Summarize the following court judgment. pecial Leave Petitions (Civil) Nos. 5678 79 of 1987. 990 From the Judgment and Order dated 8.4.1987 of the Cal cutta High Court in F.M.A.T. Nos. 2256 and 1350 of 1986. S.R. Srivastava for the Petitioners. Tapas Ray	 Somnath Chatterjee	 Sushil Kumar Jain	 B.P. Singh and A. Misra for the Respondents. The Order of the Court was delivered by SEN	 J. These special leave petitions are directed against a judgment and order of a Division Bench of the High Court of Calcutta dated April 8. 1987 upholding the judgment and order of a learned Single Judge dated July 17	 1986 dismissing the petition filed by the petitioners under article 226 of the Constitution. By the writ petition the petition ers had challenged the legality and propriety of the grant of licence by the Calcutta Municipal Corporation of the subsoil of Satyanarayan Park to respondent No. 14 Messrs Happy Homes & Hotels Private Limited for a period of 30 years for the implementation of a development scheme	 name ly	 construction of a two storeyed airconditioned under ground basement market and parking place on mani fold grounds inter alia that the construction of the said under ground market would affect the ecological balance because the park was situate in a densely populated area like Burra bazar in the Metropolitan City of Calcutta	 that the con struction would effect traffic jams in or about the said area leading to a further ecological imbalance and that the Corporation had no authority to grant the licence of the subsoil of the park for the implementation of any develop ment scheme which was not for the development of the park by way of a proper and adequate or proper utilisation of such park. In a considered judgment	 the learned Single Judge (Umesh .Chandra Banerjee	 J.) repelled the contentions advanced on behalf of the petitioners. He considered the questions in depth and held that the grant of licence of the subsoil of Satyanarayan Park for construction of the under ground market would not destroy its intrinsic character as a park and the implementation of the development scheme by the Municipal Corporation was a bona fide exercise of its statu tory powers. The contention regarding ecological imbalance has been negatived by the learned Single Judge as being based on an erroneous assumption of facts	 observing: "The contention of ecological imbalance	 in my view	 is wholly on an erroneous assumption of facts. It is not that there will be no Park as such a Park would be there	 the 991 children 's playground would be there and all the other amenities which a modern Park en joins would be provided for. The difference being whereas the existing one is on the ground level	 after the completion of the project the park will be on an elevated level. Incidentally	 it is to be recorded that Satya Narayan Park for about a decade is in a de plorable state and excepting there being some tall trees	 there was no maintenance of the park as a park by the Corporation Authorities. The contention that greenery would be lost in the Park cannot also be accepted. There was not a blade of grass on the Park. The impor tance of a green spot in a highly congested area like Burrabazar cannot be disputed but the continuation of the project would not	 in the facts and circumstances of the case and as appear from record affect such a green spot. On the contrary	 it would ensure the creation of such a green belt. " Agreeing with the learned Single Judge	 a Division Bench (Chittatosh Mookerjee	 CJ and Amarendra Chandra Sen Gupta	 J.) dismissed the appeal preferred by the petitioners. According to the learned Judges	 there were no allegations of mala fides and there was no doubt whatever that the Municipal Corporation acted in bona fide exercise of its statutory powers under the Act to grant the licence of the subsoil of Satyanarayan Park for the construction of the underground market and therefore the Court ought not to strike down the action of the Municipal Corporation as ultra vires under section 353(2) of the Calcutta Municipal Corporation Act	 1980. They further held that they were unable to sub scribe to the restricted construction placed on behalf of the petitioners that the expression 'development work ' in section 353(2) read with the Explanation thereto can only mean development work either underground or on the surface of the park qua development of the park i.e. for the development and improvement by way of proper and adequate or better utilisation of any such park. In these petitions	 two questions mainly arise	 namely: (1) Whether the grant of licence by deed of licence dated February 15	 1985 by the Municipal Corporation in favour of respondent No. 14 Messrs Happy Homes & Hotels Private Limit ed of the subsoil of Satyanarayan Park in the Burrabazar area of the Metropolitan City of 992 Calcutta for implementation of a development scheme	 namely	 to build and construct a two storeyed underground aircondi tioned basement market	 and to hold the said market for a period of 30 years from the date of execution of the deed on payment of a premium of