Respondents - passengers and representatives of the estates of passengers on a cruise ship hijacked by terrorists - filed suit in the District Court against petitioner, the ship's owner, to recover damages for personal injuries and for the wrongful death of one passenger. Before trial, petitioner moved to dismiss the actions, citing the forum-selection clause printed on each passenger ticket, which purported to obligate passengers to institute any suit in connection with the contract in Italy and to renounce the right to sue elsewhere. The District Court denied the motions, holding that the ticket did not give passengers reasonable notice that they were waiving the opportunity to sue in a domestic forum. The Court of Appeals dismissed petitioner's appeal on the ground that the District Court's dismissal orders were interlocutory and not appealable under 28 U.S.C. 1291, holding that the orders did not fall within the exception to the rule of nonappealability carved out by the collateral order doctrine.

Held:

An interlocutory order denying a defendant's motion to dismiss a damages action on the basis of a contractual forum-selection clause is not immediately appealable under 1291. Such an order is not final in the usual sense, for it does not end the litigation on the merits but, on the contrary, ensures that the litigation will continue. Nor does the order fall within the narrow exception to the normal application of the final judgment rule known as the collateral order doctrine, for the order is not effectively unreviewable on appeal from final judgment. The right to be sued only in a particular forum, as compared to the right to avoid suit altogether, although not perfectly secured by an appeal after final judgment, is sufficiently vindicable at that stage and is not essentially destroyed if vindication is postponed until trial is completed. Moreover, the costs associated with unnecessary litigation, should it eventually be decided that the District Court erred in trying the case, do not warrant allowing an immediate appeal of a pretrial order. That there may be a policy favoring enforcement of foreign forum-selection clauses goes to the merits of petitioner's claim that its ticket agreement requires that suit be filed in Italy and that the agreement should be enforced by the federal courts, but does not affect the appealability of a prejudgment [490 U.S. 495, 496] order, which turns on the contours of the right asserted, not on the likelihood of eventual success on the merits. Pp. 497-501.

JUSTICE BRENNAN delivered the opinion of the Court.

We granted certiorari to consider whether an interlocutory order of a United States District Court denying a defendant's motion to dismiss a damages action on the basis of a contractual forum-selection clause is immediately appealable under 28 U.S.C. 1291 as a collateral final order. We hold that it is not.

The District Court denied petitioner's motions to dismiss, holding that the ticket as a whole did not give reasonable notice to passengers that they were waiving the opportunity to sue in a domestic forum. Without moving for certification for immediate appeal pursuant to 28 U.S.C. 1292(b), Lauro Lines sought to appeal the District Court's orders. The Court of Appeals for the Second Circuit dismissed petitioner's appeal on the ground that the District Court's orders denying petitioner's motions to dismiss were interlocutory and not appealable under 1291. The court held that the orders did not fall within the exception to the rule of non-appealability carved out for collateral final orders in Cohen v. Beneficial Industrial Loan Corp., 337 U.S. 541 (1949). 844 F.2d 50 (1988). We granted certiorari to resolve a disagreement among the Courts of Appeals. 488 U.S. 887 (1988). Compare, e. g., 844 F.2d 50 (1988) (case below); Rohrer, Hibler & Replogle, Inc. v. Perkins, 728 F.2d 860, 862-863 (CA7) (holding prejudgment denial of motion to dismiss on basis of forum-selection clause not to be immediately appealable under 1291), cert. denied, 469 U.S. 890 (1984), with Hodes v. S. N.C. Achille Lauro ed Altri-Gestione, 858 F.2d 905, 908 (CA3 1988), cert. dism'd, 490 U.S. 1001 (1989); Sterling Forest Associates, Ltd. v. Barnett-Range Corp., 840 F.2d 249, 253 (CA4 1988); Farmland Industries, Inc. v. Frazier-Parrott Commodities, Inc., 806 F.2d 848, 851 (CA8 1986) (holding such denial to be an immediately appealable collateral final order). We now affirm.

