PA Rule 600: Excludable Time, Due Diligence, and Remedies

Pennsylvania Rule 600 is the state’s speedy trial rule, and it gives prosecutors a hard deadline to bring your case to trial. If you are free on bail, the Commonwealth has 365 days from the date the criminal complaint was filed. If you are being held in jail because you could not post bail, that window shrinks to 180 days. Miss either deadline and the consequences are serious: dismissal of all charges in the first case, release on nominal bail in the second. The rule only applies to court cases (misdemeanors and felonies). Summary offenses are not covered.¹

The authority for Rule 600 comes from the speedy trial guarantees in both the Sixth Amendment and Article I, Section 9 of the Pennsylvania Constitution.² But Rule 600 is a procedural rule with specific numbers attached, and that is what makes it useful.

When the Clock Starts

Both the 365-day and 180-day clocks begin running on the date the written criminal complaint is filed. That is not the same as the date you were arrested, though in most cases the two happen the same day. When the dates differ, the complaint date controls.¹

A few other events can start a fresh clock:

If a case is transferred from juvenile court to the criminal division, the clock starts from the date the transfer order is filed.
If you were in the Accelerated Rehabilitative Disposition program and got terminated, a new clock starts from the date of the termination order.
If you win a new trial — through a successful appeal, a mistrial, or a withdrawn guilty plea — a new 365-day period begins. When the trial court orders the new trial itself, the clock runs from the date of that order. When an appellate court sends the case back, it runs from the date the appellate court notifies the parties that the record has been remanded.¹

When the Clock Stops

Trial is considered to have started on the date the trial judge calls the case to trial, or on the date you enter a guilty or no-contest plea.¹ Note what this means: the clock stops when the judge calls the case, not when a jury is sworn or when the first witness takes the stand. A plea counts because it resolves the case entirely.

Excludable Time Is Where the Fight Happens

The raw deadline is only the starting point. Both sides will argue over which delays should be subtracted from the count, effectively pausing the clock and pushing the deadline later. This is where most Rule 600 motions are won or lost, and the rules work differently depending on whether you are on bail or in jail.

The 365-Day Rule

For bail cases, only delays caused by the Commonwealth’s failure to exercise due diligence count against the 365-day limit. Everything else is excluded: defense continuances, your lawyer’s unavailability, court scheduling problems, judicial calendar conflicts.¹ The prosecution gets a lot of breathing room this way. Even delays caused by the court itself (an overcrowded docket, no courtroom available) are excludable because they are not delays “caused by the Commonwealth.”³

There is a ceiling on that principle. The Pennsylvania Supreme Court has recognized that when court-caused delay becomes so extreme that it impairs a constitutional right, it stops being just a scheduling issue and becomes a constitutional problem.

The 180-Day Rule

For incarcerated defendants, the math flips. Only delays caused by the defense are excluded. Every other delay counts against the 180 days, including court scheduling delays and even delays where the prosecution was reasonably diligent.⁴ If you are sitting in jail, a congested docket works in your favor. If you are out on bail, the same congestion works against you.

What Counts as Defense Delay

Three categories of delay get attributed to the defense and excluded from both calculations:

Fugitive time — the period between complaint filing and arrest, if you could not be found despite reasonable effort.
Express waivers of Rule 600 rights.
Continuances requested by the defense, your absence from a hearing, or your attorney’s unavailability.¹

What Due Diligence Looks Like

For the 365-day bail rule, the central question is whether the prosecution exercised due diligence. The Pennsylvania Supreme Court has described this as a fact-specific inquiry that “does not require perfect vigilance and punctilious care, but merely a showing the Commonwealth has put forth a reasonable effort.”¹

In practice, prosecutors show due diligence by documenting that they were ready for trial and that external factors prevented it. A missing courtroom, a witness with a medical emergency — those delays will not count against the Commonwealth if the prosecutor was otherwise prepared. But a prosecutor who sat on the case for months without basic scheduling effort will have a hard time explaining it away.

One recurring issue is the withdrawn-and-refiled complaint. If the Commonwealth withdraws a complaint and refiles it, the clock can reset to the second filing date, but only when the withdrawal was driven by factors outside the prosecution’s control and the refiling was not a maneuver to dodge Rule 600. Courts examine refilings closely.

Continuances Are How You Waive Without Realizing It

Every time your lawyer asks for a continuance, those days get excluded from the Rule 600 count as defense-caused delay.¹ More time to review discovery, more time to prepare, a scheduling conflict on your lawyer’s end — all of it comes off the clock. By the time 365 days have passed on the calendar, you may have already given back enough time to kill any motion.

If you are watching the Rule 600 deadline, you and your attorney need to be deliberate about which continuances you request and which you push back against. The rule also requires judges to record who requested each continuance and to specify which party gets the delay attributed to them, so there is a paper trail you can later work from.¹

Filing the Motion

To invoke Rule 600, you or your attorney must file a written motion before trial starts and serve a copy on the prosecutor at the same time.¹ The motion itself is a line-by-line accounting exercise. You start with the complaint date, count forward 365 days to the raw deadline, then add back every day of excludable delay. The resulting “adjusted run date” is the real deadline. If trial had not started by that date, the motion has traction. For 180-day motions, you subtract only defense delays and leave the rest in the count.

The hearing that follows is a paper fight. The judge reviews docket entries and continuance records to decide whether each delay should count. The Commonwealth carries the burden of justifying any period it claims should be excluded, so ambiguous continuance records tend to hurt the prosecution. A one-day miscount can sink the motion, so the breakdown needs to be exact.

The Two Remedies Are Not the Same

What you win depends on which deadline was broken, and the difference matters enormously.

365-Day Violation

If the 365-day limit has been breached, the remedy is dismissal of all charges with prejudice.¹ “With prejudice” means the Commonwealth cannot refile the same charges. The prosecution ends without anyone ever reaching the merits.

180-Day Violation

If you have been held pretrial beyond 180 days in violation of Rule 600(B), you must be released immediately on nominal bail, subject to any nonmonetary conditions the court sets. The charges are not dismissed.⁴ You get out of jail, but the case continues against you. The exception is defendants who are not entitled to bail under Article I, Section 14 of the Pennsylvania Constitution, who cannot be released under this provision.

Do not confuse the two. A successful 180-day motion does not end your case. To get outright dismissal, you still have to wait for the 365-day clock to run out.

The Constitutional Backup

Rule 600 is a procedural rule with fixed numbers. The constitutional right to a speedy trial is broader and more flexible, and the two claims can be raised together. Sometimes the constitutional argument saves a defendant whose Rule 600 motion fails on the math.

Under Barker v. Wingo, courts weigh four factors on a constitutional speedy trial claim: the length of the delay, the reason for it, whether you asserted the right, and whether you were prejudiced by the wait.⁵ There is no fixed number of days. A 400-day delay might be constitutional if the reasons were legitimate; a 300-day delay might not be if the prosecution deliberately dragged its feet and you suffered real harm. If your Rule 600 motion is denied because the adjusted run date had not expired, preserving the Barker argument for appeal is worth doing.
