G.R. No. 192935 - Biraogo vs. Philippine Truth Commission of 2010

On June 25, 1982, Filinvest Credit Corporation filed Civil Case No. 46556 in the defunct Court of First Instance of Rizal, Branch XXIV, against petitioner’s spouse, Abel (alias Abelardo) Sahagun, manager of Rallye Motor Co., Inc.
The suit alleged that Abel Sahagun made it appear that his company had sold a motor vehicle to Ernesto Salazar, who issued a promissory note secured by a chattel mortgage on the said vehicle in favor of Rallye.
The promissory note and chattel mortgage were subsequently assigned to Filinvest for valuable consideration.

It was later discovered by Filinvest that the mortgaged car had not been delivered to Salazar as purportedly indicated by Abel Sahagun.
The non-delivery claim was central to Filinvest’s allegation of fraud, as the underlying security interest became defective upon non-performance.

A writ of attachment was executed on a house and lot registered in Abel Sahagun’s name, located at No. 16 Mangga Chupoy St., Pilar Village Subdivision, Las Piñas, Metro Manila.
Petitioner Carmelita Sahagun, who claimed continuous residence and personal financial contribution in acquiring the property, maintained that the house was her own.
Carmelita later intervened in the suit and questioned the jurisdiction of the trial court, thereby complicating the procedural posture.

On June 2, 1983, the trial court ordered that steps be taken to effect service of summons and complaint on defendant Abel Sahagun, who was then abroad with his whereabouts in the United States unknown.
Due to failure to effect extraterritorial service in compliance with the order, the trial court dismissed Filinvest’s complaint without prejudice on June 23, 1983.
Filinvest filed a motion for reconsideration seeking to declare Abel Sahagun in default; however, the trial court on July 7, 1983, granted petitioner time to file a complaint in intervention while denying Filinvest’s motion.
Petitioner Carmelita Sahagun, after intervening on July 27, 1983, was later declared in default for failure to appear at the pre-trial conference, and Abel Sahagun was similarly declared in default for not answering the complaint.

On February 20, 1984, the court rendered judgment against Abel Sahagun ordering him to pay sums including principal, interest, liquidated damages, and attorney’s fees.
Petitioner’s elevation of the case to the Intermediate Appellate Court resulted in her obtaining certiorari with prohibition that set aside the trial court’s decision and order for execution.
Filinvest subsequently sought review from the Court of Appeals, which dismissed the petition for review and later denied a motion for reconsideration.
A subsequent effort by Filinvest for extraterritorial service of summons on Abel Sahagun through publication generated further controversy due to inconsistent addresses and defective compliance with the registered mail requirement.

Whether the trial court had acquired jurisdiction over the nonresident defendant, Abel Sahagun, by effecting service of summons through publication in a newspaper of general circulation in the Philippines.
Whether publication in a Philippine newspaper sufficiently complied with Section 17, Rule 14, despite the defendant's residence in the United States.

Whether the failure to send copies of the summons and amended complaint by registered mail to the defendant’s last known correct address constitutes a fatal defect in compliance.
How the inconsistency between the addresses used for service (No. 16 Mangga Chupoy St. versus No. 1228-A Antipolo Street) affects the validity of the service.

Whether the purported flaws in the service process denied the absent defendant the opportunity to be heard, thereby contravening due process requirements.
The extent to which the erroneous service method impacts the court’s jurisdiction over the defendant’s person versus its jurisdiction over the property (quasi in rem).
