A motion to quash is the accused's formal, written challenge to a criminal complaint or information, filed at any time before entering a plea, asking the court to dismiss the case on one of nine specific grounds listed in Rule 117 of the Rules of Court — such as the facts charged not constituting an offense, lack of jurisdiction, or a prior conviction or acquittal for the same offense. It is a pre-trial remedy aimed at the sufficiency of the charge itself, not a trial on guilt or innocence.
Timing: Before Plea, or the Right Is Generally Waived
Section 1 of Rule 117 is unambiguous: the accused may move to quash the complaint or information at any time before entering his plea. Filing after arraignment generally waives most of the available grounds — which is exactly why the motion is treated as a threshold, pre-trial device rather than something raised mid-trial. The motion must be in writing, signed by the accused or counsel, and must distinctly specify its factual and legal grounds — under Section 2, the court will consider no ground other than those actually stated in the motion, except lack of jurisdiction over the offense, which the court may always take up on its own.
The Nine Grounds Under Section 3
- That the facts charged do not constitute an offense;
- That the court has no jurisdiction over the offense charged;
- That the court has no jurisdiction over the person of the accused;
- That the officer who filed the information had no authority to do so;
- That the complaint or information does not conform substantially to the prescribed form;
- That more than one offense is charged, except where a single penalty for various offenses is allowed by law;
- That the criminal action or liability has been extinguished;
- That it contains averments which, if true, would constitute a legal excuse or justification; and
- That the accused has been previously convicted or acquitted of the offense charged, or the case was dismissed or otherwise terminated without express consent.
A Curable Defect Gets a Chance to Be Fixed First
Not every quashal ends the case outright. Under Section 4, if the motion is based on a defect that can be cured by amendment, the court orders the amendment instead of dismissing outright. If the ground is specifically that the facts charged do not constitute an offense, the prosecution is given the opportunity to correct the defect by amendment — the motion is granted only if the prosecution fails to amend, or the amended pleading still suffers the same defect. This built-in cure step means a motion to quash based on a drafting deficiency often results in a corrected information rather than outright dismissal.
What Happens When the Motion Is Granted
Under Section 5, if the motion is sustained, the court may order that another complaint or information be filed, except where refiling is barred (see below). If such an order is made, an accused who is in custody is not discharged unless separately admitted to bail. If no such order is made — or one is made but no new information is filed within the time allowed — the accused, if in custody, is discharged, unless held for another charge. Critically, under Section 6, sustaining a motion to quash is generally not a bar to another prosecution for the same offense, except where the ground was extinguishment of criminal liability or prior conviction/acquittal/dismissal without consent — those two grounds carry double jeopardy consequences that block refiling.
How This Differs From an Acquittal on the Merits
A motion to quash attacks the complaint or information itself, or the court's authority to proceed — it does not require the prosecution to present evidence of guilt, and in most cases a successful motion simply reopens the door to a properly filed case. An acquittal, by contrast, comes only after arraignment and a trial on the merits, and triggers double jeopardy under Section 7, barring another prosecution for the same offense (or one necessarily included in it), subject to narrow exceptions such as a graver offense that only became known after the plea. Understanding this distinction matters because a motion to quash granted on most grounds leaves the prosecution free to refile a corrected charge, while a genuine acquittal generally does not.
Practical Takeaways
- A motion to quash must be filed before entering a plea — the accused generally waives most grounds by pleading first;
- It must be in writing and distinctly state its grounds — the court considers only what is raised, except lack of jurisdiction over the offense;
- A curable defect (like a poorly drafted information) generally gives the prosecution a chance to amend rather than ending the case;
- Most grounds, if sustained, do not bar refiling — only extinguished liability and prior conviction/acquittal/dismissal-without-consent carry that double jeopardy effect.
Frequently Asked Questions
When must a motion to quash be filed? At any time before the accused enters a plea. Filing after arraignment generally waives most of the available grounds under Rule 117.
What are the grounds for a motion to quash? Rule 117, Section 3 lists nine grounds, including that the facts charged do not constitute an offense, lack of jurisdiction over the offense or the person of the accused, lack of authority of the filing officer, duplicity of offenses charged, extinguishment of criminal liability, and prior conviction, acquittal, or dismissal without consent for the same offense.
If my motion to quash is granted, is the case over for good? Not usually. The court may order that a new complaint or information be filed, and sustaining the motion is generally not a bar to another prosecution — except where the ground was extinguishment of criminal liability or a prior conviction, acquittal, or dismissal without the accused's consent.
Is a motion to quash the same as an acquittal? No. It challenges the complaint or information itself, usually before trial, and does not require the prosecution to prove guilt. An acquittal comes only after arraignment and a trial on the merits and triggers double jeopardy, which generally bars refiling altogether.
