Courts deny mental health diversion in California either because a defendant fails the statutory eligibility test or, more often, because the judge finds the defendant unsuitable under the public safety standard now reshaped by AB 46. If you are facing a denial or preparing a petition, the fastest way forward is to talk with your attorney and pull together a qualified expert opinion and a court-ready treatment plan before the hearing, using resources such as Penal Code §1001.36, AB 46, and firms like Executive Treatment Solutions that build court-compliant documentation.
TL;DR:
- Eligibility requires a recent diagnosis within five years, directly linking the disorder to the offense and affirming the treatment plan’s clinical appropriateness.
- Court suitability hinges on concrete risk mitigation strategies and a detailed, accepted treatment plan, not just meeting statutory criteria.
- Dismissals often occur when treatment proposals are generic, unaccepted, or lack clear connections between diagnosis and safety measures.
- Under AB 46, courts now demand documented risk assessment and explicit reasons for denial to avoid vague safety concerns.
- Preparing a comprehensive, multidisciplinary treatment plan with regular monitoring and a strong expert opinion significantly improves chances of approval.

Statutory eligibility under PC 1001.36 and PC 1001.95
Before a judge ever weighs suitability, the court checks whether a defendant meets the statutory floor. Under Penal Code §1001.36, mental health diversion requires a diagnosed mental disorder, a connection between that disorder and the charged conduct, and a qualified mental health expert’s opinion that the disorder played a significant role in the offense. The defendant must also agree to comply with treatment and waive certain speedy trial rights, and the petition must be filed and heard before the case reaches adjudication.
Misdemeanor cases have a separate track. Penal Code §1001.95 lets a judge grant diversion on their own initiative, even over a prosecutor’s objection, for up to 24 months. This flexibility comes with hard boundaries. The statute excludes offenses that require sex offender registration, along with domestic violence, stalking, and DUI charges, regardless of how sympathetic the underlying facts might be.
Several practical exclusions and timing rules trip up otherwise strong petitions:
- Offenses requiring sex offender registration are categorically excluded from misdemeanor diversion under PC 1001.95.
- Domestic violence, stalking, and DUI charges cannot be diverted under the misdemeanor statute even when the defendant otherwise qualifies.
- A petition filed after adjudication is generally too late, since the window closes once the case moves past that stage.
- Diversion length tops out at two years for felony mental health diversion and one year for misdemeanor mental health diversion, with the misdemeanor judicial diversion track allowing continuances up to 24 months.
For readers who want the fuller mechanics of how mental health diversion works from filing to dismissal, our primer on the mental health diversion program walks through the process in more depth, and a separate breakdown of offenses excluded from pretrial diversion covers the exclusion categories in detail. Meeting every eligibility box does not guarantee a grant. It only earns the defendant a seat at the suitability hearing, which is where most petitions actually succeed or fail.
Why courts deny diversion even when a defendant looks eligible
Eligibility is a checklist. Suitability is a judgment call, and that distinction explains most denials. Once a judge confirms the statutory criteria are met, the real fight shifts to whether the proposed treatment plan and the defendant’s history persuade the court that community treatment will not create a public safety problem.
Several recurring patterns show up in denied petitions:
- The treatment plan is generic or recycled from a prior unsuccessful attempt, with no explanation of what will be different this time.
- No treatment provider has actually accepted the defendant, leaving the plan aspirational rather than concrete.
- The expert opinion is thin: it states a diagnosis without clearly tying the disorder to the offense conduct.
- The defendant’s criminal history includes serious violence that the plan does not directly address through supervision or risk mitigation.
- Victim concerns remain unresolved on the record, and the defense offers nothing to counter them.
Courts commonly reject petitions that simply repeat a treatment approach that already failed once, without showing how a new plan changes the supervision level or adds modalities the prior attempt lacked. Judges want to see closer monitoring, different clinical methods, or concrete safeguards, not the same plan with a new date on it.
Pro Tip: If a prior treatment episode did not stick, lead your new petition with exactly what changed, tighter monitoring, a new provider, added therapy modalities, rather than asking the court to trust the same plan a second time.
Appellate courts have made clear that safety-based denials cannot rest on generalizations. Recent case law and legal commentary indicate that a denial grounded in vague safety concerns, rather than specific facts tied to the record, is vulnerable on review, and reviewing courts expect the trial judge to point to substantial evidence rather than a hunch or a category of offense. That standard cuts both ways: it protects defendants from boilerplate denials, but it also means a well-documented, fact-specific denial is hard to overturn.
