Error and/or relief
The trial court erroneously denied Penal Code section 1172.6 resentencing relief at the prima facie stage. We reverse the trial court’s order denying resentencing relief and direct the trial court to issue an order to show cause.
First Holding:
SB 1437, effective as of January 1, 2019, made ameliorative changes to our state’s homicide law. As part of these ameliorative changes, malice, a key element the People must prove in a murder prosecution, may no longer be imputed to a defendant solely because the defendant participated in another crime. This means, for instance, that a defendant is no longer guilty of murder as an aider and abettor solely because the natural and probable consequences of that other crime included a confederate’s commission of murder.
Authority:
People v. Patton (2025) 17 Cal.5th 549, 558
Second Holding:
These ameliorative changes apply retroactively through the resentencing process set forth in section 1172.6. Those convicted of murder or attempted murder under certain imputed malice theories may seek resentencing. So may a person convicted of manslaughter who was charged with murder when three conditions apply. First, the charging document allowed the prosecution to proceed under a theory of murder in which malice is imputed to a person based solely on that person’s participation in a crime. Second, the petitioner accepted a manslaughter plea offer in lieu of a trial on such a murder charge. And third, the petitioner could not presently be convicted of murder because of the changes to homicide law that took effect in 2019.

Third Holding:
Upon receipt of a facially sufficient petition — along with briefing in opposition or support — the trial court holds a hearing to determine whether a petitioner has made a prima facie case for relief. If so, the court issues an order to show cause and then holds an evidentiary hearing to determine entitlement to relief. If not, the court denies the petition.

Fourth Holding:
We independently review a trial court’s conclusion that a petitioner failed to make a prima facie case for relief. The record of conviction informs the prima facie determination. And that record includes a preliminary hearing transcript preceding a guilty plea. A court, however, may not engage in factfinding, weigh the evidence, or make credibility determinations at the prima facie stage.

People v. Patton (2025) 17 Cal.5th 549, 559, 568
Fifth Holding:
A review of the preliminary hearing transcript in this case reveals that it possible the defendant could have been convicted at trial under a now-invalid theory. There was witness testimony that two unidentified men initiated the attack, which raises at least a triable issue as to whether the defendant was the actual killer, and if he was not, whether he knew of and intended to aid in the criminal purpose of the actual killer as required for direct aiding and abetting. Given this state of the record of conviction, the defendant’s guilty plea to voluntary manslaughter does not prove that he could still be convicted of murder under current law.