Rs.30 lakhs and a licence fee of Rs.40	000 per month on condition that the licensee shall at its own cost relocate and maintain the park on the top of the said market for augmenting and improving amenities to the citizens which shall always remain as a public park belonging to the Municipal Corporation	 was in breach of its statutory powers under sub section (2) of section 353 read with the Explanation thereto of the Calcutta Municipal Corporation Act	 1980. (2) Should the expression 'development work ' in section 353(2) of the Act read with the Explanation thereto be construed to mean development work qua the park i.e. such development work must be confined to the proper and better utilisation of the park? Shri Shanti Bhushan	 learned counsel for the petitioners assails the action of the Municipal Corporation substantial ly on two grounds: (1) The Municipal Corporation has no power to alienate or part with possession of any public street	 park	 square or garden or the subsoil thereof for the purpose of implementation of any development work. The Corporation being a creature of the statute must function within the four confines of the Act creating it and in the absence of any provision for the conferral of such a power	 it had no authority to grant a licence of the subsoil of Satyanarayan Park for the purpose of construction of the underground market. (2) On a true construction of sub s.(2) of section 353 read with Explanation thereto the development work either underground or on the surface of a public street	 park	 square or garden must be for development and improve ment by way of proper and adequate or better utilisation of any such public street	 park	 square or garden. The learned counsel placed reliance on the decision in Attorney General vs Corporation of Sunderland LR	 [187576] for the submission that the position of the Municipal Corpora tion in regard to public parks	 gardens	 squares and streets under the Act was that of a trustee and the Corporation would be guilty of breach of trust in employing any part thereof for purposes other than those contemplated by the Act. In reply Shri Somnath Chatterjee	 learned counsel ap pearing for respondent No. 14 Messrs Happy Homes & Hotels Private Limited contended that the grant of licence by the Municipal Corporation of the subsoil of Satyanarayan Park was a bona fide exercise of its statutory powers and the construction of the underground market would 993 not destroy its intrinsic character as a park and there was no warrant	 as the High Court has held	 to give a restric tive meaning to the expression 'development work ' in section 353(2) of the Act read with the Explanation thereto. At the hearing	 the learned counsel drew our attention to the supplementary affidavit filed on behalf of his client dated July 25	 1987 showing that the structural work of the under ground market has been completed and the concrete roof has been laid. All that remains is the laying of a park. It appears therefrom that the value of the work done so far is Rs.2.30 crores out of the estimated cost of Rs.4.51 crores and that the underground airconditioned market is likely to be commissioned within a couple of months. It also appears that respondent No. 14 has entered into a contract with Joshi & Associates	 Architects for re development and re laying of Satyanarayan Park as a terrace ' garden. The letter of the Agri Horticultural Society of India dated July 24	 1987 gives a detailed scheme for such re location of the park as a terrace garden with tall trees. It provides for laying of a spacious lawn admeasuring about 12	000 square feet .with replantation of fast growing tall trees and dwarf trees	 laying of shrubs etc. The material on record clearly shows that the intrinsic character of Satyanarayan Park as a public park would not be destroyed by the construction of the underground market which with its raised height at 6 feet from the road level is to have a terrace garden with tail trees all around and it would remain a place of recrea tion. This dispels the contention of Shri Shanti Bhushan based on Attorney General vs Corporation of Sunderland that the construction of the underground market would destroy the intrinsic character of Satyanarayan Park as a park. Under the scheme there would be no construction on the park; the underground market would be under the park and not over the park. The only difference is that the park would be re located at a height of 6 feet above the road level easily accessible by three separate staircases. Under the scheme	 Satyanarayan Park would become a real park with a lush green garden with tall trees	 shrubs etc. and a centre for relaxa tion of the thickly congested Burrabazar locality and in particular for the children as a playground. It is signifi cant that the Division Bench has issued a writ of mandamus commanding the respondents to restore Satyanarayan Park as a public park as stipulated in the deed of licence dated February 15	 1985 and to maintain it as a public garden. Shri Somnath Chatterjee has drawn our attention to the finding of the learned Single Judge