construction which according to the petitioners was only in April 2000 that attracts tax under the Building Tax Act. Therefore, petitioners obviously are liable for payment of building tax and luxury tax. However, the demand of luxury tax for the year 19992000 is not tenable because construction of building was completed, even according to the petitioners which is accepted by the 1st respondent, in April 2000. In the circumstances, this writ petition is disposed of declaring petitioners' liability for luxury tax only from 2000-01 onwards with direction to the 1st respondent to recover the tax accordingly. Petitioners are granted three equal monthly instalments to clear the arrears, first of which will be paid on or before last date of September, 2007 and balance two instalments on or before last date of two succeeding months.
