The landscape of labor law in California has long been characterized by a persistent tension between state judicial interpretations and federal mandates, particularly regarding the enforcement of mandatory arbitration agreements. In a recent development that further complicates this environment, the California Court of Appeal issued a significant ruling in Phan v. Knight Sacramento SU Inc., _ Cal.Rptr.3d (2026). This decision underscores the rigorous scrutiny California courts apply to arbitration contracts and highlights the evolving standards of "unconscionability" that can render such agreements unenforceable. For California employers, the ruling represents the latest hurdle in what legal analysts frequently describe as a game of "Whack-A-Mole," where as soon as one legal barrier to arbitration is cleared by federal preemption, a new state-level defense emerges to take its place.
The Legal Framework: FAA Preemption vs. State Unconscionability
To understand the significance of Phan v. Knight Sacramento SU Inc., one must first look at the broader legal framework. The Federal Arbitration Act (FAA) of 1925 established a strong national policy favoring arbitration, requiring courts to enforce arbitration agreements according to their terms. The United States Supreme Court has repeatedly affirmed that the FAA preempts state laws or judicial doctrines that single out arbitration for disfavored treatment.
However, the FAA does allow arbitration agreements to be invalidated based on "generally applicable contract defenses," such as fraud, duress, or unconscionability. California courts have frequently utilized the doctrine of unconscionability to strike down employment arbitration agreements. Under California law, for a contract provision to be unenforceable, it must be both procedurally and substantively unconscionable. Procedural unconscionability typically involves "oppression" or "surprise" due to unequal bargaining power, while substantive unconscionability focuses on "overly harsh" or "one-sided" results.
The Phan decision is a quintessential example of how California courts apply these doctrines to navigate around the FAA’s pro-arbitration stance by focusing on the specific wording and scope of the agreement.
Case Analysis: Phan v. Knight Sacramento SU Inc.
The litigation began when an employee, Phan, filed a lawsuit against her employer, Knight Sacramento SU Inc. The employer moved to compel arbitration, citing a signed agreement that required all disputes to be resolved through an arbitrator rather than the court system. The trial court denied the motion, finding the agreement unconscionable. The employer subsequently appealed, leading to the current decision by the Court of Appeal.
Procedural Unconscionability: The "Take-It-or-Leave-It" Standard
The Court of Appeal first addressed procedural unconscionability. It upheld the trial court’s finding that the agreement was procedurally unconscionable because it was presented as a condition of employment. In California, such "contracts of adhesion"—where an employee has no meaningful opportunity to negotiate terms—are almost always found to have at least a moderate degree of procedural unconscionability. The court noted that when an employee is told they must sign the document to keep or obtain a job, the element of "oppression" is inherently present.
Substantive Unconscionability: The Problem of Overbreadth
The more significant blow to the employer came in the court’s analysis of substantive unconscionability. The court identified two specific provisions that it deemed unlawful:
- Scope of Claims: The agreement specified that arbitration was required for all claims "which arise out of the employment context or any other interaction/relationship" between the parties. The court, citing the 2024 precedent Cook v. University of Southern California, ruled that this language was impermissibly broad. By requiring arbitration for "any other interaction," the agreement theoretically forced the employee to arbitrate personal disputes that had nothing to do with her job—such as a hypothetical car accident with a manager outside of work hours. The court found no reasonable business justification for such an expansive requirement.
- Third-Party Beneficiaries: The agreement allowed the company’s owners, employees, and related corporate entities to enforce the arbitration clause. The court found this lacked "mutuality." While the employee was forced to arbitrate claims against these third parties, those third parties had not signed the agreement and were not reciprocal bound to arbitrate claims they might have against the employee.
The Doctrine of Severability
One of the most critical aspects of the Phan ruling is the court’s refusal to "sever" the offending clauses. Usually, when a contract contains a few illegal lines, a court can strike those lines and enforce the rest of the agreement. This is known as the severability doctrine.
However, the Court of Appeal in Phan exercised its discretion to invalidate the entire agreement. The court reasoned that the "central purpose" of the contract was tainted. By attempting to sweep in all possible interactions and all possible third-party affiliates, the employer had created an agreement so permeated by unconscionability that it could not be saved by simply removing a few words. This "all-or-nothing" approach by the court serves as a stern warning to employers: a single overreaching clause can jeopardize the entire arbitration program.
