People vs. Court of Appeals and Maquiling

A judgment of acquittal may be set aside through a petition for certiorari under Rule 65 only when the petitioner proves that the court a quo acted with grave abuse of discretion amounting to lack or excess of jurisdiction, or denied due process. Errors in the appreciation of evidence and factual findings are mere errors of judgment, not errors of jurisdiction; they cannot be corrected by certiorari without trenching upon the constitutional prohibition against double jeopardy.

Casan Maquiling was charged following a shooting incident that occurred after a fight at a disco in Iligan City on June 3, 1988. The altercation began between Maquiling’s younger brother Ramil and Frederick Pacasum. Casan Maquiling intervened, was boxed, and later a gunfight erupted outside the venue. Pacasum died from gunshot wounds; another person, Oligario Villarimo, was wounded. The prosecution charged Maquiling with homicide and serious physical injuries. At trial, Maquiling admitted the shooting but claimed self-defense, alleging that Pacasum had fired a shotgun at him first. The trial court rejected the defense and convicted him. The Court of Appeals reversed, finding that the prosecution failed to disprove self-defense, and acquitted him. The People then elevated the matter to the Supreme Court via certiorari, contending that the acquittal was void for grave abuse of discretion and denial of due process.

• The Incident According to the Prosecution: Inside the Spectrum Disco, Ramil Maquiling boxed Frederick Pacasum, who boxed back. Casan Maquiling, Ramil’s elder brother, appeared and boxed Pacasum as well. The Maquiling brothers ran outside; Pacasum and his companions followed. Another fist fight ensued. Casan Maquiling went to his parked Isuzu Trooper, retrieved a .45 caliber pistol, and approached the deceased. Audie Pacasum tried to stop him. Maquiling fired a warning shot, scattering the crowd. Pacasum turned to look, and Maquiling shot him twice in the left thigh. After Pacasum fell, Maquiling approached and fired a third shot into his chest, killing him. Oligario “Jojo” Villarimo was also shot in the leg.

• The Incident According to the Defense: Inside the disco, Frederick Pacasum boxed Ramil Maquiling, hit him with a bottle, and kicked him repeatedly. Casan Maquiling attempted to intervene but was boxed on the right cheek. Because Pacasum’s companions were larger and more numerous, Casan backed away and left the disco. He walked to his vehicle parked about twelve meters from the entrance. Pacasum followed him, holding a shotgun at hip level and pointing it at him. Casan opened his vehicle, grabbed his .45 pistol, and fired two warning shots. Pacasum’s brother shouted, “Barilin mo na.” Pacasum fired the shotgun, hitting Casan in the hip. Casan fell to his knees and elbows. From a kneeling position, he shot Pacasum twice in the hip, intending only to disarm him. When Pacasum continued aiming the shotgun, Casan, having no other choice, shot him in the chest. Villarimo ran to pick up the shotgun; Casan shot him in the leg to disarm him.

• Physical Evidence and Trial Court Findings: The autopsy showed gunshot wounds on Pacasum’s left thigh and chest, with a downward trajectory. The trial court disbelieved the self-defense claim, convicted Maquiling of homicide and serious physical injuries, and gave weight to the prosecution’s account that the accused was the aggressor.

• Appellate Court’s Reassessment: The Court of Appeals found that the defense evidence established the three requisites of self-defense: unlawful aggression (Pacasum aiming and firing a shotgun at the accused), reasonable necessity of the means (warning shots, then shots to the thigh followed by a fatal shot only when the threat persisted), and lack of sufficient provocation (Pacasum approached the accused with a shotgun, ignoring warning shots, and fired first). The CA noted material inconsistencies in the prosecution witnesses’ testimonies, which weakened their credibility, and observed that the gunshot wound sustained by Maquiling—unexplained by the prosecution—was the best evidence of an exchange of gunfire.

• Grave Abuse of Discretion — Misappreciation of Evidence: Petitioner argued that the Court of Appeals committed manifest bias by ignoring and discarding uncontroverted physical evidence that the trial court had relied upon, particularly the downward trajectory of the bullets, which showed that Maquiling was standing when he shot the victims, and his own shotgun wound, which allegedly disabled him. The CA was said to have harped on insignificant inconsistencies in prosecution testimony while unquestioningly accepting Maquiling’s self-serving claim of self-defense.

• Shifting of the Burden of Proof and Failure to Consider Escape: Petitioner maintained that the CA failed to discuss the effect of Maquiling’s escape from confinement during the pendency of the case and effectively shifted the burden of proof onto the prosecution, despite Maquiling’s admission of the killing and his invocation of self-defense.

• Denial of Due Process: Petitioner contended that the appellate court denied due process when it reviewed the trial court’s assessment of the credibility of witnesses, even though that matter had not been raised as an issue in the appeal brief.

• Certiorari as Improper Remedy: Respondent Maquiling argued that the petition merely assailed the appellate court’s appreciation of evidence and credibility of witnesses, which are errors of judgment correctible only through an appeal, not by certiorari. The acquittal had been rendered after a full review of the evidence and within the CA’s jurisdiction; no grave abuse of discretion or denial of due process was shown.

• Double Jeopardy Bar: Respondent further maintained that the acquittal was final and that any review of the CA’s factual conclusions would place him in double jeopardy, in violation of the Constitution and the Rules of Court.

• Grave Abuse of Discretion: Whether the Court of Appeals committed grave abuse of discretion amounting to lack or excess of jurisdiction in reversing the trial court’s conviction and acquitting Maquiling on the ground of self-defense, thereby rendering its decision void and susceptible to certiorari.

