To get a federal indictment dismissed, you file a pretrial motion to dismiss that identifies a specific legal defect in how the charges were brought—not an argument that you didn’t do it, but an argument that the process itself was flawed enough to invalidate the indictment. The grounds that actually work fall into a short list: errors in the grand jury, prosecutorial misconduct, a defective indictment, a speedy trial violation, an expired statute of limitations, or prejudicial pre-indictment delay. Judges grant these motions less often than defendants hope, and timing rules are strict. Miss the pretrial deadline and most objections are waived.
Grand Jury Errors
A federal grand jury must have between 16 and 23 members, and either side can challenge a grand jury that wasn’t properly drawn, summoned, or selected.1Legal Information Institute. Federal Rules of Criminal Procedure Rule 6 – The Grand Jury If membership fell below the required number, or individual jurors were not legally qualified, the indictment they returned can be attacked.
Secrecy rules are enforced strictly. During testimony, only government attorneys, the witness, interpreters, and a court reporter may be present. During deliberations and voting, only jurors themselves (plus any interpreter assisting a hearing-impaired juror) may remain.1Legal Information Institute. Federal Rules of Criminal Procedure Rule 6 – The Grand Jury An unauthorized person in the room is a concrete basis for a motion.
Prosecutorial Misconduct
No judge or defense attorney watches over the prosecutor in the grand jury room, so the misconduct rules matter. Knowingly presenting false testimony is the clearest violation. The Supreme Court has long recognized that using perjured evidence violates basic fairness, and grand jury proceedings are no exception.2Legal Information Institute. United States v. Williams, 504 US 36 (1992) – Dissent Inflammatory statements unsupported by evidence, misstating facts during witness questioning, or fabricating statements attributed to witnesses can also justify dismissal.
Selective and Vindictive Prosecution
Both can be raised by pretrial motion under Federal Rule of Criminal Procedure 12.3Legal Information Institute. Federal Rules of Criminal Procedure Rule 12 – Pleadings and Pretrial Motions
Selective prosecution means the government singled you out based on an impermissible factor such as race, religion, or political affiliation. The defense generally must show both a discriminatory effect (similarly situated people of a different group were not charged) and discriminatory intent. Even getting discovery on this claim is difficult; courts set the bar very high.
Vindictive prosecution means the government escalated or brought charges to punish you for exercising a legal right, like going to trial instead of pleading, or successfully appealing a prior conviction. You can try to show direct evidence of retaliatory motive, or argue that the circumstances create a reasonable likelihood of vindictiveness. If you establish that appearance, the burden shifts to the prosecution to prove the charges were independently justified.
Defects in the Indictment Itself
Sometimes the problem is what’s on the paper. An indictment can be dismissed if it fails to state an offense—if the conduct described, even taken as entirely true, wouldn’t actually be a crime under the charged statute. It can also be attacked for lack of specificity (not enough detail to prepare a defense), charging the same offense in more than one count, or improperly joining unrelated offenses.3Legal Information Institute. Federal Rules of Criminal Procedure Rule 12 – Pleadings and Pretrial Motions Most of these must be raised before trial, but failure to state an offense and lack of jurisdiction can be raised at any stage, even after conviction.
Speedy Trial Violations
The federal Speedy Trial Act sets hard statutory deadlines. An indictment must be filed within 30 days of arrest or service of a summons. Once indicted, trial must begin within 70 days of the indictment or the defendant’s first court appearance, whichever comes later.4Office of the Law Revision Counsel. 18 USC Ch. 208 – Speedy Trial Various periods are excluded from the clock—continuances for good cause, time on pretrial motions, competency evaluations—but the core deadlines are firm.
Miss the 30-day mark and the complaint must be dismissed. Miss the 70-day mark and the defendant can move to dismiss the indictment. In deciding whether the dismissal is with or without prejudice, the court weighs the seriousness of the offense, the circumstances of the delay, and the impact of allowing a refiling.5Office of the Law Revision Counsel. 18 USC 3162 – Sanctions This is one of the more concrete grounds because the deadline is statutory and the remedy is mandatory. The only real question is whether the government gets a second chance.
One trap: the right to dismissal on speedy trial grounds must be raised before trial or before entering a guilty plea. Failing to raise it waives it entirely.5Office of the Law Revision Counsel. 18 USC 3162 – Sanctions
Expired Statute of Limitations
Most federal crimes carry a five-year statute of limitations, meaning the indictment must be returned within five years of the offense.6Office of the Law Revision Counsel. 18 USC 3282 – Offenses Not Capital Exceptions exist for specific categories—terrorism, tax fraud, certain financial offenses, and capital crimes have longer or no limitations periods. For a standard federal felony, if the five-year window has closed, the defense can move to dismiss.
This is an affirmative defense. The court will not dismiss on this basis on its own, and a limitations defense not raised at or before trial can be permanently lost.
Pre-Indictment Delay
Even when the statute of limitations hasn’t expired, an unusually long delay between the alleged offense and the indictment can violate due process. The defense must show two things: real prejudice from the delay (lost witnesses, faded memories, destroyed evidence) and that the government delayed intentionally or through deliberate indifference to gain a tactical advantage. Delay alone is not enough. Federal Rule 12 lists pre-indictment delay as a ground that must be raised by pretrial motion.3Legal Information Institute. Federal Rules of Criminal Procedure Rule 12 – Pleadings and Pretrial Motions
Grounds That Sound Strong But Usually Don’t Work
Three arguments come up constantly in defendants’ minds and rarely work in court. Knowing this before drafting a motion saves time.
