The petitioner applied for a flat promoted by the respondent Tamil Nadu Housing Board under the housing scheme under MIG Group. The tentative cost of flat then was Rs.8,57,240/- and he was directed to pay a deposit of Rs.3,42,900/- which he already paid. The balance of the tentative cost of Rs.5,14,340/- was paid by him in installments over a period of 13 years with interest at the rate of 13% per annum. Thereafter, the 2nd respondent issued a letter dated 03.06.2010 which is impugned in this Writ Petition, calling upon the petitioner to pay a sum of Rs.1,95,920/- over and above the money already deposited towards the tentative cost. According to the petitioner, the final cost arrived at by the respondents is excessive and that the respondents being a Governmental agency has charged 25% towards profit instead of 9%. Further, along with the interests he paid a sum of Rs.20,00,000/-. Therefore, the claim made by the 2nd respondent through the impugned letter dated 03.06.2010 is too excessive and is liable to be quashed.
