California's Retreat on Mental Health Diversion: A Dangerous Step Backward for Justice and Liberty

The Facts of the New Law

Governor Gavin Newsom has signed into law a fundamental change to California’s approach to mental health in the criminal justice system. The legislation, which passed the state legislature overwhelmingly, alters the standard judges must use when considering a “mental health diversion.” Since 2018, California policy directed judges to grant diversion for most crimes if a qualifying mental health diagnosis was a significant factor in the offense and the accused would “not pose an unreasonable risk of danger to public safety.” This allowed individuals to avoid incarceration by entering community-based treatment programs, with successful completion often leading to dismissed charges.

The new law flips this presumption. Now, judges are instructed to consider whether allowing community treatment would “endanger public safety,” defined specifically as increasing the likelihood of physical injury or serious danger to others. This represents a significant tightening of the criteria, shifting the legal burden and giving judges far more discretion to deny diversion.

The Context and Stated Rationale

This policy shift did not occur in a vacuum. It comes amid heightened public and political focus on crime, homelessness, and public disorder in California and across the nation. The bill’s author, Assemblymember Stephanie Nguyen (D-Elk Grove), argued the previous standard essentially forced judges into decisions with which they were uncomfortable, potentially compelling them to grant diversion even when they believed it was inappropriate. Supporters, prominently including state police unions and law enforcement groups, pointed to specific cases where individuals released on diversion were later arrested for other serious offenses. Their core argument is that the change empowers judges to make more nuanced decisions that prioritize community safety.

Governor Newsom echoed this in a statement, saying, “California believes treatment and accountability go hand in hand. We are proud to preserve mental health diversion for people who can benefit from it while ensuring judges have the discretion they need to protect victims, safeguard communities, and make decisions based on the full picture before them.”

The Opposition’s Case

The bill faced opposition from civil rights and human rights organizations, most notably the Ella Baker Center for Human Rights. Opponents argue this change represents a conservative, reactionary shift in judicial philosophy. They contend it uses outlier, high-profile cases to justify denying a broad spectrum of eligible defendants the mental health treatment they desperately need. Furthermore, they highlight that diversion programs serve as a crucial counterweight to systemic issues like over-policing and the disproportionately high incarceration rates of people of color. By allowing convictions to be wiped from records, these programs enable individuals to seek housing, education, and employment, breaking cycles of poverty and recidivism. Removing this option, they warn, eliminates needed flexibility and represents a major step backward.

A Betrayal of Fundamental Principles

This law is not a minor policy adjustment; it is a profound betrayal of the principles of a just, free, and humane society. Framed as a necessary measure for public safety, it instead institutionalizes a preference for punishment over healing and cages over care. The change from “not pose an unreasonable risk” to a mere potential to “endanger public safety” is a legalistic sleight of hand that guts the intent of the original diversion program. It replaces a standard designed to grant liberty and treatment with one designed to find reasons for denial.

The rhetoric from supporters is deeply concerning. Assemblymember Nguyen’s claim that the old system meant judges were “forced” to grant diversion “That’s not justice” inverts the very purpose of the diversion framework. The 2018 law was a deliberate policy choice to force the system to consider treatment first for those whose crimes were significantly linked to mental illness. It was a check on the system’s historic, and often discriminatory, reflex to incarcerate. To call this compulsion toward compassion “unjust” is to reveal a carceral mindset that views liberty as a threat to be managed, not a right to be protected.

Governor Newsom’s statement that “treatment and accountability go hand in hand” is a hollow platitude when the practical effect of his signature is to sever that connection for countless individuals. True accountability is not synonymous with imprisonment. For someone with a serious mental illness, real accountability can—and often does—mean successfully completing a rigorous treatment program, making amends, and rebuilding their life. This law suggests the state believes the only meaningful accountability occurs behind bars, a belief that is both cruel and counterproductive.

The Chilling Effect on Liberty and Equity

The discretionary power handed to judges is a double-edged sword that will likely fall hardest on the most vulnerable. Without the clearer, more defendant-friendly standard of the 2018 law, decisions will become more subjective and more susceptible to the implicit biases that plague our justice system. When a judge is told to ponder whether someone might “endanger public safety,” the safest bureaucratic and political choice is nearly always to say yes and deny diversion. This creates a chilling effect that will see fewer people granted this lifeline, regardless of their actual suitability.

This has dire implications for racial equity. As opponents rightly note, diversion programs are a tool to mitigate the devastating impacts of over-policing in communities of color. By making diversion harder to obtain, this law will disproportionately funnel more Black and Brown individuals with mental health conditions into California’s prisons, perpetuating cycles of trauma and disenfranchisement. It is a policy choice that will exacerbate existing inequalities under the guise of neutral “public safety.”

The False Promise of Safety

Supporters point to rare, tragic cases of re-offending to justify this wholesale change. This is a classic and dangerous political tactic: using fear and anecdote to dismantle systemic solutions. No system, carceral or therapeutic, can guarantee zero risk. But study after study shows that properly funded and implemented community-based treatment for mental illness is more effective at reducing long-term recidivism than incarceration. Prisons are warehouses of despair that often exacerbate mental health crises. By choosing to incarcerate more people who need treatment, California is arguably making its communities less safe over the long term, creating more traumatized, untreated individuals who will eventually be released without having received the help they needed.

Public safety is not advanced by reflexively locking away sick people. It is advanced by addressing the root causes of behavior. This law abandons that logic in favor of a simplistic, politically expedient “toughness” that comforts the fearful but fails the vulnerable.

A Call to Defend Smart Justice

As defenders of democracy, the Constitution, and human dignity, we must sound the alarm. The Bill of Rights exists to protect the individual from the overwhelming power of the state, a protection that is most crucial for those accused of crimes and those suffering from illness. This law weakens those protections. It expands the state’s power to incarcerate by narrowing a critical escape valve from the penal system.

California had begun to model a more intelligent, compassionate, and effective approach to the intersection of mental health and justice. This law represents a retreat from that model, driven by fear rather than evidence. It is a victory for the carceral lobby and a devastating loss for every Californian who believes in redemption, rehabilitation, and the fundamental right to treatment over punishment.

Our commitment to liberty and justice for all is tested not when we lock away the so-called “dangerous,” but when we extend mercy and help to those society deems undeserving. This law fails that test. We must continue to advocate for policies that see the humanity in every person, that treat mental illness as a public health challenge, and that recognize that a just society is measured by how it treats its most vulnerable members, not by how many cages it fills. The fight for true justice and smart, humane policy in California is far from over.
