AB 1776 changes the Cartwright Act’s statutory definition of a "trust" by removing the two-person requirement and defining a trust as a combination of capital, skill, or acts by one or more persons. The bill leaves the Act’s prohibited purposes and enumerated examples intact but expands the pool of conduct that can fall within the statute.
The practical effect is a wider scope for both civil and criminal enforcement under the Cartwright Act. That shift raises immediate compliance and enforcement questions—whether single-firm conduct, corporate internal arrangements, or sole proprietorship activity might now trigger criminal liability—and creates statutory interpretation issues likely to be litigated.
At a Glance
What It Does
The bill revises Business & Professions Code §16720 to broaden the statute’s reach so that the statutory concept of a "trust" can arise from conduct by a single legal actor as well as by multiple actors, while keeping the Act’s listed prohibited purposes and contractual examples unchanged.
Who It Affects
State and local prosecutors, in-house and outside counsel for California-based firms (including single‑entity firms and sole proprietors), trade associations, and competitors that bring private Cartwright Act suits are directly affected; industries with concentrated market players (healthcare, agriculture, tech, utilities) should pay particular attention.
Why It Matters
Expanding the definition shifts the legal baseline for what counts as unlawful coordination or market control in California, broadening the universe of potentially criminal conduct and increasing litigation and enforcement risk for entities that previously relied on solo-actor defenses or on the two‑party line in the existing law.

What This Bill Actually Does
The bill alters only one core element of the Cartwright Act: the numerical threshold embedded in the statutory definition of a "trust." By removing the explicit requirement that a "trust" be "by two" persons and authorizing the concept where acts, capital, or skill are combined by "one or more" persons, California law no longer confines the statute to conduct that involves more than one actor. The list of prohibited purposes—restricting trade, limiting production, preventing competition, fixing prices, and the variety of contractual arrangements in subsection (e)—remains unchanged.
That textual tweak has outsized consequences because the Cartwright Act operates both as a civil remedy vehicle (including private suits and damages under long‑standing state antitrust doctrine) and as a criminal prohibition. Prosecutors could interpret the amended definition to pursue unilateral conduct they view as anticompetitive—internal pricing policies, coordinated behavior inside a vertically integrated firm, or single‑firm strategies that previously fell outside the Act’s concerted‑action framing.
Conversely, defense counsel will press for narrow readings that preserve the historical concerted‑action core of antitrust law, so expect early litigation over statutory interpretation and legislative intent.The bill also includes the standard state‑mandated local program language and an explicit note that no reimbursement is required because the changes alter criminal definitions and penalties under existing constitutional and statutory guidance. Practically, the amendment does not itself change prescribed penalties or add new remedies in text, but it enlarges the set of facts that can expose an actor to the Act’s existing criminal and civil consequences, which in turn affects compliance programs, risk assessments, and enforcement priorities.For compliance officers and counsel, the immediate takeaway is to reassess activities previously viewed as unilateral or internal for potential exposure—pricing algorithms, exclusive dealing imposed unilaterally, and merger‑adjacent conduct deserve renewed scrutiny.
For prosecutors and civil plaintiffs, the amendment broadens pleading strategies but invites challenges that will test whether the statute can be read to criminalize single‑actor behavior without running afoul of federal antitrust principles and constitutional limits.
The Five Things You Need to Know
The bill amends Business & Professions Code §16720 to replace the statutory phrase requiring a combination "by two" persons with "one or more" persons, removing the explicit multi‑actor threshold.
All existing enumerated prohibitions and the subsection (e) contractual examples remain in place; the change is limited to the actor-count language, not the listed prohibited purposes.
The amendment increases the pool of conduct that can trigger Cartwright Act liability—criminally and civilly—because it potentially covers single‑actor or single‑entity conduct that was previously outside the statute’s text.
Section 2 declares that the state need not reimburse local agencies for costs because the bill changes criminal definitions or penalties, flagging a state‑mandated local program issue while denying reimbursement responsibility.
