Unreported / Non-Citable
Background
James Chester Mitchell pleaded no contest in October 2021 to assault with a deadly weapon after an altercation in which his mother's roommate was struck in the head with a baseball bat. He admitted one prior serious felony conviction, and the plea agreement gave him an opportunity to complete a one-year residential treatment program. If he failed, he agreed to the upper term of four years, doubled to eight years under the Three Strikes law, with the court retaining discretion to add five years for the prior serious felony.
Mitchell failed to report to the program and, after a second chance, left after one day. In exchange for dismissal of charges in another case, he agreed to imposition of the stipulated upper-term sentence plus the five-year serious felony enhancement. On appeal, he argued that Senate Bill No. 567, which amended Penal Code section 1170 effective January 1, 2022, barred the upper term absent properly found aggravating circumstances. The Court of Appeal initially rejected that claim, but the California Supreme Court granted review and transferred the matter back with directions to reconsider in light of People v. Mitchell (2026) 19 Cal.5th 729.
The Court’s Holding
The court first rejected the People's argument that the appeal had to be dismissed for lack of a certificate of probable cause. Because Mitchell did not contend his plea was defective when made but instead sought the retroactive benefit of an ameliorative change in law, no certificate was required under People v. Stamps (2020) 9 Cal.5th 685 and People v. Mitchell, supra, 19 Cal.5th at page 749, footnote 7.
On the merits, the court applied the Supreme Court's holding that defendants who agreed to a stipulated upper term may seek the retroactive benefit of amended section 1170(b) unless they validly waive its requirements. The court concluded that remand was appropriate so Mitchell could either waive or invoke section 1170(b)'s requirements. If he reaffirms the bargain and waives those rights, the trial court shall reinstate the original sentence; if he declines, the parties may agree to modify the plea to a middle term doubled under the Three Strikes law, subject to court approval; absent agreement, Mitchell may withdraw his assent, the plea will be set aside, and the matter will proceed as if no plea had been entered.
Key Takeaways
- A defendant seeking retroactive application of an ameliorative sentencing statute need not obtain a certificate of probable cause because such a claim does not attack the validity of the plea as defective when made.
- Under People v. Mitchell (2026) 19 Cal.5th 729, a stipulated upper-term sentence in a plea bargain does not excuse compliance with amended Penal Code section 1170(b) unless the defendant validly waives its requirements.
- On remand, the defendant may reaffirm the plea and waive section 1170(b)'s protections, negotiate a modified middle-term disposition subject to court approval, or withdraw assent and return to a pre-plea posture.
- Senate Bill 567 made the middle term the presumptive prison sentence, permitting an upper term only when aggravating circumstances are stipulated to or found true beyond a reasonable doubt.
- The Court of Appeal vacated its prior decision affirming the judgment after the California Supreme Court transferred the case back for reconsideration in light of its intervening precedent.
Why It Matters
This opinion illustrates the practical reach of the California Supreme Court's decision in People v. Mitchell, confirming that even defendants who expressly bargained for an upper-term sentence may invoke Senate Bill 567's new sentencing protections on nonfinal judgments. It clarifies that a stipulated sentence does not itself constitute a waiver of section 1170(b)'s requirements.
The decision also reinforces the certificate-of-probable-cause framework, confirming that retroactivity-based sentencing challenges survive appeal without a certificate because they do not challenge the plea's validity when entered. Trial courts handling similar plea agreements must now offer defendants the choice to waive or invoke section 1170(b) before reinstating bargained upper-term sentences.
