Villaflor vs. Vivar

The absence of a preliminary investigation does not invalidate an information, affect the court's jurisdiction, or serve as a ground for quashing the information; rather than dismissing the case, the court should suspend proceedings and order the prosecutor to conduct a preliminary investigation.

• On February 7, 1997, an Information for slight physical injuries was filed against respondent Dindo Vivar before the Metropolitan Trial Court (MTC) of Muntinlupa City, docketed as Criminal Case No. 23365, arising from the alleged mauling of petitioner Gian Paulo Villaflor outside the Fat Tuesday Bar at Ayala Alabang Town Center on January 27, 1997.
• During the incident, respondent allegedly uttered the threatening words "Sa susunod gagamitin ko na itong baril ko" ("Next time, I will use my gun on you").
• When the injuries sustained by petitioner turned out to be more serious than initially assessed, an Information for serious physical injuries was filed (Criminal Case No. 23787) and the original charge for slight physical injuries was withdrawn.
• On March 17, 1997, another Information for grave threats (Criminal Case No. 23728) was filed against respondent based on the alleged threatening utterance.
• On April 14, 1997, respondent posted a cash bond of P6,000 in the serious physical injuries case.
• On April 21, 1997, respondent filed a Motion to Quash the Information in the grave threats case, arguing that the threat should have been absorbed by the serious physical injuries charge and that the court therefore lacked jurisdiction.
• The MTC denied the Motion to Quash on April 28, 1997, ruling that it was a prohibited pleading under the Rules on Summary Procedure, and subsequently denied the Motion for Reconsideration on June 17, 1997.
• Respondent was arraigned in the grave threats case and pleaded not guilty.
• On July 18, 1997, respondent filed a Petition for Certiorari with the Regional Trial Court (RTC) of Muntinlupa City (Civil Case No. 97-134), assailing the MTC orders.
• On January 20, 1998, the RTC granted the Motion to Quash and ordered the dismissal of the criminal cases, ruling that the Informations were filed without preliminary investigation.
• On July 6, 1998, the RTC denied the Motion for Reconsideration, citing Section 51 paragraph 3(a) of Republic Act No. 7926 (the Muntinlupa City Charter), which requires the city prosecutor to conduct preliminary investigations of all crimes.

• The trial court cannot motu proprio order the dismissal of criminal cases on the ground that the public prosecutor failed to conduct a preliminary investigation.
• The failure to conduct a preliminary investigation is not a ground to quash the criminal informations under Section 3, Rule 117 of the Revised Rules of Criminal Procedure.
• The respondent's entry of plea in the grave threats case and posting of cash bond in the serious physical injuries case constitute a waiver of his right to preliminary investigation.
• The amendment from slight to serious physical injuries was merely formal and did not require a new preliminary investigation because it charged essentially the same offense and could not have surprised the accused.

• The threat alleged in the grave threats case should have been absorbed by the charge of serious physical injuries, thus the trial court did not acquire jurisdiction over the grave threats case.
• The Motion to Quash should have been treated under the regular rules of procedure rather than the Rules on Summary Procedure, and the MTC committed grave abuse of discretion in declaring it a prohibited pleading.
• The criminal charges were filed without preliminary investigation as required by Section 51 paragraph 3(a) of Republic Act No. 7926, which mandates the city prosecutor to conduct preliminary investigations of all crimes, thereby amending the Rules on Criminal Procedure and requiring dismissal of the cases.

• Procedural: Whether the Regional Trial Court gravely abused its discretion in granting the Motion to Quash and ordering the dismissal of the criminal cases on the ground of lack of preliminary investigation.
• Substantive Issues:
  • Whether the absence of a preliminary investigation constitutes a ground for quashing an information or affects the validity of the information and the jurisdiction of the court.
  • Whether the amendment from slight to serious physical injuries required a new preliminary investigation.
  • Whether the respondent waived his right to preliminary investigation by posting bail and entering a plea of not guilty.

