People vs. San Juan

Self-defense cannot be appreciated when unlawful aggression has ceased, and a diagnosis of schizophrenia made after the commission of the crime cannot exempt an accused from criminal liability absent proof of abnormal behavior immediately before or simultaneous to the offense. Treachery and evident premeditation cannot rest on conjecture but must be grounded on facts of unquestionable existence, and their absence reduces the killing from murder to homicide.

The accused, Ernesto San Juan y Dela Peña (alias "Nestor Buwang" or "Totoy Buwang"), and the victim, Bernardo Cortez y Cezar, were acquaintances in the Paco, Manila area, known to drink together with a group of men on Salvador Street where the barangay hall was located. The accused had previously given the victim work, and a dispute over that employment became the source of tension between them. The case was appealed directly to the Supreme Court from the Regional Trial Court's conviction for murder.

At around 1:30 a.m. on January 13, 1996, Barangay Chairman Cesar Lopez was at Leroy Street, Barangay 679, Zone 74, District 5, Paco, Manila, when a commotion drew his attention. From about eight meters away in a well-lighted area, he saw a person stab another, though the assailant's back was toward him. The culprit fled immediately. Lopez approached the victim, recognized him as Bernardo Cortez, and was told by the dying man that he was stabbed by "Totoy Buwang." Cortez appeared weak and very pale. Lopez, together with two barangay tanods, rushed Cortez to the Philippine General Hospital, but the victim was already dead upon arrival. Two to three days later, between 2:00 a.m. and 3:00 a.m., Lopez and two policemen found the accused, Ernesto San Juan, at the corner of Paz and Trece de Agosto Streets and apprehended him. Lopez identified the accused in court as the only person known as "Totoy Buwang" in their barangay.

Valentino Socorro, Chief Barangay Tanod, corroborated the account. At around 2:30 a.m. on the same date, while on duty at the door of the barangay hall on Salvador Street, he saw Cortez running toward the hall with a stab wound below his left breast, crying for help. Socorro also saw the accused running from Salvador Street to Trece de Agosto Street. Socorro and a companion known as Tikoy transported Cortez to the Philippine General Hospital on a pedicab. During the thirty-minute trip, Socorro asked Cortez who stabbed him, and the latter replied that it was "Ernesto Buwang," uttering, "Tulungan ninyo ako at sinaksak ako ni Ernesto Buwang." Cortez was still alive when they reached the hospital but expired the following day.

The accused took the witness stand and admitted stabbing Cortez. According to his testimony, on January 13, 1996, Cortez went to his house near the Paco Church, where they had a heated exchange of words concerning the work the accused had given Cortez. Cortez boxed him on the forehead, leaving a scar the accused displayed to the court. On cross-examination, the accused added that Cortez also had a fan knife and stabbed him on the left side of his face. The accused gave conflicting accounts of when he retaliated: in one part of his testimony, he stated that he retaliated on the same day, while in another, he said it was after one week. He stabbed Cortez on the left side of the body with a knife, learned that same day that Cortez had died, and then surrendered to his parents and the Manila Police, telling them he killed Cortez in self-defense.

The trial court convicted the accused of murder qualified by treachery and evident premeditation, finding that the victim was sleeping when stabbed. The accused appealed to the Supreme Court. Before filing his Brief, his PAO lawyers discovered a Medical Certificate dated October 6, 1997, prepared by Senior Inspector and Medical Officer Arthur G. Lorenzo of the Bureau of Jail Management and Penology, diagnosing the accused with "R/O Schizophrenia." The certificate had not been formally offered in the lower court, prompting a Motion to Remand for further reception of evidence on the accused's insanity at the time of the crime.

The accused-appellant is the party who appealed; the People of the Philippines is the appellee. As the appellee's arguments are set forth below, the accused-appellant's arguments are summarized here.

• Insufficiency of Evidence: The accused-appellant argued that the prosecution's evidence was insufficient to establish beyond reasonable doubt that he was Cortez's assailant.
• Excessive and Unfounded Damages: The accused-appellant maintained that, assuming guilt, the trial court erred in awarding damages that were excessive and bereft of factual and legal basis.
• Motion to Remand for Insanity Defense: The accused-appellant's PAO lawyers argued that a Medical Certificate dated October 6, 1997 diagnosing him with "R/O Schizophrenia" was attached to the case records but was not formally offered by the previous PAO counsel, and prayed for remand to receive evidence on his insanity at the time of the commission of the crime, invoking substantial justice.

• Insanity Evidence Irrelevant to Time of Crime: The Solicitor General countered that the medical certificate, even if admitted, would only prove the accused's mental condition on October 6, 1997, and not at the time the crime was committed on January 13, 1996, over a year prior.
• Willful and Voluntary Act: The Solicitor General argued that the accused consciously admitted in court that he stabbed Cortez with a knife allegedly in retaliation for being boxed on the forehead, indicating that the accused understood the nature and consequences of his act, which was willfully, voluntarily, and knowingly executed.
• Procedural Flaw in Motion to Remand: The Solicitor General maintained that the Motion to Remand was procedurally flawed, as a motion to reopen a case is proper only after either or both parties have formally offered and closed their evidence but before judgment.
• Recommendation to Lower to Homicide: The Solicitor General recommended that, in the absence of any aggravating circumstance to qualify the killing to murder, the crime should be lowered to homicide.

