SB 258 revises California Penal Code section 261 by changing how the law treats victims with mental disorders, developmental disabilities, or physical disabilities in rape prosecutions and by clarifying several enumerated circumstances that constitute rape. The bill makes clear that a disability alone does not create a presumption of incapacity to consent; instead the prosecutor must prove that a disability rendered the victim incapable of giving legal consent.
It also requires courts to consider specified mitigating measures and voluntary supports when assessing capacity and enumerates detailed definitions for unconsciousness, fraud-based consent, threats, and duress.
This matters because the bill shifts the evidentiary landscape in sexual-assault cases involving disability: it elevates the prosecutor’s burden with respect to capacity while inserting specific rules about what evidence (supports, mitigating measures, conservatorship status) may be considered. The changes will affect charging decisions, evidentiary strategy, records handling by service providers and agencies, and how judges instruct juries about consent and incapacity.
At a Glance
What It Does
Amends the statutory definition of rape to: prohibit presuming a person is unable to consent solely because of a disability; require the prosecution to prove incapacity as an element; require consideration of mitigating measures and voluntary supports; and clarify several modes of nonconsensual intercourse (force, intoxication, unconsciousness, fraud, threats, and misuse of public-official authority).
Who It Affects
Prosecutors, defense counsel, judges, and juries in sexual-assault cases; people with mental disorders, developmental or physical disabilities and their caregivers; conservatorship and support-service providers whose records or testimony may become evidence; and law enforcement and county agencies responsible for investigation and disclosure.
Why It Matters
The bill both protects the autonomy of people with disabilities by avoiding categorical incapacity findings and raises practical evidentiary hurdles for prosecutions—altering how capacity is proved, what records and supports matter, and how fraud- and threat-based scenarios are litigated.

What This Bill Actually Does
SB 258 rewrites how California’s rape statute treats consent when a victim has a mental disorder, developmental disability, or physical disability. The key change is a prohibition on treating a diagnosis or disability as a stand-alone presumption that a person cannot consent.
Instead, the law requires the prosecutor to establish, as an element of the offense, that the disability actually rendered the alleged victim incapable of giving legal consent at the time of the intercourse. The provision expressly says that the mere existence of a conservatorship under the Lanterman–Petris–Short Act or the absence of certain voluntary supports does not relieve the prosecution of that burden.
The bill directs courts to consider two categories of evidence when assessing capacity: mitigating measures defined in Title 2 of the California Code of Regulations (Section 11065 as it existed on January 1, 2025) and voluntary supports described in Welfare and Institutions Code Division 11.5 (with limited exceptions). That means whether a person used assistive technology, had communication supports, or received other individualized services can be part of the capacity analysis; those items become evidence that can cut for or against a finding of incapacity.
At the same time, SB 258 preserves other routes to prosecute—if the facts fit a different paragraph of the statute (force, intoxication, fraud, etc.), the prosecution may proceed under that theory.Outside the disability-focused changes, the bill sharpens several existing rape definitions. It spells out what “unconscious of the nature of the act” covers (including being asleep, not aware that an act occurred, or being deceived about the essential characteristics of the act through fraud).
It creates two fraud-based categories: fraud in fact (the victim is unaware an act occurred) and fraudulent representation that a sexual act served a professional purpose when it did not. SB 258 also clarifies that threatening future retaliation (kidnap, extreme pain, serious bodily injury, or death) or threatening to use the authority of a public official (arrest, incarceration, deportation) can constitute rape—importantly, the accused need not actually be a public official for the threat to qualify.Finally, the bill adds definitional precision for evidentiary assessment: it defines “duress” as threats sufficient to coerce a reasonable person, instructs that age and relationship are relevant factors, and sets out two alternative legal meanings of incapacity (unable to understand the nature of the act or unable to act freely and voluntarily).
Those definitions matter because they guide what types of expert, medical, or support-provider testimony will be material at trial and how judges will gate and shape jury instructions.
The Five Things You Need to Know
The bill bars any presumption that a mental disorder, developmental, or physical disability by itself makes a person unable to consent; the prosecution must prove incapacity as an element of the crime.
Evidence of mitigating measures (as defined in Title 2 CCR §11065 as it existed on Jan 1, 2025) and voluntary supports (Welfare & Institutions Code Division 11.5, except subsections (a) and (b) of §21000) must be considered when assessing capacity.
The statute explicitly treats two kinds of fraud-based incapacity as rape: fraud in fact (victim unaware the act occurred) and fraudulent representation that the penetration served a professional purpose when it did not.
A threat to use the authority of a public official to arrest, incarcerate, or deport a victim qualifies as a rape ground even if the perpetrator is not actually a public official; the victim’s reasonable belief suffices.
The definitions add that duress depends on the totality of the circumstances (including the victim’s age and relationship to the defendant) and that incapacity can mean either inability to understand the act or inability to act freely and voluntarily.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
No presumption of incapacity; prosecutorial burden
This subsection states that a diagnosis or disability alone cannot create a legal presumption that a person lacked the capacity to consent. If the alleged victim has a mental disorder or developmental/physical disability, the prosecution must prove that the disability rendered the victim incapable of giving legal consent at the time of the intercourse. The provision also says that the mere existence of a conservatorship under the Lanterman–Petris–Short Act, or lack of certain voluntary supports, does not substitute for that proof—so conservatorship status no longer functions as an automatic proxy for incapacity.
Mandatory consideration of mitigating measures and voluntary supports
The statute requires courts to consider (i) mitigating measures as defined in Title 2 CCR §11065 (as of Jan 1, 2025) and (ii) voluntary supports described in WIC Division 11.5 (with limited exceptions) when determining whether a person was capable of consenting. Practically, that imports records and testimony about assistive devices, communication supports, or other accommodations into the capacity inquiry and makes service plans and support documentation potentially central evidence.
