AB 1535 revises the statutory definitions used in California's hate-crime law. Its headline change is to define “political affiliation” as a protected characteristic — covering party membership and endorsements of parties, politicians, or platforms — and to clarify several related terms such as “association with,” “victim,” and the causation standard used to prove bias motivation.
The bill is mainly definitional: it broadens what counts as association (including presence on premises tied to a protected group), declares certain definitions (disability, nationality) to reflect existing case law, and restates that bias need only be a substantial factor — not the sole cause — of an offense. For prosecutors, law enforcement, institutions, and political actors, those textual changes affect charging, evidence-gathering, reporting, and potential constitutional friction around political expression.
At a Glance
What It Does
AB 1535 amends the hate-crime definitions in California law by adding “political affiliation” as a protected characteristic and by expanding definitions for “association with,” “victim,” and causation. Several other definitions (disability, nationality, gender, religion, race/ethnicity, sexual orientation) are clarified or restated as declaratory of existing law.
Who It Affects
Prosecutors and defense attorneys who handle bias-motivated crimes; law enforcement agencies required to investigate and report hate crimes; political organizations, campaign offices, and individuals targeted for political beliefs; campuses, houses of worship, libraries and other institutions that may be named as victims.
Why It Matters
By listing political affiliation explicitly, the statute signals prosecutors and police to consider political bias as a basis for enhancements or hate-crime charges — a change with immediate operational implications and potential First Amendment questions about when political disagreement crosses into criminal bias.

What This Bill Actually Does
AB 1535 is not a new crimes-and-penalties package; it rewrites the dictionary used to apply California’s hate-crime law. The bill inserts a clear definition of “political affiliation” to cover belonging to a party and endorsing parties, politicians, or platforms, which means incidents motivated by those political ties can be treated as bias-motivated under the statute.
It also enlarges the statutory idea of “association with” a protected group to include being on or near premises tied to that group — a civilian, venue, or building associated with a protected characteristic can be treated as a lawful target.
Several definitions are explicitly labeled declaratory of existing law. The bill restates that “disability” includes both mental and physical disabilities as already defined in Government Code section 12926, and that “nationality” encompasses country of origin and immigration status.
It likewise clarifies that “gender” includes identity and expression, and that “religion” covers agnosticism and atheism. Those restatements are likely meant to reduce ambiguity in prosecutions and reporting without changing case law.On causation, AB 1535 spells out that “in whole or in part because of” means bias must be a cause-in-fact and a substantial factor in bringing about the offense, and that it need not be the main motive — language tied to California precedent.
Finally, the bill expands who counts as a “victim” to expressly include entities and locations (community centers, offices, libraries, schools, etc.), which affects who can be listed on reports and considered for hate-crime protections.Taken together, these changes shift how investigators and prosecutors spot, document, and justify bias-motivated charges: they give political targets and institutions clearer standing under the statute, but they also raise practical and constitutional questions about proof, proximity-based targeting, and the line between protected political speech and criminal bias.
The Five Things You Need to Know
The bill adds “political affiliation” as a protected characteristic, defined to include party membership and endorsement of a party, politician, or their platform.
It expands the meaning of “association with” to include being on premises owned, rented by, or adjacent to entities identified with a protected characteristic.
The bill clarifies the causation standard: bias must be a cause-in-fact and a substantial factor — it need not be the main motive — and cites controlling California precedent.
Several terms (disability and nationality) are declared to reflect existing law, linking the statute explicitly to Government Code §12926 and prior case law.
The statutory definition of “victim” is broadened to expressly include organizations and places (community centers, schools, libraries, offices, etc.), not only individuals.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Expanded definition of “association with” protected groups
Subsection (a) retools the phrase “association with a person or group with one or more of these actual or perceived characteristics” to include advocacy, identification, or being on premises owned, rented, or adjacent to entities identified with protected characteristics. Practically, that means prosecutors can point to a person’s presence at a venue associated with a protected group as evidence of bias motivation; it narrows the gap between attacking an individual and attacking their community site.