We recently reiterated the "general rule" that an order is "effectively unreviewable" only "where the order at issue [490 U.S. 495, 499] involves `an asserted right the legal and practical value of which would be destroyed if it were not vindicated before trial.'" Midland Asphalt Corp., supra, at 798, quoting United States v. MacDonald, 435 U.S. 850, 860 (1978). If it is eventually decided that the District Court erred in allowing trial in this case to take place in New York, petitioner will have been put to unnecessary trouble and expense, and the value of its contractual right to an Italian forum will have been diminished. It is always true, however, that "there is value . . . in triumphing before trial, rather than after it," MacDonald, supra, at 860, n. 7, and this Court has declined to find the costs associated with unnecessary litigation to be enough to warrant allowing the immediate appeal of a pretrial order, see Richardson-Merrell Inc., supra, at 436 ("[T]he possibility that a ruling may be erroneous and may impose additional litigation expense is not sufficient to set aside the finality requirement imposed by Congress" in 1291). Instead, we have insisted that the right asserted be one that is essentially destroyed if its vindication must be postponed until trial is completed.

We have thus held in cases involving criminal prosecutions that the deprivation of a right not to be tried is effectively unreviewable after final judgment and is immediately appealable. Helstoski v. Meanor, 442 U.S. 500 (1979) (denial of motion to dismiss under the Speech or Debate Clause); Abney v. United States, 431 U.S. 651 (1977) (denial of motion to dismiss on double jeopardy grounds). See Midland Asphalt Corp., supra, at 801 ("A right not to be tried in the sense relevant to the Cohen exception rests upon an explicit statutory or constitutional guarantee that trial will not occur") (emphasis added). Similarly, in civil cases, we have held that the denial of a motion to dismiss based upon a claim of absolute immunity from suit is immediately appealable prior to final judgment, Nixon v. Fitzgerald, 457 U.S. 731, 742 -743 (1982), "for the essence of absolute immunity is its [490 U.S. 495, 500] possessor's entitlement not to have to answer for his conduct in a civil damages action," Mitchell v. Forsyth, 472 U.S. 511, 525 (1985). And claims of qualified immunity may be pursued by immediate appeal, because qualified immunity too "is an immunity from suit." Id., at 526 (emphasis in original).

On the other hand, we have declined to hold the collateral order doctrine applicable where a district court has denied a claim, not that the defendant has a right not to be sued at all, but that the suit against the defendant is not properly before the particular court because it lacks jurisdiction. In Van Cauwenberghe v. Biard, 486 U.S. 517 (1988), a civil defendant moved for dismissal on the ground that he had been immune from service of process because his presence in the United States had been compelled by extradition to face criminal charges. We noted that, after Mitchell, "[t]he critical question . . . is whether `the essence' of the claimed right is a right not to stand trial," 486 U.S., at 524 , and held that the immunity from service of process defendant asserted did not amount to an immunity from suit - even though service was essential to the trial court's jurisdiction over the defendant. See also Catlin v. United States, 324 U.S., at 236 (order denying motion to dismiss petition for condemnation of land not immediately appealable, "even when the motion is based upon jurisdictional grounds").

