dissenting.
Before a court can compel arbitration under the Federal Arbitration Act,1 it must be “satisfied that the making of the agreement for arbitration ... is not in issue”.2 A challenge to the validity of a contract containing an arbitration provision does not put the making of the arbitration provision itself in issue; “as a matter of substantive federal arbitration law, an arbitration provision is severable from the remainder of the contract.”3 A challenge to the validity of the arbitration provision itself is for the court to decide; but “when parties agree’ to arbitrate all disputes arising under their contract, questions concerning the validity of the entire contract are to be resolved by the arbitrator in the first instance, not by a federal or state court.” 4 Thus for example, whether the contract was fraudulently induced,5 or whether it is usurious and therefore illegal,6 are issues for arbitration.
But what if the challenge to the contract is that it never came into being? Since “arbitration is a matter of contract”,7 the issue must be one for the court to decide. *193Otherwise, an arbitrator would be put in the position of deciding whether he was authorized to decide the parties’ dispute, concluding either that he was not authorized, a logical circularity, or that he was, and raising himself by his own bootstraps.8 Thus, whether a person is bound by a contract he never signed is an issue for the court.9 So, too, would seem to be issues whether a person’s signature on a contract was forged,10 whether a person’s agent was authorized to sign,11 and whether an offer was withdrawn before a contract was signed.12
The issue whether a party who executed a contract lacked the mental capacity to do so is different. The rule in Texas13 and most other jurisdictions14 is that the contract exists and can be ratified or avoided. That distinguishes the issue of capacity from issues of signature or authorization. A person who did not sign a contract or authorize its execution cannot enforce it; a person who lacks mental capacity to sign it can. Thus, it seems to me, lack of capacity is closer to fraudulent inducement than to lack of signature or authorization and therefore an issue for the arbitrator rather than the judge. The issue is not “the making of the agreement”; an agreement with a person lacking capacity exists — it happened. Rather, the issue is whether the agreement is valid and enforceable.
The Court reaches the opposite conclusion for two reasons, neither of which is compelling. First, the Court notes that the Supreme Court, in a footnote distinguishing “[t]he issue of the contract’s validity ... from the issue whether any agreement ... was ever concluded”, listed four cases that had been cited to it involving forgery, authorization, and mental capacity.15 But the Supreme Court expressed no opinion on any of these issues *194and did not note the important difference under some states’ laws that mental incapacity does not preclude an agreement. I think the Court overreads the footnote, though of course, one cannot be sure. As Professor Ware has observed:
Incapacity has long been a defense to the enforcement of a contract formed by a minor or mentally incompetent person. Such incapacity does not prevent the formation of a contract. So under the Supreme Court’s distinction between a contract’s formation (“whether any agreement ... was ever concluded”) and defenses to enforcement (“the contract’s validity”), incapacity plainly falls in the latter category and thus should be resolved by arbitrators rather than courts. Yet the Supreme Court in Buckeye grouped incapacity together with lack of assent and agency, both of which fall into the former category (formation) and both of which, First Options held, are resolved by courts rather than arbitrators. So it is possible that — when presented with an incapacity case — the Court will continue to group incapacity with lack of assent and agency and treat them all as questions for courts, rather than arbitrators.... Time will tell.16
Second, as between the two cases on the issue before us, the Tenth Circuit’s decision in Spahr v. Secco,17 and the Fifth Circuit’s decision in Primerica Life Ins. Co. v. Brown,18 the Court picks Spahr because the Fifth Circuit reached “a decidedly different result” in Will-Drill Resources, Inc. v. Samson Resources Co.19 and Primerica has been criticized for misapplying the separability doctrine. But Will-Drill repeatedly cites Primerica and discusses it approvingly,20 and the results in the two cases are entirely consistent. Primerica holds that the issue whether a contract, though made, is invalid is for the arbitrator; Will-Drill holds that the issue whether a contract was ever made is for the court. And even if Primerica was mistaken in concluding that capacity was an issue for arbitration simply because it was a challenge to a contract as a whole, that does not mean that the result was incorrect. Again, Professor Ware summarizes:
[C]ourts would hear questions about mutual assent, consideration, and authority to assent on behalf of others, while sending to arbitrators questions about misrepresentation (fraud in the inducement), mistake, duress, undue influence, incapacity, unconscionability, impracticability, frustration of purpose, the statute of frauds, the statute of limitations, illegality (or “public policy”), and expiration or termination. However, these latter issues are sent to the arbitrator only if they are challenges to the container contract as a whole; if they are “directed to the arbitration clause itself,” then they are heard by courts.21
Apart from the merits of the issue, there is another reason to hold that mental incapacity is for the arbitrator: the Fifth Circuit has done so. This Court has empha*195sized in the past that “it is important for federal and state law to be as consistent as possible in [applying the FAA], because federal and state courts have concurrent jurisdiction to enforce the FAA.”22 Federal courts in Texas must follow the Fifth Circuit, and state courts must follow this Court. After today, whether an issue of mental capacity is for the court or arbitrator in the first instance will depend on whether arbitration is sought in state or federal court. Today’s decision encourages the forum-shopping the Court has tried hard to avoid.
As Justice BristeR points out, the matter may end up being a small one. Helen Taylor’s guardian initially sued for breach of her contract with Morgan Stanley, then dropped that claim when he realized he could not stand on the contract and disavow the arbitration provision at the same time. The guardian now sues Morgan Stanley for breach of fiduciary duty arising out of the relationship between Taylor and Morgan Stanley, for recommending unsuitable transactions in violation of state securities laws, and for negligence. But the relationship between Taylor and Morgan Stanley was created and defined by their contract. If the guardian proves the contract was invalid, and Taylor and Morgan Stanley were simply strangers, it is not clear what duty Morgan Stanley owed or breached. The Court goes out of its way to work the guardian through the problems he has made for himself,23 but in repudiating any contract to avoid arbitration, he may well have cut off his arbitration nose to spite his litigation face.