Disability defined as inclusive and declaratory
Subsection (b) restates that “disability” includes mental and physical disabilities as defined in Government Code §12926, and clarifies it covers temporary and permanent conditions. The bill marks this definition as declaratory — the text signals lawmakers intend no substantive change but want to remove arguments that the statute’s disability coverage is narrower than state civil-rights law.
Gender includes identity and expression
Subsection (c) defines gender to include sex, gender identity, and gender expression; it explicitly defines “gender expression” as appearance and behavior regardless of sex assigned at birth. For investigators and prosecutors, the provision reduces ambiguity about whether nonconforming gender presentation counts as a protected trait for motive analysis.
Causation standard: ‘in whole or in part because of’
Subsection (d) clarifies that bias must be a cause-in-fact and a substantial factor in the offense, while not needing to be the sole motive. By anchoring the definition to In re M.S. and People v. Superior Court (Aishman), the bill codifies a widely used but sometimes litigated proof standard, which affects how prosecutors frame intent and motive evidence in charging and at trial.
Political affiliation added as protected characteristic
Subsection (f) is the bill’s substantive hook: it defines “political affiliation” to cover belonging to a political party and endorsing a political party, politician, or platform. That language brings politically motivated attacks explicitly within the reach of hate-crime law and requires prosecutors to consider political bias when determining enhancements or separate bias-based offenses.
Victim definition expanded to include places and organizations
Subsection (j) lists entities — community centers, educational facilities, offices, meeting halls, places of worship, libraries, public agencies, and similar institutions — as victims. The change makes it explicit that bias against an institution or site can satisfy the statute’s victim element, which alters reporting categories and may increase institutional claims of hate-crime victimhood.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Individuals targeted for their political affiliation — they gain an explicit statutory basis for classifying attacks as bias-motivated and for prosecutors to pursue hate-crime enhancements.
- Organizations and venues (campaign offices, community centers, libraries, houses of worship) — the expanded victim definition gives institutions clearer standing in reporting and charging decisions.
- Prosecutors and law enforcement — clearer statutory definitions reduce pleading ambiguity and guide investigative focus on motive tied to political beliefs or association.
Who Bears the Cost
- Law enforcement agencies and county district attorneys — they will face training, policy updates, and evidence-collection costs to implement the broadened definitions and track politically motivated incidents.
- Political activists and campaign organizations — their rallies, signs, or endorsements could be used as evidence of affiliation, increasing the risk that heated political acts are investigated as bias-motivated crimes.
- Defense counsel and courts — courts may see increased First Amendment litigation testing the boundary between criminal bias and protected political expression, adding litigation costs and complexity.
Key Issues
The Core Tension
The bill pits two defensible objectives against each other: protecting people and institutions from violence motivated by political identity, and preserving robust political expression and dissent. Drawing a workable line — where partisan antagonism becomes criminal bias rather than ordinary political debate — is the central, unresolved dilemma.
AB 1535 tightens statutory language but leaves several operational and constitutional questions unresolved. The “political affiliation” definition is broad: by covering endorsements of politicians and platforms, it can sweep in commonplace political speech and campaign activity when used as evidence of affiliation.
That raises evidentiary and Free Speech concerns about whether partisan hostility or routine political disagreement should trigger hate-crime treatment. Prosecutors will need guidance on distinguishing protected advocacy from bias-motivated violence.
The expanded “association with” language — including presence on premises owned or adjacent to an entity tied to a protected characteristic — invites edge cases. A person attacked near a political campaign office or a library associated with a movement could be treated as a bias victim, but proximity-based inferences risk overreach and factual disputes about the attacker’s motivation.
While the bill reaffirms a substantial-factor causation test, proving bias-in-fact remains fact-intensive and resource-heavy. Implementation will depend on new training, model policies, and likely litigation over how the statute interacts with the First Amendment and over what counts as sufficient evidence of political bias.
