When Is There Grave Abuse On The Part of the Office of the Ombudsman?

There is grave abuse of discretion on the part of the Office of the Ombudsman when it acts in a capricious, whimsical, arbitrary or despotic manner in the exercise of its judgment amounting to lack of jurisdiction. Mere abuse of discretion is not enough. The only question involved is jurisdiction, either the lack or excess thereof, and abuse of discretion warrants the issuance of the extraordinary remedy of certiorari only when the same is grave, as when the power is exercised in an arbitrary or despotic manner by reason of passion, prejudice or personal hostility. A writ of certiorari is a remedy designed for the correction of errors of jurisdiction and not errors of judgment. An error of judgment is one in which the court may commit in the exercise of its jurisdiction, and which error is reversible only by an appeal. (Rep. v. Francisco, et al., G.R. No. 163089, December 7, 2007).