• Identity of Assailant: Whether the prosecution's evidence was sufficient to establish beyond reasonable doubt that the accused was the victim's assailant, notwithstanding the accused's admission of the stabbing.
• Self-Defense: Whether the accused's claim of self-defense was valid, particularly whether unlawful aggression existed at the time of the stabbing.
• Insanity Defense / Motion to Remand: Whether the case should be remanded to the court a quo for reception of evidence on the accused's insanity based on a medical certificate issued after the commission of the crime.
• Qualifying Circumstances: Whether treachery and evident premeditation were properly appreciated to qualify the killing to murder.
• Damages: Whether the damages awarded by the trial court were proper in amount and supported by factual and legal basis.

• Identity of Assailant: Yes. The accused admitted in his testimony that he stabbed the victim, thereby assuming the burden of proving self-defense and foreclosing any challenge to the identity of the assailant.
• Self-Defense: No. Unlawful aggression, an indispensable element of self-defense, had ceased at the time of the stabbing, as the accused either retaliated later the same day or a full week after being boxed, with no proof of continued aggression by the victim.
• Insanity Defense / Motion to Remand: No. The motion was denied because evidence of insanity must relate to the time preceding or coetaneous with the commission of the offense, and the medical certificate issued on October 6, 1997 did not establish the accused's mental state on January 13, 1996.
• Qualifying Circumstances: No. Treachery was not proved because no evidence was presented on the manner of attack, and evident premeditation failed for lack of proof of its three elements; the conviction was accordingly reduced from murder to homicide.
• Damages: Partially sustained. Civil indemnity of ₱50,000 was affirmed; moral damages were reduced from ₱200,000 to ₱50,000; nominal damages were reduced from ₱100,000 to ₱10,000, the award of nominal damages being proper to vindicate a violated right notwithstanding the concurrent award of civil indemnity and moral damages.

• Identity of Assailant: The accused testified and admitted that he stabbed Cortez with a knife. Having invoked self-defense, he assumed the onus probandi to substantiate its elements clearly and convincingly under Article 11, paragraph 1 of the Revised Penal Code. The issue of identity was therefore foreclosed by his own admission, and the prosecution's evidence on this point—corroborated by the testimonies of Socorro and Lopez—was sufficient.

• Self-Defense: Unlawful aggression is an indispensable element of self-defense, whether complete or incomplete under Articles 11 or 13 of the Revised Penal Code. It refers to an actually materialized attack or, at the very least, a clearly imminent attack. When unlawful aggression has ceased, the one making a defense has no right to kill or injure the former aggressor. The accused's testimony was uncorroborated and internally inconsistent: in one part, he stated that he stabbed Cortez on the same day without indicating the interval between the boxing and the stabbing; in another, he stated that he retaliated after one week. In either case, there was no proof of continued unlawful aggression on the part of Cortez at the time of the stabbing. The accused's theory of self-defense therefore failed, whether as a justifying circumstance under Article 11 or a mitigating circumstance under Article 13.

• Insanity Defense / Motion to Remand: The medical certificate dated October 6, 1997 diagnosed the accused with "R/O Schizophrenia" nearly two years after the crime was committed on January 13, 1996. Pursuant to People vs. Madarang, evidence of insanity must relate to the time preceding or coetaneous with the commission of the offense. Although a post-offense diagnosis may be accorded weight, it requires proof of abnormal behavior immediately before or simultaneous to the commission of the crime. No such proof was presented. Moreover, the accused's conscious admission that he stabbed Cortez in retaliation indicated that he understood the nature and consequences of his act. The motion to remand was also procedurally flawed, as a motion to reopen is proper only after the parties have formally offered and closed their evidence but before judgment.

• Qualifying Circumstances: The trial court found the accused guilty of murder qualified by treachery and evident premeditation, reasoning that the victim was sleeping when stabbed. This finding was erroneous. For treachery to be appreciated, the manner of attack must be proved; without particulars on how the aggression commenced or how the act resulting in death unfolded, treachery cannot be appreciated. Circumstances qualifying criminal responsibility cannot rest on mere conjectures but must be based on facts of unquestionable existence. No evidence was presented that the victim was sleeping when stabbed. Evident premeditation likewise failed because there was a dearth of evidence on its three elements: (1) the time when the accused decided to commit the crime; (2) an overt act manifestly indicating that he clung to his determination; and (3) a sufficient lapse of time between decision and execution to allow reflection. In the absence of any qualifying circumstance, the Solicitor General's recommendation to lower the crime to homicide was adopted.

