Pre-Accusation Delay and Due Process (Before the Speedy-Trial Clock Starts)

Why the Speedy-Trial Clock Does Not Run Before Arrest or Charge

The speedy-trial right protects an accused, and a person does not become an accused until arrest or formal charge. Delay before that moment — between the offense and the accusation — is not a speedy-trial issue at all. A different set of rules, built on limitations statutes and due process, governs that earlier stretch of time.

In United States v. Marion, the Supreme Court held that the Sixth Amendment “has no application until the putative defendant in some way becomes an accused,” and it declined to extend that protection to the period before arrest. Betterman v. Montana later mapped the criminal timeline into three stages, each with its own check against delay. Knowing which stage a delay falls in tells you which doctrine — and which motion — applies.

The practical consequence is that a defendant charged years after the alleged offense, but tried promptly after arrest, generally has no speedy-trial claim. The complaint about the years of delay belongs in a due-process motion, analyzed under the standards described below, not in a Barker motion. This is why identifying the exact date of arrest or formal charge is the first step in any delay analysis: everything before that line is measured by limitations and due process, and everything after it by the speedy-trial right. That single date can change the entire analysis, because a delay that is fatal under one doctrine may be irrelevant under the other. Pinning it down from the arrest records, the charging instrument, and the docket is the practical starting point of any challenge based on delay.

The Statute of Limitations Is the Primary Safeguard

Because the Constitution imposes no speedy-trial deadline before accusation, the statute of limitations does most of the work. Marion called limitations the foremost safeguard against stale charges. Texas fixes these deadlines by statute, and once a limitations period expires, the prosecution is barred outright, without any need to prove prejudice.

Texas sets its criminal limitations periods in article 12.01 of the Code of Criminal Procedure. The periods vary by offense: many felonies carry a three-year default, while others — certain thefts, fraud, and sexual offenses — carry longer periods, and some offenses, including murder, have no limitations period at all. When no limitation applies, the State may indict decades later, as it did in the leading Texas case discussed below.

A limitations bar is a clean, categorical defense: if the indictment is presented after the period runs, the charge is dismissed regardless of how strong the evidence is. That is why limitations, not the Constitution, is the first thing to check when a case involves old conduct. The due-process doctrine only becomes relevant where the indictment is timely under article 12.01 but the pre-accusation delay was still long enough to raise fairness concerns. Limitations periods generally run from the date the offense was committed to the date the indictment or information is presented, and specific statutes can lengthen or, for a handful of grave offenses, eliminate the period entirely. Confirming the correct period for the exact offense charged is therefore the threshold question, before any constitutional argument is reached.

The Due-Process Backstop: A Demanding Two-Prong Test

Where a charge is filed within the limitations period, the Due Process Clause offers a narrow safety valve for extreme delay. It is demanding. A Texas defendant must show two things: that the delay caused substantial prejudice to the right to a fair trial, and that the State used the delay as an intentional device to gain a tactical advantage.

Marion first framed this test, and the Texas Court of Criminal Appeals adopted it in State v. Krizan-Wilson. There, the State indicted the defendant for a murder committed nearly twenty-three years earlier. The trial court dismissed the case, but the Court of Criminal Appeals reversed, holding that the defendant had to demonstrate both substantial prejudice and an improper, tactical purpose behind the delay — and had failed on the second prong. A long gap and some prejudice, without proof of tactical intent, is not enough.

The court also set the standard of review. It gives almost total deference to the trial court’s fact findings, including its assessment of the State’s motive, but reviews the ultimate legal conclusion about a due-process violation de novo. That makes the evidentiary hearing decisive: the defense must build a record on both prejudice and purpose, because an appellate court will not reweigh credibility. The court weighs the prejudice to the defendant and the length of the delay against the State’s reasons for waiting, and only a delay that offends fundamental conceptions of justice will support dismissal. A long gap alone, however striking, does not meet that standard without the required showing on both prongs.

Investigative Delay Does Not Violate Due Process

The reason the second prong is so hard to meet is that the law protects the State’s legitimate need to investigate before charging. A prosecutor who waits to be sure of the case is doing the job correctly, not violating due process. Only delay aimed at hurting the defense, not delay aimed at building the case, offends the Constitution.

In United States v. Lovasco, the Supreme Court held that prosecuting a defendant after investigative delay does not deny due process “even if his defense might have been somewhat prejudiced by the lapse of time.” Prosecutors are under no duty to charge as soon as probable cause exists; indeed, the Court noted it would be improper to seek an indictment before the prosecutor is satisfied the case can be proven. Investigative delay, the Court explained, is “fundamentally unlike” delay undertaken solely to gain a tactical edge.

Krizan-Wilson applied the same logic on the state side. The court observed that a lengthy delay caused merely by a difference of opinion among prosecutors about the strength of a case does not violate due process. Absent positive proof of an improper purpose, the fact that charges could have been filed sooner does not, by itself, make the delay unconstitutional. Lovasco underscored that prosecutors act properly when they wait until they are satisfied they can prove guilt beyond a reasonable doubt, not merely until probable cause exists. Requiring charges the moment probable cause appears would pressure prosecutors to file cases they are not ready to prove, harming both the accused and the public interest in sound charging decisions.

