The district court has certified a nationwide class of all persons who since the beginning of 1996 have bought machine tools that include a “DX-32 Control Unit” manufactured by Bridgeport Machines.
A nationwide class in what is fundamentally a breach-of-warranty action, coupled with a claim of fraud, poses serious problems about choice of law, the manageability of the suit, and thus the propriety of class certification. See
In re Rhone-Poulenc Rorer Inc.,
The district judge recognized that the request for class certification presented difficult problems, and that on key points Szabo’s position had been contested. Sza-bo asserts, for example, that all oral representations by all Bridgeport distributors everywhere have been either authorized or ratified by Bridgeport itself; Bridgeport contends that this is untrue. Resolution of this dispute is vital to any sensible decision about class certification. Szabo contends that the DX-32 unit is unsuited to any machine tool with which it may be mated; Bridgeport contends that its operation depends at least in part on the tool it is controlling. Again the propriety of a class comprising all buyers of all machine tools that include DX-32 control units depends on the outcome of this disagreement. There are other important disputes that we need not discuss, for the district court handled all of them in the same way: the judge assumed that whatever Szabo alleges must be true. Proceeding as if class certification under Rule 23 were governed *675 by the same principles as evaluating the sufficiency of the complaint under Rule 12(b)(6), the district judge stated:
since the class determination is made at the pleading stage of the action, the substantive allegations in the complaint are accepted as true for purposes of the class motion. In re Synthroid, Marketing Litig.,188 F.R.D. 287 , 290 (N.D.Ill.1999); Jefferson v. Security Pacific Financial Svcs., Inc.,161 F.R.D. 63 , 66 (N.D.Ill.1995).
Bridgeport relies on Szabo’s deposition, wherein he indicated that numerous oral representations were made to him by Bridgeport’s alleged agent (Advanced Machinery), as well as a demonstration of the product. Bridgeport then concludes that Szabo’s claim is one based on oral misrepresentations, which oral misrepresentations would be different for each potential Class member, and, therefore, class certification is not permissible. Clearly, Bridgeport is forgetting that this court must accept the substantive allegations of Szabo’s complaint as true. In re Synthroid Mktg. Litig.,188 F.R.D. 287 , 290 (N.D.Ill.1999).
Id. at 286. And this passage:
[The court follows] the principle that, in ruling on a class certification, the question is ‘whether plaintiff is asserting a claim which, assuming its merit, will satisfy the requirements of Rule 23....’ Eggleston v. Chicago Journeymen Plumbers’ Local No. 130,657 F.2d 890 , 895 (7th Cir.1981) (emphasis added).... Bridgeport is not permitted, at this stage, to contest the validity of [Szabo’s] theory that the local dealer with whom [Szabo] dealt was Bridgeport’s agent.
Id. at 293. In sum, the district judge certified the class without resolving factual and legal disputes that strongly influence the wisdom of class treatment. The judge stated that he had no other option.
For two reasons, we have granted Bridgeport’s request for discretionary appellate review under Rule 23(f). First, the class certification turns a $200,000 dispute (the amount that Szabo claims as damages) into a $200 million dispute. Such a claim puts a bet-your-company decision to Bridgeport’s managers and may induce a substantial settlement even if the customers’ position is weak. This is a prime occasion for the use of Rule 23(f), not only because of the pressure that class certification places on the defendant but also because the ensuing settlement prevents resolution of the underlying issues.

Blair v. Equifax Check Services, Inc.,
Which, we hold, they did not. The proposition that a district judge must accept all of the complaint’s allegations when deciding whether to certify a class cannot be found in Rule 23 and has nothing to recommend it. The reason why judges accept a complaint’s factual allegations when ruling on motions to dismiss under Rule 12(b)(6) is that a motion to dismiss tests the legal sufficiency of a pleading. Its factual sufficiency will be tested later — by a motion for summary judgment under Rule 56, and if necessary by trial. *676 By contrast, an order certifying a class usually is the district judge’s last word on the subject; there is no later test of the decision’s factual premises (and, if the case is settled, there could not be such an examination even if the district judge viewed the certification as provisional). Before deciding whether to allow a case to proceed as a class action, therefore, a judge should make whatever factual and legal inquiries are necessary under Rule 23. This would be plain enough if, for example, the plaintiff alleged that the class had 10,000 members, making it too numerous to allow joinder, see Rule 23(a)(1), while the defendant insisted that the class contained only 10 members. A judge would not and could not accept the plaintiffs assertion as conclusive; instead the judge would receive evidence (if only by affidavit) and resolve the disputes before deciding whether to certify the class. What is true of disputes under Rule 23(a)(1) is equally true of disputes under Rule 23(b)(3). A court may certify a class under Rule 23(b)(3) only if it finds that all of the prerequisites (such as numerosity) have been demonstrated, and in addition
the court finds that the questions of law or fact common to the members of the class predominate over any questions affecting only individual members, and that a class action is superior to other available methods for the fair and efficient adjudication of the controversy. The matters pertinent to the findings include: (A) the interest of members of the class in individually controlling the prosecution or defense of separate actions; (B) the extent and nature of any litigation concerning the controversy already commenced by or against members of the class; (C) the desirability or undesirability of concentrating the litigation of the claims in the particular forum; (D) the difficulties likely to be encountered in the management of a class action.
Questions such as these require the exercise of judgment and the application of sound discretion; they differ in kind from legal rulings under Rule 12(b)(6). And if some of the considerations under Rule 23(b)(3), such as “the difficulties likely to be encountered in the management of a class action”, overlap the merits — as they do in this case, where it is not possible to evaluate impending difficulties without making a choice of law, and not possible to make a sound choice of law without deciding whether Bridgeport authorized or ratified the dealers’ representations — then the judge must make a preliminary inquiry into the merits.
Courts make similar inquiries routinely under Rule 12(b)(1) and 12(b)(2) before deciding whether they possess jurisdiction over the subject matter of the case and the persons of the defendants, the location of the proper venue, application of
forum non conveniens,
and other preliminary issues. Often personal jurisdiction is closely linked to the nature, and merit, of the claim being asserted, see, e.g.,
Sheet Metal Workers’ National Pension Fund v. Elite Erectors, Inc.,
The district judge thought that
Eisen v. Carlisle & Jacquelin,
The district court’s approach, by contrast, is reminiscent of the “across-the-board” rule jettisoned by
General Telephone Co. v. Falcon,
Szabo’s proposed class is highly problematic, for reasons given in RhonePoulenc Rorer and sketched above. Nagging issues of choice of law, commonality, and manageability beset this case. It is unlikely that dealers in different parts of the country said the same things to hundreds of different buyers. (Szabo stresses that Bridgeport accepted each order at its home office, but this does not demonstrate that Bridgeport knew of or ratified any *678 particular representation by any given dealer.) It is unlikely that other models of milling machines exhibit the same problems that Szabo says that the DX-32 unit has caused in his model. And it is unnecessary to certify a nationwide class. Each buyer has a substantial claim, of the sort that could be, and often is, pursued independently. If any class treatment is appropriate, a class limited to a single state (or customers of a single dealer) would be more practical — though buyers in a single state (or of a single kind of machine) may be too few to justify class treatment. Now that the district court is free to pierce the allegations of the complaint, it may find these and other daunting obstacles good reasons to deny Szabo’s request for class certification or certify a more limited class. The order certifying the class accordingly is vacated, and the case is remanded for further proceedings consistent with this opinion.
