Error and/or relief

The court erred in denying his petition either because the court either improperly shifted the burden to the defendant to prove his mental disorder was a significant factor in his charged crimes, or because substantial evidence does not support a finding by clear and convincing evidence that his mental disorder was not such a factor.

First Holding:

Penal Code section 1001.36 provides that a defendant in a criminal case is eligible for mental health diversion if he demonstrates: (1) he has been diagnosed with a recognized mental disorder; and (2) that disorder was a significant factor in the commission of the charged crime.

The defendant bears the burden of making a prima facie showing that he or she meets the minimum requirements of eligibility for diversion. However, if the defendant has been diagnosed with a mental disorder, the court shall find that the defendant’s mental disorder was a significant factor in the commission of the offense unless there is clear and convincing evidence that it was not a motivating factor, causal factor, or contributing factor to the defendant’s involvement in the alleged offense.

Authority:

PEN 1001.36(b)(2)

People v. Gerson (2022) 80 Cal.App.5th 1067, 1078–1079

Second Holding:

Additionally, the statute gives the trial court discretion to deny diversion even if the statutory requirements are met. However, this residual discretion must be exercised consistent with the principles and purpose of the governing law.

Authority:

Vaughn v. Superior Court (2024) 105 Cal.App.5th 124, 134

Lacour v. Superior Court (2025) 110 Cal.App.5th 391, 401

Third Holding:

We review the trial court’s denial of mental health diversion for abuse of discretion. A court abuses its discretion when it makes an arbitrary or capricious decision by applying the wrong legal standard or when it bases its decision on express or implied factual findings that are not supported by substantial evidence.

Authority:

People v. Pacheco (2022) 75 Cal.App.5th 207, 213

People v. Moine (2021) 62 Cal.App.5th 440, 449

Fourth Holding:

A trial court is not bound by an expert’s testimony and opinion. But even were the court to discount the psychiatrist’s report’s conclusion in its entirety, the absence of evidence proving that petitioner’s mental disorder was a factor in the commission of the offenses is not substantial evidence supporting a finding by clear and convincing evidence that petitioner’s mental disorder was not a factor in the commission of the offenses. It was the prosecution’s burden to present such clear and convincing evidence.

Here, it appears that the court either placed the burden on the defendant to demonstrate his mental disorder was a significant factor in the commission of the charged offenses or found clear and convincing evidence that the mental disorder was not a significant factor. In other words, the court either applied the wrong legal standard or based its decision on a factual finding unsupported by substantial evidence. Either way, reversal is required.

Error and/or relief

The conviction of assault with a firearm is reversed for insufficient evidence.

First Holding:

Section 245(a)(2), criminalizes the commission of an assault upon the person of another with a firearm. Assault is defined by statute as an unlawful attempt, coupled with a present ability, to commit a violent injury on the person of another.

Authority:

PEN 245(a)(3)

PEN 240

Second Holding:

Assault is a general intent crime. It requires proof that the defendant willfully committed an act that by its nature will probably and directly result in injury to another. Further, the defendant must have been aware of the facts that would lead a reasonable person to realize that a battery would directly, naturally and probably result.

Authority:

People v. Williams (2001) 26 Cal.4th 779, 782, 788

Third Holding:

The actus reus of assault is the present ability to commit a violent injury on the person of another. It is the action enabling[a defendant to inflict a present injury. The present ability element is satisfied when a defendant has attained the means and location to strike immediately. In this context, however, immediately does not mean instantaneously. It simply means that the defendant must have the ability to inflict injury on the present occasion even if the defendant is several steps away from actually inflicting injury.

People v. Chance (2008) 44 Cal.4th 1164, 1167-1168, 1172

People v. Licas (2007) 41 Cal.4th 362, 370

Fourth Holding:

As a general rule, a defendant cannot commit assault with a firearm using an unloaded or inoperable weapon, unless the firearm is used as a club or bludgeon. The reason is straightforward: absent the means to fire the weapon, the defendant lacks the present ability to commit a violent injury on the person threatened, in the manner in which the injury is attempted to be committed.

People v. Lee Kong (1892) 95 Cal. 666, 669 [it cannot be said that a person with an unloaded gun would have the present ability to inflict an injury upon another many yards distant]

People v. Chance (2008) 44 Cal.4th 1164, 1167-1168, 1173, fn. 11 [as the unloaded gun cases demonstrate, the defendant must have an actual, not merely apparent, ability to inflict injury]

Fifth Holding:

This rule, however, is not categorical. Consistent with Chance’s explanation that present ability requires only the ability to inflict injury on the present occasion, courts have recognized that an unloaded or inoperable firearm may support assault liability where the evidence establishes the defendant had the means to load and/or render it operable immediately.