A Chronology of California’s Arbitration Battle
The Phan decision is part of a decades-long chronology of legal shifts in California:

- 2000: Armendariz v. Foundation Health Psychcare Services, Inc.: The California Supreme Court establishes the baseline requirements for mandatory employment arbitration, including neutral arbitrators, adequate discovery, and no limitation on statutory remedies.
- 2011: AT&T Mobility LLC v. Concepcion: The U.S. Supreme Court rules that the FAA preempts California’s rule against class-action waivers in arbitration agreements, a major win for employers.
- 2019: Assembly Bill 51 (AB 51): California legislature attempts to ban mandatory arbitration agreements as a condition of employment.
- 2023: Bonta v. Chamber of Commerce: After years of litigation, the Ninth Circuit finally strikes down AB 51, ruling that it is preempted by the FAA.
- 2024: Cook v. University of Southern California: The California Court of Appeal sets the stage for Phan by ruling that overbroad arbitration clauses covering "any relationship" are unconscionable.
- 2026: Phan v. Knight Sacramento SU Inc.: The court reinforces the Cook decision and applies a strict standard against the severability of overreaching clauses.
Supporting Data: The Rise of Arbitration and Its Costs
Data from the Economic Policy Institute (EPI) indicates that since the early 2000s, the share of workers subject to mandatory arbitration has more than doubled. In California, it is estimated that over 65% of non-union private-sector employees are covered by these agreements.
The push for arbitration is driven by cost and efficiency. On average, employment arbitration cases are resolved in approximately 360 days, compared to nearly two years for cases in the California Superior Court system. Furthermore, legal defense costs in arbitration are often 30% to 40% lower than in jury trials. However, rulings like Phan create a counter-economic effect; if an agreement is found unenforceable, the employer must pay for the failed arbitration motion, the subsequent appeal, and then still face the original lawsuit in court, effectively doubling their legal expenditures.
Analysis of Implications for Employers
The Phan decision suggests that California courts are moving toward a "precision-only" standard for arbitration agreements. Legal experts suggest the following implications:
1. The End of "Catch-All" Phrases
Employers can no longer use broad language like "all disputes of any nature" or "any interaction between the parties." Agreements must be strictly limited to the employment relationship—wages, hours, termination, and harassment. Including personal or non-employment interactions is now a high-risk strategy that invites a total loss of the agreement.
2. Reevaluating Third-Party Clauses
The common practice of including parent companies, subsidiaries, and individual managers as protected third-party beneficiaries is under fire. To remain enforceable, these clauses must be carefully drafted to ensure they do not create a one-sided obligation that the court views as a lack of mutuality.
3. The Risk of Non-Severability
The Phan court’s refusal to sever the bad parts of the contract is a "nuclear option" for judges. It means employers cannot rely on "savings clauses" to protect them from aggressive drafting. If the court perceives the agreement was written in "bad faith" to maximize employer advantage, the whole document will be discarded.
Reactions and Perspectives
While the court’s decision is framed as a protection of employee rights, it has drawn criticism from the business community and some legal scholars. Critics argue that the court is displaying a "perceived hostility" to arbitration that the FAA was designed to eliminate. By finding a provision unconscionable simply because it is broad, the court may be failing to treat arbitration agreements on the same footing as other commercial contracts, which often include broad "all-dispute" clauses.
Furthermore, the critique regarding third-party beneficiaries highlights a practical impossibility: a company cannot force a third party (like an independent contractor or a separate corporate entity) to sign an agreement between the employer and the employee. By requiring mutuality from parties who are not even signatories to the contract, the court may be setting a standard that is impossible to meet.
Conclusion and Future Outlook
The decision in Phan v. Knight Sacramento SU Inc. serves as a critical reminder that in California, the "Whack-A-Mole" game continues. As federal courts reinforce the validity of arbitration, state courts continue to refine the definitions of unconscionability to provide employees with an avenue to the courtroom.
For businesses operating in the Golden State, the mandate is clear: the era of the "template" arbitration agreement is over. Employers must conduct a meticulous review of their existing contracts, stripping away overbroad language and ensuring that every provision has a clear, documented business justification. Failure to do so may result in the total invalidation of their arbitration programs, leaving them vulnerable to the very jury trials and class actions they sought to avoid. As the legal pendulum continues to swing, precision in drafting remains the only viable shield for California employers.
