Opinion of the Court
appears in a contract that falls within the field §§1 and 2 describe. We acknowledged as much some time ago, explaining that, before invoking the severability principle, a court should “determine[ ] that the contract in question is within the coverage of the Arbitration Act.” Prima Paint Corp. v. Flood & Conklin Mfg. Co., 388 U. S. 395, 402 (1967).

That takes us to the second question: Did the First Circuit correctly resolve the merits of the §1 challenge in this case? Recall that §1 excludes from the Act’s compass “contracts of employment of… workers engaged in interstate commerce.” Happily, everyone before us agrees that Mr. Oliveira qualifies as a “worker[ ] engaged in… interstate commerce.” For purposes of this appeal, too, Mr. Oliveira is willing to assume (but not grant) that his contracts with New Prime establish only an independent contractor relationship.
With that, the disputed question comes into clear view: What does the term “contracts of employment” mean? If it refers only to contracts that reflect an employer-employee relationship, then §1’s exception is irrelevant and a court is free to order arbitration, just as New Prime urges. But if the term also encompasses contracts that require an independent contractor to perform work, then the exception takes hold and a court lacks authority under the Act to order arbitration, exactly as Mr. Oliveira argues.

In taking up this question, we bear an important caution in mind. “[I]t’s a ‘fundamental canon of statutory construction’ that words generally should be ‘interpreted as taking their ordinary… meaning… at the time Congress enacted the statute.’ ” Wisconsin Central Ltd. v. United States, 585 U. S. ___, ___ (2018) (slip op., at 9)
