At the outset, we should observe that the petitioner has adopted the wrong remedy in assailing the CA’s affirmance of his conviction. His proper recourse from the affirmance of his conviction was an appeal taken in due course. Hence, he should have filed a petition for review on certiorari. Instead, he wrongly brought a petition for certiorari. We explained why in People v. Court of Appeals:12
The special civil action for certiorari is intended for the correction of errors of jurisdiction only or grave abuse of discretion amounting to lack or excess of jurisdiction. Its principal office is only to keep the inferior court within the parameters of its jurisdiction or to prevent it from committing such a grave abuse of discretion amounting to lack or excess of jurisdiction. As observed in Land Bank of the Philippines v. Court of Appeals, et al. “the special civil action for certiorari is a remedy designed for the correction of errors of jurisdiction and not errors of judgment. The raison d’etre for the rule is when a court exercises its jurisdiction, an error committed while so engaged does not deprived it of the jurisdiction being exercised when the error is committed. If it did, every error committed by a court would deprive it of its jurisdiction and every erroneous judgment would be a void judgment. In such a scenario, the administration of justice would not survive. Hence, where the issue or question involved affects the
wisdom or legal soundness of the decision–not the jurisdiction of the court to render said decision–the same is beyond the province of a special civil action for certiorari. The proper recourse of the aggrieved party from a decision of the Court of Appeals is a petition for review on certiorari under Rule 45 of the Revised Rules of Court.
