Waiving your right to a speedy trial means agreeing to let your criminal case take longer than the statutory deadline normally allows. In federal court the government has 70 days from indictment to bring you to trial, and most states set their own windows somewhere between 60 and 180 days. Signing away that protection stops the clock, gives both sides more room to work, and leaves your case unresolved for longer. The decision is almost always strategic, and in most cases your defense attorney will recommend it.
What You’re Actually Pausing
The Sixth Amendment guarantees anyone accused of a crime the right to a speedy trial.1Legal Information Institute. Sixth Amendment The Constitution doesn’t put a number on “speedy,” so Congress added one through the Speedy Trial Act of 1974: the government must indict within 30 days of arrest and start trial within 70 days of the indictment or your first court appearance, whichever is later.2Office of the Law Revision Counsel. 18 USC 3161 – Time Limits and Exclusions Every state has its own version, with deadlines that typically run from 60 days to six months depending on the jurisdiction and the severity of the charge.
Those are the clocks a waiver stops. The underlying constitutional right can also be waived, but the Supreme Court has held that giving up a constitutional right requires an “intentional relinquishment or abandonment of a known right,” not silence or inaction.3Cornell Law School.

How a Waiver Happens
Federal and state courts handle this very differently, and that distinction trips people up.
Federal Court Doesn’t Accept a Direct Waiver
In federal court you cannot simply sign a form giving up the Speedy Trial Act. The Supreme Court confirmed this unanimously in Zedner v. United States in 2006, and the Department of Justice instructs prosecutors never to rely on a defendant’s unilateral waiver.4United States Department of Justice Archives. Criminal Resource Manual 628 – Speedy Trial Act of 1974 When both sides want more time, the mechanism is an “ends of justice” continuance. The judge has to find on the record that the benefits of the delay outweigh the public’s interest and your interest in a prompt trial, and must state specific reasons.2Office of the Law Revision Counsel. 18 USC 3161 – Time Limits and Exclusions
Acceptable reasons include unusual case complexity, the defense needing reasonable preparation time, or situations where going forward on schedule would cause a miscarriage of justice. A packed court calendar or an unprepared prosecutor is not enough. Once the judge grants the continuance, that period is excluded from the 70-day count.
State Court Usually Allows a Direct Waiver
Most state courts let you waive the statutory deadline directly. The process typically involves signing a written waiver and confirming the decision on the record in open court. The judge will question you to make sure the waiver is knowing and voluntary, meaning you understand what you’re giving up and no one pressured you into it. Your attorney and the prosecutor generally sign the document as well, and the judge reviews it before accepting it.
Why Defense Attorneys Usually Recommend It
Rushing to trial rarely helps the defense. The prosecution has been building its case since before your arrest. Your attorney is playing catch-up from day one, and the clock is already running. Common reasons to slow things down:
- Reviewing discovery. The prosecution has to turn over its evidence, which in a serious case can mean hundreds of pages of police reports, forensic results, financial records, and witness statements. Digesting all of it inside 70 days is sometimes impossible.
- Running an independent investigation. Tracking down defense witnesses, hiring an investigator, or visiting a scene takes time.
- Hiring experts. Forensic, financial, or technical cases often need experts who require weeks or months to analyze findings and prepare testimony.
- Negotiating a plea. Prosecutors tend to offer better terms once both sides have fully evaluated the case, which usually doesn’t happen until well after discovery is complete.
- Waiting for favorable developments. A co-defendant’s case may resolve in a way that helps you, or the evidentiary picture may shift.
What You Give Up by Waiving
Delay is not free. The reasons the right exists in the first place are the same reasons waiving it carries real costs.
Evidence decays. Witnesses forget details, move, or become hard to locate. Physical evidence can be lost or degraded. Security footage gets overwritten. If your defense depends on a particular witness or piece of evidence, every month of delay raises the chance it won’t be available at trial. The Supreme Court has recognized impairment of the defense as the most serious form of prejudice from delay.5Constitution Annotated. Amdt6.2.5 Modern Doctrine on Right to a Speedy Trial
If you couldn’t make bail, every day of delay is a day in custody without a conviction. Pretrial incarceration can cost you your job, your housing, and your relationships. Even defendants out on bail live with restrictions on their freedom, ongoing anxiety, and the financial drain of an unresolved case. The Court in Barker v. Wingo acknowledged that extended life under a cloud of suspicion is itself a form of prejudice.5Constitution Annotated. Amdt6.2.5 Modern Doctrine on Right to a Speedy Trial
There’s a legal cost too. Once you’ve agreed to slow things down, it becomes much harder to argue later that the delay violated your rights.
Delays That Pause the Clock Without a Waiver
Not every delay eats into the speedy trial deadline. Federal law automatically excludes certain events, and most state statutes have similar categories. Knowing which delays pause the clock on their own matters, because there’s no reason to sign away your rights to accommodate a delay that’s already excluded.
Under the Speedy Trial Act, the clock stops automatically for things like:2Office of the Law Revision Counsel. 18 USC 3161 – Time Limits and Exclusions
- Pretrial motions, from filing through ruling. This covers motions to suppress evidence, dismiss charges, or compel discovery.
- Mental competency evaluations ordered by the court.
- Interlocutory appeals by either side.
- Time the court spends considering a proposed plea agreement.
- Periods when a key witness can’t be located despite reasonable effort, or when a defendant flees.
- Reasonable delay tied to a co-defendant whose own clock hasn’t expired.
The practical result is that the actual calendar time between arrest and trial is almost always much longer than the statutory deadline, even when nobody waives anything. A federal case with a 70-day deadline may take six months or more once excludable time is counted.
Taking a Waiver Back
A waiver isn’t necessarily permanent. In state courts that allow direct waivers, you can usually withdraw yours by filing a written demand for speedy trial. That puts the prosecution and the court on notice that you want the case resolved on the statutory timeline.
Filing a demand doesn’t rewind the clock to where it was before. Instead, a new speedy trial period typically starts running from the date of the demand, and the prosecution gets the full statutory window from that date. Some jurisdictions require notice to all parties, and some require a showing of good cause before a court will vacate a scheduled trial date to set an earlier one.
In federal court, where the mechanism is an ends-of-justice continuance rather than a direct waiver, the dynamic shifts. Once the continuance expires, the clock resumes. If the defense opposes any further delay, the judge needs independent grounds to grant another continuance, and you can effectively force the issue.
One Protection That Survives a Waiver
Even after you’ve waived the statutory clock, the Due Process Clause still provides a backstop against extreme government delay. To win on due process grounds you have to show the government intentionally delayed to gain a tactical advantage and that the delay caused actual prejudice to the defense.4United States Department of Justice Archives. Criminal Resource Manual 628 – Speedy Trial Act of 1974 That is a much harder showing than the statutory deadline requires, which is why the decision to waive is worth thinking through carefully before you sign anything.
