Error and/or relief
Having been found in violation of probation and the previously imposed but suspended prison term having been ordered executed, the defendant is entitled to challenge the upper term that he agreed to in 2021 before section 1170 was amended to provide that the upper term may be imposed only on aggravating factor stipulated to or found true beyond a reasonable doubt by a jury.
If the prosecution or court are not satisfied with the resulting modification, the plea shall be set aside and the parties shall be restored to their status prior to the plea agreement.
First Holding:
Effective 1/1/2022, SB 567 amended section 1170 to make the middle term the presumptive sentence and permit a trial court to impose the upper term only when there are circumstances in aggravation of the crime that justify the imposition of a term of imprisonment exceeding the middle term and the facts underlying those circumstances have been stipulated to by the defendant or have been found true beyond a reasonable doubt.
Authority:
PEN 1170
Second Holding:
In Mitchell, the California Supreme Court resolved the effect of section 1170(b) on negotiated dispositions, holding that SB 567’s amendments to the statute apply retroactively to sentences imposed pursuant to stipulated plea agreements in cases that were not final on appeal.
Authority:
People v. Mitchell (2026) 19 Cal.5th 729, 735, 737–738
Third Holding:
We therefore reverse the judgment because the facts relied on to justify the upper term were not stipulated to or proven beyond a reasonable doubt at a jury or court trial. The defendantl may reaffirm the bargain and waive the requirements now applicable under section 1170(b), or he may withdraw his plea and return the parties to a pre-plea posture, with the prosecutor bearing its burden of proof. What he may not do, however, is unilaterally obtain a reduction of his agreed-upon upper term sentence to the middle term.
Authority:
People v. Mitchell (2026) 19 Cal.5th 729, 735, 749
Gary note:
(The opinion made no mention of Penal Code section 1171, effective 1/1/2025, even though the Mitchell opinion made an observation in a footnote. There are several unpublished cases that have held that section 1171 will NOT result in a rescission of the plea agreement, in light of the language in 1171(c)(3) that says, “Any changes to a sentence shall not be a basis for a prosecutor or court to rescind a plea agreement.” (You can search for the unpublished opinions I have posted, where I may have added additional commentary. Maybe try the search term “1171” or “PEN 1171” with or without quotation marks.)
(On May 18, 2026, the Supreme Court decided People v. Mitchell (2026) 19 Cal.5th 729. It was an appeal directly from the original sentencing under section 1170, and did not arise out of a ruling on the application of any other ameliorative statutes. The question was “Does Senate Bill No. 567 (Stats. 2021, ch. 731), which limits a trial court’s discretion to impose upper term sentences, apply retroactively to defendants sentenced pursuant to stipulated plea agreements?”
(The court concluded that it does apply (section 1170 as amended by SB 567), but it remanded with the Stamps remedy–that if the defendant opts to claim the benefits of section 1170 and the resulting sentence is something the DA or the court are not happy with, the plea will be set aside and the parties restored to their pre-plea bargain status.
(But it contained a very important footnote:
(“Shortly before oral argument, counsel for Mitchell filed a letter with this court identifying section 1171 as a new authority. Section 1171, effective January 1, 2025 (Stats. 2024, ch. 964, § 2) sets forth procedures governing a “ ‘postconviction proceeding,’ ” which the statute defines as “a proceeding to modify a sentence or conviction pursuant to an ameliorative statute. Ameliorative statutes include, but are not limited to, Sections 1170.18, 1172.1, 1172.6, 1172.7, and 1172.75.” (§ 1171, subd. (a).) At oral argument, counsel for Mitchell urged that this statutory definition broadly encompasses a remand to the trial court in the context of a direct appeal under the authority of section 1170(b) and Estrada. We decline to consider this argument because we have concluded that Mitchell is entitled to a remand under our established precedent in Stamps. We express no view on the applicability of section 1171 to this case or how it might affect the options described above. Mitchell may raise this issue in the Court of Appeal or the trial court in the first instance.”
(On remand, the Court of Appeal issued its new opinion–this time unpublished–in which it further remanded the case to the trial court for resolution in light of the Supreme Court decision. And in that unpublished opinion, it stated, “We now find that Mitchell’s section 1171 arguments should be resolved first by the trial court. Accordingly, we remand this action to that court for further proceedings consistent with Mitchell II [the Supreme Court decision]. On remand, Mitchell may raise her contentions regarding section 1171.”)
