At least, the mistakes ascribed to the trial court are not errors of jurisdiction correctible by the special civil action for certiorari, but errors of judgment, which is correctible by a petition for review on certiorari under Rule 45 of the Revised Rules of Court. The mere fact that a court erroneously decides a case does not necessarily deprive it of jurisdiction. Thus, assuming arguendo that the trial court committed a mistake in its judgment, the error does not vitiate the decision, considering that it has jurisdiction over the case.[27] For this reason, the dismissal of the instant petition is called for.
In our jurisdiction, availment of the remedy of certiorari to correct an erroneous acquittal may be allowed in cases where petitioner has clearly shown that the public respondent acted without jurisdiction or with grave abuse of discretion amounting to lack or excess of jurisdiction. However, and more serious than the procedural infraction, if the petition merely calls for an ordinary review of the findings of the court a quo, we would run afoul of the constitutional right against double jeopardy. Such recourse is tantamount to converting the petition for certiorari into an appeal, which is proscribed by the Constitution, the Rules of Court and prevailing jurisprudence on double jeopardy.[28]Verdicts of acquittal are to be regarded as absolutely final and irreviewable. The fundamental philosophy behind the principle is to afford the defendant, who has been acquitted, final repose and to safeguard him from government oppression through the abuse of criminal processes.[29]
This Court cannot rule any other way. Accused Joseph Terrado, after being acquitted of the crime charged, must be afforded the protection against repeated attempts for conviction, in faithful adherence to the constitutional rule against double jeopardy.