Proving Substantial Prejudice From the Delay

Even though prejudice alone is not enough, it is a necessary first prong, and it must be substantial and concrete. Vague claims that time has dimmed memories will not do. The defense must identify specific harm to the ability to defend the case that the passage of years actually caused.

Lovasco described prejudice as “generally a necessary but not sufficient element” of a due-process claim, and stressed that the inquiry must weigh the reasons for the delay alongside the harm. Concrete prejudice usually means something that can be named: a death or disappearance of a material witness who would have testified for the defense, the loss or destruction of physical evidence or records, or an alibi that can no longer be reconstructed because the relevant people or documents are gone.

The defense should document what specific evidence existed at the time of the offense and show why the delay — not the defendant’s own inaction — caused its loss. Generalized assertions that witnesses “probably” forgot details, without a showing of how those details mattered to the outcome, fall short. The stronger the concrete showing of prejudice, the more a court will scrutinize the State’s explanation for waiting, though the defendant must still satisfy the separate purpose prong. In practice, the defense preserves this record early, often by moving to identify and secure witnesses, sending preservation requests for records and physical evidence, and documenting what was available at the time of the offense. That contemporaneous record is what later distinguishes genuine, delay-caused prejudice from the ordinary dimming of memory that time produces in every case.

Proving the State's Improper, Tactical Purpose

The second prong is where most pre-accusation claims fail. The defendant must offer positive proof that the State delayed to gain a tactical advantage or for another improper purpose — not merely argue that the trial court could have disbelieved the prosecution’s explanation. Suspicion and hindsight are not evidence of bad faith.

In Krizan-Wilson, the defendant had the burden at the hearing to prove the delay was an intentional device to gain an advantage. The Court of Criminal Appeals held it was not enough to argue the judge might have disbelieved the State’s witnesses; the defendant had to present affirmative proof of an improper purpose and had not. The witnesses, including a retired detective, testified that the delay reflected good-faith disagreement about the strength of the case, not any strategy to disadvantage the defense.

This is a high bar by design, because the alternative would let courts second-guess ordinary charging decisions. As Lovasco warned, the Due Process Clause does not permit courts to abort prosecutions simply because they disagree with a prosecutor’s judgment about when to seek an indictment. A pre-accusation due-process motion therefore succeeds only in the unusual case where the record affirmatively shows the State sat on the case to weaken the defense. Evidence of that kind might include internal communications revealing a decision to wait out a defense witness, or an admission that charging was deferred to disadvantage the accused. Without such affirmative proof, courts presume the delay reflected legitimate charging judgment, and the motion is denied.

How This Differs From a Speedy-Trial Motion

A pre-accusation due-process motion and a speedy-trial motion answer different questions and use different tests, even though both complain about delay. Choosing the right one matters, because raising a speedy-trial claim about pre-charge delay invites a quick denial on the ground that the clock had not yet started.

The two doctrines diverge on every element. The speedy-trial right runs from arrest or charge and is analyzed under the four Barker factors, where the State’s negligence can count against it and extraordinary delay can be presumptively prejudicial. The due-process doctrine runs from the offense to the accusation, demands substantial prejudice plus intentional tactical delay, and gives the State the full benefit of legitimate investigative time. Negligence that would help a Barker claim is irrelevant to a due-process claim, which requires deliberate misconduct.

In a case that spans both stages — a long pre-charge delay followed by a long post-charge delay — each period is analyzed under its own doctrine. Counsel may file a due-process motion aimed at the pre-accusation years and a separate speedy-trial motion aimed at the post-arrest years, keeping the two timelines and the two legal standards distinct so the court can rule on each without confusion. Framing the motions separately also avoids a common pitfall: labeling a pre-charge complaint as a speedy-trial claim, which invites a swift denial on the ground that the Sixth Amendment clock had not yet begun. Matching each argument to the stage of delay it addresses gives the court a clean path to the merits of each. In a due-process motion, the heading and argument should invoke the Fifth and Fourteenth Amendment Due Process Clauses and the two-prong Krizan-Wilson standard, while a speedy-trial motion should invoke the Sixth Amendment, article I, section 10, and the Barker factors. Aligning the citations with the correct doctrine keeps the court from applying the wrong test to the wrong period of delay.

• United States v. Marion, 404 U.S. 307 (1971) — The Sixth Amendment speedy-trial right attaches only at arrest or formal charge; pre-accusation delay is governed by limitations and due process.
• United States v. Lovasco, 431 U.S. 783 (1977) — Investigative pre-indictment delay does not violate due process even if it prejudices the defense; prosecutors need not charge upon probable cause.
• State v. Krizan-Wilson, 354 S.W.3d 808 (Tex. Crim. App. 2011) — A due-process dismissal for pre-indictment delay requires both substantial prejudice and proof the State delayed intentionally to gain a tactical advantage.
• Betterman v. Montana, 578 U.S. 437 (2016) — The speedy-trial right attaches at arrest or accusation and detaches at conviction; statutes of limitations and due process guard other stages.
