of six months from the commencement of the Act. All that the Rule says is that it a second application is made for release of the house on which permission to sue was sought in the previous application on the same ground within a period of six months from the date of the final order in that application or within six months from the commencement of the Act whichever is later	 the prescribed authority shall accept the findings in those proceedings as conclusive.  The Rule only sets out a rule of presumption to be followed by the Prescribed Authority for dealing with an application for release on the same ground without a sufficient interval of time between the filing of the two petitions The Rule does not mandate that a second application preferred on the same ground within a period of six months from the date of the order in the previous application or from the commencement of the Act must necessarily be dismissed as barred under the Rules. The first contention of the appellant is therefore obviously misconceived and cannot therefore be sustained PG NO 728 In so far as the second contention is concerned	 the appellant is right when he says that the earlier application under Section 3 of the 1947 Rent Act and the later application under Section 21(1) of the 1972 Rent Act should be construed as having been made on one and the same ground viz. bona fide requirement of the premises by the second respondent for his own occupation. The High Court has however taken the view that the ground of eviction in the two applications is not the same because different sets of circumstances would constitute different grounds and such a test is satisfied in this case. We do not think it necessary to go into the question whether the High Court 's view is correct or not because even if we treat the two applications as having been made on the same ground	 the second application would not attract the operation of Rule 18(1). Since the Rule contains only a formula of presumption based on facts	 it goes without saying that the prescription is only of a directory nature and not of a mandatory nature. In this context we may appositely refer to the following passage in Phipson on Evidence (Thirteenth Edition) at pages 4 and 5: "Presumptions are either of law or fact. Presumptions of law are arbitrary consequence expressly annexed by law to particular facts; and may be either conclusive	 as that a child under a certain age is incapable of committing any crime; or rebuttable	 as that a person not heard of for seven years is dead	 or that a bill of exchange has been given for value. Presumptions of fact are inferences which the mind naturally and logically draws from given facts	 irrespective of their legal effect. Not only are they always rebuttable	 but the trier of fact may refuse to mke the usual or natural inference notwithstanding that there is no rebutting evidence. " Besides it is a well known principle that in the interpretation of statutes that where the situation and the context warrants it	 the word "shall" used in a Scction or Rule of a statute has to be construed as "may". The present context is one such where the words "the Prescribed Authority shall accept the findings in those proceedings as conclusive" have to be read as "the Prescribed Authority may accept the findings in those proceedings as conclusive" because the findings are based upon existence of facts. We may now set out the reason as to why the prescription in Rule 18(1) should be construed as only PG NO 729 directory and not mandatory In the first place	 the Rule envisages two kinds of situations	 one of them where the second application is made within an interval of six months from the date on which final orders were passed in the previous application and the other where the second application is made beyond an interval of six months	 which may even go up to several years	 as in this case where the interval was over five years	 but within six months of the Act coming into force. Surely	 the legislature would not have intended that the interval factor in the two sets of situations should be visited with the same consequences by adopting a rigid and inflexible application of the prescriptive guideline given in Rule 18(1) . The second factor is that even if the interval factor is the sole criterion for the application of the formula contained in Rule 18(1)	 the legislature could not have intended that even where drastic changes had taken place subsequent to the disposal of the earlier application	 the prescribed authority should shut his eyes to the realities of the situation and blindly and mechanically apply the formula in Rule 18(1) and reject the second application. To cite a few examples it may be that after the disposal of the first application	 the landlord had been rendered houseless due to the house occupied by him falling down due to decay or heavy rains or being destroyed by fire Could any one say that irrespective of the changes that have taken place	 the findings rendered in the previous application would have the force of relevancy till the period of six months fixed under the Rule has expired? It is	 therefore	 manifest that the rule of presumption enunciated in Rule 18(1) is only to serve as a guideline to be followed by the prescribed authority if he finds the circumstances to remain unchanged and the finding rendered in the earlier application to have relevancy even with reference to the facts set out in the second application the Rule intended to avoid multiplicity of proceeding as the very heading given to the Rule would make it clear It will therefore be inequitable and unrealistic to construe Rule 18 (1) as containing an inexorable legal prescription for rejecting a second application filed within the prescribed time limit solely on the basis of the findings rendered in the earlier application. In this case we have already referred to the fact that after the first application was rejected	 the living conditions ot ' the second respodent had changed materially He had been turned out of his brother 's house and forced to take up residence in a single room belonging to a third party and live there in great discomfort and hardship In the plight in which he was placed	 he was even prepared to accept partial release of the house it ' he could not get release of the entire premises. The long interval of time PG NO 730 between the rejection of the first application and the date of making the second application viz. about five years and the significant changes that had taken place during the interval in the living conditions of the second respondent undoubtedly rendered irrelevant the earlier findings and such being the case the rule of presumption given in Rule 18(1) can have no application or relevance to the second application. Viewed in this manner	 we do not think the Appellate Authority or the High court has committed any error in granting