• Procedural: The Supreme Court held that the RTC committed grave abuse of discretion in granting the Motion to Quash and dismissing the criminal cases. The absence of a preliminary investigation does not impair the validity of the information or render it defective, neither does it affect the jurisdiction of the court or constitute a ground for quashing the information. Instead of dismissal, the court should hold proceedings in abeyance and order the public prosecutor to conduct a preliminary investigation.
• Substantive: The Court ruled that lack of preliminary investigation is not among the grounds for a motion to quash under Section 3, Rule 117 of the Revised Rules of Criminal Procedure. Furthermore, a motion to quash is a prohibited pleading under Section 19 of the Revised Rules on Summary Procedure. The amendment from slight to serious physical injuries was merely formal because it did not charge a different or distinct offense, and the amended information could not have surprised the accused since it charged essentially the same offense; therefore, no new preliminary investigation was required. The respondent waived his right to file a motion to quash when he pleaded not guilty to the charge of grave threats, as failure to assert grounds for a motion to quash before arraignment constitutes a waiver under Section 9, Rule 117 of the Revised Rules of Criminal Procedure.

• Preliminary Investigation as a Component of Due Process — Defined as an inquiry to determine whether there is sufficient ground to engender a well-founded belief that a crime has been committed and the respondent is probably guilty thereof. It is a statutory and substantive right accorded to the accused before trial, but its absence does not invalidate the information or affect jurisdiction.
• Effect of Lack of Preliminary Investigation — The absence of preliminary investigation does not impair the validity of an information, render it defective, affect the jurisdiction of the court, or constitute a ground for quashing the information. The proper remedy is to hold proceedings in abeyance and order the prosecutor to conduct the investigation rather than dismiss the case.
• Formal Amendment to Information — An amendment that does not charge another offense different or distinct from that charged in the original one, or that does not alter the prosecution's theory of the case so as to cause surprise to the accused, is merely formal and does not require a new preliminary investigation.
• Waiver of Right to File Motion to Quash — The failure of the accused to assert any ground for a motion to quash before arraignment, either because he had not filed the motion or had failed to allege the grounds therefor, shall be deemed a waiver of such grounds, except for grounds relating to no offense charged, lack of jurisdiction over the offense charged, extinction of the offense or penalty, and jeopardy.

• "The absence of a preliminary investigation does not impair the validity of an information or render it defective. Neither does it affect the jurisdiction of the court or constitute a ground for quashing the information. Instead of dismissing the information, the court should hold the proceedings in abeyance and order the public prosecutor to conduct a preliminary investigation."
• "Preliminary investigation is a statutory and substantive right accorded to the accused before trial. To deny their claim to a preliminary investigation would be to deprive them of the full measure of their right to due process."

• Go v. Court of Appeals — Cited for the principle that preliminary investigation is a component part of due process in criminal justice and a statutory right.
• People v. Deang — Cited as controlling precedent that the absence of preliminary investigation does not impair the validity of the information or constitute a ground for quashing.
• People v. Gomez — Cited alongside People v. Deang regarding the effect of lack of preliminary investigation on the validity of information.
• People v. Casiano — Cited alongside People v. Deang regarding the effect of lack of preliminary investigation on jurisdiction.
• Paredes v. Sandiganbayan — Cited for the rule that instead of dismissing the information, the court should hold proceedings in abeyance and order the prosecutor to conduct preliminary investigation.
• Sanciangco Jr. v. People — Cited for the same rule regarding holding proceedings in abeyance pending preliminary investigation.
• Teehankee Jr. v. Madayag — Cited for the definition of formal amendments to informations that do not require new preliminary investigations.

• Section 1, Rule 112 of the Revised Rules of Criminal Procedure — Defines preliminary investigation as an inquiry to determine whether there is sufficient ground to engender a well-founded belief that a crime has been committed and the respondent is probably guilty thereof.
• Section 3, Rule 117 of the Revised Rules of Criminal Procedure — Enumerates the exclusive grounds for a motion to quash, which does not include lack of preliminary investigation.
• Section 9, Rule 117 of the Revised Rules of Criminal Procedure — Provides that failure to assert grounds for motion to quash before arraignment constitutes a waiver, except for specific grounds relating to jurisdiction, extinction of offense, and jeopardy.
• Section 19 of the Revised Rules on Summary Procedure — States that a motion to quash is a prohibited pleading in cases governed by summary procedure.
• Section 51, paragraph 3(a) of Republic Act No. 7926 (The Muntinlupa City Charter) — Provides that the city prosecutor shall conduct preliminary investigations of all crimes, which the RTC erroneously interpreted as requiring dismissal for non-compliance rather than simply ordering the conduct of the investigation.
