A careful reading of the questioned Resolution reveals that the Ombudsman dismissed petitioner's criminal complaint because respondents had validly resorted to the police power of the State when they effected the demolition of the illegal fishpond in question following the declaration thereof as a nuisance per se. Thus, the Ombudsman was of the opinion that no violation of Section 3(e)21 of the Anti-Graft and Corrupt Practices Act or of Article 32422 of the Revised Penal Code was committed by respondents. In the words of the Ombudsman, "those who participated in the blasting of the subject fishpond were only impelled by their desire to serve the best interest of the general public; for the good and the highest good."23
By grave abuse of discretion is meant capricious and whimsical exercise of judgment as is equivalent to lack of jurisdiction. Mere abuse of discretion is not enough. It must be grave abuse of discretion as when the power is exercised in an arbitrary or despotic manner by reason of passion or personal hostility, and must be so patent and so gross as to amount to an evasion of a positive duty or to a virtual refusal to perform the duty enjoined or to act at all in contemplation of law.24
Grave abuse of discretion should be differentiated from an error in judgment. An error of judgment is one which the court may commit in the exercise of its jurisdiction, and which error is reversible only by an appeal. As long as the court acts within its jurisdiction, any alleged errors committed in the exercise of its discretion will amount to nothing more than mere errors of judgment, correctible by an appeal or a petition for review under Rule 45 of the Rules of Court. An error of jurisdiction is one where the act complained of was issued by the court without or in excess of jurisdiction and which error is correctible only by the extraordinary writ of certiorari.25
The other errors raised by petitioner pertain to the Ombudsman's opinion on the lack of probable cause to indict respondents. These are purported errors in judgment which can be corrected by an appeal, although not via a direct appeal to this Court. Direct resort to this Court may be had only through the extraordinary writ of certiorari and upon showing that the Ombudsman committed grave abuse of discretion, which petitioner failed to demonstrate.
Absent any grave abuse of discretion tainting it, the courts will not interfere with the Ombudsman's supervision and control over the preliminary investigation conducted by him.26 It is beyond the ambit of this Court to review the exercise of discretion of the Ombudsman in prosecuting or dismissing a complaint filed before it.27 The rule is based not only upon respect for the investigatory and prosecutory powers granted by the Constitution to the Office of the Ombudsman but upon practicality as well. Otherwise, the functions of the courts will be grievously hampered by innumerable petitions assailing the dismissal of investigatory proceedings conducted by the Office of the Ombudsman with regard to complaints filed before it, in much the same way that the courts would be extremely swamped if they would be compelled to review the exercise of discretion on the part of the fiscals or prosecuting attorneys each time they decide to file an information in court or dismiss a complaint by a private complainant.28
