Venugopal	 A.K. Sen	 M.K. Nesari	 P.H. Parekh and R.K. Dhillon for the petitioners. F.S. Nariman	 U.J.Maskeja	 B.S. Basaniaum	 J. Peres	 A.K. Verma and D.N. MiShra for the Respondents. The Judgment of the Court was delivered by SABYASACHI MUKHARJI	 J. This petition is for leave to appeal against the judgment and order of the Division Bench of the 485 Bombay High Court dismissing Letters Patent Appeal from the order of the learned Single Judge. The 1st respondents being the trustees for the Port of Bombay are the owners of plot of land bearing Plot No. 62 admeasuring 576 sq. yards Lying and situate in Pooria Street	 Elphinstone Estate	 Bombay 3. In or about 1945 the trustees of the Port of Bombay granted lease of the said plot of land to one Mustafa Husein for the purpose of erecting a godown for carrying on commercial activities at a monthly rent of Rs. 925 which later on was increased to Rs.1	465. In or about 1946 Mustafa Husein being the lessee of the 1st Respondent erected a permanent godown of brick	 mortar and cement. The said Mustafa Husein in 1958 granted lease of the said godown to the petitioners; the area of the godown is about 3	000 sq. It is alleged that petitioners have since been carrying on their business in the said godown The Trustees of the Port of Bombay filed suit against the heirs of Mustafa Husein for eviction from the lease granted to Mustafa Husein for termination of the tenancy. The ground for eviction was termination of tenancy. The Trustees of the Port of Bombay in July	 1977 obtained a decree on admission against the heirs of Mustafa Husein in the said suit. In or about May	 1985 warrant of possession in execution of decree dated 20th of July	 1977 was sought to be executed against the petitioners. The petitioners obstructed the execution of the decree. Thereupon in or about June	 1985	 the Trustees of the Port of Bombay took out a Chamber Summons in the High Court of Bombay for removal of obstruction under order 21 Rules 97 to 101 of the Code of Civil Procedure. Petitioners contended that they were lessees under the said Mustafa Husein and as such they were entitled to the protection of the Bombay Rent	 Hotel and Lodging Houses Rates (Control) Act	 1947	 hereinafter called the Bombay Rent Act	 as the Bombay Rent Act applied to the building erected by a lessee from the local authority and as such the petitioners right of possession was protected under the provisions of the Bombay Rent Act. The Trial Court allowed the Chamber Summons and rejected the petitioner 's contentions. He observed that it was not necessary to record evidence in this case. The petitioners being aggrieved preferred a first appeal. The learned single judge of the High Court dismissed the first appeal holding that the petitioners were not entitled to the benefit of the Bombay Rent Act and negatived the contentions arising out of the Easement Act and also arising out of the alleged acquiescence of the Trustees of the Port of Bombay. The petitioners preferred Letters Patent Appeal which was also dismissed by the Division Bench of the Bombay High Court. The High Court observed that if the contentions of the petitioners were accepted then the provisions of Section 4(1)(a) of the Bombay Rent Act would become nugatory. Being aggrieved 486 therefrom the petitioners seek leave to appeal to this Court under A Article 136 of the Constitution. The question	 is	 whether the petitioners are entitled to protection under section 4(1)(a) of the Bombay Rent Act. The answer will depend upon the question whether there was any building lease granted to the original tenant Mustafa Husein. There was none	 at least no such evidence was adduced before the learned Trial Judge or before the Division Bench of the High Court. When the matter came before this Court for admission by our order dated 17th of September	 1987 as the question involved was whether there was any agreement or lease with the lessor that they will have to construct building on the land demised to them	 but as no such lease had been produced so far	 time was granted for production of such evidence. Pursuant to the same today we have been shown two letters	 one dated 16th of April	 1951 written by the Architect of the lessor forwarding the plants in triplicate to the Bombay Port Trust for approval	 and the other letter dated 14th of June	 1951 written by the Manager	 Land and Bunders to the architect of the lessor on the following subject: "Elphinstone State Reconstruction of a Shed on Monthly Tenancy Plot at Poona Street. " The petitioners were informed that the plan was approved subject to the compliance of the Municipal Regulations. This question arose in the Bombay High Court in Ram Bhagwandas vs Municipal Corporation of the City of Bombay	 There interpreting the Bombay Rent Act and section 4(1) and 4(a) thereof Chief Justice Chagla speaking for the Division Bench held that the proper interpretation to put upon section 4(4)(a) was that "under an agreement	 lease or grant" must qualify both "building erected" and "land held". In other words	 the building must be erected by the lessee pursuant