Pepsi-Cola Products Philippines, Inc. vs. Pagdanganan

The doctrine of stare decisis bars the relitigation of issues already settled by final judgments in prior cases involving substantially the same facts and legal questions, even without identity or privity of parties. Thus, the correct security code is an essential requirement to claim a prize in the Pepsi "Number Fever" promo.

Petitioners Pepsi-Cola Products Philippines, Inc. (PCPPI) and Pepsico, Inc. (PEPSICO) launched a DTI-approved promotional campaign called "Number Fever" in 1992, where specially marked crowns of their soft drink products contained a three-digit number, a seven-digit security code, and a cash prize amount. Respondents Pepe B. Pagdanganan and Pepito A. Lumahan were consumers who possessed crowns bearing the number "349" with security codes L-2560-FQ and L-3560-FQ. The "349" number was announced as a winner for May 26, 1992, but the security codes held by respondents did not match the official list of winning codes, leading petitioners to refuse redemption.

In 1992, Pepsi-Cola Products Philippines, Inc. (PCPPI) and Pepsico, Inc. (PEPSICO) launched a Department of Trade and Industry (DTI) approved promotional campaign called "Number Fever." The promo involved specially marked crowns and resealable caps containing a three-digit number, a seven-digit alpha-numeric security code, and a cash prize amount. A Mexican consultancy firm, D.G. Consultores, was hired to randomly pre-select winning three-digit numbers with their matching security codes. The mechanics were simple: from February 17 to May 8, 1992, a winning three-digit number would be announced daily, and holders of crowns bearing that number would win the corresponding amount printed on the crown. Due to its success, the promo was extended until June 12, 1992, with 25 new winning numbers pre-selected.

On May 25, 1992, "349" was announced as the winning number for the next day. That same night, reports surfaced of people trying to redeem "349" crowns with incorrect security codes "L-2560-FQ" and "L-3560-FQ." Verification revealed that while "349" was the winning number, the security codes presented did not match those on the official list held in a bank vault. PCPPI issued a statement clarifying that only "349" crowns with the correct security codes would be redeemed at full value, while those with codes L-2560-FQ and L-3560-FQ were non-winning but would be redeemed for P500.00 each as a goodwill gesture until June 12, 1992.

Despite this, respondents Pepe B. Pagdanganan and Pepito A. Lumahan demanded full payment for their "349" crowns bearing the incorrect security codes. Pagdanganan held six crowns claiming P1,000,000.00 each and one claiming P100,000.00, while Lumahan held two crowns claiming P1,000,000.00 and P100,000.00, respectively. When petitioners refused, respondents filed a complaint for Sum of Money and Damages. The RTC dismissed the complaint for lack of cause of action but awarded the P500.00 goodwill per crown. The Court of Appeals reversed, ordering full payment, prompting petitioners to elevate the case to the Supreme Court.

• Stare Decisis: Petitioners argued that the appellate court committed reversible error in disregarding the Court's final pronouncements in prior Pepsi/"349" cases (Mendoza, Rodrigo, Patan, and De Mesa), which ruled that "349" crowns with incorrect security codes are non-winning.
• Essential Requirement of Security Code: Petitioners maintained that the matching security code is an indispensable requirement to claim the prize, as established in the prior cases, and the principle of stare decisis should bar relitigation of this issue.

• Non-Applicability of Stare Decisis: Respondents contended that stare decisis does not apply because the legal rights, facts, applicable laws, issues, and evidence in their case are not exactly the same as those in the prior cases.
• Breach of Contract vs. Specific Performance: Respondents argued that their action was based on Breach of Contract, whereas the prior cases involved complaints for Specific Performance, distinguishing their cause of action from the settled precedents.

• Stare Decisis: Whether the principle of stare decisis bars the relitigation of the issue of liability for "349" crowns with incorrect security codes, given prior rulings in Rodrigo, Mendoza, Patan, and De Mesa.
• Security Code Requirement: Whether the correct security code is an essential requirement to become entitled to the cash prize printed on a "349" bearing crown.
• Goodwill Compensation: Whether respondents are entitled to the P500.00 goodwill compensation per crown.

