If you or a loved one is facing criminal charges in California, the government does not have an unlimited amount of time to bring your case to trial.
Under the Sixth Amendment to the U.S. Constitution, the California Constitution (Art. I, § 15), and California Penal Code § 1382, criminal defendants have a fundamental right to a speedy trial.
When law enforcement or prosecutors unreasonably delay your case, your defense attorney can file a Serna Motion—a formal legal request asking the court to dismiss all criminal charges.
What is a Serna Motion in California?
A Serna motion asks the court to dismiss criminal charges because the defendant's constitutional or statutory right to a speedy trial was violated. Established by the landmark California Supreme Court case Serna v. Superior Court (1985), a granted Serna motion results in the complete dismissal of the misdemeanor or felony charges.
California Speedy Trial Deadlines: Penal Code 1382 PC
Under California Penal Code § 1382 (PC 1382), the state must bring a defendant to trial within strict statutory timeframes following arraignment, unless "good cause" for a delay is proven.
Statutory Trial Timelines in California
|
Case Type |
Defendant Custody Status |
Deadline to Begin Trial |
| Misdemeanor | In Custody | Within 30 calendar days of arraignment |
| Misdemeanor | Out of Custody | Within 45 calendar days of arraignment |
| Felony | In or Out of Custody | Within 60 calendar days of arraignment |
Note: If the prosecution fails to meet these strict deadlines without showing legal "good cause" (or if the defendant has not waived time), the court must grant a motion to dismiss.
When Does the Speedy Trial Clock Start in California?
Determining exact statutory and constitutional trigger points is crucial to calculating whether a violation has occurred. The speedy trial "clock" typically begins upon:
-
The date of arrest (for constitutional speedy trial rights)
-
The formal filing of an indictment or information
-
The date of arraignment (for statutory rights under PC 1382)
-
Being held to answer following a felony preliminary hearing
How Courts Evaluate a Serna Motion: The 4-Factor Test
When deciding a constitutional speedy trial claim, California judges apply the balancing test established by the U.S. Supreme Court in Barker v. Wingo. The court weighs four primary factors:
-
Length of the Delay: Delays exceeding one year in misdemeanor cases (between complaint and arrest) are presumptively prejudicial under Serna v. Superior Court.
-
Prosecution's Reason for Delay: Unjustified law enforcement inaction, systemic court congestion, or prosecutor negligence favor dismissal. Valid reasons include missing material witnesses or ongoing complex investigations.
-
Defendant's Assertion of Rights: Whether the defendant actively demanded a speedy trial rather than consenting to delays.
-
Prejudice to the Defendant: Demonstrating actual harm caused by the delay, such as:
-
Loss or destruction of key exculpatory evidence
-
Defense witnesses moving, dying, or suffering memory loss
-
Prolonged pretrial incarceration and anxiety
-
Waiving vs. Asserting Your Speedy Trial Rights
Defendants are often asked to "waive time" during court appearances. Waiving speedy trial rights pauses the clock and gives the court permission to schedule trial dates beyond the statutory 30-, 45-, or 60-day limits.
Why Defense Counsel Might Recommend Waiving Time:
-
Preparation Time: Collecting forensic evidence, hiring expert witnesses, or subpoenaing records.
-
Plea Negotiations: Negotiating reduced charges or alternative sentencing with the prosecutor.
-
Witness Availability: Aligning court dates with critical defense witness schedules.
Caution: Never waive your speedy trial rights without consulting an experienced criminal defense lawyer. Unintentionally waiving time can waive your ability to file a PC 1382 motion to dismiss.
California Serna Motion vs. Penal Code 1050 Motion to Continue
-
Serna Motion (or PC 1382 Motion): Filed by the defense seeking permanent dismissal of charges due to past, unconstitutional trial delays.
-
Penal Code 1050 Motion: A formal request filed by either party asking the court to postpone an upcoming court date. Prosecutors must show explicit "good cause" when filing a PC 1050 motion to delay a trial past statutory limits.
Frequently Asked Questions (FAQs)
What happens if a Serna motion is granted in California?
If a Serna motion is granted, the judge dismisses the pending criminal charges. For most misdemeanors, this dismissal permanently bars re-prosecution.
What is the difference between statutory and constitutional speedy trial rights?
Statutory rights under PC 1382 provide strict 30-, 45-, or 60-day deadlines following arraignment. Constitutional rights (under the 6th Amendment and CA Constitution) protect against broader pre-arraignment and pre-arrest prosecution delays based on overall fairness and prejudice.
Can a felony case be refiled after a speedy trial dismissal?
Under California's "two-dismissal rule" (Penal Code § 1387), the prosecution can generally refile a felony charge one time after an initial dismissal. However, if a felony case is dismissed twice due to speedy trial violations, it is permanently barred.
How does a federal speedy trial claim differ from a California claim?
Under the federal Speedy Trial Act (18 U.S.C. § 3161), federal prosecutors must bring an indicted defendant to trial within 70 days. Unlike California state law, the federal statutory clock generally does not begin until a formal indictment or information is filed in court.
