Sentencing Reform and Resentencing: AB 600 in California Explained

For a long time, California has led the nation in criminal justice reform. The government is constantly reevaluating how punishment is supposed to function in a contemporary society, from lowering prison population to giving people who have served lengthy sentences a second chance. 

Assembly Bill 600 (AB 600 in California), which became operative on January 1, 2025, is among California’s most significant new reforms.

So, What is AB 600 in California?

For decades, people knew California’s sentencing laws as some of the harshest in the country, which contributed to prison overpopulation and impacted communities of color disproportionately. In an effort to give those who transformed their lives an actual opportunity to reintegrate into society, legislators and advocacy organizations have pushed for reforms.

Because of the introduction of AB 600, California judges can now recall and reduce sentences without a recommendation from the district attorney or the California Department of Corrections and Rehabilitation (CDCR). It’s a big step forward from prior regulations that severely limited who could receive resentencing and when.

This change is significant because it gives many prisoners who previously had no viable way to petition the court access. It also represents California’s broader shift away from mandatory severe penalties and toward a more tailored approach that considers equity and rehabilitation.

Background of AB 600

Prior to AB 600, resentencing usually required outside assistance. Judges couldn’t start the process themselves, so district attorneys or the CDCR had to suggest that a court reevaluate a sentence. Many families were frustrated because they could see signs of rehabilitation, but were left without a legal way to proceed. 

By giving judges the authority to act when justice demands it, AB 600 aims to bridge that gap.

Key Changes in the Law

The most significant shift under AB 600 is the authority it gives to judges. Courts are no longer required to await a petition from the criminal justice system or prosecutors. Rather, if it is in the interests of justice, judges have the authority to independently recall and alter sentences at any time. This modification makes it easier for people, who might otherwise be disregarded, to access resentencing.

How AB 600 Changes Resentencing in California

To understand the impact of AB 600, let’s see how resentencing looked like before versus how it looks now.

In the past, resentencing was rare because it relied on outside referrals. A judge had no justification or power to review a sentence unless the CDCR or the district attorney’s office flagged a case. The slow and selective referral process often left thousands of incarcerated people without hope, even when resentencing occurred. 

With AB 600, the landscape looks very different. The judge now has complete discretion to consider the case, and an inmate or their lawyer may petition the court directly. The law encourages judges to consider things like public safety, rehabilitation, and whether the initial sentence was too harsh. As a result, the procedure is more flexible and responsive to unique situations.

Who Qualifies for Resentencing Under AB 600?

Although the law purposefully grants judges broad authority to consider petitions, not all inmates are eligible. This is intended to help courts consider the full person rather than strict cutoffs.

The length of the initial sentence (particularly if it was disproportionately lengthy in comparison to cases of a similar nature) , the inmate’s rehabilitation during incarceration, and any modifications to the individual’s circumstances, such as age, health, or family support, are some of the most frequent factors. Judges also consider whether resentencing would endanger public safety. Lastly, AB 600 highlights the value of equity and calls on judges to take into account racial and economic inequities when determining sentences.

Here’s a list of some key considerations:

Eligibility Factor	What Judges Consider
Sentence Length	Was the punishment excessive compared to the crime?
Rehabilitation	Has the person completed programs, obtained education, or demonstrated personal growth?
Age & Circumstances	Was the offender very young at the time of the crime, or do health issues now play a role?
Public Safety	Would release or sentence reduction put the community at risk?
Equity Considerations	Does resentencing help correct systemic disparities?

The Resentencing Process in California: Step-by-Step

1. First case evaluation

Get the client’s complete case file, including the judgment, sentencing minutes, probation report, charging documents, and any previous petitions or appeals, and have a lawyer (or qualified legal reviewer) read it. This review establishes the most compelling legal and factual justifications for resentencing as well as basic eligibility.

2. Determine relief and legal theory.

Choose the action you want the court to take (e.g., recall and reduce the sentence, recall and resentence to time served, amend parole/probation conditions). The petition should specify why AB 600 applies and which legal standard supports relief in this particular case.

3. Assemble supporting evidence

Get records that demonstrate rehabilitation and improved circumstances, such as work histories, disciplinary records demonstrating good behavior, medical records if relevant, certificates from educational or treatment programs, and any other concrete evidence of improvement. Obtain letters of support from program supervisors, family members, employers, clergy, and community leaders. 

These resources serve as the foundation of an effective petition.

4. Get input from the community and victims (if applicable)

Record any outreach or statements involving victims or victim advocates. Judges take victim input into account. When appropriate, draft sincere, lawyer-vetted letters of apology or restorative justice.

5. Write a draft motion or petition.

Create a well-structured legal motion that includes the requested relief, the factual background, citations to the relevant documents (statutes, court decisions, and the content of AB 600), and supporting documentation. 

If relief is granted, include a proposed amended judgment or order for the judge to sign.

6. File the petition with the court and serve parties

In accordance with local laws, submit the petition to the sentencing court (format, filing fees, or fee waiver). Serve the petition to all relevant parties, including the CDCR and the district attorney. It’s necessary to file proof of service.

7. Keep an eye on responses and time frames

The prosecution (and occasionally CDCR) will have a chance to reply after filing. Courts have the authority to schedule briefings or request more documents. S tay updated on any court orders, opposition papers, or motions.

8. Prepare for the hearing

If the court schedules a hearing, plan your evidence and advocacy strategy, including which witnesses will testify, which exhibits will be presented, who will give victim or community statements, and which legal points to highlight. Subpoena witnesses or experts if their testimony strengthens the case.

9. The court hearing

Both sides present their arguments and supporting documentation during the hearing. The prosecution may object, while the defense highlights rehabilitation, mitigating circumstances, and why resentencing is just. The judge has the authority to weigh public safety concerns, ask questions, and take victim input into account.

10. Court ruling

The petition will either be denied or the judge will grant relief (i.e. reducing the sentence, recall and resentence to a lesser term, or ordering release). While some judges take the case under submission and then issue a written decision, others issue an order immediately.

11. Post-decision procedures

If resentencing is granted, the court will notify custody authorities to implement release or recalculated custody time and sign an amended judgment or order. If rejected, discuss your options with your attorney, which may involve a motion for reconsideration, more proof, or, if necessary, other post-conviction remedies.

12. Compliance and follow-through

Verify that all documentation is submitted to the proper authorities, that probationary or parole requirements are updated, and that any necessary transitional services (such as housing, work, or health care) are set up. Keep a copy of the court’s order in the client’s file.
