Is It Possible to Reverse a Plea Deal in California?

If you are facing criminal charges in California and the evidence against you appears strong, your attorney may recommend negotiating a plea deal. In some cases, the prosecution may also initiate plea negotiations.

A plea agreement allows a defendant to plead guilty or no contest in exchange for reduced charges, dismissed counts, or a lighter sentence.

While plea deals often provide certainty and reduce risk, many defendants later wonder whether they can undo or reverse a plea bargain.

The short answer is: yes, but only in limited circumstances. The Hedding Law Firm is here to help. Schedule your consultation at (866) 986-2092 or contact us here. 

Are Plea Deals Final in California?

As a general rule, once a defendant enters a guilty or no-contest plea and the court accepts it, the plea agreement becomes binding. You cannot withdraw a plea simply because you regret the decision or believe you could have obtained a better deal.

However, California law recognizes that plea agreements must be voluntary, knowing, and intelligent. When that standard is not met, a plea may be withdrawn or declared invalid.

A plea deal can be undone in three ways:

  1. The defendant files a motion to withdraw the plea
  2. The prosecution withdraws from the agreement before it is finalized
  3. A judge declares the plea agreement void

What Does California Penal Code 1018 Say About Withdrawing a Plea?

California Penal Code 1018 governs when and how a defendant may withdraw a guilty or no-contest plea.

The statute requires that pleas be entered voluntarily and with a full understanding of the rights being waived.

Courts are instructed to liberally construe Penal Code 1018 to promote justice, especially where a defendant was unrepresented or misinformed.

Under this law, a defendant may withdraw a plea upon a showing of good cause.

How Can You File a Motion to Withdraw a Plea Under PC 1018?

To reverse a plea deal, the defendant must file a motion to withdraw the plea under Penal Code 1018. This motion must explain why the plea was not voluntary, informed, or legally valid.

Examples of “Good Cause” to Withdraw a Plea

Courts may allow withdrawal of a plea when:

  • The defendant was not fully informed of the consequences of the plea or the rights being waived

  • The plea was entered under duress, coercion, or undue pressure

  • The defendant received ineffective assistance of counsel

  • A mental health condition impaired the defendant's ability to make an informed decision

  • New evidence has emerged that fundamentally changes the case

The burden is on the defendant to show good cause, and supporting declarations or evidence are often required.

When Can a Motion to Withdraw a Plea Be Filed?

In most cases, a motion to withdraw a plea must be filed:

In limited situations, courts may consider later motions if justice requires it, particularly when constitutional violations are involved.

Can the Prosecution Back Out of a Plea Deal?

Although uncommon, prosecutors may withdraw from a plea agreement before the plea is entered and accepted by the court.

Common Reasons a Prosecutor May Withdraw

  • New evidence significantly changes the case

  • The defendant provided false or misleading information

  • A procedural or legal error invalidates the agreement

  • The prosecution believes the plea no longer serves justice

While professional ethics generally discourage prosecutors from backing out without cause, it does occasionally happen.

Can a Judge Declare a Plea Deal Void?

Yes. A judge has the authority to declare a plea agreement void if the defendant violates its terms or if the agreement was not legally valid.

Common Reasons a Judge May Void a Plea Deal

  • Failure to appear in court

  • Failed drug or alcohol testing

  • Failure to complete the required programs or community service

  • Commission of a new crime

Once a plea is voided, the defendant may face the original charges and potential penalties.

What Happens When a Plea Deal Is Reversed?

If a plea agreement is withdrawn or declared invalid:

  • The original charges are reinstated

  • Any benefits of the plea deal are lost

  • The case returns to its pre-plea status

Unless a new agreement is negotiated, the defendant may face trial and more severe sentencing exposure.

What If You Violate the Terms of a Plea Deal?

Violating the terms of a plea agreement can result in serious consequences, including:

  • A formal warning

  • Additional fines or penalties

  • Imposition of a previously suspended jail sentence

  • Complete reversal of the plea deal

  • Immediate incarceration

Judges may show leniency if the violation was unintentional and supported by a valid explanation, but this is not guaranteed.