Insufficient Evidence Before the Grand Jury
In Costello v. United States (1956), the Supreme Court held that courts will not examine the adequacy or competency of the evidence behind an indictment. If the grand jury was legally constituted and the indictment is valid on its face, the Fifth Amendment requires nothing more.7Justia Law. Costello v. United States, 350 US 359 (1956) Narrow exceptions exist when the government presented literally no evidence on an essential element, or when the evidence was so fundamentally flawed no rational grand jury could have found probable cause, but the presumption runs heavily in favor of the indictment.
Illegally Obtained Evidence
Many defendants assume that if police conducted an illegal search or took a statement without proper Miranda warnings, the indictment must fall. That is generally not how it works. In United States v. Calandra (1974), the Supreme Court held that a grand jury witness cannot refuse to answer questions simply because they stem from an unlawful search, and that an indictment valid on its face cannot be challenged based on the character of the evidence the grand jury considered.8Legal Information Institute. United States v. Calandra, 414 US 338 (1974) The remedy for unconstitutional evidence-gathering usually comes at trial through a motion to suppress, which can gut the prosecution’s case, but it doesn’t invalidate the indictment.9Constitution Annotated. Amdt4.7.1 Exclusionary Rule and Evidence
Withheld Exculpatory Evidence
The Department of Justice has an internal policy requiring federal prosecutors to disclose substantial evidence that directly negates a suspect’s guilt before seeking an indictment. The policy itself says a failure to follow it “should not result in dismissal of an indictment.”10United States Department of Justice. Justice Manual 9-11.000 – Grand Jury In United States v. Williams (1992), the Supreme Court held that federal courts have no authority to require prosecutors to present exculpatory evidence to a grand jury and cannot dismiss indictments on that basis.11Legal Information Institute. United States v. Williams, 504 US 36 (1992) A policy violation may trigger internal professional responsibility review, but on its own it won’t get the indictment thrown out.
How to File the Motion
The formal vehicle is a motion to dismiss filed in the district court where the case is pending. Federal Rule 12 replaced older devices like demurrers and pleas in abatement with this single, unified motion.3Legal Information Institute. Federal Rules of Criminal Procedure Rule 12 – Pleadings and Pretrial Motions The motion identifies the legal ground, lays out the supporting facts, and argues why the indictment cannot stand. It typically includes analysis of any available grand jury transcripts, the governing law, and supporting evidence such as sworn statements. For a speedy trial claim, the motion walks through the timeline of arrest, indictment, and every stretch of excludable delay. For a grand jury misconduct claim, it identifies the unauthorized person present or the false testimony offered.
Timing is critical. Most grounds—grand jury errors, prosecutorial misconduct, speedy trial violations, defects in the indictment’s wording, selective and vindictive prosecution, pre-indictment delay—must be raised before trial if the basis is reasonably available then. The court sets a specific deadline for pretrial motions, and missing it can waive the objection. A late motion is considered only on a showing of good cause.3Legal Information Institute. Federal Rules of Criminal Procedure Rule 12 – Pleadings and Pretrial Motions The two exceptions preserved at any point are lack of jurisdiction and failure to state an offense.
What Happens at the Hearing
The prosecution files a written response, and the court typically holds a hearing where both sides argue directly to the judge. No jury is involved. The defense generally carries the burden of showing a legal basis for dismissal, though for certain grounds like a speedy trial violation, the government has to prove that excludable time justifies the delay.
If the judge denies the motion, the case moves toward trial or plea negotiations. That denial usually isn’t immediately appealable. The defendant must wait until after trial and raise the issue on appeal from a conviction, and if there’s an acquittal the point becomes moot.
Dismissal With or Without Prejudice
If the motion is granted, the type of dismissal decides whether the government can come back.
A dismissal without prejudice ends the current case but lets the government try again. This typically follows a correctable problem—an improperly composed grand jury, a technical defect in the indictment’s language, or a curable procedural error. The court may order release or continued detention for a set period while the government decides whether to seek a new indictment.3Legal Information Institute. Federal Rules of Criminal Procedure Rule 12 – Pleadings and Pretrial Motions
A dismissal with prejudice permanently bars the government from refiling the same charges. Judges reserve it for the worst problems: egregious prosecutorial misconduct, constitutional violations that cannot be cured, or situations where re-prosecution would be fundamentally unfair. For speedy trial violations specifically, the court weighs seriousness of the offense, reasons for the delay, and impact on the administration of justice.5Office of the Law Revision Counsel. 18 USC 3162 – Sanctions
If the Case Is Dismissed, Can the Government Re-Indict?
After a dismissal without prejudice, the government can go back to a new grand jury and seek a fresh indictment. The main limit is the statute of limitations. Federal law provides one safety valve: if an indictment is dismissed for any reason after the statute of limitations has expired, the government has six additional months from the date of dismissal to return a new indictment. If the dismissal is appealed, the window is 60 days after the appeal becomes final.12Office of the Law Revision Counsel. 18 USC 3288 – Indictments and Information Dismissed After Period of Limitations That extension does not apply if the original dismissal was itself for a limitations violation, or if some other legal bar blocks re-prosecution.
Double jeopardy can also cut off a refiling. If the dismissal amounted to an acquittal—meaning the judge resolved a factual question about guilt in the defendant’s favor—the government cannot try again, regardless of how the ruling was labeled.13Constitution Annotated. Amdt5.3.6.4 Trial Court Rulings Terminating Trial Before Verdict and Double Jeopardy Dismissals based purely on procedural defects are treated more like mistrials and generally allow the government to start over.
