De Mesa vs. Pepsi Cola Products Phils., Inc.

The doctrine of stare decisis, as embodied in Article 8 of the Civil Code, requires courts to follow rules already established in final Supreme Court decisions, and where the legal rights, facts, applicable laws, causes of action, issues, and evidence in a subsequent case are identical to those in a previously decided case, the prior ruling is binding and bars further relitigation.

Petitioners are holders of soft drink bottle caps bearing the number "349," allegedly a winning combination in the "Number Fever" contest sponsored by respondents Pepsi Cola Products Phils., Inc. (PCPPI), a domestic corporation engaged in the production, bottling, and distribution of carbonated drinks, and PEPSICO, Inc. (PI), a foreign corporation licensed to do business in the Philippines and the major stockholder of PCPPI. The promotion involved pre-selecting winning numbers through D.G. Consultores, a Mexican consulting firm, with the approval of the Department of Trade and Industry (DTI), which required respondents to deposit the list of winning numbers with corresponding security codes in a bank safety deposit box to prevent tampering.

Petitioners are among the numerous holders of soft drink bottle caps bearing the number "349," which was announced as a winning combination in the "Number Fever" contest sponsored by respondents PCPPI and PI. The promotion was conducted in two periods: the initial period from February 17 to May 8, 1992, during which respondents seeded 1,000 numbers—60 winning, 510 non-winning, and 430 unused—and the extended period from May 10 to June 12, 1992, during which 25 additional winning numbers were predetermined from the list of unused numbers. D.G. Consultores, a Mexican consulting firm, was tasked to randomly pre-select the winning numbers and send respondents a list of 60 winning numbers with corresponding security codes. The selection process was implemented with the approval of the DTI, which required respondents to deposit the list of winning numbers and security codes in a bank safety deposit box to prevent tampering.

On May 25, 1992, respondents announced "349" as the winning number for the May 26 draw. Later that same night, PCPPI's Marketing Services Manager, Quintin Gomez, Jr., called DTI Director Madarang to inform her that, due to security code problems, a mistake had been made in announcing "349" as the winning number. Numerous holders of the supposedly winning "349" crowns were not honored or paid by respondents, prompting these rejected crown holders to file separate complaints for specific performance and damages.

The first complaint, Civil Case No. 93-68351, was filed before the RTC of Manila, Branch 16, but the plaintiffs withdrew, leaving Gerson Mendoza as sole plaintiff in what became the Mendoza case. The other plaintiffs re-filed before the RTC of Manila, Branch 50, as the Rodrigo case, docketed as Civil Case No. 94-71403. Petitioners herein filed their own separate complaints before the RTC of Makati, Branch 142, docketed as Civil Cases Nos. 94-2414 to 94-2421. Both the Mendoza and Rodrigo cases were dismissed by the RTC and affirmed by the Court of Appeals, and the Supreme Court denied the petitions for review. The Rodrigo case became final and executory on February 5, 2002.

Meanwhile, on December 11, 2000, petitioners filed a motion for leave to either adopt the testimonial and documentary evidence in the Mendoza and Rodrigo cases or archive their cases until final resolution of those two pending matters. The RTC granted the motion on January 8, 2001, and the cases were archived. After the Rodrigo case became final, respondents filed a motion to dismiss petitioners' complaints on February 20, 2002, invoking stare decisis. The RTC granted the motion on April 18, 2002, finding that the facts, applicable laws, causes of action, issues, and evidence in petitioners' cases were identical to those in the Rodrigo case, such that the ruling therein was a bar to relitigation. The RTC's factual findings adopted from the prior cases established that respondents did not breach any contract because the "349" crowns with security code "L-2560-FQ" were not winning crowns, and that respondents were not negligent in conducting the promotion.

• Res Judicata Inapplicable: Petitioners maintained that res judicata does not apply because there is no identity of parties between the present case and the Mendoza and Rodrigo cases.
• Stare Decisis Not Absolute: Petitioners argued that stare decisis is not a hard and fast rule and that another review of the cause of action should be undertaken because the Court of Appeals erred in the Mendoza and Rodrigo cases in ruling that the security code determines the real winning crowns.
• Premature Dismissal: Petitioners contended that the trial court's dismissal of their complaint was premature, given that the motion to archive was granted on the condition that there be a final resolution in the Mendoza and Rodrigo cases.
• Breach of Contract: Petitioners posited that a contract was breached between the parties and that respondents should therefore be made to perform their contractual obligation.

