California Senate Bill 483: Automatic Resentencing and Judicial Limits

California Senate Bill 483 is a 2021 law that retroactively cancels two sentence enhancements the Legislature had already repealed going forward, and it requires the state to find people still serving time on those enhancements and resentence them without making anyone file a petition. Governor Newsom signed it in 2021, and as of December 2024 more than 3,000 people had been resentenced under it, with a median sentence reduction of roughly two years.¹

Which Enhancements the Law Cancels

SB-483 targets two enhancements and no others.

The first is the prior drug conviction enhancement under Health and Safety Code 11370.2. Before SB-180 took effect on January 1, 2018, California added a consecutive three-year term for each prior felony conviction of certain drug offenses. SB-180 eliminated most of those enhancements for new cases, but people sentenced before 2018 kept serving the extra time. SB-483 declares those enhancements legally invalid.²

The second is the prior prison term enhancement under Penal Code 667.5(b). Before SB-136 took effect on January 1, 2020, California added one year for each prior separate prison term a person had served. SB-136 narrowed the enhancement so it applies only to prior convictions for sexually violent offenses. SB-483 retroactively invalidates the old one-year enhancements for everyone else.³

Roughly 92% of the people resentenced so far had the one-year prior prison term enhancement rather than the three-year drug enhancement.¹

Who Qualifies and Who Does Not

You qualify if your current sentence includes one of those two invalidated enhancements. Eligibility does not depend on the nature of the underlying conviction, prior criminal history, or behavior while incarcerated. If the sentence includes an invalidated enhancement, the California Department of Corrections and Rehabilitation (CDCR) is required to flag it.⁴

Two narrow exceptions carry the enhancement forward:

If the prior prison term enhancement was based on a conviction for a sexually violent offense as defined in Welfare and Institutions Code Section 6600(b), the enhancement remains valid.⁵
If the drug enhancement was imposed for a prior conviction involving the use of a minor in a controlled substance offense under Health and Safety Code 11380, the enhancement remains valid.²

How Resentencing Happens Without a Petition

You do not file anything to start this process. That is the point of the statute. CDCR’s Secretary and each county’s correctional administrator were required to review their populations, identify everyone serving a sentence that includes one of the invalidated enhancements, and send that person’s name, date of birth, and case number to the sentencing court. CDCR also shared those lists with the Judicial Council, the California Public Defenders Association, and the California District Attorneys Association.⁵⁴

Once the court receives notification and confirms the sentence includes an invalidated enhancement, it must recall the sentence and resentence the person. That step is mandatory, not discretionary. The court must appoint counsel for the resentencing regardless of ability to pay. Both sides can agree to waive the hearing, which is common in straightforward cases, and the person can appear remotely if they consent.⁵

When the amended sentence makes someone immediately eligible for release, CDCR regulations require release within five business days of receiving the amended order from the court. CDCR will only accept those documents directly from the court, not from a defense attorney, the incarcerated person, or a family member.⁴

When a Judge Can Refuse to Reduce the Sentence

The default outcome is a shorter sentence. A judge can only decline to reduce it if the prosecution shows, by clear and convincing evidence, that a lesser sentence would endanger public safety. Even where that showing is made, the new sentence can never exceed the original one.⁵

Clear and convincing evidence is a deliberately high bar, above the preponderance standard used in most civil matters. In weighing public safety, the court can consider the person’s disciplinary record and rehabilitation while incarcerated, whether age, time served, or declining health have reduced the risk of future violence, and whether circumstances have changed enough since the original sentencing that continued incarceration no longer serves justice.⁵

The court also has to apply current Judicial Council sentencing rules and any other changes in law that reduce sentences or expand judicial discretion. So the judge is not just subtracting the invalid enhancement. The whole sentence gets reassessed under today’s legal framework.

Plea Deals Stay Intact

Many affected sentences came from plea bargains, and for a stretch some courts let prosecutors withdraw from those deals when a resentencing dropped the term below what the plea specified. That created real hesitation about accepting relief.

Assembly Bill 2483, signed in 2024, closed that door. It added Penal Code Section 1171(c)(3), which states that changes to a sentence during postconviction resentencing under an ameliorative statute cannot be used as a basis for a prosecutor or court to rescind a plea agreement.⁶ The protection covers SB-483 resentencing. If the original sentence came from a plea deal and included an invalidated enhancement, the plea stays in place after the sentence is reduced.

If the Automatic Process Missed Someone

The statutory deadlines for CDCR to notify the courts and for courts to complete resentencing have all passed. Most eligible people have already been identified. Systems still miss people. If you believe someone is still serving time on an invalidated enhancement and has not been resentenced, contact the public defender’s office in the county where the original sentence was imposed. Because the court is required to appoint counsel for the resentencing proceeding itself, legal representation during the hearing does not cost anything.

Keep the CDCR document rule in mind. Even if a private attorney identifies the problem, CDCR will not act until the amended sentencing order reaches it through the court. Once that happens and the amended sentence makes the person immediately releasable, the five-business-day clock starts, so families should have housing and transportation ready.⁴

What the Outcomes Look Like

Of the more than 3,000 people resentenced as of December 2024, roughly 1,118 had been released from CDCR custody. About 1,901 remained incarcerated, either still serving their base term or serving valid enhancements. The median time those individuals had already spent in prison was slightly under 13 years, and nearly two-thirds had served at least a decade.¹

A reduction under SB-483 does not always mean walking out the door. For a large share of people it means an earlier release date on a sentence they are still working through. For the rest, it means release, and quickly.
