G.R. No. 120744-46 - Yapyuco y Enriquez vs. Sandiganbayan

Case Summary (G.R. No. 120744-46)

Factual Background

On the evening of April 5, 1988, employees leaving a barrio fiesta in Barangay Quebiawan, San Fernando, Pampanga, boarded a green Toyota Tamaraw jeepney driven by Noel C. Villanueva with Leodevince S. Licup as front passenger and several companions at the rear. As the vehicle negotiated a curve between about 5:00 and 7:30 p.m., occupants heard a sudden burst of gunfire. Villanueva and Licup were struck and bled profusely; Licup later died at Makati Medical Center on April 7, 1988. Eyewitnesses Eduardo S. Flores and Salangsang described a volley of shots from the right side of the road near the residence of a certain Lenlen Naron, the rapid transfer of the wounded into another jeepney which departed with two armed men seated beside the driver, and the discovery of multiple bullet holes concentrated on the passenger side of the Tamaraw.

Accusations and Informations

The accused were charged in three Informations as participants in a coordinated attack: Criminal Case No. 16612 charged murder for the death of Licup; Criminal Case No. 16613 charged multiple attempted murder against other occupants; and Criminal Case No. 16614 charged frustrated murder as to Villanueva. The accused included police officers stationed at the Sindalan Substation—Salvador Yapyuco, Generoso Cunanan, Jr., and Ernesto Puno—barangay captains Jose Pamintuan and Mario Reyes, and several members of the Civil Home Defense Force or civilian volunteer officers including Andres Reyes, Virgilio Manguerra, and others. Most accused surrendered and entered pleas of not guilty; certain accused later died or had charges dismissed.

Prosecution Evidence

The prosecution presented eyewitness testimony from Flores, Villanueva, and Salangsang, a sketch showing the relative positions of the Tamaraw and the assailants, and expert reports. Forensic chemist Dolly Dabor testified to the presence of gunpowder residue on firearms issued to some accused and to eleven bullet holes on the Tamaraw, principally on the passenger side, with punctures at oblique and perpendicular angles. Medico-legal consultant Dr. Pedro Solis, Jr. described wounds on Villanueva and Licup and opined on likely trajectories and possible positions of assailants and victims. Administrative records showed issuance of service firearms to certain accused. The prosecution relied substantially on the testimony and physical evidence to infer discharge of weapons by the accused and to reconstruct lines of fire.

Defense Evidence and Contentions

The defense, primarily through the testimony of Yapyuco, maintained that the police and allied civilian forces responded to a summons reporting armed NPA elements in the barangay. Yapyuco testified that he and his men took positions to flag down the suspect vehicle, fired warning shots when it allegedly failed to stop, and then fired at the tires when the vehicle accelerated to flee; he denied an ambuscade and denied firing directly at occupants with intent to kill. Other accused maintained they fired only warning shots or that gunfire later emanated from CHDF members in a yard. Petitioners invoked the justifying circumstance of lawful performance of duty under Article 11(5) and the defense of mistake of fact, argued that evidence did not establish conspiracy, and contested admission and attribution of certain evidence.

Trial Court Findings and Sentence

The Sandiganbayan found that the accused acted under a guise of law enforcement but willfully and collectively discharged firearms with common purpose, thereby causing Licup’s death and Villanueva’s injuries. It concluded that conspiracy and collective responsibility were proven by the concentration and trajectories of bullet entries, the strategic placement of the accused, the deliberate darkening of nearby lights, and ballistics showing firearm discharge. Treachery and evident premeditation were not proven. The Sandiganbayan converted the murder charge to homicide for Licup and convicted several accused as co-principals; it likewise found attempted homicide as to Villanueva and acquitted others of multiple attempted murder. It imposed indeterminate penalties, ordered indemnity and moral/exemplary damages, and credited voluntary surrender as mitigating circumstance.

Issues on Review

On certiorari, petitioners challenged the Sandiganbayan’s findings of conspiracy and collective responsibility, the sufficiency and admissibility of evidence attributed to them, and the rejection of their defense of lawful performance of duty and mistake of fact. They urged that the prosecution failed to identify the individual shooters and that, at most, reckless imprudence would apply. Some petitioners also alleged denial of due process because evidence adduced in separate proceedings or at pretrial stages was used against them in joint disposition.

Supreme Court Analysis on Evidence and Admissions

The Supreme Court reviewed the record and emphasized that the prosecution must identify the criminal actor as well as prove corpus delicti beyond reasonable doubt. It observed that petitioners were present at the scene and that several signed extrajudicial affidavits and counter-affidavits described firing at the fleeing vehicle. The Court held that when an accused repeats an extrajudicial admission in open court and is subject to cross-examination, the admission becomes a judicial admission and becomes binding on co-accused who elected not to contradict it. The Court rejected due process claims tied to the reproduction of evidentiary materials because petitioners had agreed to joint trial procedures and had waived presentation of further evidence.

Application of Justification and Mistake of Fact Doctrines

The Court outlined the requisites of Article 11(5) of the Revised Penal Code: that the accused acted in performance of duty and that the injury was a necessary consequence of due performance. It held that petitioners bore the burden to prove necessity and lack of negligence. The Court found the requisites unmet because the record showed no reasonable basis to use lethal force immediately, alternatives such as pursuit existed, and there was no evidence the victims posed an imminent mortal threat. Citing People v. Ulep, People v. Tabag, and other authorities, the Court reiterated that police may use force only as reasonably necessary and as last resort. On mistake of fact, the Court recited the governing standard from United States v. Ah Chong and related Philippine cases: mistake of fact must be honest, reasonable, and not caused by negligence. The Court found petitioners’ asserted belief that the occupants were armed was not a reasonable basis for immediately firing upon a moving passenger vehicle and that negligence or imprudence attended their conduct.

