Opinion of the Court
resolve the merits of the dispute even if the court thinks that a party’s claim on the merits is frivolous. AT&T Technologies, 475 U. S., at 649−650. So, too, with arbitrability.
Third, Archer and White says that, as a practical and policy matter, it would be a waste of the parties’ time and money to send the arbitrability question to an arbitrator if the argument for arbitration is wholly groundless. In cases like this, as Archer and White sees it, the arbitrator will inevitably conclude that the dispute is not arbitrable and then send the case back to the district court. So why waste the time and money? The short answer is that the Act contains no “wholly groundless” exception, and we may not engraft our own exceptions onto the statutory text. See Exxon Mobil Corp. v. Allapattah Services, Inc., 545 U. S. 546, 556–557 (2005).
In addition, contrary to Archer and White’s claim, it is doubtful that the “wholly groundless” exception would save time and money systemically even if it might do so in some individual cases. Archer and White assumes that it is easy to tell when an argument for arbitration of a particular dispute is wholly groundless. We are dubious. The exception would inevitably spark collateral litigation (with briefing, argument, and opinion writing) over whether a seemingly unmeritorious argument for arbitration is wholly groundless, as opposed to groundless. We see no reason to create such a time-consuming sideshow.
Archer and White further assumes that an arbitrator would inevitably reject arbitration in those cases where a judge would conclude that the argument for arbitration is wholly groundless. Not always. After all, an arbitrator might hold a different view of the arbitrability issue than a court does, even if the court finds the answer obvious. It is not unheard-of for one fair-minded adjudicator to think a decision is obvious in one direction but for another fair-minded adjudicator to decide the matter the other way.
