“4.Subsequent to the filing of the writ petition seeking the refund, the Housing Board was willing to confirm the sale, subject to approval from the local body. However, the Commissioner of Villivakkam Panchayat Union had rejected the approval as early as on 13.02.2014 for the reason that the size of the plot is not divisible. Therefore, the layout itself is not approved. It is not possible for the Housing Board to sell the plot to the petitioner and the respondent-Housing Board has to refund the amount. The above mentioned amount is in the hands of the respondent-Housing Board from the year 2013. The respondents could have refunded the amount immediately after the rejection of the approval by the local body. Having failed to do so, the petitioner is entitled to interest, while refunding the said amount, for which, the petitioner has claimed interest of 18% per annum. This Court is of the view that awarding 6% of interest would be appropriate. Accordingly, the second respondent-Housing Board is directed to refund a sum of Rs.11,56,650/- with 6% interest per annum to the petitioner within a period of two weeks from the date of receipt of the said sums till the date of payment.
