People vs. Ruiz

The People of the Philippines cannot appeal from a judgment of conviction in a criminal case if the appeal would place the defendant in double jeopardy, as where the prosecution seeks a heavier penalty or additional punitive consequences than those imposed by the trial court. Any such appeal is barred by Section 2, Rule 122 of the Revised Rules of Court and by the constitutional prohibition against twice putting a person in jeopardy of punishment for the same offense.

After trial for homicide, the Court of First Instance of Cagayan, Branch I, presided by respondent Judge Jesus B. Ruiz, found private respondent Rodrigo Mamanao y Battung guilty but appreciated the mitigating circumstance of incomplete self-defense — there having been unlawful aggression on the part of the victim and no sufficient provocation from the accused. In view of that finding, the trial court imposed a penalty of six months and one day of imprisonment and ordered payment of civil indemnity in the amount of P4,000.00. The prosecution, deeming the penalty and indemnity inadequate, sought relief by filing a notice of appeal. Judge Ruiz declined to give due course, prompting the instant petition for mandamus to compel him to act.

• The Trial Court’s Judgment: Private respondent Rodrigo Mamanao was tried for homicide before the Court of First Instance of Cagayan, presided by respondent Judge Ruiz. The court convicted him but concurrently found that he had acted in incomplete self-defense — unlawful aggression emanated from the victim, and no sufficient provocation was attributable to Mamanao. The imposed penalty was six months and one day of imprisonment, together with civil indemnity to the heirs of the deceased fixed at P4,000.00.

• The Prosecution’s Objection and Notice of Appeal: Dissatisfied with both the duration of the penalty and the amount of indemnity, the prosecution filed a notice of appeal. The appeal aimed to secure a heavier sentence and a larger award of damages.

• Refusal to Give Due Course: Respondent Judge Ruiz declined to honor the notice of appeal. The prosecution regarded the act of transmitting the records and allowing the appeal as a purely ministerial duty, and accordingly sought a writ of mandamus from the Supreme Court.

• Solicitor General’s Position: The Office of the Solicitor General, in its Comment, opposed the petition, maintaining that the appeal would place the accused in double jeopardy and was expressly prohibited by Section 2, Rule 122 of the Rules of Court as well as by controlling jurisprudence.

• Right to Appeal under the Rules: Petitioner maintained that Rule 122 of the Revised Rules of Court permitted the prosecution to appeal from a final judgment, and that giving due course to a notice of appeal was a purely ministerial act that the trial judge could not refuse.

• Nature of Mandamus: Petitioner contended that mandamus lay to compel performance of a ministerial duty, and that no discretion was vested in the trial court to deny the appeal once a notice had been properly filed.

• Double Jeopardy Bar: Respondents, through the Solicitor General, countered that the appeal would place private respondent Mamanao in double jeopardy because the prosecution sought to increase the penalty already imposed. They pointed to the explicit prohibition in Section 2, Rule 122 of the Rules of Court and to the constitutional guarantee against double jeopardy.

• Controlling Precedent: Respondents emphasized that People v. Ang Cho Kio (95 Phil. 475) squarely ruled that the government cannot appeal when the defendant would thereby be exposed to a greater punishment for the same offense, and that subsequent cases had consistently reaffirmed that doctrine.

• Availability of Prosecution Appeal: Whether the People of the Philippines may appeal from a judgment of conviction where the practical effect would be to increase the penalty imposed upon the accused, or whether such an appeal is barred by the prohibition against double jeopardy.
• Propriety of Mandamus: Whether the trial judge could be compelled by writ of mandamus to give due course to an appeal that is prohibited by law.

• Availability of Prosecution Appeal: The prosecution’s appeal was barred by the constitutional and statutory prohibition against double jeopardy. Section 2, Rule 122 of the Revised Rules of Court is explicit: “The People of the Philippines can not appeal if the defendant would be placed thereby in double jeopardy.” The appeal sought not merely to review errors of law in the abstract but to obtain a heavier penalty and a larger indemnity — consequences that would amount to punishing the accused a second time for the same offense after a valid conviction. The controlling precedent, People v. Ang Cho Kio, established that an appeal by the prosecution from a judgment of conviction for the purpose of increasing the penalty subjects the accused to double jeopardy and is therefore impermissible. That doctrine, repeatedly reaffirmed in People v. Pae, People v. Pomeroy, and People v. Arinso, “is a mere corollary of the practice established in the Philippines and in the United States, for so long a time as to form part and parcel not merely of the settled jurisprudence, but, also, of the constitutional law, in both jurisdictions.”

