People vs. Gaborne

Objections to the legality of an arrest are deemed waived where the accused enters a plea and actively participates in trial without raising the objection; furthermore, the use of an unlicensed firearm in the commission of murder constitutes a special aggravating circumstance rather than a separate offense, and the existence of the firearm may be established by testimonial evidence notwithstanding its non-presentation as physical evidence.

On the evening of February 2, 2007, Rey Perfecto De Luna and Sixto Elizan were drinking and singing at a videoke bar in Barangay Mugdo, Hinabangan, Samar. Luisito Gaborne, together with Noli Abayan and Joselito Bardelas, arrived shortly thereafter. Without provocation, gunshots were fired through the window of the establishment, striking Elizan and De Luna from behind. Elizan died from his wounds, while De Luna survived following emergency medical treatment. Prosecution eyewitnesses positively identified Gaborne as the assailant holding a firearm immediately after the shooting.

• The Incident: On February 2, 2007, at approximately 10:30 p.m., victims Rey Perfecto De Luna and Sixto Elizan were at a videoke bar in Barangay Mugdo, Hinabangan, Samar. Appellant Luisito Gaborne, together with Noli Abayan and Joselito Bardelas, entered the establishment five minutes later. While the victims were drinking and singing, four successive gunshots were fired through the window from outside, striking both victims from behind.
• Eyewitness Identification: Prosecution witness Marialinisa Pasana and victim Rey Perfecto De Luna testified that they saw appellant Gaborne, wearing a black t-shirt and black cap, holding a gun aimed at their location immediately after the shooting. Pasana also witnessed Gaborne and Bardelas fleeing the scene.
• Medical Evidence: Elizan was pronounced dead upon arrival at St. Paul's Hospital in Tacloban City. De Luna sustained gunshot wounds to the back and para-spinal area but survived due to timely surgical intervention. Dr. Angel Cordero testified that De Luna would have died absent immediate medical treatment.
• Defense Evidence: Appellant denied involvement, claiming that he and Bardelas had stepped outside to urinate when the waitress locked the door. He alleged hearing the waitress threaten to have them killed, and claimed that an unidentified man wearing a black shirt and camouflage pants was the actual shooter. He denied possessing a firearm or having motive to kill the victims.
• Paraffin Test: Appellant was arrested on February 3, 2007, and subjected to a paraffin test which yielded negative results for gunpowder nitrates.
• Firearm License: Certification from the Philippine National Police established that appellant was not a licensed firearm holder of any caliber.

• Legality of Arrest: Appellant argued that his arrest was illegal, contending that the arresting officers lacked a warrant and that the warrantless arrest did not fall under the recognized exceptions under Rule 113 of the Rules of Court.
• Insufficiency of Evidence: Appellant maintained that the prosecution failed to establish his guilt beyond reasonable doubt, asserting that the negative paraffin test result contradicted the eyewitness testimony that he fired a weapon.
• Lack of Corpus Delicti for Unlicensed Firearm: Appellant contended that the prosecution failed to establish the corpus delicti of illegal possession of firearm because the actual weapon was never presented as evidence.
• Denial and Alibi: Appellant argued that his defense of denial and alibi—that he was outside the videoke bar when the shooting occurred—should be given credence over the prosecution's evidence, and that the absence of motive supported his innocence.

• Waiver of Objection: Respondent People of the Philippines countered that appellant was estopped from questioning the legality of his arrest because he failed to move for the quashal of the Information before arraignment and actively participated in trial, thereby voluntarily submitting to the court's jurisdiction.
• Positive Identification: Respondent argued that the positive identification by eyewitnesses Pasana and De Luna, who had sufficient opportunity to observe the appellant at the scene, outweighed the defense of denial and alibi.
• Treachery: Respondent maintained that the element of treachery was present where the victims were shot from behind without warning while engaged in harmless activity, eliminating any risk to the appellant from defensive action.
• Frustrated Murder: Respondent contended that the appellant performed all acts of execution necessary to cause death, and the victim's survival was due solely to timely medical intervention, constituting a cause independent of the appellant's will.
• Unlicensed Firearm: Respondent argued that the existence of the firearm and appellant's lack of license were established by testimonial evidence and official certification, sufficient to prove the aggravating circumstance even without physical presentation of the weapon.

• Legality of Arrest: Whether the appellant may challenge the legality of his arrest for the first time on appeal.
• Treachery: Whether the killing was attended by treachery qualifying it to murder.
• Frustrated Murder: Whether the crime committed against De Luna constituted frustrated murder.
• Credibility of Witnesses: Whether the positive identification by prosecution eyewitnesses prevails over the appellant's defense of denial and alibi.
• Paraffin Test: Whether a negative paraffin test result negates positive eyewitness identification.
• Unlicensed Firearm: Whether the use of an unlicensed firearm constitutes a separate offense or merely a special aggravating circumstance when murder results therefrom.
• Damages: Whether the awards of civil indemnity, moral, and exemplary damages were proper.

