California Cracks Down: Diversion Doors Slam

California’s mental health diversion reform is not really a story about one judge, one defendant, or even one headline-grabbing failure. It is a story about where the state now draws the line between treatment and public safety, and AB 46 marks a clear shift toward giving judges more room to deny diversion when the risk looks too high.

Intro

AB 46 narrows access to mental health diversion by tightening eligibility and expanding judicial discretion.
The bill raises the public-safety threshold and tells judges to weigh a defendant’s full criminal history, not just the current charge.
Supporters say the reform fixes a system they viewed as too easy to exploit after violent reoffenses.
Critics say the new standards are so demanding that diversion will become functionally unavailable for many people who need treatment.

What AB 46 actually changes

At the center of AB 46 is a rebalancing of discretion. Under the earlier diversion framework, courts could steer some defendants with mental disorders into treatment instead of prosecution, but AB 46 makes it harder to qualify and easier to deny relief when the court believes community treatment would create serious danger. The bill also requires courts to look beyond the immediate case and consider the defendant’s broader history, including prior convictions, arrests, probation or parole violations, and past diversion failures. That is not a cosmetic change. It alters the decision-making frame from a narrow snapshot of the charged offense to a much fuller assessment of risk.

The statute also adds a recency requirement: the diagnosis, or rediagnosis, must fall within five years before the alleged offense to support diversion. In practical terms, that means the law is trying to distinguish between current, clinically grounded need and older or stale diagnostic records. The Senate Public Safety analysis describes another important shift: the old standard of “unreasonable risk of danger” gives way to a broader “substantial and undue risk to the physical safety of another person,” which expands the judge’s authority to deny diversion. AB 46 also expressly adds attempted murder to the list of excluded offenses.

Why prosecutors pushed for the change

Prosecutors did not sell AB 46 as an anti-treatment bill; they sold it as a correction to what they viewed as a dangerous overcorrection. Fresno County and other district attorneys argued that the prior law had given too little room to deny diversion even when the facts suggested a defendant posed a serious public-safety threat. That argument gained political traction because it was paired with vivid cases and with the broader claim that diversion had become too permissive in serious cases. The public-facing case for reform was simple: if a court can foresee a serious risk, it should not be forced to ignore it in the name of therapeutic idealism.

Governor Gavin Newsom’s signing statement reflected that same synthesis. He said the bill preserves diversion for people who can benefit from it while ensuring judges retain discretion to protect victims. That phrasing matters because it reveals the governing logic of the reform. AB 46 does not abandon diversion; it redraws its boundary. Supporters are not trying to end treatment as a legal option. They are trying to make “treatment instead of custody” contingent on a more demanding showing that the defendant is genuinely a good candidate for community-based care. In the language of criminal justice policy, this is retrenchment, not repeal.

The force of the strongest criticism

The most serious objection to AB 46 is not that it ignores public safety; it is that it may overcorrect so aggressively that diversion becomes inaccessible for the very people it was designed to help. The Ella Baker Center argued in the Senate analysis that the bill would effectively eliminate mental health diversion by creating impossible eligibility standards, and that diversion itself reduces recidivism by more than 30% compared with prison. That critique deserves real weight because it attacks the mechanism of the bill, not just its politics. If diversion meaningfully lowers reoffending and channels people into treatment, then a law that systematically blocks access could trade long-term public safety for a short-term illusion of control.

That said, the critics’ case is strongest as a warning about policy design, not as a refutation of AB 46’s core facts. The record supplied here does not include an official statewide audit proving the 40% recidivism rate cited by Sacramento County District Attorney Anne Marie Schubert, nor does it provide primary data demonstrating that the new standards will in fact eliminate diversion statewide. The opposition therefore has a credible theoretical argument and an advocacy-driven empirical claim, but not a completed evidentiary record. The result is an honest tension: AB 46 is clearly more restrictive, but the degree to which it will suppress legitimate treatment placements remains a question that only post-enactment data can settle.

How the law fits California’s larger pattern

AB 46 sits squarely inside a familiar California cycle. The state expands a therapeutic alternative to incarceration; a few high-profile failures follow; political pressure mounts; lawmakers narrow eligibility and restore judicial discretion. That pattern is neither novel nor unique to mental health diversion. It is one of the recurring rhythms of criminal justice reform across the United States, where the public accepts leniency in principle until a shocking case makes the costs visible. The pressure then shifts from mercy to proof: prove the defendant is safe, prove the treatment plan is sound, prove the diagnosis is current, prove the risk is low enough to justify release.

Once that burden changes, the policy changes with it. Mental health diversion was built on the premise that some defendants can be stabilized and rehabilitated more effectively outside the jail setting; AB 46 reasserts the older premise that not every clinical need outweighs the state’s obligation to prevent harm. That does not make the reform irrational. It does, however, make it more punitive than the original diversion model. The statute’s expanded risk language, five-year diagnosis rule, and added exclusions all point in the same direction: fewer automatic doors into treatment, more screening, more courtroom discretion, and more room to keep defendants in custody when judges think community placement is too risky.

What to watch next

The real measure of AB 46 will not be the rhetoric around its passage; it will be its downstream effects. Three questions matter most. First, how many defendants who would previously have received diversion are now rejected under the new public-safety standard? Second, does the narrower eligibility scheme reduce serious reoffending, or does it mostly keep more mentally ill defendants in jail without improving outcomes? Third, do counties build the kind of tracking and accountability infrastructure that would let policymakers judge whether the reform is working?

Those are not abstract questions. They determine whether AB 46 becomes a durable model for safer diversion or simply another episode in the long American habit of confusing narrower eligibility with better policy. If the state wants the public to trust mental health diversion, it needs more than a tougher standard; it needs evidence that the standard is actually sorting cases well. Until that evidence is public, AB 46 will remain what most such reforms become in practice: a compromise forged under pressure, defended as common sense, and judged in the end by its outcomes rather than its slogans.