to the agreement	 lease or grant given to the person who held the land under that agreement	 lease or grant. Therefore	 where a building was erected by the lessee not pursuant to any agreement with the lessor or not under any agreement with the lessor then the case did not fall under section 4( l)(a). What section 4(1) does is to give immunity to the local authority in respect of the land which it has let out to the lessee and that immu 487 nity cannot be taken away merely because the lessee on his own volition and without being under any obligation under any agreement choses to put up structures on that land. Section 4 deals with exemptions and sub section (1) provides as follows: "This Act shall not apply to any premises belonging to the Government or a local authority or apply as against the Government to any tenancy or other like relationship created by a grant from the Government in respect of premises taken on lease or requisitioned by the Government: but it shall apply in respect of premises let to the Government or a local authority". Therefore	 if we have premises which belong to Government or a local authority	 then the Act would not apply. The land here belongs to the local authority but the structures were put on by the lessees of the Port not under any building lease	 and such protection can not be claimed in respect of these premises. Sub section (4)(a) of section 4 is also relevant. It was held "The expression 'premises belonging to the Government or local authority ' in sub section (1) shall	 notwithstanding anything contained in the said sub section or in any judgment decree or order of a Court not include a building erected on any land held by any person from the Government or a local authority under an agreement	 lease or other grant	 although having regard to the provisions of such agreement	 lease or grant the building so erected may belong or continue to belong to the Government or the local authority	 as the case may be". Chief Justice Chagla considered the historical background under which Section 4(a) was enacted by the Bombay Act of 1953. This decision was approved by this Court in Kanji Manji vs The Trustees of the Port of Bombay [1962] Suppl. 3 S.C.R. 461. Sub section (4)(a) and (b) read as follows: "(4)(a). The expression "premises belonging to the Government or a local authority" in sub section (1) shall	 notwithstanding anything contained in the said sub section or in any judgment	 decree or order of a Court	 not include a building erected on any land held by any person from the Government or a local authority under an agreement	 lease or other grant	 although having regard to the provisions of 488 such agreement	 lease or grant the building so erected may belong or continue to belong to the Government or the local authority	 as the case may be; and (b) notwithstanding anything contained in section 15	 such person shall be entitled to create a tenancy in respect of such building or a part thereof." This Court observed at page 471 of the report that this was introduced by amendment and the purpose of the amendment was as follows: "The amendment achieved two different things. It enabled the lessee of the particular kind of building described in cl.(a) to create sub tenancies in spite of the ban against sub tenancies contained in section 15. It also excluded from the operation of sub section (1) the buildings specified in cl. (a) of the sub section. The amendment said nothing about the relationship of the Government or the local authority	 on the one hand	 and the lessee	 on the other	 in respect of the land. The word "premises" in sub section (1) could mean the land or the buildings or both. Sub section (4)(a) dealt only with the buildings	 and did not deal with the land	 because it used the word "buildings" and not the more general word "premises". The import of sub section (4)(a) of section 4 was thus limited to buildings	 and did not extent to land. The sub section	 however	 was drafted somewhat in artistically	 and the obscurity of the language presents some difficulty. The Trial Judge followed a decision of the Bombay High Court reported in Ram Bhagwandas vs Bombay Corporation In that case	 one Khudabaksh Irani had taken lease of certain plots some 30 years back	 and constructed some structures upon the open plot	 and rented them out as tenements. In 1947	 Irani sold them to one Tyaballi. In 1951	 the Municipal Corporation filed a suit to eject Tyaballi from the plots	 and by a consent decree	 Tyaballi agreed to deliver up vacant and peaceful possession of the plots clear of all structures. Tyaballi failed to remove the structures	 and the Municipal Corporation sought to execute the decree. The tenants thereupon filed a suit under 0.21	 r. 103 of the Civil Procedure Code against Municipal Corporation	 but the h suit was dismissed. In the appeal which was filed in the 489 High Court	 it was conceded that the Municipal Corporation was the owners of the plots in question	 but protection was claimed on the basis of sub section (4)(a) of section 4 of the Rent Control Act. Chagla	 C.J. in dealing with the