• Res Judicata / Stare Decisis: Respondents countered that the RTC correctly dismissed petitioners' complaint on the ground of res judicata, as the civil cases filed by petitioners arose from the same "Number Fever" promotion and involved the same causes of action and testimonial and documentary evidence as the Mendoza and Rodrigo cases.
• Identical Findings of Fact: Respondents pointed out that the findings of fact in the Mendoza and Rodrigo cases were the same—namely, that respondents did not breach any contract since the "349" crowns with security code "L-2560-FQ" are not winning crowns, and that respondents were not negligent in the conduct of their promotion and exerted efforts to ensure its integrity and smooth conduct.

• Stare Decisis: Whether the present case is barred by this Court's final rulings in the Mendoza and Rodrigo cases under the doctrine of stare decisis.

• Stare Decisis: Yes. The petition is barred by stare decisis. The legal rights and relations of the parties, the facts, applicable laws, causes of action, issues, and evidence are exactly the same as those in the Mendoza and Rodrigo cases, which have become final. The Court's hands are tied by the finality of those judgments.

• Stare Decisis: The doctrine of stare decisis et non quieta movere—"to adhere to precedents and not to unsettle things which are established"—is entrenched in Article 8 of the Civil Code, which provides that judicial decisions applying or interpreting the laws or the Constitution shall form part of the legal system of the Philippines. The doctrine enjoins adherence to judicial precedents and requires courts to follow a rule already established in a final decision of the Supreme Court, which becomes a judicial precedent binding on all courts in subsequent cases. It is founded on the principle that once a question of law has been examined and decided, it should be deemed settled and closed to further argument. In the instant case, the legal rights and relations of the parties, the facts, the applicable laws, the causes of action, the issues, and the evidence are exactly the same as those in the decided cases of Mendoza and Rodrigo. Nothing is left to be argued; the issue has been settled, and the finality of those judgments must be respected. The Court has no recourse but to deny the petition.

• Stare Decisis et Non Quieta Movere — The doctrine of adhering to precedents and not unsettling things which are established. Under Article 8 of the Civil Code, judicial decisions applying or interpreting the laws or the Constitution form part of the legal system of the Philippines. The doctrine requires courts to follow a rule already established in a final decision of the Supreme Court, which becomes a binding judicial precedent in subsequent cases. It is based on the principle that once a question of law has been examined and decided, it should be deemed settled and closed to further argument. The doctrine does not require identity or privy of parties; it applies where the legal rights and relations, facts, applicable laws, causes of action, issues, and evidence are substantially or exactly the same as those in a previously decided case. In this case, the Court applied the doctrine to bar relitigation of the "Number Fever" controversy because the Mendoza and Rodrigo cases had already resolved the identical issues with finality.

• "The doctrine of stare decisis is based on the principle that once a question of law has been examined and decided, it should be deemed settled and closed to further argument." — This passage articulates the foundational rationale of stare decisis as applied in Philippine jurisprudence, explaining why courts are bound by prior final rulings on identical legal questions.
• "In the instant case, the legal rights and relations of the parties, the facts, the applicable laws, the causes of action, the issues, and the evidence are exactly the same as those in the decided cases of Mendoza and Rodrigo, supra. Hence, nothing is left to be argued." — This is the ratio decidendi: the Court's application of the identity test to conclude that stare decisis bars the petition.
• "This Court's hands are now tied by the finality of the said judgments. We have no recourse but to deny the instant petition." — This passage underscores the binding effect of final judgments on subsequent cases involving identical issues, illustrating the practical compulsion of stare decisis.

• Mendoza vs. Pepsi-Cola Products Philippines, Inc., G.R. No. 153183 (July 24, 2002) — Controlling precedent. The Supreme Court denied the petition for review, affirming the Court of Appeals' dismissal of Mendoza's appeal. The case arose from the same "Number Fever" promotion and established the ruling that the "349" crowns with security code "L-2560-FQ" are not winning crowns and that respondents were not negligent.
• Rodrigo vs. Pepsi Cola Products (Phils.), Inc. and Pepsico, Inc., G.R. No. 149411 (October 1, 2001) — Controlling precedent. The Supreme Court denied the petition for review and motion for reconsideration with finality; entry of judgment was made on February 5, 2002. The case involved identical facts, causes of action, issues, and evidence, and its final ruling was the primary basis for the RTC's dismissal of petitioners' complaints under stare decisis.
• Castillo vs. Sandiganbayan, G.R. No. 138231 (February 21, 2002) — Cited as authority for the definition and application of the doctrine of stare decisis.
• Kilosbayan, Inc. vs. Manuel Morato, G.R. No. 118910 (July 17, 1995) — Cited by the RTC for the proposition that judicial decisions assume the same authority as the statute itself and become criteria controlling the actuations of those bound to enforce obedience thereto.

• Article 8, Civil Code of the Philippines — 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 as the statutory basis for the doctrine of stare decisis, holding that final Supreme Court decisions on identical facts and issues are binding precedents that must be followed in subsequent cases.
