The California Court of Appeal recently issued a decision in Phan v. Knight Sacramento SU Inc. (2026), further complicating the legal environment for employers seeking to enforce mandatory arbitration agreements within the state. This ruling serves as a poignant reminder of the "Whack-A-Mole" dynamic that characterizes California’s employment law landscape, where employers frequently find that as soon as one legal hurdle to arbitration is cleared through federal preemption, new state-level judicial defenses emerge to take its place. By affirming a trial court’s refusal to compel arbitration, the Phan decision highlights the rigorous scrutiny California courts apply to the doctrines of unconscionability and severability, effectively raising the bar for how these contracts must be drafted to survive appellate review.
The Judicial Challenge to Arbitration Enforcement
For over two decades, California has been at the center of a jurisdictional tug-of-war regarding the Federal Arbitration Act (FAA). While the United States Supreme Court has repeatedly signaled that the FAA preempts state laws and judicial rules that single out arbitration for disfavored treatment, California courts have remained vigilant in applying general contract defenses—most notably the doctrine of unconscionability—to invalidate agreements they deem unfair.
The metaphor of "Whack-A-Mole" is frequently invoked by legal practitioners in this field. It describes a scenario where employers adapt their agreements to comply with the latest Supreme Court or legislative mandate, only to have a new appellate decision narrow the path to enforcement. In Phan v. Knight Sacramento SU Inc., the court focused on the breadth of the arbitration scope and the perceived lack of mutuality regarding third-party beneficiaries, signaling a tightening of the requirements for "reasonable" contract terms in the employment context.
Case Background: Phan v. Knight Sacramento SU Inc.
The litigation began when an employee, Phan, filed suit against her employer, Knight Sacramento SU Inc. The employer moved to compel arbitration based on a signed agreement that was a condition of Phan’s employment. The trial court denied the motion, finding the agreement unconscionable and refusing to sever the offending portions to save the remainder of the contract.
Upon appeal, the California Court of Appeal scrutinized the agreement through the dual lens of procedural and substantive unconscionability. Under California law, both elements must be present to render a contract unenforceable, though they need not be present in the same degree. A "sliding scale" is used: the more substantively oppressive the contract term, the less evidence of procedural unconscionability is required to come to the conclusion that the term is unenforceable, and vice versa.
Procedural Unconscionability: The Adhesion Factor
The court first addressed the procedural aspect, which concerns the manner in which the contract was negotiated and the circumstances of the parties at the time. In Phan, the court found the agreement was procedurally unconscionable because it was a contract of adhesion—presented on a "take-it-or-leave-it" basis as a mandatory condition of employment. While this is a common feature of many employment contracts, California courts often view this lack of bargaining power as a foundational weakness that invites closer inspection of the contract’s substantive terms.
Substantive Unconscionability: Scope and Mutuality
The core of the Phan decision rested on two specific provisions deemed substantively unconscionable:
- Overly Broad Scope: The agreement required arbitration for any claims "which arise out of the employment context or any other interaction/relationship" between the parties. Relying on the precedent set in Cook v. University of Southern California (2024), the court determined this language was illegally broad. By extending the arbitration requirement to interactions outside the scope of employment, the court argued the employer was overreaching.
- Lack of Mutuality for Third Parties: The agreement allowed third-party beneficiaries—such as the company’s owners, other employees, and related corporate entities—to enforce the arbitration clause against the employee. However, it did not reciprocally obligate those third parties to arbitrate any claims they might bring against the employee. The court found this created a "one-sided" obligation that lacked the necessary mutuality to be fair under California law.
The Refusal to Sever: A Fatal Blow to Enforcement
One of the most critical aspects of the Phan ruling was the court’s refusal to apply the contract’s severability clause. Typically, if a court finds one or two provisions of a contract unlawful, it may "sever" or strike those specific lines and enforce the rest of the agreement.
However, the Court of Appeal upheld the trial court’s discretion to invalidate the entire agreement. The court reasoned that the "central purpose" of the contract was tainted by illegality. By attempting to capture all disputes (even non-employment ones) and providing lopsided protections for third parties, the court concluded that the agreement was "permeated" by unconscionability. This "all-or-nothing" approach by the judiciary poses a significant risk to employers, as a single poorly drafted sentence can now result in the total loss of the arbitration forum.
