ORDER :- Since common issue is involved in both these writ petitions, they are being disposed of by the following common order. In W.P. No. 7957 of 94, the petitioner challenges the proceedings of the first respondent dated 15-4-93 in W.D.C. No. D5/10747/89, enhancing the building licence fee etc. As a consequential relief, the petitioner also prays for direction to the first respondent to issue building permit for the construction at 115, Nelson Manickam Road, Madras without insisting upon payment of building licence fee etc. 2. In W.P. No. 8106/94, Tamil Nadu Flat Promoters Association challenges the proceedings of the first respondent dated 7-4-94 in W.D.C. No. TP/658/94, enhacing the building licence fee, security deposit fee etc. They also prayed for direction to the respondents from giving effect to the said impugned circular and from levying any security deposit from the members of the petitioner Association as condition precedent for the grant of planning permission for construction of buildings. 3. The case of the petitioner in W.P. No. 7957 of 94 is briefly stated hereunder. According to the petitioner, he is putting up construction at 115. Nelson Manickam Road, Madras consisting of Block. A, B, C, D and E measuring in all 10330 sq. metres. The petitioner has already paid the security deposit demanded by the Madras Metropolitan Development Authority (in short "M.M.D.A.") as condition precedent for the grant of planning permission by furnishing bank gurantee though the said authority had no power to collect the same. Now, by virtue of the impugned circular dated 15-4-93, the first respondent herein-Corporation of Madras, without any authority, has revised the building licence fee. Similar increases have been made in the matter of scrutiny fee/application, building, plans, fees for issue of true copies, search fees etc. Based on such revision, the 2nd respondent has now levied a sum of Rs. 4,69,270/- towards building licence fee and Rs. 270/- for scrutiny charges as condition precedent for grant of building licence. The petitioner had already approached the M.M.D.A. which is the appropriate planning authority and has complied with all the requirements of the M.M.D.A. for grant of planning permission including the security deposit. On enquiry, the petitioner came to know that the decision of the Corporation was made due to increase in cost of living index. The petitioner had already approached the M.M.D.A. which is the appropriate planning authority and has complied with all the requirements of the M.M.D.A. for grant of planning permission including the security deposit. On enquiry, the petitioner came to know that the decision of the Corporation was made due to increase in cost of living index. This is not at all a justification because there is no services whatsoever rendered by the Corporation in charging the exorbitant fee under the caption "Building Licence fee", because in cases like the petitioner it is the M.M.D.A. which had already granted the planning permission after collecting all the charges. The levy of licence fee by the Corporation of Madras in respect of construction over and above 900 sq. m. and special buildings is clearly illegal. On 17-7-87 the Corporation of Madras further enhanced the building licence fee. On 31-7-92, another order was passed in the form of circular enhancing the levy of building licence fee by several manifolds as well as scrutiny fee and for issuing true copies etc. On 15-4-93 again the rates were increased steeply as evident from the circular which is now the subject matter of challenge in this writ petition. Inasmuch as such levy is illegal and without the authority of law, the petitioner is constrained to approach this Court challenging the said levy and he has no other effective alternative remedy. 4. In W.P. No. 8106 of 94, the petitioner is the Tamil Nadu Flat Promoters Association. According to them, it is a registered Association and it has been formed with the object of promoting the interests of organised development of residential flats in the City of Madras and other parts of the State. It is stated that construction and regulation of any type of building in the City of Madras over and above 900 sq. m. and special buildings is regulated by the Madras Metropolitan Development Authority constituted under the Town and Country Planning Act. In respect of buildings less than 900 sq. m. building licences are to be obtained from only the Corporation of Madras. The M.M.D.A. grants planning permission for development of any land or building in the Madras Metropolitan area in terms of S. 49 of the Tamil Nadu Town and Country Planning Act (hereinafter referred to as "the Planning Act"). In respect of buildings less than 900 sq. m. building licences are to be obtained from only the Corporation of Madras. The M.M.D.A. grants planning permission for development of any land or building in the Madras Metropolitan area in terms of S. 49 of the Tamil Nadu Town an