• Damages: The trial court correctly ordered the accused to pay civil indemnity of ₱50,000 for the loss of the victim's life. The grant of moral damages was reduced from ₱200,000 to ₱50,000 in accordance with prevailing jurisprudence. Nominal damages were sustained over the Solicitor General's objection that they should be deleted because civil indemnity and moral damages had already been awarded. Nominal damages are awarded to vindicate a violated right, not for indemnification, and the award of civil indemnity and moral damages does not preclude their recovery. The amount was, however, reduced from ₱100,000 to ₱10,000.

• Unlawful Aggression as Indispensable Element of Self-Defense — Unlawful aggression is an indispensable element of self-defense, whether complete under Article 11 or incomplete under Article 13 of the Revised Penal Code. It refers to an actually materialized attack or, at the very least, a clearly imminent attack. When unlawful aggression has ceased, the defender has no right to kill or injure the former aggressor. In this case, the accused failed to prove that the victim's aggression persisted at the time of the stabbing, as the accused himself testified that he retaliated either later the same day or a full week after being boxed.

• Insanity Defense Must Relate to the Time of the Offense — Evidence of insanity must relate to the time preceding or coetaneous with the commission of the offense charged. A diagnosis of mental illness made after the commission of the crime may be accorded weight only if there is also proof of abnormal behavior immediately before or simultaneous to the commission of the crime. The medical certificate diagnosing the accused with schizophrenia was issued nearly two years after the stabbing and, absent any evidence of abnormal behavior at the time of the offense, could not support an exemption from criminal liability.

• Treachery Requires Proof of Manner of Attack — For treachery to be appreciated, the manner of attack must be proved. Without particulars on how the aggression commenced or how the act resulting in death unfolded, treachery cannot be appreciated. Circumstances qualifying criminal responsibility cannot rest on mere conjectures, no matter how reasonable or probable, but must be based on facts of unquestionable existence. The trial court's finding that the victim was sleeping was unsupported by any evidence.

• Elements of Evident Premeditation — The three elements of evident premeditation are: (1) the time when the accused decided to commit the crime; (2) an overt act manifestly indicating that he has clung to his determination; and (3) a sufficient lapse of time between the decision and execution to allow the accused to reflect upon the consequences of his act. All three must be proved; the absence of evidence on any element precludes appreciation of the circumstance.

• Nominal Damages Vindicate Rights, Not Indemnify — Nominal damages are awarded so that a right which has been violated may be recognized or vindicated, and not for the purpose of indemnification. The award of civil indemnity and moral damages does not preclude the recovery of nominal damages, as they serve distinct purposes.

• "Unlawful aggression is an indispensable element of self-defense, whether complete or incomplete under Articles 11 or 13, respectively." — This passage states the controlling rule on self-defense and explains why the accused's claim failed: the aggression had ceased before the stabbing occurred.

• "the evidence of insanity must relate to the time preceding or coetaneous with the commission of the offense with which he is charged." — This formulation, drawn from People vs. Madarang, defines the temporal requirement for an insanity defense and is the basis for denying the motion to remand.

• "Circumstances qualifying criminal responsibility cannot rest on mere conjectures, no matter how reasonable or probable, but must be based on facts of unquestionable existence." — This passage articulates the evidentiary standard for qualifying circumstances and underpins the Court's rejection of treachery as applied by the trial court.

• "Nominal damages are awarded so that a right which has been violated may be recognized or vindicated, and not for the purpose of indemnification." — This defines the purpose of nominal damages and explains why their award is not precluded by concurrent awards of civil indemnity and moral damages.

• People vs. Madarang, 332 SCRA 99 (2000) — Controlling authority on the temporal requirement for evidence of insanity, holding that it must relate to the time preceding or coetaneous with the commission of the offense. Followed in denying the motion to remand.

• People vs. Borreros, 306 SCRA 680 (1999) — Cited for the proposition that when an accused invokes self-defense, the burden of proof shifts to him, and for the definition of unlawful aggression as a materialized or clearly imminent attack. Followed.

• People vs. Antonio, 303 SCRA 414 (1999) — Cited for the rule that unlawful aggression is an indispensable element of self-defense. Followed.

• People vs. Anacan, G.R. No. 144318, April 3, 2002 — Cited as basis for the indeterminate sentence imposed for homicide. Followed.

• Article 11, paragraph 1, Revised Penal Code — Defines self-defense as a justifying circumstance, requiring (1) unlawful aggression, (2) reasonable necessity of the means employed to prevent or repel it, and (3) lack of sufficient provocation on the part of the person defending himself. Applied to test the accused's claim; the first element was not satisfied.

• Article 13, paragraph 1, Revised Penal Code — Provides that circumstances mentioned in the preceding chapter (justifying circumstances) serve as mitigating circumstances when all the requisites necessary to justify the act are not attendant. Applied to test whether incomplete self-defense could mitigate liability; it could not, because unlawful aggression was absent.

• Article 248, Revised Penal Code — Defines and penalizes murder, as qualified by treachery and evident premeditation among other circumstances. The trial court applied this provision, but the Supreme Court found the qualifying circumstances unproved and reduced the conviction to homicide under Article 249.
