FIRST APPELLATE DISTRICT

DIVISION THREE

HAAMID KHAN, Plaintiff and Respondent, A172063 v. COINBASE, INC., (City & County of San Francisco Super. Ct. No. CGC-24-615202) Defendant and Appellant.

Coinbase, Inc. operates an online business for customers who buy, sell, transfer and store digital currencies. In 2022, Haamid Khan created a user account so that he could access Coinbase’s services. In June 2024, Khan filed the underlying action to enjoin Coinbase from engaging in deceptive business practices, in violation of California’s unfair competition law (Bus. & Prof. Code, § 17200 et seq.; UCL) and false advertising law (id., § 17500 et seq.; FAL). Coinbase responded with a petition to compel contractual arbitration, which the trial court denied pursuant to McGill v. Citibank, N.A. (2017) 2 Cal.5th 945, 955 (McGill). The court’s decision was supported by findings that Khan is seeking public injunctive relief, and that the agreement’s purported waiver of Khan’s right to seek such relief is unenforceable under California law. (See McGill, at p. 961.) We affirm.

1 BACKGROUND Khan’s Complaint Khan alleges that Coinbase charges customers a “hidden” fee to conduct transactions on Coinbase’s website, which Coinbase refers to as a “Spread Fee.” According to the complaint, this fee is hidden from users through a combination of tactics. For example, when a customer seeks to make a purchase, the spread fee is not displayed on any of the screens that the customer reviews when placing an order. Nor is the spread fee included in the amount of the “Coinbase fee” that is displayed to consumers. Instead, Khan alleges, a customer is first quoted market price to purchase shares of various digital currencies, and after the customer indicates how much of a particular currency he or she wants to purchase, the customer is shown an “Order Preview” screen summarizing the proposed transaction. On this screen, a slightly higher “Price” is listed, one that includes the undisclosed spread fee. On a typical buy or sell transaction, Coinbase’s spread fee is one percent; on transactions converting one digital currency to another, the spread fee is typically two percent. The only way for a customer in the course of these transactions to discover that Coinbase is charging this added fee is if the customer clicks a “tooltip” icon next to the word “Price.” Khan alleges that Coinbase designed its platform to take advantage of less sophisticated customers by charging a spread fee only to consumers who use Coinbase’s “default trading option,” and not imposing a spread fee on customers who select the platform’s “Advanced” trading option. Khan also alleges that consumers are deceived by Coinbase’s platform. He recounts complaints that consumers made after discovering their transactions included a hidden fee. And he avers that he personally used Coinbase’s

2 default trading platform and was unaware at the time that he was being charged a hidden spread fee. Khan incorporates his factual allegations into causes of action for violating the UCL and the FAL. As to each claim, Khan alleges that Coinbase deceptively leads reasonable consumers to believe that the price quoted for a cryptocurrency transaction is the market price and that the “Coinbase fee” quoted to the consumer includes all fees the consumer will pay to complete the transaction. In fact, Khan alleges, “the ‘price’ Coinbase has quoted to and charged—and continues to quote to and charge—consumers for cryptocurrency trades on its default trading platform includes a hidden Spread Fee[,] and the ‘Coinbase fee’ understates Coinbase’s true fees by excluding the Spread Fee.” As to both of his causes of action, Khan seeks an injunction prohibiting Coinbase from continuing to engage in these unlawful practices. The Arbitration Agreement Before conducting a transaction with Coinbase, a customer must consent to the terms of a detailed user agreement. The appellate record contains two versions of the user agreement, a November 2022 agreement that was in effect when Khan created his account, and a May 2024 version that Khan attached to his complaint. Both versions incorporate an arbitration agreement, and three sections of the arbitration agreement are relevant to this appeal. 1

1 In their respective appellate briefs, the parties cite different versions of the user agreement. If they disagree about which version governs, we need not resolve the issue since the relevant provisions are the same in both versions of the arbitration agreement.

3 Section 1.1 states that, with discrete exceptions, “any dispute, claim, [or] disagreements” relating to the use of Coinbase’s services “will be resolved by binding arbitration, rather than in court.” The term “ ‘dispute’ ” is construed broadly and includes disputes that arose before the existence of the user agreement and after its termination. 2 Section 1.3 is captioned as a “Waiver of Class and Other Non- Individualized Relief.” This section contains a purported waiver of all rights to have a dispute brought or resolved on a “class, collective, representative, or mass action basis.” It states that “only individual relief is available,” and it precludes any customer or user from consolidating his or her dispute with that of another customer or user. Section 1.3 contains additional language expressly prohibiting an arbitrator from awarding non-individualized relief: “Subject to this Arbitration Agreement, the arbitrator may award declaratory or injunctive relief only in favor of the individual party seeking relief and only to the extent necessary to provide relief warranted by the party’s individual claim.” And section 1.3 contains a severability clause, which provides that if the waiver is deemed “unenforceable as to a particular claim or request for relief (such as a request for public injunctive relief),” that claim or request for relief shall be severed and litigated in court. Section 1.6 addresses the powers of the arbitrator, which includes authority to resolve disputes pertaining to the construction and scope of the arbitration agreement, with specified exceptions. Pertinent here, all disputes relating to the purported waiver of class or other non-individualized relief contained in section 1.3 of the arbitration agreement “shall be decided by a court of competent jurisdiction and not by an arbitrator.”

2Boldface and some capitalization that appear in the arbitration agreement are omitted from provisions that we quote in this opinion.

4 Petition to Compel Arbitration Coinbase filed a petition to compel arbitration pursuant to the Federal Arbitration Act (9 U.S.C. § 1 et seq.; FAA). It argued that the arbitration agreement is presumptively valid under the FAA, and that Khan’s claims fall within its broad scope. Coinbase acknowledged that it could not compel Khan to arbitrate a claim for public injunctive relief, but it argued that Khan’s claims seek only private relief on behalf of himself and a group of similarly situated individuals. Khan opposed the petition on the ground that he is seeking an injunction that prohibits unfair business practices in order to protect the public, which falls within the definition of public injunctive relief. Relatedly, Khan argued the arbitration agreement is invalid to the extent it purports to strip consumers of their statutory right to seek public injunctive relief under California’s consumer protection laws. On November 21, 2024, the trial court denied Coinbase’s petition in a written order. As an initial matter, the court found the arbitration agreement does indeed contain an impermissible waiver of the right to obtain public injunctive relief, which is invalid under McGill, supra, 2 Cal.5th 945.
