Quick answers
Did CA AB 46 pass?
Yes. CA AB 46 has been enacted into law. Latest recorded action (2026-06-29): Chaptered by Secretary of State - Chapter 18, Statutes of 2026.
What is CA AB 46 about?
Existing law authorizes a court to grant pretrial diversion to a defendant suffering from a mental disorder, on an accusatory pleading alleging the commission of a misdemeanor or felony offense, in order to allow the defendant to undergo mental health treatment. Existing law provides that a defendant is eligible for diversion if they have been diagnosed with certain mental disorders and the court finds that the mental disorder was a significant factor in the commission of the charged offense, unless there is clear and convincing evidence that the disorder was not a motivating, causal, or contributing factor to the defendant's involvement in the alleged offense. Existing law prohibits defendants charged with specified offenses, including murder, from being placed in this diversion program. This bill would require that the diagnosis or rediagnosis with a mental disorder be within 5 years before the alleged offense. Existing law makes a defendant suitable for this diversion program if, among other criteria, a qualified mental health expert opines that the defendant's symptoms of the mental disorder that caused, contributed to, or motivated the criminal behavior, would respond to mental health treatment and the defendant will not pose an unreasonable risk of danger to public safety if treated in the community, as specified. The bill would revise that standard and instead require the court to find that the defendant will not pose a substantial and undue risk to the physical safety of another person if treated in the community. The bill would require the mental health expert's opinion to include that the proposed mental health diversion plan is clinically appropriate to address the symptoms of the defendant's mental disorder, as specified. The bill would require the court to state the reasons for denial on the record.
