Coinbase, Inc. v. Bielski

This case originated when Abraham Bielski filed a class-action lawsuit against Coinbase, alleging the platform failed to replace funds lost from user accounts due to unauthorized transfers. Coinbase moved to compel arbitration based on its user agreement, but the district court denied the motion. Coinbase then filed an interlocutory appeal and requested an automatic stay of the district court proceedings. The district court and the Ninth Circuit refused to grant the stay. The U.S. Supreme Court granted certiorari to resolve a circuit split on whether an appeal of a denied motion to compel arbitration automatically divests the district court of jurisdiction to proceed with litigation.

In a 5-4 decision authored by Justice Kavanaugh, the Supreme Court reversed the Ninth Circuit, holding that a district court must stay its proceedings automatically while an interlocutory appeal on the question of arbitrability is pending. The majority reasoned this rule is mandated by the Federal Arbitration Act and the Griggs v. Provident Consumer Discount Co. principle, which treats an appeal from a denial of arbitration like an appeal from an injunction.

The central legal question was whether a district court must automatically stay its proceedings pending an interlocutory appeal from the denial of a motion to compel arbitration, or if the district court retains discretion to proceed with the case.

The ruling significantly strengthens the hand of companies seeking to enforce arbitration clauses by ensuring that litigation cannot proceed in tandem with an appeal on arbitrability. This reduces litigation costs and prevents district courts from undermining the arbitration process. However, critics, including the dissent, argued it provides a powerful tool for defendants to delay litigation and coerce settlements, even if the appeal is frivolous, impacting consumer and employment class actions substantially.