Historical Context: A Chronology of Conflict
To understand the weight of the Phan decision, one must look at the timeline of California’s relationship with arbitration:
- 2000: Armendariz v. Foundation Health Psychcare Services, Inc. – The California Supreme Court established five "minimum requirements" for mandatory employment arbitration, including neutral arbitrators, adequate discovery, and no requirement for employees to pay unreasonable costs.
- 2011: AT&T Mobility LLC v. Concepcion – The U.S. Supreme Court ruled that the FAA preempts state laws that prohibit class-action waivers in arbitration agreements, a major blow to California’s pro-consumer stance.
- 2022: Viking River Cruises, Inc. v. Moriana – The U.S. Supreme Court addressed the Private Attorneys General Act (PAGA), ruling that individual PAGA claims could be sent to arbitration, though the California Supreme Court later clarified in Adolph v. Uber Technologies (2023) that the representative portion of the claim could still proceed in court.
- 2024: Cook v. University of Southern California – This case set the stage for Phan by ruling against arbitration agreements that attempted to cover "any and all" disputes between a student/employee and the institution, regardless of their connection to the underlying agreement.
- 2026: Phan v. Knight Sacramento SU Inc. – The current ruling reinforces the Cook standard and adds new scrutiny to third-party beneficiary clauses.
Supporting Data and Industry Trends
The shift toward mandatory arbitration has been a defining trend in American labor relations. According to data from the Economic Policy Institute, more than 55% of private-sector non-union workers are currently subject to mandatory arbitration procedures. In California, despite the judicial pushback, that number is estimated to be even higher due to the high volume of employment litigation.
However, the "cost-saving" benefit of arbitration is being challenged. The rise of "mass arbitration"—where thousands of employees file individual claims simultaneously, forcing the employer to pay millions in upfront filing fees—has turned the tide. In response, some employers are actually moving away from mandatory arbitration, while others are doubling down on increasingly complex drafting strategies to avoid the pitfalls seen in the Phan case.
Legal Analysis: FAA Preemption vs. State Contract Defense
The Phan decision is not without its critics. Legal analysts argue that the court’s reasoning may run afoul of the FAA’s "equal footing" principle. The FAA requires that arbitration agreements be treated like any other contract. Critics of the Phan ruling suggest that a general contract requiring arbitration of "all disputes" between two parties would typically be enforceable in other contexts, and that by finding such a broad scope "unconscionable" specifically in the employment context, California courts are continuing to exhibit a "hostility to arbitration" that the U.S. Supreme Court has explicitly forbidden.
Furthermore, the critique of the third-party beneficiary clause ignores a practical reality: a third party cannot be forced into arbitration unless they have signed an agreement to do so. By demanding "mutuality" from parties who didn’t sign the primary contract, the court may be setting an impossible standard for employers who wish to protect their managers and affiliates from being sued individually in court as a "work-around" to the employee’s arbitration agreement.
Broader Implications for California Employers
The Phan decision necessitates an immediate review of existing arbitration templates. To mitigate the risk of total contract invalidation, employers should consider the following adjustments:
- Narrowing the Scope: Agreements should explicitly state that they apply only to claims "arising out of or related to the employment relationship." Attempting to cover "any interaction whatsoever" is now a proven liability.
- Revising Third-Party Clauses: If an agreement allows third parties (like supervisors or parent companies) to invoke arbitration, the language should be carefully balanced or supported by clear business justifications.
- Strengthening Severability: While the Phan court ignored severability, drafting clauses that specifically identify which provisions are essential and which are not may provide a stronger argument for "saving" the agreement in future disputes.
- Documenting Business Justification: If an employer insists on a broad scope, the agreement should include recitals explaining the legitimate business reasons for such breadth, potentially providing a defense against claims of substantive unconscionability.
Conclusion: Navigating the Future of Dispute Resolution
The ruling in Phan v. Knight Sacramento SU Inc. underscores the reality that in California, the enforceability of an arbitration agreement is never guaranteed. As the "Whack-A-Mole" game continues, the burden remains on employers to stay abreast of shifting judicial standards. The decision serves as a warning that the "all-encompassing" arbitration clause is a relic of the past; the future belongs to precisely tailored, mutual, and narrowly defined agreements that respect the specific boundaries of the employment relationship. Failure to adapt to this "new normal" of judicial scrutiny will likely result in more employers finding themselves stripped of their preferred dispute resolution forum and forced back into the very courtrooms they sought to avoid.