history of the amending Act	 pointed out that the legislature was seeking to protect by that sub section tenants who occupied buildings put upon land belonging to a local authority	 if the buildings occupied by them were constructed under an agreement under which the lessee was under an obligation to construct buildings. He pointed out that the protection of sub section (4)(a) was to buildings and not to land	 and that the phrase "under an agreement	 lease or other grant" modified not only "held by any person from Government or local authority" but also "erected on any land". therefore	 held that the words "erected on any land held by any person form a local authority" were descriptive of the building and did not emphasise the point of time when the building was erected. By that phrase	 what was emphasised was "that the nature of the building must be such as to satisfy the test that it was erected on land held by a person from a local authority and the test must be applied at the time when the protection is sought." In that case	 it was contended before this Court	 as it was contended in the Bombay High Court	 that so long as a building was erected under an agreement with Government or a local authority	 the benefit of sub section (4)(a) of section 4 would be available	 no matter how many hands the property might have changed. This Court accepted the interpretation of the High Court in the aforesaid decision. In our opinion	 in the instant case	 in view of the fact that the original lease was only a monthly tenancy and not a building lease	 the High Court was right in dismissing the objections on behalf of the petitioners. We find no reason	 therefore	 to interfere with the order of the High Court. The special leave petition therefore	 fails and is accordingly dismissed without any order as to costs. Since	 the petitioners have been in possession of the premises for some time	 in the interest of justice it is desirable	 in our opinion	 that the petitioners should have time to vacate the premises in question. In the premises	 we allow the petitioners to continue to remain in the premises upto 15th of September	 1988 provided they file the usual undertaking in this Court within four weeks. N.P.V. Petition dismissed.

In 1945 the first respondent Trustees of Port of Bombay	 granted lease of plot owned by them for the purpose of erecting a godown for carrying on commercial activities at a monthly rent of Rs. 925. In 1946 the lessee erected a permanent godown. In 1958	 he granted lease of the said godown to the petitioners. The first respondent filed a suit against the heirs of the original lessee for eviction on the ground of termination of tenancy	 and obtained a decree. When warrant of possession was sought to be executed	 the petitioners obstructed the execution of the decree. The first respondent thereupon took out a Chamber Summons for removal of obstruction under order 21 Rule 97 101 C.P.C. The petitioners contended that as they were lessees under the original lessee they were entitled to protection of the Bombay Rent	 Hotel and Lodging Houses Rates (Control) Act	 1947 the Bombay Rent Act which applied to the building erected by a lessee from the local authority. The trial court rejected the petitioners ' objection and allowed the Chamber Summons. The appeal of the petitioners was dismissed by the Single Judge of the High Court holding that they were not entitled to the benefit of the Bombay Rent Act. The contentions arising out of the Easement Act and alleged acquiescence of the first respondent were negatived. The Letters Patent Appeal was also dismissed by the Division Bench. On the question whether the petitioners were entitled to protection under section 4(1)(a) of the Bombay Rent Act. 484 dismissing the Special Leave Petition	 ^ HELD: Where a building was erected by the lessee not pursuant to or not under any agreement with the lessor then the case did not fall under section 4(1)(a) of the Bombay Rent	 Hotel and Lodging Houses Rates (Control) Act	 1947. [486G] Section 4(1) gives immunity to the local authority in respect of the land which it has let out to the lessee and that immunity cannot be taken away merely because the lessor on his own volition and without being in obligation under any agreement choses to put up structures on that land. Therefore	 if the premises belonged to the Government or a local authority then the Act would not apply. [486H; 487A	 D] In the instant case	 The lands belong to the local authority but the structures were put on by the lessees of the first respondent not under any building lease	 and such protection cannot be claimed in respect of these premises. In view of the fact that the original lease was only a monthly tenancy and not a building lease	 the High Court was right in dismissing the objections on behalf of the petitioners. Since the petitioners have been in possession of the premises for some time	 the petitioners are allowed to continue to remain in the premises upto 15th September	 1988. [489F	 H] Kanji Manji vs The Trustees of the Port of Bombay	 [1962] Suppl. 3 S.C.R. 461 applied.
