V. Kala Bharathi and others v. Oriental Insurance Co. Ltd., Chittoor
Background
The heirs of an engineering graduate killed in a road accident obtained compensation with twelve per cent interest. During appeals, the insurer made several deposits, which did not cover the complete amount due. The executing court adjusted payments against interest first, but the High Court directed adjustment against principal, substantially reducing the remaining liability.
Decision Breakdown
The Supreme Court allowed the heirs' appeal and restored the executing court's order. Where neither the decree nor an agreement specifies a different allocation, a short payment is applied first to interest, then costs, and finally principal. The procedural rules explaining when interest stops did not reverse that allocation rule. This calculation did not unlawfully award interest on interest. After adjustment, further interest could run only on the remaining unpaid principal, so the Court required calculation on that balance.
Lesson Learnt
A debtor making partial payment cannot automatically treat the entire deposit as repayment of principal. Unless the decree or parties' agreement says otherwise, accrued interest and costs are cleared first, and future interest runs on the unpaid principal.