AB 46 (2026): what changed and what it means for denial decisions
On June 29, 2026, Governor Newsom signed AB 46, which revised the mental health diversion statute in ways that directly affect how denials get written and defended. The bill requires courts to find that a defendant will not pose a “substantial and undue risk to the physical safety of another person” if treated in the community, language that replaces older, looser phrasing and gives judges a sharper standard to apply.
AB 46 also imposes a recent diagnosis requirement. The governor’s press release confirms the law now requires a diagnosis or rediagnosis within a recent period before the alleged offense, closing off petitions built on stale clinical records. This single change has already forced defense teams to budget time for a fresh evaluation before filing.
Beyond the risk standard and the diagnosis window, the revised law makes several other things explicit:
- The expert opinion must state that the proposed treatment plan itself is clinically appropriate, not just that a diagnosis exists.
- Judges must state their reasons for denial on the record, a requirement confirmed in the bill text and useful for any later appeal or reapplication.
- The public safety inquiry now centers on documented risk mitigation rather than the nature of the charge alone.
For defense counsel filing under the new framework, the checklist has grown: secure a diagnosis or rediagnosis within the five-year window, have the expert directly endorse the treatment plan’s clinical appropriateness, and build the risk-mitigation narrative into the plan itself rather than leaving it implied.
What makes a persuasive treatment plan and expert opinion
Judges are not evaluating good intentions. They are evaluating a document, and that document either gives them enough to say yes or it does not. County-level guidance, including the Solano County mental health diversion procedural guidelines, lays out what a workable plan actually contains.
A plan that survives scrutiny typically includes:
- A signed statement from the treatment provider confirming acceptance of the defendant, not just a referral.
- Specific modalities, such as medication management, DBT or CBT, and substance abuse treatment where relevant.
- A monitoring and testing schedule that matches the risk level the offense presents.
- Measurable goals with a defined reporting cadence, often monthly or quarterly depending on the county.
- A long-term aftercare component showing the plan extends past the minimum diversion period.
The expert opinion carries equal weight. It needs to connect the diagnosed disorder to the specific conduct at issue, affirmatively state that the proposed plan is clinically appropriate, and address how the plan mitigates the risk factors the court will be weighing under AB 46’s new standard. An opinion that only recites a diagnosis without addressing the offense or the plan’s adequacy invites a denial almost by default.
Pro Tip: Ask the evaluating clinician to write one paragraph specifically linking the diagnosis, the offense conduct, and the proposed plan’s risk mitigation, judges look for that connective tissue and often flag its absence in denials.
Documentation quality matters as much as content. Legible reports, clear provider credentials and contact information, and a realistic reporting schedule all signal to the court that the plan will actually be monitored, not just filed and forgotten. Our guide to PC 1001.36 procedures covers what a complete submission looks like in practice.
Procedural steps to request diversion and preserve your rights after a denial
Filing for diversion follows a defined sequence, and understanding each stage helps you know where a case can go wrong and how to fix it.
- File the petition along with the proposed treatment plan before the case reaches adjudication, since filing after that point generally forecloses the option.
- Expect a prima facie hearing first, where the court checks whether the statutory eligibility criteria are even met.
- If the threshold is satisfied, the case moves to a suitability hearing, where the court weighs the treatment plan, the expert opinion, and public safety.
- Present up-to-date expert declarations, written provider acceptance, a specific monitoring plan, and, where relevant, prior treatment records and witness offers of proof.
- Understand that pursuing diversion generally means waiving speedy trial rights for the diversion period.
When a petition is denied, the response matters as much as the filing itself. Under AB 46, the judge must state reasons for the denial on the record, so insist on that if it does not happen automatically. Once you know the specific defect, whether it is a stale diagnosis, a thin expert opinion, or an unaccepted treatment plan, you can move to supplement the record or ask for a continuance to fix it rather than starting over. Preserving objections at this stage also protects your options if the case eventually heads to appeal. Our checklist for court-ready misdemeanor diversion documents offers a practical template for assembling the kind of record that holds up at this stage.
What happens after denial, and the alternatives worth considering
A denial does not end the case. It returns the matter to the standard criminal track, which means plea negotiations, trial preparation, or, in many instances, a renewed petition once the defects the court identified have been addressed.