Lauro Lines argues here that its contractual forum-selection clause provided it with a right to trial before a tribunal in Italy, and with a concomitant right not to be sued anywhere else. This "right not to be haled for trial before tribunals outside the agreed forum," petitioner claims, cannot effectively be vindicated by appeal after trial in an improper forum. Brief for Petitioner 38-39. There is no obviously correct way to characterize the right embodied in petitioner's forum-selection provision: "all litigants who have a meritorious pretrial claim for dismissal can reasonably claim a right not to stand trial." Van Cauwenberghe, supra, [490 U.S. 495, 501] at 524. The right appears most like the right to be free from trial if it is characterized - as by petitioner - as a right not to be sued at all except in a Neapolitan forum. It appears less like a right not to be subjected to suit if characterized - as by the Court of Appeals - as "a right to have the binding adjudication of claims occur in a certain forum." 844 F.2d, at 55. Cf. Van Cauwenberghe, supra, at 526-527. Even assuming that the former characterization is proper, however, petitioner is obviously not entitled under the forum-selection clause of its contract to avoid suit altogether, and an entitlement to avoid suit is different in kind from an entitlement to be sued only in a particular forum. Petitioner's claim that it may be sued only in Naples, while not perfectly secured by appeal after final judgment, is adequately vindicable at that stage - surely as effectively vindicable as a claim that the trial court lacked personal jurisdiction over the defendant - and hence does not fall within the third prong of the collateral order doctrine.

Petitioner argues that there is a strong federal policy favoring the enforcement of foreign forum-selection clauses, citing The Bremen v. Zapata Off-Shore Co., 407 U.S. 1 (1972), and that "the essential concomitant of this strong federal policy . . . is the right of immediate appellate review of district court orders denying their enforcement." Brief for Petitioner 40-41. A policy favoring enforcement of forum-selection clauses, however, would go to the merits of petitioner's claim that its ticket agreement requires that any suit be filed in Italy and that the agreement should be enforced by the federal courts. Immediate appealability of a prejudgment order denying enforcement, insofar as it depends upon satisfaction of the third prong of the collateral order test, turns on the precise contours of the right asserted, and not upon the likelihood of eventual success on the merits. The Court of Appeals properly dismissed petitioner's appeal, and its judgment is

Affirmed. [490 U.S. 495, 502]

I join the opinion of the Court and write separately only to make express what seems to me implicit in its analysis.

The reason we say that the right not to be sued elsewhere than in Naples is "adequately vindicable," ante, at 501, by merely reversing any judgment obtained in violation of it is, quite simply, that the law does not deem the right important enough to be vindicated by, as it were, an injunction against its violation obtained through interlocutory appeal. The importance of the right asserted has always been a significant part of our collateral order doctrine. When first formulating that doctrine in Cohen v. Beneficial Industrial Loan Corp., 337 U.S. 541 (1949), we said that it permits interlocutory appeal of final determinations of claims that are not only "separable from, and collateral to, rights asserted in the action," but also, we immediately added, "too important to be denied review." Id., at 546 (emphasis added). Our later cases have retained that significant requirement. For example, in Abney v. United States, 431 U.S. 651 (1977), we said that in order to qualify for immediate appeal the order must involve "an important right which would be `lost, probably irreparably,' if review had to await final judgment." Id., at 658 (emphasis added), quoting Cohen, supra, at 546. And in Coopers & Lybrand v. Livesay, 437 U.S. 463 (1978), we said that the order must "resolve an important issue completely separate from the merits of the action." Id., at 468 (emphasis added). See also Van Cauwenberghe v. Biard, 486 U.S. 517, 522 -527 (1988); Gulfstream Aerospace Corp. v. Mayacamas Corp., 485 U.S. 271, 276 -277 (1988); Richardson-Merrell Inc. v. Koller, 472 U.S. 424, 431 (1985); Moses H. Cone Memorial Hospital v. Mercury Construction Corp., 460 U.S. 1, 12 (1983); Nixon v. Fitzgerald, 457 U.S. 731, 742 (1982).

While it is true, therefore, that the "right not to be sued elsewhere than in Naples" is not fully vindicated - indeed, to be utterly frank, is positively destroyed - by permitting [490 U.S. 495, 503] the trial to occur and reversing its outcome, that is vindication enough because the right is not sufficiently important to overcome the policies militating against interlocutory appeals. We have made that judgment when the right not to be tried in a particular court has been created through jurisdictional limitations established by Congress or by international treaty, see Van Cauwenberghe, supra. The same judgment applies - if anything, a fortiori - when the right has been created by private agreement. [490 U.S. 495, 504]
