GSIS vs. Court of Appeals

A final and executory judgment is immutable and unalterable; its execution is a ministerial duty. A conflicting judgment from a co-equal court, rendered after the first judgment attained finality, does not constitute a "supervening event" that would justify staying execution.

LLDHC owned the subject lots. After LLDHC defaulted on a loan, GSIS foreclosed the mortgage and consolidated ownership. GSIS later sold the lots to GMC via a Deed of Conditional Sale. LLDHC filed a case (Manila RTC) to annul the foreclosure, while GMC filed a case (Lapu-Lapu RTC) for specific performance to compel GSIS to execute a final deed of sale.

• Lapu-Lapu RTC (Civil Case No. 2203-L): Ruled in favor of GMC (Feb. 24, 1992). GSIS's and LLDHC's appeals were dismissed. The decision became final and executory.
• Manila RTC (Civil Case No. R-82-3429): Ruled in favor of LLDHC, annulling the foreclosure (May 10, 1994). This decision also became final and executory.
• Multiple CA & SC Petitions: LLDHC and GSIS filed several petitions (e.g., for annulment of judgment, certiorari) seeking to nullify the Lapu-Lapu RTC decision, all of which were dismissed with finality.
• Execution Attempts: The Lapu-Lapu RTC issued orders for execution, but implementation was delayed by the Manila RTC's execution of its own judgment and further petitions.
• CA Decisions: The CA's 20th Division affirmed the Lapu-Lapu RTC's 2004 execution orders (CA-G.R. SP No. 85096). The CA's 19th Division annulled those same orders (CA-G.R. SP No. 84382), creating a conflict.
• Elevation to SC: GSIS (G.R. No. 167000) and GMC (G.R. No. 169971) filed petitions for review on certiorari, which were consolidated.

• LLDHC was the original owner of 78 lots in Lapu-Lapu City.
• GSIS foreclosed on LLDHC's mortgage and acquired the lots.
• GSIS sold the lots to GMC via a conditional sale. GMC fully paid the purchase price.
• LLDHC sued GSIS in Manila RTC to annul the foreclosure (Civil Case No. R-82-3429).
• GMC sued GSIS in Lapu-Lapu RTC for specific performance (Civil Case No. 2203-L).
• The Lapu-Lapu RTC ruled for GMC (1992). The Manila RTC ruled for LLDHC (1994).
• Both judgments became final and executory. The Manila RTC judgment was executed first, transferring titles to LLDHC.
• The Lapu-Lapu RTC subsequently issued orders (2004) to execute its original 1992 judgment, directing the Sheriff and Register of Deeds to transfer titles to GMC.

GSIS (G.R. No. 167000): - The Manila RTC judgment and the transfer of titles to LLDHC are supervening events that make execution of the Lapu-Lapu RTC judgment legally and physically impossible. - GSIS funds are exempt from execution under its charter (R.A. No. 8291, Sec. 39).

LLDHC (via its arguments in CA-G.R. SP No. 84382, challenged by GMC in G.R. No. 169971): - The Manila RTC judgment nullified the Lapu-Lapu RTC judgment. - Execution of the Lapu-Lapu RTC judgment should be stayed due to the supervening event.

GMC (Opposing GSIS and LLDHC): - The Lapu-Lapu RTC judgment is valid, final, and has been upheld by the CA and SC in prior rulings. - The petitions are barred by res judicata. - LLDHC and GSIS are guilty of forum shopping. - The Manila RTC judgment is not binding on GMC as it was not a party to that case. - GSIS's claim of exemption is not absolute and does not apply to its contractual obligations.

• Procedural Issues: Whether the petitions (G.R. No. 167000 and CA-G.R. SP No. 84382) are barred by res judicata. Whether LLDHC and GSIS are guilty of forum shopping.
• Substantive Issues:
  1. Whether the Manila RTC decision constitutes a supervening event that justifies staying the execution of the final Lapu-Lapu RTC decision.
  2. Whether it is legally and physically impossible for GSIS to comply with the Lapu-Lapu RTC's execution orders.
  3. Whether GSIS funds are exempt from the monetary judgment.

