4. When the petitioner’s account was to be settled finally on his retirement, without inquiring into, the fact that the petitioner had deposited all the instalments regularly, the respondents No. 3 and 4 deducted a sum of Rs.42,174/-. Thereafter, the petitioner had inquired why such amount had been deducted. In the process, he came to know that such deposit was made to the Treasury for no reason and he was shown as a defaulter in the loan account maintained by the Tripura Housing and Construction Board. However, after deduction and deposit of the said sum arbitrarily by the respondents No. 3 and 4, the Tripura Housing and Construction Board, Agartala had issued a nodemand certificate dated 27.01.2009 (Annexure A-5 to the writ petition). So far, the loan account is concerned, there is no controversy. This entire writ petition is structured for realization of the said amount of Rs.42,174/- as deducted from the petitioner without any basis or valid demand. Now, it has been fairly admitted by the respondents for lapse or mistake, the instalments were not remitted to the Tripura Housing and Construction Board to adjust the loan account.