the relief of partial release of the house to the respondent Hence the second contention of the Appellant has also to fail. So far as the third contention is concerned viz. the impermissibility of creating two dwelling units in a single tenanted premises	 the argument fails to note that Section 21(1) provides for an order of eviction being passed against a tenant "from the building under tenancy or any specified part thereof." (Emphasis supplied). We do not therefore find any error in the second respondent being granted the relief of partial eviction. As regards the fourth contention	 it is admitted that the appellant had been given an additional building by the second respondent 's father for being used for the drug store business Since the appellant was using the ground floor in the suit premises only for running his wife 's drug store and was not living there in the Appellate Authority cannot be said to have committed any error in taking the view that in the matter of comparative hardship the second respondent would be the more affected person if eviction was not ordered than the appellant by an order of partial eviction being passed because he had another building and could conveniently shift his business to that building. Coming to the last contention of the appellant viz the unsuitability of the first and second floors for residential purpose without the use of the bath and toilet rooms in the ground floor	 it is open to the appellant to move the Prescribed Authority for directions being given to the second respondent to make suitable provision in the ground floor for the appellant and his family members to have access to and make use of the bath and toilet rooms in the ground floor. As regards the contention of the respondent that the appellant and his wife are now living in a house belonging to the appellant 's wife and as such the appellant is precluded under Explanation (i) to Section 21(1) of the 1972 Rent Act from resisting the second respondent 's suit for eviction	 we are unable to make any pronouncement on it because of lack of evidence in support of that plea and PG NO 731 besides the appellant would say that the house now occupied by him and his wife is the subject matter of a litigation between his wife and her uncle. In the light of our conclusions	 the appeal fails and is accordingly dismissed. There will	 however	 be no order as to costs. R.S.S. Appeal dismissed.

In 1967 the second respondent landlord applied to the Prescribed Authority	 under section 3 of the U.P. (Temporary) Control of Rent and Eviction Act	 1947 for permission to file a suit for eviction against the appellant tenant on the ground of his own requirement because his brother with whom he was living had asked him to find accommodation elsewhere. This application was rejected. After the 1947 Rent Act was replaced by the U.P. Urban Buildings (Regulation of Letting	 Rent and Eviction) Act 1972	 the second respondent again sought the permission of the Prescribed Authority for recovery of possession of the leased premises either fully or partially	 on the ground that he was living in great hardship in a single room in a house. The Prescribed Authority refused to grant the permission on the ground that the application had been made within a period of six months from the commencement of the 1972 Rent Act and hence it was barred by Rule 18 (1) of the U.P. Urban Buildings (Regulation of letting	 Rent and Eviction) Rules	 1972. The Appellate Authority	 however	 granted permission to the second respondent to recover possession of the ground floor portion of the house. The appellant moved a petition in the High Court against the order of the Appellate Authority but did not succeed. Before this Court the appellant contends that(l) a second application on the same ground made within six months from the commencement of the 1972 Act was barred under Rule 18 (1) of the 1972 Rules; (2) the High Court 's view that it is not barred because it is the circumstances of requirement and not the nature of the requirement that would constitute PG NO 722 PG NO 723 the ground of eviction is erroneous and unsustainable (3) the Act and the Rules do not permit the creation of two dwelling units in a building covered by a single tenancy; (4) the Appellate Authority has erred in rendering a finding against the appellant in the matter of comparative hardship; and (5) the Appellate Authority and the High Court have failed to notice the without the ground floor	 the first and second floors cannot be used as residence because the bath and toilet rooms are situated only in the ground floor. Dismissing the appeal	 it was	 HELD: (I) All that Rule 18(1) says is that if a second application is made for release of the house on which permission to sue was sought for in the previous application on the same ground within a period of six months from the date of the final order in that application or within six months from the commencement of the Act	 whichever is later	 'the prescribed authority shall accept the findings in those proceedings as conclusive." [727E Fl (2) Even if the two applications are treated as having been made on the same ground	 the second application would not attract the operation of Rule 18(1) since the Rule contains only a formula of presumption based on facts. The prescription of the rule is only of a directory nature and not of a mandatory nature [728C] (3) In the interpretation of statutes	 where the situation and the context warrants	 the word "shall" used in a section or rule has to be construed as "may". The present context is one such where the words "the prescribed Authority shall accept the findings in those proceedings as conclusive" have to be read as "the Prescribed Authority may accept the findings in those proceedings as conclusive" because the finding are based upon existence of facts. [728(	 H] (4) It will be inequitable and unrealistic to construe Rule 18(1) as containing an inexorable legal prescription for rejecting a second application filed within the prescribed time limit solely on the basis of the findings rendered in the earlier application. [729F] (5) The long interval of time between the rejection of the first application and the date of making the second application viz.	 about five years	 and the significant changes that had taken place during the interval in the living conditions of the second respondent undoubtedly rendered irrelevant the earlier findings. [730A B] PG NO 724 (6) Section 21(1) provides for an order of eviction being passed against a tenant 'From the building under tenancy or any specified part thereof." [730C] (7) It is open to the appellant to move the Prescribed Authority for directions being given to the second respondent to make suitable provision in the ground floor for the appellant and his family members to have access to and make use of the bath and toilet rooms in the ground floor.