The bill does not amend penalty provisions or create new civil remedies in its text; it expands exposure by broadening the definition of actionable conduct, which will shift litigation and enforcement strategies.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Numeric threshold change for what constitutes a "trust"
This provision swaps the statutory qualifier that a "trust" be a combination "by two" persons with "one or more" persons. On its face that converts the definition from a persistently concerted‑action focused text into a formulation that can be read to encompass single‑actor conduct. Practically, that means prosecutors and private plaintiffs can argue the statute reaches conduct undertaken unilaterally by a single legal actor; defenders will press for readings that preserve a requirement of concerted or cooperative behavior drawn from common law and federal antitrust precedent.
Prohibited purposes retained
Subsections (a)–(d) keep the Cartwright Act’s classic list of forbidden ends—restrictions on trade, output suppression, competition prevention, and price‑fixing—unchanged. Because these substantive prohibitions remain intact, the amendment’s import is to broaden who can be said to have undertaken actions toward those ends, not to expand the list of proscribed ends themselves. That narrow drafting choice increases interpretive stakes (what does it mean for one person to ‘‘combine’’?) without altering the statute’s policy goals.
Contractual examples preserved
Subsection (e)’s four illustrative contractual restraints (no‑sale floors, price‑maintenance agreements, price‑establishing arrangements, and pooling of interests) are preserved verbatim. The retention of these examples means the courts will likely read the amendment through the lens of the Act’s traditional contract‑and‑combination framing, weighing whether a single actor can plausibly be said to "enter into" or "carry out" such agreements in the absence of multiple parties.
No reimbursement for local agencies; criminal‑definition carve-out
Section 2 states that the state need not reimburse local governments because the bill creates or changes a crime/infraction definition under California constitutional and Government Code standards. That language signals the Legislature’s position that the amendment affects criminal liability and that any local costs tied to enforcement stem from that change rather than a new policy mandate for local governments.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Consumers and small businesses harmed by monopolistic conduct — if prosecutors or private plaintiffs successfully apply the broader definition to previously hard‑to‑reach conduct, injured buyers or small competitors may gain an expanded path to relief.
- State and local prosecutors — the broadened definition gives prosecutors a wider statutory toolset to pursue alleged anticompetitive conduct without having to tie liability strictly to multi‑party agreements.
- Competitors and market entrants — firms that face exclusionary practices by a dominant single firm could gain new legal arguments to challenge unilateral conduct under state law.
Who Bears the Cost
- Single‑firm operators and sole proprietors — entities that previously relied on the absence of a second actor in §16720 will face new criminal and civil exposure, increasing compliance costs and legal risk.
- In‑house and outside counsel — companies must revisit compliance programs, procurement and pricing policies, and internal documentation to guard against novel Cartwright Act allegations.
- Local prosecutors and courts — broader statutory reach will increase investigation and prosecution decisions and litigation load, creating resource pressure even if the bill’s reimbursement language attempts to allocate fiscal responsibility to counties and cities.
- Industries with concentrated markets (healthcare, utilities, agriculture, big tech) — these sectors will likely see heightened enforcement focus and may incur operational costs to redesign practices that could be read as unilateral "combinations."
Key Issues
The Core Tension
The central dilemma is between strengthening antitrust enforcement by capturing more harmful conduct (including potentially exclusionary single‑firm behavior) and the risk of overcriminalization and legal uncertainty: expanding the statute’s reach aids victims and enforcers but may criminalize ambiguous unilateral business decisions, chill procompetitive conduct, and invite constitutional and federal‑preemption challenges.
The amendment’s force depends entirely on statutory interpretation. The text replaces a numeric threshold but leaves the Act’s prohibitions untouched, which creates a high‑stakes question for courts: can a single actor be a "combination" in any coherent legal sense?
If courts accept a single‑actor reading, the statute will sweep significantly wider; if courts require some form of concerted or collective action as a matter of construction, the practical change may be limited. That interpretive uncertainty will drive early litigation, creating a period of increased transactional and enforcement risk.
There is a real constitutional and federal‑law knot to untangle. Federal antitrust law (Sherman Act) and state Cartwright law have long been read in parallel; federal standards emphasize agreements or concerted action.
A Texas‑style or California‑state attempt to criminalize unilateral conduct risks preemption or at least doctrinal friction with federal law and creates due‑process and vagueness challenges—especially where the statutory language forces agencies to prove a defendant formed a "combination" without clear guidance on what that requires. Practically, businesses will respond by contracting more cautiously and retaining more counsel, while prosecutors must balance novel criminal exposure against the higher standards and consequences of criminal charges.