• Legality of Arrest: Objections to the legality of an arrest or the court's acquisition of jurisdiction over the person of the accused are deemed waived where the accused enters a plea and participates in trial without raising such objections; voluntary submission to jurisdiction cures any irregularity in the arrest.
• Treachery: Treachery was established where the appellant shot the victims from behind through a window while they were drinking and singing, employing means that ensured execution without risk to himself and without affording the victims opportunity to defend themselves or retaliate.
• Frustrated Murder: The crime constituted frustrated murder because the appellant performed all acts of execution which would have produced death as a consequence, but failed to do so by reason of a cause independent of his will—the timely and able medical treatment rendered to De Luna.
• Credibility of Witnesses: Positive identification by credible eyewitnesses who testified that they saw appellant holding a gun immediately after the shooting outweighs the inherently weak defense of denial and alibi; motive is irrelevant where positive identification exists.
• Paraffin Test: Paraffin tests are inconclusive and scientifically unreliable to determine firearm discharge; a negative result does not negate positive eyewitness testimony, particularly where the appellant was arrested a day after the incident, allowing time for the removal of gunpowder residue through washing or perspiration.
• Unlicensed Firearm: Under Republic Act No. 8294 and Republic Act No. 10591, the use of an unlicensed firearm in the commission of murder constitutes a special aggravating circumstance, not a separate offense; separate prosecution for illegal possession is no longer required where homicide or murder results, and the existence of the firearm may be proven by testimonial evidence and certification of non-license.
• Damages: The awards were modified to conform with prevailing jurisprudence: for Murder, ₱100,000.00 each for civil indemnity, moral damages, and exemplary damages; for Frustrated Murder, ₱75,000.00 each for civil indemnity, moral damages, and exemplary damages; all subject to six percent interest per annum from finality until full payment.

• Waiver of Objection to Illegal Arrest — Any objection involving a warrant of arrest or the procedure by which the court acquired jurisdiction over the person of the accused must be made before entering a plea; otherwise, the objection is deemed waived. Active participation in arraignment and trial constitutes voluntary submission to jurisdiction, curing any procedural defect in the arrest.
• Elements of Treachery — Treachery requires: (1) employment of means, method, or manner of execution that ensures the safety of the malefactor from defensive or retaliating acts, with no opportunity given to the victim to defend himself; and (2) deliberate or conscious adoption of such means, method, or manner.
• Frustrated Felony — A felony is frustrated when the offender performs all acts of execution which would produce the felony as a consequence but which do not produce it by reason of causes independent of the will of the perpetrator.
• Reliability of Paraffin Tests — Paraffin tests are scientifically inconclusive in determining whether a person fired a firearm, as nitrates may originate from sources other than gunpowder and residue may be removed by washing or perspiration; negative results do not overcome positive eyewitness identification.
• Illegal Possession of Firearm as Aggravating Circumstance — Pursuant to R.A. No. 8294 and R.A. No. 10591, when homicide or murder is committed with the use of an unlicensed firearm, the offense of illegal possession is absorbed as a special aggravating circumstance; the penalty for illegal possession is no longer imposable separately. The elements may be proven by testimonial evidence and official certification of non-license without presenting the physical firearm.

• "Any objection involving a warrant of arrest or the procedure by which the court acquired jurisdiction over the person of the accused must be made before he enters his plea; otherwise, the objection is deemed waived." — Establishing the procedural rule that defects in arrest are cured by voluntary submission to jurisdiction.
• "Paraffin tests, in general, have been rendered inconclusive by this Court. Scientific experts concur in the view that the paraffin test was extremely unreliable for use. It can only establish the presence or absence of nitrates or nitrites on the hand; however, the test alone cannot determine whether the source of the nitrates or nitrites was the discharge of a firearm." — On the limited probative value of paraffin tests.
• "The intent of Congress is to treat the offense of illegal possession of firearm and the commission of homicide or murder with the use of unlicensed firearm as a single offense." — Explaining the legislative intent behind R.A. No. 8294 and R.A. No. 10591 regarding the treatment of unlicensed firearm use as an aggravating circumstance rather than a separate crime.

• People v. Velasco, 722 Phil. 243 (2013) — Cited for the doctrine that failure to move for quashal of the Information before arraignment estops the accused from assailing the legality of arrest.
• People v. Lualhati, G.R. Nos. 105289-90, 234 SCRA 325 (1994) — Established the elements necessary to prove illegal possession of firearm: existence of the firearm and lack of license.
• People v. Orehuela, G.R. Nos. 108780-81, 232 SCRA 82 (1994) — Held that the existence of a firearm may be established by testimony even without physical presentation of the weapon.
• People v. Jugueta, G.R. No. 202124 (2016) — Prevailing jurisprudence on the amounts of damages for murder and frustrated murder cases.
• Kummer v. People, 717 Phil. 670 (2013) — Held that motive is irrelevant when the accused has been positively identified by an eyewitness.

• Article 248, Revised Penal Code — Defines murder and enumerates qualifying circumstances including treachery; penalty is reclusion temporal in its maximum period to death.
• Article 50, Revised Penal Code — Penalizes frustrated felonies by one degree lower than the consummated felony.
• Article 14(16), Revised Penal Code — Defines treachery as an aggravating circumstance.
