Legal Basis for a Serna Motion – Right to a Speedy Trial

California law and U.S. Supreme Court precedent establish that unreasonable trial delays violate the right to due process and a fair trial. Courts assess the following legal standards:

• California Constitution, Article I, Section 15 – Protects the right to a speedy and public trial.
• Sixth Amendment to the U.S. Constitution – Prevents excessive delays in criminal prosecutions.

Key Court Cases Supporting Serna Motions

Several court rulings have upheld dismissals due to trial delays:

• Barker v. Wingo (1972) 407 U.S. 514 – Prosecutors must justify trial delays, and delays cannot harm the defense.
• Garcia v. Superior Court (1984) 163 CA3d 148 – If a key witness is lost due to delay, the burden shifts to the prosecution to explain the delay.
• Serna v. Superior Court (1985) 40 C3d 239 – If a defendant’s right to a speedy trial is violated, the charges must be dismissed.

When Can You File a Serna Motion?

A Serna Motion is appropriate when a criminal case is delayed without valid justification. Some common scenarios where this motion may apply include:

• The prosecution fails to bring a case to trial within a reasonable time.
• A key witness or evidence is lost due to the delay.
• The delay prevents the defense from preparing a strong case.

Courts assess four main factors when deciding whether a trial delay violates the right to a speedy trial and whether the case should be dismissed under a Serna Motion:

• The length of the delay – Was it months or years longer than legally allowed?
• The reason for the delay – Was it due to prosecutorial negligence or misconduct?
• The impact on the defense – Did the delay result in lost evidence or witnesses?
• Whether the accused asserted their right – Did they request a timely trial?

How a Serna Motion Helped Reduce Charges in a High-Stakes Case

Case Background

In a Los Angeles murder case, our criminal defense attorney Arash Hashemi used a Serna Motion to challenge a 24-month trial delay that harmed the defense. The client was originally charged with murder under Penal Code 187(a) and faced a potential 25-year-to-life sentence.

Why the Serna Motion Was Critical

• The prosecution delayed the case for two years, preventing a fair trial.
• A key defense witness disappeared due to the delay, making it impossible to present crucial testimony.
• The prosecution failed to disclose the witness’s contact information in time, violating discovery rules.

This delay severely weakened the ability to present a self-defense claim, which could have fully exonerated the client.

Case Outcome – Murder Charge Dismissed, Sentence Reduced

Due to the Serna Motion, the court acknowledged the delay’s impact and allowed a charge reduction:

• The murder charge was dismissed.
• A plea agreement for voluntary manslaughter was reached.
• The sentence was reduced from 25 years to 6 years.

What Happens If a Serna Motion is Granted?

If a Serna Motion is granted, the case is dismissed entirely, meaning there is no conviction, no jail time, no fines, and no probation, and the charges cannot be refiled. If the motion is denied, the case proceeds to trial, but the defense can still use the delay as a factor in plea negotiations or sentencing reductions.

• The criminal charges are dropped, and there is no conviction.
• There is no jail time, fines, or probation.
• The case cannot be refiled.

How to Prove a Violation of Speedy Trial Rights

• A significant delay occurred in the case.
• The delay harmed the ability to present a fair defense.
• The prosecution failed to justify the delay.

Key Evidence That Strengthens a Serna Motion

• Court records showing the length of the delay.
• Proof that a key witness or evidence was lost.
• Documents showing the prosecution withheld critical information.

Frequently Asked Questions About Serna Motions

How long can a case be delayed before filing a Serna Motion?
There is no strict time limit, but delays longer than one year are often considered unreasonable by the courts. The longer the delay, the stronger the argument for dismissal, especially if the delay has affected the ability to present a fair defense.

Can a Serna Motion get my charges dismissed completely?
Yes, if the court finds that the delay was unjustified and caused harm to the defense, the case can be dismissed entirely, meaning no conviction, no penalties, and no chance for the prosecution to refile the charges.

Do I need a lawyer to file a Serna Motion?
Yes. A Serna Motion requires legal expertise to prove that the delay violated the right to a speedy trial and caused actual harm. An experienced criminal defense attorney can gather evidence, argue the motion effectively, and increase the chances of getting the case dismissed.
