G.R. No. 169202 - Remo vs. Secretary of Foreign Affairs

On September 10, 1981, private respondents, spouses Manuel and Leticia De Guia, filed Civil Case No. PQ-9412-P before the Court of First Instance of Rizal in Pasay City seeking specific performance and damages, particularly the execution of a deed of sale for two parcels of land according to a contracted sale with spouses Jovito and Norma Valenzuela.
On September 16, 1981, upon learning that the subject properties had been sold to other parties, the De Guías filed Civil Case No. PQ-9432-P praying for annulment of the sale, cancellation of titles, and, alternatively, reconveyance of the properties back to the Valenzuelas.

On October 13, 1981, the complaint in Civil Case No. PQ-9432-P was amended to implead Webb-Hegg Construction Resources, Inc. as an additional defendant.
On January 19, 1983, a motion to admit a second amended complaint was filed in the same case to add Gerardo Villacorta as a defendant.
Following the transfer of Civil Case No. PQ-9432-P to the Regional Trial Court (RTC) of Makati (redocketed as Civil Case No. 2723), the RTC of Makati admitted the second amended complaint on May 20, 1983.
Private respondents subsequently filed a motion to admit a third amended complaint in RTC-Pasay, which sought to implead additional parties (spouses De Guzman, De Guzman Development Corporation, Skyfreight Brokerage, Inc., and Lawyer Romeo Bobadilla), but on May 30, 1984, RTC-Pasay denied that motion and vacated the earlier admission by RTC-Makati.

After unsuccessful motions for reconsideration and an eventual petition for certiorari and prohibition before the Court of Appeals (CA), the CA rendered on August 15, 1997, a decision setting aside the RTC orders that had denied the amendment, thereby ordering the admission of the amended complaint dated March 18, 1997.
On November 5, 1997, RTC-Pasay, Branch 231, complied by admitting the amended complaint pursuant to the CA decision.
A manifestation with a motion to reconsider was filed by petitioners with the lower court, accompanied by an indication of intent to file a petition for review on certiorari before the Supreme Court. Private respondents opposed this move, and later, the RTC ordered the admission and service of summons to be held in abeyance pending the Supreme Court’s resolution.

On December 17, 1997, petitioners filed the instant petition before the Supreme Court, contesting the propriety of the amendment of the complaint.
Petitioners argued that the introduction of amendments would “radically and substantially change the cause of action and theory” of the case after a lengthy delay spanning nearly two decades.
The controversy arose in the context of multiple procedural incidents, including the dismissal of Civil Case No. PQ-9432-P on the ground of litis pendentia, reflecting the prolonged dispute and procedural complexities between the parties.

The case involved a detailed review of Section 1, Rule 10 and Section 3, Rule 10 of the 1997 Rules of Civil Procedure, which govern the amendment of pleadings.
The Rules stress that amendments are allowed “without regard to technicalities” so as to secure a “just, speedy and inexpensive disposition” of cases—even if the amendment may substantially alter the cause of action or defense.
Related jurisprudence and doctrines, such as the non-vested nature of procedural rights and the retroactive application of procedurally oriented statutes, were also pivotal in the case’s factual matrix.

Whether the motion to amend the complaint filed after a lapse of fifteen years from the original filing should be granted or denied.
Whether allowing the amendment would substantially alter the cause of action or defense to an extent that would be prejudicial to the parties.
Whether the application of the 1997 Rules of Civil Procedure—with their allowance for amendments irrespective of technicalities—overrides any arguments based on the elapsed time or change in the substance of the pleadings.
Whether the doctrine of res judicata, particularly through the lens of conclusiveness of judgment, bars the examination or admission of the amended complaint given that the related case (Civil Case No. PQ-9432-P) was dismissed on the ground of litis pendentia.
