To win dismissal under the actual prejudice standard for pre-indictment delay, you have to prove two things at once: that the gap between the alleged offense and the charges caused specific, concrete harm to your defense, and that the government had no legitimate reason for waiting. Neither half is enough on its own. Real damage to your case paired with a good-faith investigation will not get the indictment thrown out, and even obvious prosecutorial foot-dragging will not help you if you cannot point to defense evidence that is actually gone. The Supreme Court itself has acknowledged that very few defendants ever clear this bar, and understanding why starts with what the word “actual” demands.1Justia. United States v. Lovasco, 431 U.S. 783 (1977)
What Counts as Actual Prejudice
The word “actual” is doing the work. You cannot win by arguing that long delays are inherently unfair or that time probably eroded your case in some unspecified way. Courts expect you to point to something concrete that is now missing from your defense, and to explain what it would have shown.
Two categories cover most successful showings.
Lost or Destroyed Evidence
Physical evidence degrades. Surveillance footage gets overwritten on short retention cycles. Financial records are discarded under routine business policies. Forensic samples become unusable. If you can identify a specific piece of evidence that was favorable to your defense and is now gone because of the delay, that counts toward the first prong. But you have to say what it would have proved. Noting that old files no longer exist does not get you there.
Unavailable Witnesses
A witness who could have supported your alibi may have died, moved overseas, or become impossible to locate. Faded memory can be just as damaging. When a witness can no longer recall the details of an event from years earlier, your ability to cross-examine the prosecution’s version of that event shrinks.
Specific, Favorable, Substantial
Three qualifiers run through everything a court will accept. The missing material has to be specific — identified, not hypothetical. It has to be favorable to your defense, not merely relevant to the case. And the prejudice has to be substantial enough that it could realistically have changed the outcome at trial. Peripheral losses, or information that duplicates evidence you still have, will not satisfy the prong.
This is where most claims fall apart. Defendants know something is gone but struggle to prove what it would have shown, because the very fact that it is gone makes that proof difficult to produce. A destroyed alibi video would have shown you were somewhere else, but if you cannot describe its contents with precision, courts treat the claim as speculative.
The Second Prong: Why the Government Waited
Even once you establish real harm to your defense, the court still examines the reason for the delay. The two prongs operate together, and the government’s justification can defeat an otherwise strong prejudice showing.
Reasons Courts Accept
Investigative delay is the most common justification and the one courts consistently accept. Prosecutors are allowed to take the time needed to identify all participants, gather sufficient evidence, and determine whether guilt can be proven beyond a reasonable doubt. In United States v. Lovasco, the Supreme Court held that a prosecutor who waits to build a stronger case or finish an investigation is not violating your rights, even if the delay causes some harm to your defense. Due process concerns arise only when the delay is undertaken “solely to gain tactical advantage over the accused.”1Justia. United States v. Lovasco, 431 U.S. 783 (1977)
Protecting the identity of undercover officers or informants is another accepted reason. In drug cases, prosecutors sometimes wait to file charges until an undercover operation concludes, so bringing one case does not compromise others still in progress.
Reasons That Cross the Line
The clearest violation is deliberate stalling for a tactical edge. Waiting for a defense witness to die, hoping records will be destroyed, or sitting on charges to pressure a defendant into cooperating against someone else are the kinds of bad-faith conduct the doctrine is built to catch.
Administrative convenience falls on the wrong side as well. A prosecutor who simply has not gotten around to filing your case, or who deprioritized it in favor of other matters, is not conducting a legitimate investigation. In United States v. Marion, the government tried to justify a delay by pointing to understaffing in the U.S. Attorney’s office. The Court did not treat that as a blanket excuse.2Legal Information Institute. United States v. Marion, 404 U.S. 307 (1971)
How Much Bad Faith You Must Prove Depends on the Circuit
Federal courts do not agree on exactly how much improper intent the second prong requires, and the disagreement can determine whether your claim is viable at all.
- Most federal circuits apply a strict two-prong test: you must prove both actual prejudice and that the government deliberately delayed to gain a tactical advantage or for some other bad-faith purpose. Negligence or indifference by the prosecution is not enough.
- Some circuits use a burden-shifting approach. Once you establish actual prejudice, the government must come forward with a legitimate reason for the delay, and failure to do so can support a due process violation.
- A minority of circuits apply a balancing test, weighing the prejudice you suffered against the government’s reasons without requiring proof of intentional misconduct. Serious harm plus a weak justification can add up to a violation even without bad faith.
The practical consequence is significant. In a strict-test circuit, a prosecutor who negligently sat on your case for years while critical evidence vanished may face no consequences. In a balancing circuit, the same facts could lead to dismissal. Knowing which approach your jurisdiction follows is one of the first things to pin down.3Congress.gov.

Why These Claims Rarely Succeed
The Supreme Court noted in Lovasco that “so few defendants have established that they were prejudiced by delay” that courts have had little sustained opportunity to develop the doctrine further.1Justia. United States v. Lovasco, 431 U.S. 783 (1977) That observation from 1977 still holds. Several features of the test work against defendants.
The specificity requirement creates a catch-22. You have to explain what the lost evidence would have proved, but the reason you cannot produce it is the very delay you are complaining about. Courts treat vague descriptions as speculation.
The intent prong filters out the most common type of delay. Many cases sit unfiled because of understaffing, competing priorities, or bureaucratic inertia. In circuits requiring proof of deliberate tactical advantage, none of those reasons supports a claim, even when the practical damage to the defendant is identical to what intentional delay would cause.
And courts give prosecutors wide latitude to decide when a case is ready. The line between “still investigating” and “just sitting on it” is blurry, and judges tend to resolve ambiguity in favor of the prosecution’s characterization.
When There Is No Statute of Limitations
The stakes rise sharply for offenses like murder that carry no statute of limitations. For those crimes, there is no external clock forcing the government to act, which makes due process the only constitutional check on how long the prosecution can wait before filing.
The legal standard does not change. You still have to prove actual prejudice and improper government intent under the same framework. What shifts is the practical dynamic: the government cannot point to an approaching deadline as evidence that it moved reasonably. Cold cases revived by new forensic techniques are a common setting, and courts have generally found that pursuing a prosecution after new evidence like DNA analysis emerges reflects a legitimate investigative purpose, even when the original delay stretched for decades.3Congress.gov.

What a Successful Claim Produces
The remedy is dismissal of the charges. There is no halfway measure. A court will not exclude a piece of evidence or give a jury instruction about the delay to even things out. If you prove both prongs, the indictment goes away. That all-or-nothing quality is part of why the standard is so demanding: judges are cautious about dismissing criminal cases entirely, especially serious ones, and the severity of the remedy reinforces the severity of the burden you have to carry to earn it.
