“ 12. It is also the admitted case that no demand for the said amount was made by the appellants till July, 2001. The said demand having not been made till such time, the appellants are not entitled to claim interest from March, 1993 to July, 2001. In the affidavit filed in support of the stay petition in W.A.M.P.No.5600 of 2004, though it is stated that the allotees were asked to pay the difference amount, the date of demand is not mentioned. The demand in writing was made only on 30.7.2001. The mistake committed by the officials of the appellants department in not demanding the amount till the end of July, 2001, cannot be put against the allotees and therefore the appellants are not justified in claiming interest from March, 1993 to July, 2001. The demand was made on 30.7.2001 and the respondents challenged the same before this Court by filing writ petition. The said writ petition was allowed by the learned single Judge on the premise that several persons were given sale deeds by the appellants without collection of capitalisation fee and interest. The same was explained by the appellants by filing additional counter affidavit in this writ appeal, wherein it is clarified that the registration of the sale deeds to certain persons are by bona fide mistake and the said mistake was found during audit and the persons, who are responsible for the said mistake are being proceeded departmentally and that the persons, who were given sale deeds are also directed to pay difference amount with interest. Hence the allegation of discrimination is found against the respondents.