• Propriety of Mandamus: Since no lawful right to appeal existed, there was no ministerial duty on the part of respondent judge to give due course to the notice. Mandamus does not lie to compel an act that would violate the Constitution or settled law.

• People v. Ang Cho Kio Doctrine — Government’s Appeal and Double Jeopardy: The government cannot appeal from a judgment of conviction in a criminal case if the defendant would thereby be placed in double jeopardy. An appeal that seeks an increase of penalty, confiscation of property, or any additional punitive consequence beyond what the trial court imposed is deemed a violation of the constitutional prohibition, even if the accused was the one convicted. The rule is rooted in the principle that a valid judgment of conviction, once rendered, vests the accused with the right to be protected from repeated attempts to punish him again for the same crime. The Supreme Court in this case applied the doctrine to defeat the prosecution’s attempt to appeal a homicide conviction where incomplete self-defense was appreciated, as the appeal manifestly aimed to secure a heavier sentence.

• Ministerial Duty and Mandamus: A writ of mandamus will issue only to compel the performance of a clear, ministerial duty imposed by law. Where the supposed duty — here, giving due course to a notice of appeal — would contravene an express provision of the Rules of Court and the Constitution, no ministerial duty exists, and mandamus will not lie.

• “The People of the Philippines can not appeal if the defendant would be placed thereby in double jeopardy. In all other cases either party may appeal from a final judgment or ruling or from an order made after judgment affecting the substantial rights of the appellant.” (Section 2, Rule 122 of the Revised Rules of Court, quoted as the controlling statutory text.)

• “Creemos que en el caso presente se pone al acusado en double jeopardy, esto es en el peligro de recibir la condena de reclusion perpetua despues de haber sido condenado ya por el juzgado inferior a una pena menor.” (Excerpt from People v. Ang Cho Kio, 95 Phil. 475, 480-481, articulating the core risk that an appeal by the prosecution subjects the accused to a second jeopardy for the same offense.)

• “The reasons advanced by the Solicitor General in support of his pretense are not sufficiently weighty to warrant a reversal of said view which is a mere corollary of the practice established in the Philippines and in the United States, for so long a time as to form part and parcel not merely of the settled jurisprudence, but, also, of the constitutional law, in both jurisdictions.” (From People v. Pomeroy, 97 Phil. 927, 94, quoted in the decision to underscore that the Ang Cho Kio rule is a constitutionally embedded principle, not an ordinary procedural rule.)

• People v. Ang Cho Kio, 95 Phil. 475 (1954) — Controlling precedent and followed. Established that the government may not appeal if the defendant would be placed in double jeopardy, which includes the risk of a heavier penalty after a valid conviction.
• People v. Pae, 100 Phil. 357 (1956) — Reaffirmed Ang Cho Kio; held that seeking confiscation of money as an additional penalty on appeal would place the accused in double jeopardy.
• People v. Pomeroy, 97 Phil. 927 (1955) — Declined to reconsider Ang Cho Kio; characterized the rule as a constitutional law corollary, not merely procedural.
• People v. Arinso, 99 Phil. 538 (1956) — Again refused to depart from the Ang Cho Kio ruling.

• Section 2, Rule 122 of the Revised Rules of Court (now Section 1, Rule 122, 2000 Rules of Criminal Procedure): Explicitly bars the People from appealing if the defendant would be placed in double jeopardy; applied as the direct statutory prohibition against the prosecution’s appeal.
• Article IV, Section 22 of the 1973 Constitution (now Article III, Section 21, 1987 Constitution): “No person shall be twice put in jeopardy of punishment for the same offense.” Invoked as the constitutional foundation of the prohibition, rendering the prosecution’s attempt to increase the penalty via appeal an impermissible second jeopardy.

Justices Barredo, Antonio, Aquino, and Concepcion, Jr. concurred. Justice Santos was on leave.