that the development scheme would not create any ecological imbalance. On the contrary	 the implementation of the scheme would ensure the creation of a green belt. It was conceded before the learned Single Judge that the terrace garden with 994 green grass would be laid on the upper basement of the underground market. As regards the apprehension expressed by Shri Shanti Bhushan that tall trees would disappear from the park	 it is enough to say that the learned Single Judge has in his judgment observed that there is no basis for this apprehension at all. He records that as a matter of fact	 replantation of tall trees has already been effected in terms of the earlier order passed by the Division Bench under the expert supervision of the Agri Horticultural Society of India. Thus	 there would be a 'patch of green ' in the thickly congested Burrabazar area which would tend to improve	 rather than retard	 ecological balance and there would be a place of recreation for all and in particular for the children as a playground. In the facts and circumstances of the case	 the High Court was justified in holding that the implementation of the development scheme would squarely fall within the ambit of sub s.(2) of section 353 of the Calcutta Municipal Corporation Act. 1980 and the construction of the underground market is not intended and meant to destroy the intrinsic character of Satyanarayan Park as a public park but on the contrary	 the scheme is to re locate and redevel op the park as a public park as a place for public recrea tion. We find no justification whatever to interfere with the judgment of the High Court. Before parting with the case	 we wish to mention that we impressed upon Shri Somnath Chatterjee	 learned counsel for respondent No. 14 that the grant of a fully airconditioned underground market on a premium of Rs.30 lakhs and a rent of Rs.40	000 per month which was revisable at the end of every 30 years has to be altered. It was clearly against the public interest to grant the market on a rent of Rs.40	000 per month having regard to the spiral rise of rents of commercial premises in all urban areas throughout the coun try. We directed the parties to revise the terms and posted the case for further directions on August 12	 1987. We are happy to record that on that day Shri Chatterjee made a statement that his client is prepared to revise the terms as to the rate of licence fee. He filed an affidavit sworn by Ram Niranjan Kajaria	 Director	 Messrs Happy Homes & Hotels Private Limited giving an undertaking to the following effect: (L) Messrs Happy Homes & Hotels Private Limited shall pay licence fee Rs. 75	000 per month which shall be revisable at the end of every three years. (2) It shall maintain the underground market in proper state of repairs and the airconditioning plant installed therein in proper workman like condition until the expiry or determination of the licence. (3) It shall re locate and re develop Satyana rayan Park as a public park at its own expense as provided in the deed of licence dated 995 February 15	 1985 for which it has entered into a contract with AgriHorticultural Society of India	 Alipore	 Calcutta and it shall maintain properly the said park as a public park throughout the entire period of 30 years. Subject to this modification	 the special leave peti tions are dismissed without any order as to costs. S.L. Petitions dis missed.

The petitioners filed a writ petition in the High Court	 challenging the legality and propriety of the grant of a licence by the Calcutta Municipal Corporation of the sub soil of Satyanarayan Park to respondent No. 14 Messrs. Happy Homes & Hotels Private Limited for a period of 30 years for the implementation of a development scheme	 name ly	 construction of a two storeyed air conditioned under ground basement market and parking place. The High Court (Single Judge) repelled the contentions of the petitioners and dismissed the writ petition. Against the judgment and order of the Single Judge	 the petitioners preferred an appeal before the Division Bench of the High Court. The Division Bench dismissed the appeal. Aggrieved by the deci sion of the High Court	 the petitioners filed petitions for special leave before this Court for relief. Disposing of the petitions	 the Court	 HELD: In these petitions	 two questions mainly arose	 namely	 (i) whether the grant of licence by the Municipal Corporation in favour of respondent No. 14	 Messrs. Happy Homes and Hotels Pvt. Ltd.	 of the sub soil of Satyanarayan Park for the implementation of a development scheme	 namely	 to hold the said market for 30 years on payment of a premium of Rs.30 lakhs and a licence fee of Rs.40	000 per month on certain terms and conditions	 was in breach of its statutory powers under sub section (2) of section 353	 read with the Explanation thereto of the Calcutta Municipal Corporation Act	 1980	 and (ii) should the expression 'development work ' in section 353 (2) of the said Act	 read with the Explanation thereto be con strued to mean development work qua the park	 i.e.	 such development work must be confined