of their motion to compel arbitration of claims brought by Plaintiff-Appellees Jean
Pappas, Johannah Hetherington, Nicole Domke, Michelle Anderson, and Jane
Angell. We have jurisdiction under 9 U.S.C. § 16(a)(1) and reverse.
We review the denial of the motion to compel arbitration and the interpretation
of contracts de novo. Poublon v. C.H. Robinson Co., 846 F.3d 1251, 1259 (9th Cir.
2017). We review findings of fact for clear error. Lim v. TForce Logistics, LLC, 8
F.4th 992, 999 (9th Cir. 2021).
Under the Federal Arbitration Act, agreements to arbitrate are “valid,
irrevocable, and enforceable, save upon such grounds as exist at law or in equity for
the revocation of any contract.” AT&T Mobility LLC v. Concepcion, 563 U.S. 333,
339 (2011) (quoting 9 U.S.C. § 2). Courts must “place arbitration agreements on an
equal footing with other contracts and enforce them according to their terms” unless
those agreements fall afoul of “generally applicable contract defenses, such as fraud,
duress, or unconscionability.” Concepcion, 563 U.S. at 339 (simplified).
Under California law, a contract provision may be unenforceable if
“unconscionable at the time it was made.” Cal. Civ. Code § 1670.5(a). “A contract
is unconscionable if one of the parties lacked a meaningful choice in deciding
whether to agree and the contract contains terms that are unreasonably favorable to
the other party.” OTO, L.L.C. v. Kho, 447 P.3d 680, 689 (Cal. 2019). “Both
procedural and substantive unconscionability must be shown for the defense to be
2 25-473
established.” Id. at 690. “The procedural element addresses the circumstances of
contract negotiation and formation, focusing on oppression or surprise due to
unequal bargaining power.” Id. (simplified). “Substantive unconscionability
pertains to the fairness of an agreement’s actual terms and to assessments of whether
they are overly harsh or one-sided.” Id. (simplified).
The district court concluded that the employment contracts between AMN and
Plaintiffs-Appellees were unconscionable based solely on the cost-allocation
provision signed by the parties. It states, “[t]o the maximum extent permitted by
law, the arbitrator shall award the prevailing party its costs and reasonable attorney’s
fees; provided, however, that the arbitrator at all times shall apply the law for the
shifting of costs and fees that a court would apply to the claim(s) asserted.” Plaintiff-
Appellees argue that the cost-allocation provision is unconscionable because its
language may suggest to an employee that they may be assigned the prevailing
party’s costs, a cost-shift prohibited by California law. See Armendariz v. Found.
Health Psychcare Servs., Inc., 6 P.3d 669, 687 (Cal. 2000) (arbitration agreements
“cannot generally require the employee to bear any type of expense that the
employee would not be required to bear . . . in court”).
Plaintiffs-Appellees have not established substantive unconscionability. To
determine substantive unconscionability, courts look to “the fairness of an
agreement’s actual terms”—not the parties’ subjective understandings—to
3 25-473
determine whether the terms are “overly harsh or one-sided.” Kho, 447 P.3d at 690
(simplified) (emphasis added). Read in full, however, the contract provision here
prevents an arbitrator from shifting costs in a manner contrary to the law applicable
in California courts. So the provision does not permit violation of California cost-
allocation rules.
Plaintiffs-Appellees argue that this court’s decision in Ronderos v. USF
Reddaway, Inc. suggests that substantive unconscionability may arise from the
subjective misunderstandings of the parties. 114 F.4th 1080 (9th Cir. 2024). But
there, we held only that a layperson’s inability to understand the legal effect of the
cost-allocation provision at issue contributed to procedural unconscionability and
declined to address whether the provision was also substantively unconscionable.
Id. at 1093. Here, Plaintiffs-Appellees have not identified a risk that the provision
could, in effect, accomplish an impermissible cost award. And without showing
substantive unfairness, they cannot establish unconscionability.
We REVERSE and REMAND to the district court for entry of an order
granting the motion to compel arbitration.1

Plaintiffs-Appellees’ motion for judicial notice (Dkt. No. 33) is DENIED AS
MOOT as it pertains to the issue of severance, which we need not—and do not—
reach.
