volving commerce’ ” under §2–which, in turn, depends on the application of §1’s exception for certain “contracts of employment.”
To be sure, New Prime resists this straightforward understanding. The company argues that an arbitrator should resolve any dispute over §1’s application because of the “delegation clause” in the parties’ contract and what is sometimes called the “severability principle.” A delegation clause gives an arbitrator authority to decide even the initial question whether the parties’ dispute is subject to arbitration. Rent-A-Center, West, Inc. v. Jackson, 561 U. S. 63, 68–69 (2010). And under the severability principle, we treat a challenge to the validity of an arbitration agreement (or a delegation clause) separately from a challenge to the validity of the entire contract in which it appears. Id., at 70–71. Unless a party specifically challenges the validity of the agreement to arbitrate, both sides may be required to take all their disputes–including disputes about the validity of their broader contract–to arbitration. Ibid. Applying these principles to this case, New Prime notes that Mr. Oliveira has not specifically challenged the parties’ delegation clause and submits that any controversy should therefore proceed only and immediately before an arbitrator.
But all this overlooks the necessarily antecedent statutory inquiry we’ve just discussed. A delegation clause is merely a specialized type of arbitration agreement, and the Act “operates on this additional arbitration agreement just as it does on any other.” Id., at 70. So a court may use §§3 and 4 to enforce a delegation clause only if the clause appears in a “written provision in… a contract evidencing a transaction involving commerce” consistent with §2. And only if the contract in which the clause appears doesn’t trigger §1’s “contracts of employment” exception. In exactly the same way, the Act’s severability principle applies only if the parties’ arbitration agreement