• Stare Decisis: Yes. The appellate court committed reversible error in failing to heed the Court's final and executory decisions in prior Pepsi/"349" cases, which constitute binding judicial precedents.
• Security Code Requirement: Yes. The correct security code is an essential, critical requirement to become entitled to the amount printed on a "349" bearing crown, as established in prior cases.
• Goodwill Compensation: No. Respondents are not entitled to the goodwill compensation because they rejected the offer, and the offer had already expired on June 12, 1992.

• Stare Decisis: The doctrine of stare decisis et non quieta movere is enshrined in Article 8 of the Civil Code, making judicial decisions part of the legal system. The cases of Mendoza, Rodrigo, Patan, and De Mesa arose from the same "Number Fever" promo debacle, involving the same facts, legal rights, applicable laws, causes of action, issues, and evidence. Because these prior cases attained finality and established that crowns with incorrect security codes are non-winning, the Court is bound to adhere to that principle. Stare decisis does not require identity or privity of parties, and abandonment of the doctrine requires strong and compelling reasons.
• Security Code Requirement: The promo mechanics, duly approved by the DTI, uniformly enumerated three essential elements of a winning crown: (1) the 3-digit winning number; (2) the prize denomination; and (3) the 7-digit alpha-numeric security code. The security code serves not only to detect tampering but also to authenticate the winning number against the official list. Since respondents' crowns bore the incorrect security codes (L-2560-FQ and L-3560-FQ), petitioners' obligation to redeem did not arise.
• Goodwill Compensation: The offer of P500.00 for every non-winning "349" crown was a goodwill gesture that expired on June 12, 1992. Following the ruling in Patan, respondents who consistently refused the offer and filed suit cannot now be compelled to receive the goodwill money, as the offer had long expired.

• Stare Decisis et Non Quieta Movere — The doctrine that courts will adhere to precedents and not unsettle things which are established. Founded on the necessity for securing certainty and stability in the law, it does not require identity of or privity of parties. Applied in this case to bar relitigation of the issue of whether "349" crowns with incorrect security codes are winning, as this was already settled with finality in prior cases involving the same facts and legal issues.

• "The doctrine of stare decisis embodies the legal maxim that a principle or rule of law which has been established by the decision of a court of controlling jurisdiction will be followed in other cases involving a similar situation. It is founded on the necessity for securing certainty and stability in the law and does not require identity of or privity of parties." — This passage defines the scope and rationale of the stare decisis doctrine, emphasizing that it applies even without privity of parties, which was central to binding the respondents to prior rulings.
• "the correct security code is an essential, nay, critical, requirement in order to become entitled to the amount printed on a '349' bearing crown and/or resealable cap." — This is the core holding reaffirmed via stare decisis, establishing the indispensable nature of the security code in the Pepsi "Number Fever" promo.

• Mendoza vs. Pepsi-Cola Products Phils., Inc. and Pepsico, Inc., G.R. No. 153183, 24 July 2002 — Controlling precedent. The Court denied the petition, affirming that the matching security code is a condition precedent to winning the prize.
• Rodrigo vs. Pepsi Cola Products (Phils.), Inc. and Pepsico, Inc., G.R. No. 149411, 1 October 2001 — Controlling precedent. The Court denied the petition, affirming that crowns with incorrect security codes are not winning crowns.
• Pepsi Cola Products (Phils.) vs. Patan, Jr., G.R. No. 152927, 14 January 2004 — Controlling precedent. The Court affirmed the necessity of the correct security code and deleted the award of P500 goodwill money because the offer had expired.
• De Mesa vs. Pepsi Cola Products Phils., Inc., G.R. Nos. 153063-70, 19 August 2005 — Controlling precedent. The Court applied stare decisis based on Mendoza and Rodrigo to dismiss the complaint, as the facts and issues were exactly the same.

• Article 8, Civil Code — Provides that judicial decisions applying or interpreting the laws or the Constitution shall form part of the legal system of the Philippines. The Court relied on this provision to enforce the doctrine of stare decisis, treating its final judgments in prior Pepsi "349" cases as binding judicial precedents.