• Denial of Due Process: Whether the prosecution was denied due process when the Court of Appeals reviewed the trial court’s assessment of witness credibility, despite such matter not having been assigned as an error in the appeal brief.

• Grave Abuse of Discretion: No grave abuse of discretion attended the acquittal. The petition alleged that the CA misappreciated factual evidence—failing to give proper weight to physical evidence, disregarding prosecution testimony, and erroneously finding self-defense. These are errors of judgment, not errors of jurisdiction. Certiorari under Rule 65 is confined to correcting jurisdictional errors; it cannot be used to review a court’s evaluation of evidence and factual findings. The Court of Appeals’ determination that the three requisites of self-defense were present was based on the defense evidence, not on caprice or whim. Even assuming the appellate court committed a mistake in judgment, such an error does not vitiate the decision or oust the court of jurisdiction. A writ of certiorari will not issue to correct mere errors in the lower court’s findings or conclusions.

• Denial of Due Process: No denial of due process occurred. It is a basic rule that an appeal in a criminal case opens the entire case for review; the appellate court can correct errors even if they were not specifically assigned by the parties. The Court of Appeals did not receive new evidence, and the prosecution was not deprived of an opportunity to be heard on any matter already in the record. Reviewing the trial court’s assessment of credibility was well within the appellate court’s jurisdiction and did not violate due process.

• Certiorari versus Appeal — Certiorari corrects errors of jurisdiction, not errors of judgment. A misappreciation of evidence or an erroneous assessment of facts is an error of judgment, which is properly the subject of an appeal, not a special civil action for certiorari. To warrant the issuance of the writ, the abuse of discretion must be grave — i.e., capricious, whimsical, arbitrary, or despotic, equivalent to lack of jurisdiction. Mere errors in the evaluation of evidence, even if they result in an incorrect decision, do not amount to grave abuse of discretion.

• Double Jeopardy and Acquittal — An acquittal based on the merits is final and unappealable. The prosecution may not appeal or seek review of a judgment of acquittal; doing so would place the accused in double jeopardy, which attaches when (1) the accused is charged under a valid complaint or information, (2) the court has jurisdiction, (3) the accused has been arraigned and pleaded, and (4) the accused is convicted or acquitted, or the case is dismissed without express consent. An acquittal rendered with grave abuse of discretion or without due process is void and does not trigger double jeopardy because it lacks legal existence. However, where the petition merely demonstrates errors of judgment, the constitutional prohibition against double jeopardy bars further review.

• Open-Case Doctrine in Criminal Appeals — An appeal in a criminal case throws the entire case open for review. The appellate court may examine the whole record and correct errors, including those not assigned by the parties, and may even reverse on grounds other than those raised. This does not constitute a denial of due process as long as no new evidence is admitted and the parties are not deprived of an opportunity to be heard on matters already of record.

• “The rule against double jeopardy proscribes an appeal from a judgment of acquittal. If said judgment is assailed in a petition for certiorari under Rule 65 of the Rules of Court, as in the present case, the petitioner must prove that the lower court, in acquitting the accused, committed not merely reversible errors, but grave abuse of discretion amounting to lack or excess of jurisdiction.”

• “A judgment rendered with grave abuse of discretion or without due process is void, does not exist in legal contemplation and, thus, cannot be the source of an acquittal. However, where the petition demonstrates mere errors in judgment not amounting to grave abuse of discretion or deprivation of due process, the writ of certiorari cannot issue. A review of the alleged errors of judgment cannot be made without trampling upon the right of the accused against double jeopardy.”

• “Certiorari will issue only to correct errors of jurisdiction, not errors of procedure or mistakes in the findings or conclusions of the lower court. As long as a court acts within its jurisdiction, any alleged errors committed in the exercise of its discretion will amount to nothing more than errors of judgment, which are reviewable by timely appeal and not by special civil action for certiorari.”

• “Basic is the rule that an appeal in a criminal case throws the whole case wide open for review; and that the appellate court can correct errors, though unassigned, that may be found in the appealed judgment. The appeals court may even reverse the trial court’s decision on the basis of grounds other than those that the parties raised as errors.”

• U.S. v. Kepner, 11 Phil. 669 (1904) / 195 U.S. 100 — The foundational ruling that an appeal by the prosecution from a judgment of acquittal places the accused in double jeopardy. This case was the origin of the rule incorporated in Philippine law and remained controlling.

• People v. Bocar, 138 SCRA 166 (1985) — Enumerated the four elements of double jeopardy; relied upon to confirm that an acquittal by a court of competent jurisdiction ordinarily bars further prosecution.

• Commissioner of Internal Revenue v. Court of Appeals, 257 SCRA 200 (1996) — Defined grave abuse of discretion as a capricious or whimsical exercise of judgment equivalent to lack of jurisdiction; cited for the standard required to set aside an acquittal via certiorari.

• People v. Reyes, G.R. No. 91262, January 28, 1998 — Affirmed the rule that an appeal in a criminal case opens the whole case for review, allowing the appellate court to correct unassigned errors.

• Section 2, Rule 122, Rules of Court — “Any party may appeal from a final judgment or order, except if the accused would be placed thereby in double jeopardy.” This provision codifies the prohibition against prosecution appeals from acquittals based on the merits. Applied to bar the People from directly appealing the CA’s acquittal and to confine its remedy to certiorari only upon showing of grave abuse of discretion or denial of due process.

• Section 21, Article III, 1987 Constitution — “No person shall be twice put in jeopardy of punishment for the same offense.” Invoked as the constitutional foundation for the double jeopardy rule. The Court held that reviewing the CA’s factual findings and sustaining the petition would place Maquiling in jeopardy a second time, in violation of this provision.
