G.R. No. 153063-70 - De Mesa vs. Pepsi Cola Products Philippines, Inc.

Case Summary (G.R. No. 153063-70)

Applicable Law and Constitutional Basis

The decision applies the 1987 Philippine Constitution as the governing constitutional framework (case decision date post‑1990). The Civil Code (Article 8) is specifically relied upon: “Judicial decisions applying or interpreting the laws or the Constitution shall form a part of the legal system of the Philippines,” which underpins the doctrine of stare decisis and the obligation of lower courts to follow settled Supreme Court rulings.

Promotional Mechanics and Security Safeguards

During the initial promotion (February 17 to May 8, 1992), respondents “seeded” 1,000 bottle‑cap numbers: 60 designated winning numbers, 510 non‑winning numbers, and 430 unused numbers. D.G. Consultores randomly preselected winning numbers and associated security codes; respondents submitted the winning numbers and security codes to the DTI and deposited them in a bank safety deposit box as required to prevent tampering and to ensure integrity.

Extension of Promotion, Announcement of “349,” and Alleged Error

Because of the campaign’s success, respondents extended the promotion for five weeks (May 10 to June 12, 1992). D.G. Consultores selected 25 additional winning numbers from unused numbers for the extension. On May 25, 1992, respondents publicly announced “349” as the winning number for the May 26 draw. Later that night, PCPPI’s Marketing Services Manager informed DTI Director Madarang that a security‑code problem had caused a mistake in announcing “349” as a winning number.

Filing of Actions by Crown Holders

Numerous holders of caps bearing “349” who were not paid by respondents filed separate complaints for specific performance and damages. Several actions proceeded in different trial courts: one matter (initially Civil Case No. 93‑68351) resulted in a single plaintiff (Gerson Mendoza) pursuing relief; others were filed as Romulo Rodrigo et al. (Civil Case No. 94‑71403). Petitioners in the present proceedings filed separate suits numbered Civil Cases Nos. 94‑2414 to 94‑2421 before the Regional Trial Court (RTC) of Makati, Branch 142.

Parallel Litigation and Finality of Mendoza and Rodrigo Decisions

In Mendoza’s case, the RTC dismissed the complaint; the Court of Appeals affirmed; this Court denied Mendoza’s petition for review. In Rodrigo’s case, the RTC dismissed the complaint; the Court of Appeals affirmed; this Court denied the petition for review and denied reconsideration, rendering the appellate rulings final and executory. These earlier cases determined, among other things, that the security code — not the announced crown number alone — determines which crowns were winning and that respondents did not breach contract or act negligently in conducting the promotion.

Petitioners’ Motion to Archive and Subsequent Procedural Posture

On December 11, 2000, petitioners moved in the RTC for leave either to adopt testimonial and documentary evidence from Mendoza and Rodrigo or to archive their cases pending final resolution of those appeals; the RTC granted the motion on January 8, 2001 and archived the cases. After Rodrigo became final and executory (February 5, 2002), respondents filed a motion to dismiss the archived cases on February 20, 2002, invoking the doctrine of stare decisis (res judicata/preclusive effect of the final rulings). The RTC granted the motion to dismiss by Order dated April 18, 2002.

Issues Presented by Petitioners and Respondents’ Position

Petitioners’ contentions on review were: (1) res judicata does not apply because of lack of identity of parties; (2) stare decisis is not absolute and the subject issues merit fresh review because the appellate rulings erred in treating security codes as determinative of winning crowns; (3) dismissal was premature because the archive was conditional on final resolution of Mendoza and Rodrigo; and (4) respondents breached contractual obligations. Respondents maintained that res judicata and stare decisis barred relitigation because the present cases derive from the same promotion, involve identical causes of action, issues, testimonial and documentary evidence, and rely on the same factual findings that respondents did not breach contract and were not negligent.

Court’s Legal Analysis: Stare Decisis and Identity of Matters

The Court centered its analysis on Article 8 of the Civil Code and the doctrine of stare decisis et non quieta movere. It emphasized that judicial decisions applying or interpreting the law become part of the legal system and, when final, establish rules of law to be followed by courts in subsequent, similar matters. The Court found

Case Syllabus (G.R. No. 153063-70)

Procedural Posture

Petition for review on certiorari filed with the Supreme Court to challenge the Order dated April 18, 2002 of the Regional Trial Court (RTC) of Makati City, Branch 142 in Civil Cases Nos. 94-2414 to 94-2421.
The RTC had granted respondents’ motion to dismiss petitioners’ complaints based on the principle of stare decisis.
The case arises from the same set of facts as Mendoza v. Pepsi-Cola Products Philippines, Inc., et al., G.R. No. 153183 (promulgated July 24, 2002), and Rodrigo v. Pepsi Cola Products (Phils.), Inc. and Pepsico, Inc., G.R. No. 149411 (dated October 1, 2001), which had affirmed Court of Appeals decisions (CA-G.R. CV No. 53860 and CA-G.R. CV No. 62837, respectively).
The Supreme Court, in the present petition, ultimately DENIED the petition and AFFIRMED the RTC Order dismissing the complaints. Costs were taxed against petitioners.