Force, duress, and intoxication-based incapacity
These paragraphs preserve and clarify traditional rape grounds: intercourse by force, violence, duress, menace, or fear of immediate bodily injury; and intercourse where the victim was prevented from resisting by intoxicants or anesthetic substances if the accused knew or reasonably should have known of that condition. The language codifies that the defendant’s knowledge (or what they reasonably should have known) about the victim’s condition is a material inquiry, which will often require investigation into the timeline and the accused’s conduct.
Expanded 'unconscious of the nature of the act' definitions, including fraud
Subsection (4) breaks unconsciousness into multiple, distinct situations: being asleep or unconscious; not being aware that the act occurred; not being aware of essential characteristics of the act because of fraud in fact; and not being aware because the perpetrator falsely represented a sexual penetration as serving a professional purpose. Distinguishing fraud in fact from professional-purpose fraud matters for how prosecutors and defense counsel frame expert testimony, and it creates separate factual hooks for charging and jury instruction.
Artifice, future-retaliation threats, and misuse of public-official authority
These paragraphs cover situations where a victim submits because they are deceived into believing the actor is someone else, where the actor threatens future retaliation (kidnap, extreme pain, serious bodily injury, or death) and there is a reasonable possibility the threat will be carried out, and where the actor threatens to use public-official authority to arrest, incarcerate, or deport the victim (with the victim’s reasonable belief sufficing). The public-official clause defines 'public official' by the kind of authority at issue and does not require the perpetrator actually to hold any office.
Key definitions: duress, incapacity, menace
Subsection (b) supplies working definitions for duress (threats sufficient to coerce a reasonable person, with totality factors such as age and relationship), incapacity (two alternative prongs: inability to understand the nature of the act or inability to act freely and voluntarily), and menace (a declaration or act showing an intent to harm). These definitions steer what evidence—medical, expert, or testimonial—will be admissible and relevant in proving elements at trial.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- People with mental disorders, developmental, or physical disabilities — the statute prevents categorical findings of incapacity and affirms autonomy by requiring individualized proof rather than presumptions tied to diagnosis or conservatorship status.
- Defendants in sex-assault prosecutions where the alleged victim has a disability — they gain a clearer legal barrier to convictions based solely on a victim’s diagnosis, forcing prosecutors to prove incapacity factually.
- Courts and juries — the law supplies explicit definitions and a checklist of considerations (mitigating measures, voluntary supports, conservatorship caveats) that can reduce ambiguity in jury instructions and evidentiary rulings.
- Disability service providers and support coordinators — their records, plans, and testimony gain legal relevance because documented supports can be evidence that a person could consent.
- Civil-rights and due-process advocates — the change advances a non-discriminatory approach to capacity assessments, aligning criminal law with supported-decision-making principles.
Who Bears the Cost
- Prosecutors and district attorney offices — the requirement to prove incapacity as an element will increase investigative needs (experts, records subpoenas, forensic and medical evidence) and may reduce charging or conviction rates in some cases.
- Victims with disabilities — while the law protects autonomy, victims may face higher evidentiary hurdles and intrusive inquiries into their supports, services, and functional abilities, which can be retraumatizing.
- County and state agencies and providers — agencies that maintain records of supports (service plans, assessments, conservatorship files) will see more subpoenas and privacy requests, imposing administrative and compliance costs.
- Courts and judges — trial management and jury instruction will become more complex, potentially lengthening trials and increasing demand for expert witnesses on capacity and supports.
- Law enforcement — officers will need additional training to investigate capacity-related facts, document supports, and work with service providers in ways that protect victims’ privacy while preserving evidence.
Key Issues
The Core Tension
The bill pits the principle of non‑discrimination and individual autonomy for people with disabilities—refusing to treat diagnosis or conservatorship as dispositive—against the practical need to protect and prosecute victims who were in fact incapable of consenting; enforcing individualized proof protects rights but makes successful prosecution harder and invites intrusive evidentiary disputes.
The statute attempts to thread two difficult policy goals: it protects the autonomy of people with disabilities by refusing to treat diagnosis alone as determinative of consent, while also preserving multiple statutory routes to prosecute nonconsensual intercourse. That approach creates implementation challenges.
Prosecutors must prove a counterfactual—whether a disability rendered a person incapable at a particular moment—often years after the fact. That inquiry will rely heavily on contemporaneous medical records, support plans, assistive-technology logs, and expert testimony; those sources vary in availability and quality and raise privacy concerns.
The requirement to 'consider' mitigating measures and voluntary supports imports agency records and third-party documentation directly into criminal trials. Service providers will face more subpoenas and cross-examinations about individualized supports, and courts will have to develop standards for how much weight to give those measures.
The bill’s exceptions around particular subdivisions of the Welfare & Institutions Code and the freeze-date reference to a regulatory definition (Title 2 CCR §11065 as of Jan 1, 2025) create additional interpretive questions: which versions of the regulation apply over time, how to treat subsequent changes to support definitions, and how to reconcile competing privacy statutes with discovery obligations.
Another unresolved problem is strategic behavior: defendants may try to use evidence of supports to argue capacity even where the supports were limited or not functioning at the moment of the offense; conversely, prosecutors may tie themselves in evidentiary knots proving incapacity while alternative statutory theories (force, fraud, threats) might be easier to litigate. Finally, the law’s definitional clarifications (for unconsciousness, fraud, and public-official threats) will require courts to delineate factual lines in ways that could produce inconsistent outcomes across jurisdictions until higher-court guidance accumulates.