Conspiracy, Intent and Criminal Agency

The Court reasoned that conspiracy may be inferred from conduct before, during and after the offense and that it need not rest on a prolonged prior agreement. It found that petitioners shared a common purpose to prevent purported escape and that their concerted and nearly simultaneous firing from strategically chosen posts produced bullet patterns consistent with coordinated action. Given the weapons employed, the concentration of bullet holes on the passenger side, and the medical evidence of wounds, the Court concluded that the firing was deliberate and that the shooters must have contemplated the natural and probable consequences of their acts. The Court therefore affirmed findings of intentional causation sufficient for homicide as to Licup and attempted homicide as to Villanueva, while rejecting treachery and evident premeditation as insufficiently proven.

Dispositio

Case Syllabus (G.R. No. 120744-46)

Parties and Posture

Salvador Yapyuco y Enriquez and several co-accused filed petitions for review under Rule 45 assailing the Sandiganbayan decision in Criminal Case Nos. 16612, 16613 and 16614.
The respondents in the petitions were the Honorable Sandiganbayan and the People of the Philippines.
The cases arose from a single shooting incident on April 5, 1988 in Barangay Quebiawan, San Fernando, Pampanga that resulted in the death of Leodevince Licup and injury to Noel Villanueva.
The accused comprised INP policemen, barangay captains and CHDF or civilian volunteer officers, several of whom initially surrendered and pleaded not guilty.
The Sandiganbayan convicted some accused of homicide and attempted homicide and acquitted others, and the accused thereafter filed the present petitions contesting guilt, conspiracy findings, applicability of justifying circumstances and sufficiency of evidence.

Facts

On April 5, 1988 a green Toyota Tamaraw jeepney carrying partygoers including Leodevince Licup and Noel Villanueva was fired upon while negotiating a curve in Barangay Quebiawan.
Witnesses Eduardo Flores and Salangsang testified that no warning shots were given and that gunmen allegedly posted at the yard of a house identified as that of Lenlen Naron opened fire.
Flores testified he saw a Sarao jeepney with two armed men who conveyed the wounded to the hospital and that the jeepney’s passenger side bore bullet holes.
Forensic examination by a PNP crime laboratory chemist revealed gunpowder residue on service firearms and eleven bullet holes concentrated on the passenger side of the Tamaraw.
Medico-legal evidence by Dr. Pedro Solis recorded multiple gunshot wounds on Licup and Villanueva, with trajectories suggesting shots from oblique and perpendicular directions.
Several accused, including Yapyuco, Cunanan and Puno, submitted extrajudicial and judicial affidavits claiming they responded to a report of armed NPA elements, fired warning shots and later fired at the tires or fleeing vehicle.

Charges

The Informations charged the accused with murder in Criminal Case No. 16612, multiple attempted murder in Criminal Case No. 16613, and frustrated murder in Criminal Case No. 16614 as laid out in the respective Informations.
The Sandiganbayan ultimately convicted certain accused not of murder but of homicide under Article 249 of the Revised Penal Code and of attempted homicide under applicable provisions of the Revised Penal Code.

Evidence

Prosecution evidence comprised eyewitness testimony of Flores, Villanueva and Salangsang, the forensic report of eleven bullet holes on the Tamaraw, gunpowder residue tests, medico-legal reports of wounds and memoranda of issued service firearms.
The defense presented the testimony of Yapyuco explaining the police response to a report, his account of warning shots and the claim that other groups were positioned at Naron’s house.
Several accused elected to waive presentation of evidence or to rely on affidavits, and two material witnesses among the accused, Pamintuan and Pabalan, died before trial.
The record contained extrajudicial and judicial admissions by some accused and a sketch prepared by Flores and a sketch produced by Yapyuco purporting to show relative positions at the scene.

Issues

Whether the accused acted in lawful performance of duty under Article 11 (5) of the Revised Penal Code and thus were justified in discharging their firearms.
Whether the prosecution proved beyond reasonable doubt the identity and criminal agency of the accused in causing Licup’s death and Villanueva’s injuries.
Whether conspiracy existed among the accused to commit the unlawful attack.
Whether mistake of fact or other defenses negated criminal intent.
Whether the qualifying circumstances of treachery or evident premeditation were established.

Petitioners' Contentions

The petitioners argued that their acts were in the lawful performance of official duty and that they acted pursuant to a reasonable belief that the occupants were armed rebels.
The petitioners contended that the Sandiganbayan’s finding of conspiracy was conjectural and unsupported by direct evidence.
Some petitioners asserted denial of due process or improper reliance on evidence adduced at separate proceedings and argued that, at most, the misconduct amounted to reckless imprudence.
The petitioners invoked mistake of fact attributable to the information provided by Pamintuan and his report of NPA presence.

Prosecution's Contentions

The Office of the Special Prosecutor maintained that circumstantial and testimonial evidence established a community of purpose and design to harm the occupants as shown by bullet trajectories, positioning of accused and positive ballistic findings.
The prosecution argued that the accused exceeded any lawful exercise of duty because the use of deadly force was unnecessary and not shown to be required by the circumstances.
The prosecution further argued that waiver of separate tr