• Procedural:
  • Res Judicata: The SC found the petitions barred. The core issue—the validity and enforceability of the Lapu-Lapu RTC judgment—had been finally resolved in prior SC and CA decisions (e.g., G.R. No. 141407). The elements of res judicata (final judgment on the merits, by a court of jurisdiction, identity of parties/subject matter/cause of action) were present.
  • Forum Shopping: The SC reiterated its 2002 finding that LLDHC was guilty of forum shopping for repeatedly filing petitions to annul the same judgment. GSIS was also found guilty for raising the same grounds in a new petition.
• Substantive:
  1. Supervening Event: The Manila RTC decision was not a supervening event. It was promulgated before the Lapu-Lapu RTC decision attained finality. A supervening event must occur after a judgment becomes final. The SC gave precedence to the Lapu-Lapu RTC judgment because it was rendered and became final earlier than the Manila RTC judgment.
  2. Impossibility of Compliance: The argument was baseless. The Lapu-Lapu RTC's later execution orders were directed at the Register of Deeds and the Sheriff, not GSIS. GSIS had no active duty to perform.
  3. GSIS Exemption: The exemption under Sec. 39 of R.A. 8291 is not absolute. It does not cover funds and properties used in GSIS's business ventures and contractual obligations. GSIS cannot hide behind sovereign immunity for liabilities arising from its proprietary functions.

• Doctrine of Finality of Judgment / Immutability of Judgments — A final judgment is unalterable and may not be modified, even if erroneous. Exceptions are narrow (e.g., clerical errors, void judgments, supervening events making execution unjust). The SC applied this strictly, refusing to alter the Lapu-Lapu RTC's final decision.
• Supervening Event Doctrine — An exception to immutability. An event must (1) transpire after the judgment becomes final and executory, and (2) render execution unjust or impossible. The SC found the Manila RTC decision failed the first prong.
• Res Judicata (Bar by Prior Judgment & Conclusiveness of Judgment) — A final judgment on the merits bars a subsequent action between the same parties on the same claim (bar) or conclusively determines issues actually litigated (conclusiveness). The SC applied both concepts to dismiss the repetitive petitions.
• Forum Shopping — The filing of multiple suits involving the same parties and issues in different courts to increase chances of a favorable verdict. The SC condemned the practice as an abuse of court processes.
• Doctrine of Co-Equal Courts — Courts of co-equal and coordinate jurisdiction cannot interfere with each other's orders or processes. The Manila RTC could not nullify the Lapu-Lapu RTC's final judgment.

• "The doctrine of finality of judgment is grounded on fundamental considerations of public policy and sound practice, and that, at the risk of occasional errors, the judgments or orders of courts must become final at some definite time fixed by law; otherwise, there would be no end to litigations."
• "A final judgment vests in the prevailing party a right recognized and protected by law under the due process clause of the Constitution."
• "The insidious practice of repeatedly bringing essentially the same action — albeit disguised in various nomenclatures — before different courts at different times is forum shopping no less."
• "The exemption [of GSIS funds] should be limited to the purposes and objects covered. Any interpretation that would give it an expansive construction to exempt all GSIS assets from legal processes absolutely would be unwarranted."

• Lapulapu Development and Housing Corporation v. Group Management Corporation (G.R. No. 141407, 2002) — Controlling precedent where the SC previously upheld the finality of the Lapu-Lapu RTC decision, rejected the Manila RTC decision as a ground for annulment, and found LLDHC guilty of forum shopping.
• Rubia v. Government Service Insurance System (2004) — Established that the GSIS exemption from execution under its charter is not absolute and does not cover its proprietary/contractual obligations.
• Government Service Insurance System v. RTC of Pasig City, Branch 71 (2009) — Reiterated the Rubia ruling that GSIS cannot claim absolute immunity for liabilities arising from its business transactions.
• Republic v. Yu (2006) — Cited for the definition and elements of res judicata.
• Villanueva v. Court of Appeals (1998) — Cited for the elements of res judicata and the policy against relitigation.
• Collantes v. Court of Appeals (2007) — Cited for the options in resolving conflicting final judgments (re-litigate, prioritize earlier finality, or prioritize higher court's judgment).

• Rule 39, Sec. 47(b) & (c) of the 1997 Rules of Civil Procedure — Governs the effects of final judgments, embodying the doctrines of bar by prior judgment and conclusiveness of judgment.
• Sec. 39, Republic Act No. 8291 (GSIS Act of 1997) — Provides for the exemption of GSIS funds from tax, legal process, and lien. The SC interpreted this provision narrowly.
• Batas Pambansa Blg. 129, Sec. 9(2) — Cited to establish the CA's original jurisdiction over annulment of RTC judgments, relevant to the procedural history.
