A motion to dismiss can end your case entirely before trial — no jury, no verdict, no conviction. But it only works when specific legal grounds exist. Here's what those grounds are, how to write the motion, and what realistic expectations look like.
A motion to dismiss asks the court to throw out the charges against you entirely, before trial begins. If granted, the case ends — you are not tried, not convicted, and the charges are gone. That's the best possible pretrial outcome.
But motions to dismiss in criminal cases only succeed on narrow, specific grounds. Unlike in civil litigation, where motions to dismiss for failure to state a claim are routine, criminal charges survive pretrial motion practice in the vast majority of cases. Courts apply a low threshold: if the indictment or information alleges facts that, if true, would constitute the crime charged, dismissal is not appropriate.
This doesn't mean you shouldn't file one. It means you need to identify a specific, recognized ground before you file — not a general argument that you're innocent or that the evidence is weak. Courts dismiss cases on legal grounds, not factual ones, at the pretrial stage. Factual disputes go to the jury.
The Sixth Amendment guarantees the right to a speedy trial. The federal Speedy Trial Act requires that federal defendants be tried within 70 days of indictment. Most states have analogous statutes with specific time limits. If the prosecution fails to bring your case to trial within the statutory period — and the delay is not attributable to defense requests for continuances — dismissal is the remedy.
What you need: Calculate the time from indictment or arraignment to your current date. Identify continuances that were granted at your request (those days are excluded). Check whether the total non-excluded delay exceeds the statutory limit. File the motion immediately when you identify a violation — courts can find waiver if you wait.
The Fifth Amendment bars being tried twice for the same offense. If you were previously acquitted or convicted of the same charge, or if jeopardy attached in a prior proceeding that was dismissed on the merits, a subsequent prosecution is barred. Double jeopardy also covers lesser included offenses — you generally cannot be prosecuted for a lesser offense after acquittal of a greater one that subsumes it.
What you need: Evidence of the prior proceeding — the charging document, the verdict or order of dismissal, and the docket showing jeopardy attached. The motion must identify the earlier case, the charges, and why the current charges constitute the same offense under the Blockburger test.
Criminal charges must be filed within the statute of limitations for the offense — typically three to five years for most felonies, one to two years for misdemeanors, with longer periods for serious offenses like murder. If the indictment or information was filed after the limitations period expired, the case must be dismissed.
What you need: The date of the alleged offense, the applicable statute of limitations under your state's code, and the filing date of the charges. If the charge was filed outside the window, the motion is straightforward — cite the statute, show the dates, move for dismissal.
An indictment or information must allege all elements of the offense with sufficient specificity to notify the defendant of the charge and to prevent re-prosecution for the same conduct. If the charging document fails to allege an essential element of the offense, or is so vague that you cannot prepare a defense, dismissal may be warranted. Courts can also order the prosecution to provide a bill of particulars if the charging document is too vague.
What you need: Compare the elements of the charged offense (from the statute) to what the charging document actually alleges. If an element is missing or the allegations are incomprehensibly vague, move to dismiss. Courts often dismiss without prejudice on this ground, allowing the prosecution to re-file with a corrected charging document — but that costs them time and may cause Brady material to surface.
When government agents engaged in conduct so outrageous that prosecution would violate due process, courts have dismissed cases under the due process clause. This is a very high standard — courts have sustained it in cases where the government itself manufactured the crime, provided all the means and opportunity, and targeted a defendant who had no predisposition to commit the offense. Entrapment is normally a trial defense, but outrageous government conduct can support pretrial dismissal.
What you need: Specific documented facts showing the government's role in creating or instigating the offense, the lack of predisposition on your part, and why the conduct shocks the conscience. This ground rarely succeeds — courts are reluctant to dismiss cases on it — but in extreme factual situations it is a viable argument.
Serious prosecutorial misconduct — presenting false evidence to a grand jury, knowingly eliciting perjured testimony, suppressing Brady material — can support a motion to dismiss, particularly if the misconduct infected the charging decision itself. Dismissal for prosecutorial misconduct is a severe remedy courts reserve for egregious cases, but it is recognized as a ground when the conduct was willful and prejudiced the defendant's ability to get a fair trial.
What you need: Concrete, documented evidence of the misconduct — not an allegation, but actual proof. Discovery materials, grand jury transcripts (where obtainable), prior judicial findings, or documented Brady violations. Courts do not dismiss based on accusations alone.
Pro se defendants frequently file motions to dismiss on grounds that courts consistently reject. Filing these wastes your time and credibility:
A motion to dismiss follows the same basic structure as other criminal motions. Keep it concise and legally precise:
Use Brief to evaluate the ground before you file. Filing a motion to dismiss on a weak or legally unsound theory does more harm than good — it signals to the court that you don't understand the law, and it locks in a record that can be used against you. Upload your charging documents and case timeline to Brief to understand whether you have a viable dismissal ground before you write a word of the motion.
Upload your charging documents and case timeline. Brief checks your case against the recognized grounds for dismissal — speedy trial calculations, limitations periods, charging document defects — and tells you what's worth filing before you invest time in a motion that won't succeed.