Authority:

People v. Lattin (2024) 107 Cal.App.5th 596, 612, 620 [there is no brightline-rule requiring a loaded firearm]

People v. Ranson (1974) 40 Cal.App.3d 317, 321

Sixth Holding:

When considering a challenge to the sufficiency of the evidence to support a conviction, we review the entire record in the light most favorable to the judgment to determine whether it contains substantial evidence—that is, evidence that is reasonable, credible, and of solid value—from which a reasonable trier of fact could find the defendant guilty beyond a reasonable doubt.

We determine whether, after viewing the evidence in the light most favorable to the prosecution, any rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt. This determination presumes in support of the judgment the existence of every fact the trier could reasonably deduce from the evidence.

Authority:

People v. Cardenas (2025) 18 Cal.5th 797, 821

Seventh Holding:

(Gary note: the court then outlined the evidence and concluded that it was insufficient to support this count. The defendant pulled the trigger but the gun was unloaded, and there was no evidence that he had the ability to reload it at the time of the offense. Thus, he had no present ability.)

Accordingly, the conviction on count 2 must be reversed for insufficient evidence, and double jeopardy bars retrial on that charge. The associated firearm enhancement (sec. 12022.5(a)) necessarily falls with the conviction. We vacate appellant’s sentence and remand the matter for resentencing.

Authority:

Lockhart v. Nelson (1988) 488 U.S. 33, 39

Eighth Holding:

A full resentencing is appropriate when part of a sentence is stricken on review. This permits the trial court to exercise its sentencing discretion in light of the changed circumstances.

Error and/or relief

We reverse the juvenile court’s finding that the minor committed murder as an aider and abettor with implied malice.

First Holding:

An aider and abettor of murder must actually aid and abet the lethal act in order to be convicted of murder.

Authority:

People v. Morris (2026) 19 Cal.5th 671, 678

Second Holding:

The trial court announced its finding that, to be liable for an implied malice murder, a direct aider and abettor must, by words or conduct, aid the commission of the life endangering act, not the result of that act. The court treated the robbery as the life-endangering act that resulted in the victim’s death.

The court went on to state that the People have proved beyond a reasonable doubt that the minor was an aider and abettor to the robbery with knowledge that his compatriots intended to commit the robbery; did, in fact, intend to aid the perpetrators in the commission of the robbery or attempted robbery, and had knowledge that the act was dangerous to human life.

The opinion in Morris was issued long after the juvenile court sustained the petition, and under Morris, the court’s reasoning was in error.

Authority:

People v. Morris (2026) 19 Cal.5th 671

Third Holding:

When considering a challenge to the sufficiency of the evidence to support a conviction, we review the entire record in the light most favorable to the judgment to determine whether it contains substantial evidence—that is, evidence that is reasonable, credible, and of solid value—from which a reasonable trier of fact could find the defendant guilty beyond a reasonable doubt.

We determine whether, after viewing the evidence in the light most favorable to the prosecution, any rational trier of fact could have found the essential elements of the crime beyond a reasonable doubt. In so doing, a reviewing court presumes in support of the judgment the existence of every fact the trier could reasonably deduce from the evidence.

The same standard of review governs our review of the sufficiency of evidence in juvenile delinquency cases.

In re Matthew A. (2008) 165 Cal.App.4th 537, 540

Fourth Holding:

Murder is the unlawful killing of a human being, or a fetus, with malice aforethought. An unlawful killing during the commission of a felony is also murder. Second degree implied malice murder is the unlawful killing of a human being with malice aforethought but without the additional elements, such as willfulness, premeditation, and deliberation, that would support a conviction of first degree murder. Malice may be express or implied.

Authority:

PEN 187(a)

PEN 189(a),(e)

People v. Knoller (2007) 41 Cal.4th 139, 151

Fifth Holding:

Malice is implied when the killing is proximately caused by an act, the natural consequences of which are dangerous to life, which act was deliberately performed by a person who knows that his conduct endangers the life of another and who acts with conscious disregard for life. In short, implied malice requires a defendant’s awareness of engaging in conduct that endangers the life of another—no more, and no less. This definition is referred to as “simple implied malice murder.”

Authority:

People v. Knoller (2007) 41 Cal.4th 139, 143

People v. Reyes (2023) 14 Cal.5th 981, 988

Sixth Holding:

To suffice for implied malice murder, the defendant’s act must not merely be dangerous to life in some vague or speculative sense; it must involve a high degree of probability that it will result in death. Implied malice requires a defendant’s awareness of the risk of death to another.

Authority:

People v. Knoller (2007) 41 Cal.4th 139, 152

People v. Reyes (2023) 14 Cal.5th 981, 989

Seventh Holding:

To be considered the proximate cause of the victim’s death, the defendant’s act must have been a substantial factor contributing to the result, rather than insignificant or merely theoretical. The question of implied malice is to be decided in light of all the circumstances.

