What is an Arbuckle Waiver?

Posted by Dmitry Gorin | Jun 24, 2025

For a criminal defendant in California who has entered a plea agreement, a thorough understanding of their rights is not only important but also essential. It's a crucial aspect that empowers you and provides a sense of security. These rights, as per California law, grant the defendant the legal right to be sentenced by the same judge who accepted their plea bargain.

Arbuckle Waiver
An Arbuckle Waiver means waiving the right to have the same judge who accepted your plea bargain also handle your sentencing.

The concept of Arbuckle rights, which originated from the 1978 case People v. Arbuckle, is a significant legal development. In this case, the California Supreme Court acknowledged the defendant's right to have the sentencing judge who accepted their plea bargain also preside over their sentencing.

The rationale behind this right is not just based on the judge's familiarity with the case, but also the assurance of a fair and appropriate sentence. This should give you, as a defendant, confidence in the legal process.

Simply put, an Arbuckle waiver is a significant decision. It's when you choose to forego the right to have the same judge who accepted your plea bargain also handle your sentencing hearing. It's essential to note that you have the right to have the same judge for both stages of the process; however, you waive this right with an Arbuckle waiver.

Supreme Court

The Supreme Court recognized the general principle that you have a right to have the sentencing judge be the same judge who accepted your plea deal if the trial court judge retained sentencing discretion pursuant to your plea agreement.

They also recognized that the identity of the sentencing judge was a significant factor in your decision to plead guilty to a crime, even if it was a misdemeanor. If the judge who accepted your plea bargain retained sentencing discretion, this became an implied term in the plea agreement. You have a right to enforce that implied term of the agreement.

It's crucial to note that there may be situations where your California criminal defense attorney advises you to waive your rights. This decision, commonly referred to as an Arbuckle waiver, can have significant and far-reaching implications. Let's delve into your Arbuckle rights in more detail and discuss when waiving them may be more beneficial, as well as the potential risks involved.

What are the Arbuckle Rights?

In most cases, it serves the defendant's best interest to have the same judge who accepted their plea bargain also preside over their sentencing. This judge has a deeper understanding of the case and may consider any mitigating factors or other aspects that may warrant a more lenient sentence.

Arbuckle Rights

Additionally, having the same judge for both proceedings can also provide a sense of continuity and consistency in the judicial process. For Arbuckle's rights to apply, the judge who accepted your plea must also retain sentencing discretion. In the eyes of the courts, this effectively becomes an "implied term" of the plea bargain. 

Your Arbuckle rights are important to your case because it's not just about the judge accepting your plea agreement; it's also about you accepting it. The judge's role in the process is to ensure fairness and uphold the integrity of the plea-bargaining process.

The idea is that your choice to accept a plea agreement might have been influenced by the judge's implied promises or expectations, and switching judges after a plea deal has been reached could result in a different sentence than was implied or expected. Enforcing your Arbuckle rights ensures that the integrity of the plea-bargaining process is maintained and that you decided to plead guilty with a clear understanding of the sentencing implications. 

This process involves notifying the court of your intention to enforce your Arbuckle rights and ensuring that the sentencing judge is the same as the one who accepted your plea agreement.

Arbuckle Waiver Quick Facts

  • An Arbuckle waiver occurs when a defendant willingly relinquishes their Arbuckle rights, meaning they agree to allow a different judge to handle their sentencing.
  • Signing an Arbuckle waiver typically involves a formal process where the defendant acknowledges their understanding of the rights they are giving up and the potential consequences thereof.
  • The process often includes a formal document that the defendant must sign, indicating their voluntary decision to waive these rights.
  • An Arbuckle waiver introduces an element of unpredictability into the sentencing phase, as different judges may have varying perspectives on the severity of punishment.
  • The consequences of waiving these rights can be significant, such as leading to a less favorable sentencing outcome than expected.
  • A defendant's decision to waive these rights should be made carefully, considering the potential outcomes.

Conditions for Considering a Waiver

There are several scenarios where filing an Arbuckle waiver might be advantageous. These include the following:

  • Strategic Considerations. In some cases, the defense might assess that a different judge could offer a more favorable sentencing outcome due to various factors such as judicial temperament, sentencing trends, or specific legal interpretations. For instance, if the original judge has a history of imposing harsh sentences for similar cases, it might be strategic to consider a different judge for sentencing.
  • Expediency. Scheduling conflicts or other logistical issues with the original judge might lead to substantial delays in sentencing. Agreeing to an Arbuckle waiver in such instances can expedite the sentencing process, which might be in the defendant's best interest, especially if time in custody is a concern.
  • Judicial Unavailability. Suppose the original judge who accepted the plea is unavailable due to retirement, illness, or other reasons. In that case, an Arbuckle waiver allows the sentencing to proceed without waiting for the judge's return or replacement.

When Should You Enforce Your Rights?

While there are situations where waiving Arbuckle rights might be strategic, there are also circumstances where it may be in your best interests to enforce your Arbuckle rights and demand sentencing from the same judge who took your plea agreement. Here are some reasons to enforce these rights:

  • Maintaining Consistency and Fairness. If the plea agreement included specific understandings or assurances from the judge regarding sentencing, keeping the same judge is the best way to ensure these expectations are honored. This consistency is vital for the defendant to feel that the plea was entered fairly and with full knowledge of the likely outcome. It also ensures that the judge is familiar with the case details and the defendant's circumstances, which can influence the sentencing decision.
  • Familiarity with Case Details. From the beginning, a judge involved in the case is more likely to have a nuanced understanding of the circumstances, including any mitigating factors or complexities that should influence sentencing. This detailed knowledge can be advantageous to the defendant.
  • Legal Strategy. In instances where the defense's strategy relies heavily on the interpretations or sentiments of the original judge, maintaining that judge for sentencing can be integral to achieving the desired legal outcome.

Why You Need a Defense Lawyer

You do not have to waive your rights under the Fifth Amendment if you are a criminal defendant in California. They are implied terms in the plea agreement, meaning they are valid unless you waive them. It is up to the district attorney to show that you made an Arbuckle waiver. The district attorney must provide evidence that you knowingly and voluntarily waived your rights.

Even if you do not affirmatively invoke your Arbuckle rights, they are not forfeited. For more information, contact our criminal defense law firm, Eisner Gorin LLP, located in Los Angeles, CA.
