Opinion of the Court
statute does; and the district court was (once again) required to order arbitration.
Ultimately, the district court and the First Circuit sided with Mr. Oliveira. 857 F. 3d 7 (2017). The court of appeals held, first, that in disputes like this a court should resolve whether the parties’ contract falls within the Act’s ambit or §1’s exclusion before invoking the statute’s authority to order arbitration.

While a court’s authority under the Arbitration Act to compel arbitration may be considerable, it isn’t unconditional. If two parties agree to arbitrate future disputes between them and one side later seeks to evade the deal, §§3 and 4 of the Act often require a court to stay litigation and compel arbitration “accord[ing to] the terms” of the parties’ agreement. But this authority doesn’t extend to all private contracts, no matter how emphatically they may express a preference for arbitration.
Instead, antecedent statutory provisions limit the scope of the court’s powers under §§3 and 4. Section 2 provides that the Act applies only when the parties’ agreement to arbitrate is set forth as a “written provision in any maritime transaction or a contract evidencing a transaction involving commerce.” And §1 helps define §2’s terms. Most relevant for our purposes, §1 warns that “nothing” in the Act “shall apply” to “contracts of employment of seamen, railroad employees, or any other class of workers