Parties

Petitioners: Amelia D. De Mesa, Araceli Adato, Rodrigo Alvaran, Aida Castro, Baltazar Estrelles, Antonio A. Ferrer, Danilo Garcia, Julio M. Gonzales, Marrieta A. Jose, Pepita Juntado, Eduardo U. Lago, Nestor Roda, Jaime Sanchez, and Juanita Sanchez — holders of soft drink bottle caps bearing the number "349," allegedly winning in respondents’ promotion.
Respondents: Pepsi Cola Products Phils., Inc. (PCPPI), a domestic corporation engaged in 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.
Third party/contracted firm involved in promotion mechanics: D.G. Consultores, a Mexican consulting firm tasked to randomly pre-select winning numbers and provide a list of winning numbers and corresponding security codes to respondents.
Government/regulatory involvement: Department of Trade and Industry (DTI) — approved the process of selecting winning numbers and required respondents to deposit the list of winning numbers with security codes in a bank safety deposit box.

Facts (Promotion Mechanics and Security Measures)

The promotion at issue is the "Number Fever" contest sponsored by respondents.
D.G. Consultores randomly pre-selected winning numbers and sent respondents a list of 60 winning numbers with corresponding security codes.
The DTI required respondents to submit the list of winning numbers, including their security codes, which the DTI then deposited in a bank safety deposit box to secure the numbers from tampering.
During the initial promotion period (February 17 to May 8, 1992), respondents seeded 1,000 numbers as follows: 60 winning numbers, 510 non-winning numbers, and 430 unused numbers.
Because of promotional success, the "Number Fever" promotion was extended five weeks (May 10 to June 12, 1992).
Pepsi again engaged D.G. Consultores to predetermine 25 additional winning numbers from the list of previously unused numbers.
On May 25, 1992, respondents announced "349" as the winning number for the May 26 draw.
Later that same night, Quintin Gomez, Jr., PCPPI’s Marketing Services Manager, called DTI Director Madarang to inform her that due to some security code problems a mistake had been made in the announcement of number "349" as the winning number.
Numerous holders of crowns bearing "349" were not honored or paid by respondents, leading rejected crown holders to file separate complaints for specific performance and damages.

Parallel and Related Litigation (Mendoza and Rodrigo Cases)

Civil Case No. 93-68351 (Mendoza case) was originally filed before the RTC of Manila, Branch 16; plaintiffs withdrew, leaving Gerson Mendoza as sole plaintiff in Gerson M. Mendoza v. Pepsi-Cola Products Phils., Inc. and Pepsico, Inc.
Other plaintiffs re-filed complaints before the RTC of Manila, Branch 50, titled Romulo Rodrigo, et al. v. Pepsi Cola Products Philippines, Inc., et al., docketed as Civil Case No. 94-71403 (Rodrigo case).
In the Mendoza case, the RTC dismissed the complaint for specific performance and damages; the Court of Appeals dismissed Mendoza’s appeal for lack of merit; the Supreme Court denied Mendoza’s petition for review for failure to show reversible error (G.R. No. 153183, promulgated July 24, 2002).
In the Rodrigo case, the RTC likewise dismissed the complaint; the Court of Appeals affirmed the RTC decision (CA-G.R. CV No. 62837); the Supreme Court denied the subsequent petition for review and motion for reconsideration, rendering the judgment final and executory.

Petitioners’ Proceedings in Makati (Civil Cases Nos. 94-2414 to 94-2421)

Petitioners filed separate complaints in the RTC Makati, Branch 142, docketed as Civil Cases Nos. 94-2414 to 94-2421.
On December 11, 2000, petitioners filed a motion for leave to either (1) adopt testimonial and documentary evidence previously presented in the Mendoza and Rodrigo cases, or (2) archive the cases until final resolution of those two then-pending Court of Appeals cases.
The RTC granted the motion to archive on January 8, 2001, and the Makati cases were archived pending final resolution of Mendoza and Rodrigo.