to the proper and better utilisation of the park? [991G H; 992A C] 988 Counsel for the petitioners assailed the action of the Municipal Corporation substantially on two grounds briefly stated as (i) The Municipal Corporation had no power to alienate or part with possession of any public street	 park	 square or garden or the sub soil thereof for the purpose of implementation of any development work	 etc.	 and (ii) On a true construction of sub section (2) of section 353	 read with the Explanation thereto	 the development work either underground or on the surface of a public street	 park	 square or gar den	 must be for development and improvement by way of proper and adequate or better utilisation of any such public street	 park	 etc. [992D F] Shri Somnath Chatterjee	 counsel for respondent No. 14	 contended that the grant of licence by the Municipal Corpo ration of the sub soil of Satyanarayan Park was a bona fide exercise of its statutory powers	 and the construction of the underground market would not destroy its intrinsic character as a park and there was no warrant to give a restrictive meaning to the expression 'development work ' in section 353(2) of the Act	 read with the Explanation thereto. He drew attention of the Court to a supplementary affidavit filed by his client	 showing that the structural work of the underground market had been completed and the concrete roof had been laid	 and all that remained was the laying of a park. It appeared therefrom that the value of the work done so far was Rs.2.30 crores out of the estimated cost of Rs.4.50 crores	 and the underground air conditioned market was likely to be commissioned within a couple of months	 and also that the respondent No. 14 had entered into a contract with Joshi & Associates	 Architects	 for the re development and relaying of the Satyanarayan Park as a terrace garden; a letter of the Agri Horticultural Society of India gave a detailed scheme for such re location of the park as a ter race garden	 etc. [992H; 993A C] The material on record clearly showed that the intrinsic character of the Satyanarayan Park as public park would not be destroyed by the construction of the underground market which with its raised height at 6 feet from the road level was to have a terrace garden. Under the scheme	 there would be no construction on the park; the underground market would be under the park and not over the park	 and the Satyanaray an Park would become a real park with a lush green garden	 tail trees and shrubs	 etc. It was significant that the Division Bench had issued a writ of mandamus commanding the respondents to restore Satyanarayan Park as a public part as stipulated in the deed of licence and to maintain it as a public park. The High Court (Single Judge) gave the finding that the development scheme would not create any ecological 989 imbalance	 but would ensure the creation of a green belt. There would thus be a 'patch of green ' in the thickly con gested Burrabazar area which would tend to improve the ecological balance and provide a place of recreation for all. [993D G; 994A C] In the facts and circumstances of the case	 the High Court was justified in holding that the implementation of the development scheme would squarely fall within the ambit of sub section (2) of section 353 of the Calcutta Municipal Corpora tion Act	 1980 and the construction of the underground market was not intended and meant to destroy the intrinsic character of the Satyanarayan Park as a public park; on the contrary	 the scheme was to re locate and re develop the part as a public park. There was no justification whatever to interfere with the judgment of the High Court. [994C D] The Court directed that the grant of a fully air condi tioned market on a premium of Rs.30 lakhs and a rent of Rs.40	000 per month	 which was revisable at the end of 30 years had to be altered. It was clearly against the public interest to grant the market on a rent of Rs.40	000 per month	 having regard to the spiral rise of rents of commer cial premises in all urban areas. The Court directed the parties to revise the terms and posted the case for further directions on August 12	 1987. On that day	 Shri Som Nath Chatterjee filed on affidavit on behalf of his client	 giving an undertaking to the following effect: (1) M/s. Happy Homes & Hotels Pvt. Ltd. shall pay licence fee @Rs.75	000 per month which shall be revisable at the end of the every three years; (2) It shall maintain the underground market in proper state of affairs and the air conditioning plant therein in proper workman like condition until the expiry or determination of the licence; (3) It shall re locate and re develop Satyanarayan Park as a public park at its own expense as provided in the deed of licence for which it has entered into a contract with Agri Horticultural Society of India	 and it shall maintain properly the said park as a public park throughout the entire period of 30 years. [994E H; 995A] The Special Leave Petitions were dismissed subject to this modification. [995B] Attorney General vs Corporation of Sunderland LR 	 referred to.
