Mondragon International Philippines v. Josephine Blanco

Summary

Josephine Blanco, a fashion consultant, won a Toyota Corolla in Mondragon's sales raffle after submitting four fully-paid sales invoices. Mondragon refused to award the prize upon discovering she had other unpaid accounts unrelated to her raffle entry. The RTC dismissed her specific performance suit, but the Court of Appeals reversed, finding the raffle rules only disqualified entries based on unpaid accounts related to the specific raffle submission. The Supreme Court affirmed, applying literal contract interpretation and estoppel principles. The Court ruled that allowing her to participate through issuing an entry form estopped Mondragon from later claiming disqualification. This case establishes important precedent on contract interpretation in promotional contests and the application of estoppel in commercial relationships.
