Supreme Court rules delay interest on defective goods begins when buyer discovers the defect, not when it was delivered.

The Supreme Court ruled that delay interest on goods delivered with defects commences only when the buyer discovers the defect, not upon delivery. The buyer argued interest should start immediately, while the seller contended it began at delivery. The court held that the right to claim interest arises only after the buyer has knowledge of the breach, establishing the discovery date as the starting point.
