Judicial Approval Makes Compromise Agreements Final and Executory

A compromise agreement is a contract where parties make reciprocal concessions to end a lawsuit. Once a court approves it, the agreement stops being an ordinary contract. It becomes a judgment of the court — final, executory, and binding on the parties. In Tung Hui Chung v. Shih Chiu Huang (G.R. No. 170679, March 9, 2016), the Supreme Court clarified the limits of attacking such a judgment, ruling that a party cannot use certiorari to undo a judicially approved compromise on grounds of fraud.

The Case Before the Court

The petitioners, Australian citizens, sued the respondent to recover money and damages arising from a contract to sell shares of stock worth P10,606,266.00. The case was filed in the Regional Trial Court (RTC), Branch 49, Manila, as Civil Case No. 01-101260. The RTC later granted a writ of preliminary attachment against the respondent's properties.

On August 19, 2003, the parties executed a compromise agreement. The respondent acknowledged an obligation of US$250,000.00, payable in installments from 2003 to 2007. The RTC approved the agreement on October 20, 2003. The respondent paid the first installment of US$20,000.00, and the parties jointly moved to partially lift the attachment.

When the respondent failed to pay the second installment due on November 15, 2004, the petitioners moved for execution. The RTC granted the motion and issued a writ of execution. The respondent then filed a petition for certiorari with the Court of Appeals (CA), which annulled the compromise agreement on the ground of fraud and lack of valid consent. The CA found it "incredible" that the respondent became liable for US$250,000.00 when the amended complaint prayed for only P10,606,266.00.

The Issue

The Supreme Court addressed whether the CA correctly nullified the judicially approved compromise agreement on the ground of fraud and vitiated consent.

The Ruling: A Judicially Approved Compromise Is a Final Judgment

The Supreme Court granted the petition and reinstated the RTC judgment based on the compromise agreement. The Court held that the CA acted without jurisdiction in annulling the agreement.

Once a compromise agreement is stamped with judicial approval, it ceases to be a mere contract. It becomes a judgment of the court, enforceable through a writ of execution. Under Article 2037 of the Civil Code, a compromise has the effect and authority of res judicata between the parties. It is immediately final and executory unless rescinded upon grounds that vitiate consent.

The Court emphasized that a final judgment is immutable and unalterable. This doctrine rests on public policy: every litigation must come to an end at some definite time. A judgment based on a compromise cannot be assailed through certiorari, especially when filed beyond the 60-day period under Section 4, Rule 65 of the Rules of Court.

The Proper Remedy: Annulment Under Rule 47

If a party wishes to attack a judgment based on a compromise on the ground of extrinsic fraud, the remedy is an original action for annulment of judgment under Rule 47 of the Rules of Court. Under Section 2 of Rule 47, such an action may be based only on extrinsic fraud or lack of jurisdiction.

The Court cited Dare Adventure Farm Corporation v. Court of Appeals (G.R. No. 161122, September 24, 2012) to emphasize that annulment of judgment is an exceptional remedy. It is available only when ordinary remedies — new trial, appeal, petition for relief — are no longer available through no fault of the petitioner. The remedy cannot be abused by parties aggrieved by final judgments.

In this case, the respondent could have availed of a petition for relief from judgment under Rule 38. His failure to do so precluded him from seeking annulment under Rule 47.

Practical Takeaways

• A compromise agreement approved by the court is immediately final and executory. It has the force of res judicata and can be enforced by writ of execution.
• Judicial approval transforms the agreement. It is no longer just a contract between the parties but a judgment of the court, subject to the doctrine of immutability.
• Certiorari is not the proper remedy to attack a judgment based on a compromise on grounds of fraud or lack of consent. Such grounds are not jurisdictional errors.
• Annulment of judgment under Rule 47 is the limited remedy for extrinsic fraud or lack of jurisdiction, and only if ordinary remedies are no longer available through no fault of the petitioner.
• Timing matters. Petitions for certiorari must be filed within 60 days from notice. Annulment based on extrinsic fraud must be filed within four years from discovery.