Authority:

People v. Reyes (2023) 14 Cal.5th 981, 988

People v. Moore (2010) 187 Cal.App.4th 937, 942

Eighth Holding:

Under Penal Code section 187, the mens rea required for murder is malice aforethought. Regarding aiders and abettors, in order to be convicted of murder, a principal in a crime shall act with malice aforethought. Malice shall not be imputed to a person based solely on his or her participation in a crime.

In the context of implied malice murder, the aider and abettor must know the perpetrator intends to commit a life-endangering act, intend to aid the perpetrator in the commission of that act, know the act is dangerous to human life, and act in conscious disregard for human life.

People v. Curiel (2023) 15 Cal.5th 433, 468

People v. Reyes (2023) 14 Cal.5th 981, 991

Ninth Holding:

Murder also requires an actus reus. In the context of implied malice, the actus reus required of the perpetrator is the commission of a life-endangering act. For the direct aider and abettor, the actus reus includes whatever acts constitute aiding the commission of the life-endangering act.

Thus, to be liable for an implied malice murder, the direct aider and abettor must, by words or conduct, aid the commission of the life-endangering act, not the result of that act.

People v. Concha (2009) 47 Cal.4th 653, 660

People v. Reyes (2023) 14 Cal.5th 981, 991

Tenth Holding:

As relevant to this aider or abettor theory of liability in a felony-murder, the amended felony-murder rule now states that when a person was not the actual killer, that person must have, with the intent to kill, aided, abetted, counseled, commanded, induced, solicited, requested, or assisted the actual killer in the commission of murder in the first degree. Section 189(e)(2) requires a nonkiller to aid the actual killer in the lethal act.

While the language of Penal Code section 188(a)(3), differs from section 189(e), pursuant to section 188(a)(3), a direct aider and abettor must act with malice aforethought, and act with intent to aid the life-endangering act of the direct perpetrator that proximately causes the death.

People v. Reyes (2023) 14 Cal.5th 981, 991-992

Eleventh Holding:

Implied malice murder requires attention to the aider and abettor’s mental state concerning the life endangering act committed by the direct perpetrator, such as shooting at the victim, or, as in this case, stabbing him. In other words, the aider and abettor must know the perpetrator intends to commit a life-endangering act, intend to aid the perpetrator in the commission of that act, know the act is dangerous to human life, and act in conscious disregard for human life. Even if the act results in a death that is accidental, the circumstances surrounding the act may evince implied malice.

Twelfth Holding:

SB 1437 abolished the natural and probable consequences doctrine in cases of murder, amending section 188 to require that, when the felony-murder rule does not apply, a principal in the crime of murder shall act with malice aforethought, and that malice shall not be imputed to a person based solely on his or her participation in a crime. As a result, the natural and probable consequences doctrine can no longer support a murder conviction.

People v. Gentile (2020) 10 Cal.5th 830, 847-848

Thirteenth Holding:

Instead, with the exception of section 189(e), a conviction for murder requires that a person act with malice aforethought and that a person’s culpability for murder must be premised upon that person’s own actions and subjective mens rea.

We conclude the legislative language of Penal Code section 188(a)(3) requires a finding that the accused actually aided the perpetrator in the commission of the life-endangering act, and that the accused’s participation in a dangerous felony as an aider and abettor cannot form the basis for finding implied malice.

Only in this way will a finding that the accused aided and abetted in the commission of implied malice murder reflect a determination of the person’s guilt based on his own actions and subjective intent.

Error and/or relief

The trial court erred when it failed to instruct the jury regarding specific intent for count 2, and the trial court abused its discretion when it imposed the registration requirement, We reverse count 2 and strike the registration requirement, and in all other respects affirm.

First Holding:

Trial courts have a sua sponte duty to instruct on every element of charged offenses. Instructions completely removing the issue of intent from the jury’s consideration may constitute a denial of federal due process principles. We review independently the legal adequacy of a jury instruction.

Authority:

People v. Lee (1987) 43 Cal.3d 666, 673,

People v. Cole (2004) 33 Cal.4th 1158, 1211

Second Holding:

The court instructed the jury that count 2 required “general criminal intent,” which is established when the defendant intentionally does a prohibited act.

This instruction was erroneous. The crime in count 2 is a specific intent crime because it requires the act to be done with the intent to accomplish a separate objective.

In addition, the instruction given on the crime was incomplete, because it included the statutory language for the prohibited conduct, but it omitted the requirement that the physical act be performed for a separate reason.

Specific intent is not presumed from the doing of the unlawful act.

Authority:

EVID 668

People v. ZarateCastillo (2016) 244 Cal.App.4th 1161, 1167 [construing equivalent language of a similar section]

Third Holding:

We assess the prejudicial effect of the failure to instruct regarding the required element of mental state pursuant to Chapman. We must reverse unless it appears beyond a reasonable doubt that the error did not contribute to the jury’s verdict.