Several alternative paths are worth exploring depending on the charge and the defendant’s circumstances:
- Misdemeanor judicial diversion under PC 1001.95 remains available for qualifying misdemeanors even when mental health diversion is denied or unavailable.
- Drug-related diversion under PC 1000 or Proposition 36 fits cases where substance use, rather than a qualifying mental health diagnosis, is the central issue.
- Veterans courts and other specialty court programs may apply where the defendant’s history includes military service or other qualifying circumstances.
- A conservatorship referral becomes relevant in the narrower set of cases involving grave disability, separate from the criminal diversion track entirely.
One protection applies across all of these paths: under AB 2297, a defendant’s inability to pay restitution because of indigence or a mental disorder is not a lawful basis for denying diversion. Courts can structure restitution around the defendant’s ability to pay, but they cannot use poverty itself as a gatekeeping device. For readers weighing misdemeanor alternatives specifically, our overview of how PC 1001.95 can clear a case covers that route in more detail.
Why documentation quality decides more diversion cases than the law itself
Most of the advocacy work in a diversion case happens before anyone sets foot in a courtroom. Some firms build the kind of documentation judges say they are missing when they deny a petition: clinical assessments tied directly to the offense, treatment plans a provider has actually agreed to run, and progress reports that arrive on schedule instead of the night before a hearing. That coordination with defense counsel, rather than any single legal argument, is usually what separates a granted petition from a denied one.
Judges evaluating suitability under AB 46’s tighter standard are looking for a paper trail that anticipates their concerns before they have to ask. A plan that is multidisciplinary, drug testing, therapy, monitoring, and reporting working together, reads as a system rather than a promise. Speed matters too, since a five-year diagnosis window and a prima facie hearing on the calendar do not leave much room for a treatment plan assembled at the last minute.

How Executive Treatment Solutions supports a diversion petition
Building a treatment plan that satisfies a judge under AB 46’s standard takes more than good intentions. It takes an assessment, a provider willing to sign on, a testing schedule, and someone tracking all of it against the court’s deadlines. Some providers handle that work by coordinating with defense attorneys so the paperwork matches what the statute and local procedural guidance actually require.
The services map closely onto what PC 1001.36 and AB 46 now expect from a petition:
- Pretrial mitigation and court advocacy to package the case for a suitability hearing.
- Mental health assessments and treatment planning aligned with the five-year diagnosis rule.
- Drug and alcohol screening with documentation courts can rely on.
- Case management and progress reporting on a schedule the court sets.
- Monitoring services, including coordination for GPS or house arrest where required.
| Service | What it addresses |
|---|---|
| Mental Health Diversion Programming | Provider acceptance, treatment modalities, and clinical documentation for the petition |
| Case Management | Ongoing coordination between treatment providers and defense counsel |
| Monitoring Services | Testing and supervision records courts expect for risk mitigation |
If you are preparing a petition or responding to a denial, the next step is a conversation with your attorney about whether a structured, professionally documented plan changes your odds. You can review Mental Health Diversion Programming or start with Pretrial Mitigation & Court Advocacy to see how a court-ready packet comes together.

FAQ
Why would diversion be denied?
Diversion is usually denied for one of two reasons: the defendant does not meet the statutory eligibility criteria under PC 1001.36, or the court finds the defendant unsuitable because the treatment plan is weak, unaccepted by a provider, or does not adequately address public safety risk. Most denials happen at the suitability stage rather than the eligibility stage.
What is the new law for mental health diversion in California?
AB 46, signed on June 29, 2026, requires courts to find that a defendant will not pose a “substantial and undue risk to the physical safety of another person” and mandates a diagnosis or rediagnosis within five years of the alleged offense. It also requires judges to state their reasons for denial on the record.
Can you go out of state on diversion?
Diversion agreements generally require the defendant to remain available for court-ordered treatment, testing, and progress reporting, which makes extended out-of-state travel difficult without prior court approval. Any travel request should go through your attorney so the court can confirm it will not interrupt the monitoring schedule the treatment plan requires.
How many times can you use a diversion program?
The law does not set a fixed number of uses, but courts weigh prior diversion history heavily when deciding suitability for a new petition, especially if an earlier attempt was unsuccessful. A repeat petition needs to show what has changed, whether that is a new provider, added modalities, or closer supervision, to overcome that scrutiny.
