On Thursday, the U.S. Supreme Court delivered a unanimous decision against Coinbase Inc. (COIN), addressing an arbitration dispute that emerged from the cryptocurrency exchanges 2021 Dogecoin (DOGE) sweepstakes.

The 9-0 ruling clarified that a court must determine which legal agreement holds precedence when parties are governed by multiple contracts.

Supreme Court Upholds Lower Courts Authority

The question whether these parties agreed to arbitrate arbitrability can be answered only by determining which contract applies, Justice Jackson wrote. When we home in on the conflict between the delegation clause in the first contract and forum selection clause in the second, the question is whether the parties agreed to send the given dispute to arbitration – and, per usual, that question must be answered by a court.

Coinbase had previously sought to settle the dispute through arbitration, relying on user agreements mandating arbitration for all customers. However, a federal judge ruled in November that the sweepstakes terms, which specified Californias court system as the forum for related disputes, took precedence over the customer agreement.

The latest Supreme Court ruling confirmed that a lower court should determine which agreement controls this case. Justice Jackson also dismissed Coinbases argument that ruling against them would lead to widespread legal confusion and enable parties to evade arbitration agreements. We do not believe that such chaos will follow, they wrote.

Richard Silberberg, an arbitration lawyer with Dorsey Whitney, noted that the decision was hardly surprising given previous rulings and affirmed that a court, not an arbitrator, must decide whether the parties’ first agreement was superseded by the second.

They also noted that because of the cases narrow scope, it will have limited applicability in future arbitration-related cases.

Last year, Coinbase won in a different arbitration-related matter, supported by the court’s conservative majority. In response to the latest decision, Coinbases Chief Legal Officer Paul Grewal commented on X, Some you win. Some you lose. We are grateful for having had the opportunity to present our case to the court and appreciate the courts consideration of this matter.

The underlying lawsuit, initiated by former Coinbase user David Suski, alleges that the exchanges Trade Doge, Win Doge contest misled participants into believing that a $100 purchase or sale of Dogecoin was required for eligibility to win cash prizes.

However, the contest’s fine print revealed an alternative entry method via mail, avoiding the need for purchase in compliance with U.S. sweepstakes laws. Suski and other plaintiffs argue they would not have spent $100 on DOGE had they been aware of this loophole.
