J.C. Construction (J.C.) bought steel bars from Matibay Steel Industries (MSI) which is owned by Buddy Batungbacal. J.C. failed to pay the purchased materials worth P500,000.00 on due date. J.C. persuaded its client Amoroso with whom it had receivables to pay its obligation to MSI. Amoroso agreed and paid MSI the amount of P50,000.00. After two (2) other payments, Amoroso stopped making further payments. Buddy filed a complaint for collection of the balance of the obligation and damages against J.C. J.C. denied any liability claiming that its obligation was extinguished by reason of novation which took place when MSI accepted partial payments from Amoroso on its behalf. Was the obligation of J.C. Construction to MSI extinguished by novation? Why?
