Magno vs. People of the Philippines

The Sandiganbayan exercises exclusive appellate jurisdiction over petitions for certiorari assailing interlocutory orders of the regional trial court in criminal cases involving public officers charged in relation to their office.

Public officers of the National Bureau of Investigation were charged with multiple frustrated murder and double attempted murder. At the arraignment, petitioner objected to the formal appearance of a private prosecutor acting on behalf of the Office of the Ombudsman, invoking the limitations of Republic Act No. 6770. The regional trial court sustained the objection and excluded the private prosecutor from acting on the Ombudsman's behalf.

• The Information: On May 14, 2003, the Office of the Ombudsman filed an information for multiple frustrated murder and double attempted murder against several accused, including petitioner Angelito P. Magno, who were public officers working under the National Bureau of Investigation.
• Objection to Private Prosecutor: During the scheduled arraignment, Magno orally objected to the appearance and authority of Atty. Adelino B. Sitoy as private prosecutor prosecuting the case on behalf of the Office of the Ombudsman. The oral objection was reduced to writing on July 21, 2003, citing Section 31 of Republic Act No. 6770.
• RTC Order: On September 25, 2003, the RTC issued an Order ruling that the Ombudsman is the proper, legal, and authorized entity to prosecute the case to the exclusion of any other entity or person not authorized under R.A. 6770. The RTC denied the Ombudsman's motion for reconsideration on October 1, 2003.
• CA Proceedings: Respondents filed a petition for certiorari before the CA. The CA initially ruled that the private prosecutor could appear only for the civil aspect of the case. On motion for reconsideration, the CA amended its decision on September 26, 2005, allowing the private prosecutor to intervene in the prosecution of the offense charged in collaboration with any lawyer deputized by the Ombudsman.

• Jurisdiction of the Court of Appeals: Petitioner argued that the CA lacked jurisdiction to entertain the petition for certiorari, asserting that the Sandiganbayan has the exclusive power to issue such petitions in aid of its appellate jurisdiction over the RTC.
• Deputization of Private Practitioners: Petitioner maintained that Section 31 of R.A. 6770 limits the Ombudsman's prerogative to designate fiscals, state prosecutors, and government lawyers, and does not authorize the deputization of private practitioners to prosecute cases on behalf of the Office of the Ombudsman.

• Intervention under the Rules of Court: Respondents countered that the private prosecutor may intervene pursuant to Section 16, Rule 110 of the Rules of Court, which allows the offended party to intervene by counsel in the prosecution of the offense.
• Harmonious Construction of Laws: Respondents argued that Section 31 of R.A. 6770 did not amend Section 16, Rule 110 of the Rules of Court, claiming that a private prosecutor may appear for the private offended complainants independent of the Ombudsman's exclusive right to deputize.

• Jurisdiction: Whether the Court of Appeals had jurisdiction to entertain the petition for certiorari challenging the RTC's interlocutory order in a criminal case involving public officers.
• Deputization of Private Prosecutors: Whether the Ombudsman may deputize private practitioners to prosecute cases on its behalf under Section 31 of R.A. 6770.

• Jurisdiction: The Court of Appeals lacked jurisdiction. Under Section 4 of Presidential Decree No. 1606, the Sandiganbayan exercises exclusive appellate jurisdiction over final judgments, resolutions, or orders of regional trial courts in cases involving public officers. This exclusive appellate jurisdiction includes the power to issue writs of certiorari in aid of such jurisdiction. Because the accused were public officers charged with crimes in relation to their office, the petition for certiorari assailing the RTC order should have been filed with the Sandiganbayan. The CA's amended decision was declared null and void for having been issued without jurisdiction.
• Deputization of Private Prosecutors: This issue was not reached. The jurisdictional defect rendered the CA's decision void, precluding the necessity to resolve the substantive issue regarding the Ombudsman's authority to deputize private prosecutors.

• Jurisdiction Conferred by Law; Void Judgments Jurisdiction over the subject matter is conferred by law and cannot be determined by the parties' action or conduct. Estoppel generally does not confer jurisdiction where none exists by law. Any judgment, order, or resolution issued without jurisdiction is void and cannot be given any effect. Lack of jurisdiction over the subject matter may be raised at any time, even on appeal or after final judgment. The Court applied this doctrine to nullify the CA's amended decision, which was issued without jurisdiction, notwithstanding that the issue was raised in a supplemental motion for reconsideration before the CA.
• Estoppel on the Question of Jurisdiction The operation of estoppel on jurisdiction depends on whether the lower court actually had jurisdiction. If the court had no jurisdiction but the case was tried on the theory that it had, the parties are not barred on appeal from assailing such jurisdiction. If the court had jurisdiction but the case was tried on the theory that it did not, the party who induced that theory is estopped from assuming an inconsistent position on appeal. The Court applied this principle to reject the Ombudsman's reliance on estoppel, as the CA never possessed jurisdiction over the subject matter.

• "Jurisdiction over a subject matter is conferred by law and not by the parties’ action or conduct. Estoppel generally does not confer jurisdiction over a cause of action to a tribunal where none, by law, exists."
• "Whenever it appears that the court has no jurisdiction over the subject matter, the action shall be dismissed. This defense may be interposed at any time, during appeal or even after final judgment."

• Abbot v. Mapayo, G.R. No. 134102 (July 6, 2000) Controlling precedent. Held that the Sandiganbayan has the exclusive power to issue petitions for certiorari in aid of its appellate jurisdiction over RTCs handling cases involving public officials, thereby divesting the CA of jurisdiction.
• Machado v. Gatdula, G.R. No. 156287 (February 16, 2010) Followed. Reiterated the principle that jurisdiction is conferred by law and lack thereof can be raised at any time, and that estoppel does not confer jurisdiction.
• People v. Casiano, L-15309 (February 16, 1961) Followed. Clarified the application of estoppel to questions of jurisdiction, holding that parties are not estopped from assailing a court's jurisdiction on appeal if the court never actually possessed it.

• Section 4, Presidential Decree No. 1606 Defines the jurisdiction of the Sandiganbayan. Applied to establish that the Sandiganbayan exercises exclusive appellate jurisdiction over RTC orders in cases involving public officers, including exclusive original jurisdiction over petitions for certiorari in aid of its appellate jurisdiction.
• Section 31, Republic Act No. 6770 Authorizes the Ombudsman to utilize office personnel or deputize fiscals, state prosecutors, or government lawyers as special investigators or prosecutors. Cited by petitioner to argue against the deputization of private practitioners, though not definitively resolved by the Court.
• Section 16, Rule 110, Rules of Court Allows the offended party to intervene by counsel in the prosecution of the offense. Cited by respondents to justify the private prosecutor's appearance, though not definitively resolved by the Court.