Instructional error is harmless where a reviewing court concludes beyond a reasonable doubt that the omitted element was uncontested and supported by overwhelming evidence, but not where the record contains evidence that could rationally lead to a contrary finding with respect to the omitted element.

In our view, the instructional error is not harmless because the record contains evidence that could rationally lead to a contrary finding with respect to the omitted element.

People v. Mil (2012) 53 Cal.4th 400, 409

Neder v. United States (1999) 527 U.S. 1, 19

Fourth Holding:

Substantial evidence did not support the trial court’s order that the defendant register as a sex offender. Section 290.006 requires a defendant to register as a sex offender if the court finds at the time of conviction or sentencing that the person committed the offense as a result of sexual compulsion or for purposes of sexual gratification. Section 290.006 does not include sexual abuse as a basis for registration.

Authority:

PEN 290.006

Fifth Holding:

We review imposition of a registration requirement pursuant to section 290.006 for abuse of discretion. The trial court’s findings of fact are reviewed for substantial evidence, its conclusions of law are reviewed de novo, and its application of the law to the facts is reversible only if arbitrary and capricious.

A trial court abuses its discretion when its factual findings are not supported by the evidence. Here, there was no evidence that the murder (count 1) was committed for sexual gratification. The registration requirement must be stricken.

If the defendant is retried on the reversed count by a properly instructed jury, the court may reconsider the registration requirement based on the evidence presented at that trial.

Error and/or relief

There was insufficient evidence to support the allegation that the minor received stolen property in violation of section 496d(a) (pertaining to the vehicle in which he was a passenger).

First Holding:

The same standard governs review of the sufficiency of the evidence in adult criminal cases and juvenile cases. We examine the whole record in the light most favorable to the judgment to determine whether it discloses substantial evidence—evidence that is reasonable, credible, and of solid value—such that a reasonable trier of fact could find the defendant guilty beyond a reasonable doubt.

While substantial evidence includes circumstantial evidence and reasonable inferences drawn therefrom, such inferences may not be based on suspicion alone, or on imagination, or speculation.

In re Anthony J. (2004) 117 Cal.App.4th 718, 728

Third Holding:

Receipt, or possession of stolen property, may be actual or constructive and need not be exclusive. Physical possession is also not a requirement. It is sufficient if the defendant acquires a measure of control or dominion over the stolen property.

Constructive possession occurs when the defendant maintains control or a right to control the property; possession may be imputed when the property is found in a place that is immediately and exclusively accessible to the defendant and subject to his or her dominion and control, or to the joint dominion and control of the defendant and another.

People v. Rushing (1989) 209 Cal.App.3d 618, 621-622

Fourth Holding:

Possession may be established through circumstantial evidence and resulting reasonable inferences. However, mere presence near the stolen property, or access to the location where the stolen property is found is not sufficient evidence of possession, standing alone, to sustain a conviction for receiving stolen property. Something more must be shown to support inferring of dominion and control. The necessary additional circumstances may, in some fact contexts, be rather slight.

People v. Myles (1975) 50 Cal.App.3d 423, 429 [evidence the defendant was passenger in car and found standing close to car trunk containing stolen goods insufficient to infer possession for conviction of receiving stolen property]

People v. Zyduck (1969) 270 Cal.App.2d 334, 336 [evidence defendant was passenger in car with stolen chain saw in rear seat insufficient evidence to infer his possession of stolen item]

Fifth Holding:

The car was stolen and the minor knew the car was stolen, but there is no substantial evidence that the minor possessed or aided in withholding the car from its owner.

While it is true that conscious possession of recently stolen property itself raises a strong inference that the possessor knew the property was stolen, the issue here is whether, as a mere passenger, he actually or constructively possessed the stolen car as a section 496d conviction requires.

Aiding and abetting the commission of a crime requires some affirmative action. Mere presence at the scene of a crime which does not itself assist its commission or mere knowledge that a crime is being committed and the failure to prevent it does not amount to aiding and abetting.

There was no evidence to show the minor directed the driver to speed away from the pursuing officers or otherwise directed any movement of the Infiniti as a passenger. There was no evidence that the minor had an opportunity to get out of the car before the traffic stop, or once the driver sped away from the officers.

The record is also devoid of any evidence regarding the minor’s relationship to any of the other occupants of the car, and the gang expert conceded the minor had no documented gang-related contacts apart from this one incident.

Absent evidence showing the nature and extent of the relationship between the minor and the other occupants, or the circumstances of the minor’s affirmative actions beyond simply running from the Infiniti, we conclude the evidence established nothing more than that the minor was a passenger in the stolen car, but not that he aided and abetted in the vehicle theft or in withholding the stolen vehicle from its rightful owner.
