OVERVIEW
Margaret Stewart, Dan Berryman, William Keith, Laura Spencer, Lee Callison, Stephanie Glowa, Terri Górecki, and Jam-ey Paulson (collectively “Plaintiffs”) appeal the district court’s dismissal of their complaint brought under the Employee Retirement Income Security Act of 1974 (“ERISA”), 29 U.S.C. §§ 1001-1461. The district сourt determined that Plaintiffs’ lawsuit was barred by res judicata because their claims could have been raised in a previous action. Plaintiffs ask us to reverse the district court’s ruling on the ground that res judicata does not apply because the dismissal of their previous action wаs not a decision on the merits. We have jurisdiction pursuant to 28 U.S.C. § 1291, and we affirm.
BACKGROUND
Plaintiffs worked as investment executives at U.S. Bancorp, but they were terminated in 1997 after U.S. Bancorp merged with First Bank System. U.S. Bancorp offered its departing employees generous severance packages. Two packages were available depending on the employee’s position: (1) the Broad Based Program that entitled low level, non-supervisory employees to eight weeks severance pay, and (2) the Middle Management Program that entitled supеrvisory employees to twelve months severance pay, plus a pro-rated bonus.
At the time of the merger Plaintiffs’ jobs were not formally classified as supervisory or non-supervisory. Plaintiffs believed their positions were analogous to middle management positions, but when the severance packages were disbursed, Plaintiffs received only the eight weeks severance pay for non-supervisors rather than the twelve months severance pay available to middle management employees. Plaintiffs responded by filing suit against U.S. Ban-corp in stаte court alleging breach of contract and wage claims under Oregon law. U.S. Bancorp removed the action to federal district court because Plaintiffs’ allegations of a “denial of benefits under an employee welfare benefit plan established and gоverned by ERISA,” presented federal questions under the doctrine of complete preemption.
Once in federal district court, U.S. Ban-corp filed a motion to dismiss pursuant to Federal Rule of Civil Procedure 12(b)(6) for failure to state a claim because: (1) ERISA preempted Plаintiffs’ state law claims, and (2) Plaintiffs had not pleaded the required elements for an ERISA claim. The magistrate judge agreed that ERISA federally preempted Plaintiffs’ state law claims and recommended dismissal. Plaintiffs did not object to the magistrate judge’s recommendation, nor did they seek lеave to amend their complaint to state a viable ERISA claim. Four months later, the district court adopted the magistrate judge’s findings and recommendation and dismissed Plaintiffs’ case. (“Stewart I ”) Plaintiffs did not appeal.
One. month after the dismissal of Stewart I, Plaintiffs filed a new complaint in *956 district court, this time alleging ERISA violations arising from the same denial of severance benefits. U.S. Bancorp filed a motion to dismiss based on res judicata. The district court noted that the two complaints arose out of the same “operational nucleus of facts” and that Plaintiffs “did not amend or seek leave to amend their [first] complaint to allege ERISA violations.” The district сourt applied res judi-cata and granted U.S. Bancorp’s motion to dismiss pursuant to Rule 12(b)(6). Plaintiffs appeal.
DISCUSSION
A. Standard of Review
We review de novo a district court’s dismissal based on res judicata.
Cabrera v. City of Huntington Park,
B. The District Court Correctly Found the Stewart I Dismissal To Be an Adjudication on the Merits.
1. Res Judicata and Federal Rule of Civil Procedure 41(b)
Res judicata, or claim рreclusion, prohibits lawsuits on “any claims that were raised
or could have been raised”
in a prior action.
Owens v. Kaiser Found. Health Plan, Inc.,
The phrase “final judgment on the merits” is often used interchangeably with “dismissal with prejudice.”
See, e.g., Paganis v. Blonstein,
2. Lack of Jurisdiсtion Exception To Federal Rule of Civil Procedure 41(b)
Congress enacted ERISA to “supersede any and all State laws insofar as they ... relate to any employee benefit plan.” 29 U.S.C. § 1144(a). The district court determined that because Plaintiffs’ state law claims related to a quаlifying benefit plan, they were federally preempted by ERISA. Consequently, it dismissed the case under Rule 12(b)(6) for failure to state a claim.
Plaintiffs contend that Rule 41(b)’s “lack of jurisdiction” exception applies to the
Stewart I
dismissal.
1
The
*957
Supreme Court has read Rule 41(b)’s “lack of jurisdiction” exception broadly, giving the concept of “jurisdiction” meaning beyond its traditional personal and subject matter usages: “[T]he exception ..encompasses] those dismissals which are based on a plaintiffs failure to comply with a precondition requisite to the Court’s going forward to detеrmine the merits of his substantive claim.”
Costello v. United States,
Rule 12(b)(6) dismissals are granted based on a plaintiffs failure to plead a cognizable claim. Using this yardstick, a district court analyzes the facts and legal claims in the complaint to determine if the plaintiff has alleged a cause of action. Supreme Court precedent confirms that a dismissal for failure to state a claim under Rule 12(b)(6) is a “judgment on the merits” to which res judicata applies.
Federated Dep’t Stores v. Moitie,
Plaintiffs concede that a Rule 12(b)(6) dismissal is generally on the merits, but argue that this Court must look past the label of the dismissal and examine the substance of the decision. For this proposition, they rely on
Criales v. American Airlines, Inc.,
*958 The Stewart I court analyzed the Plaintiffs’ complaint and dismissed it based on federal preemption of Plaintiffs’ state law claims. There was no unfulfilled preсondition in Stewart I that prevented the district court from considering the claims presented to it as there was in Costello and Criales. Plaintiffs’ state law claims were simply considered by the district court and rejected in light of federal preemption.
3. Recharacterization
Plaintiffs contend that the law required the district court in
Stewart I,
when presеnted with a preemption defense, to “re-characterize” the claims or at least to give Plaintiffs an opportunity to recharacterize the claims to comport with ERISA.
See Davis v. John Alden Ins. Co.,
The terms “eompléte preemption” and “recharacterization” are used when discussing federal question, removal jurisdiction.
See, e.g., Moran v. Rush Prudential HMO, Inc.,
On the other hand, federal preemption is a defense that applies once the court that is exercising jurisdiction considers the merits of the claims presented to it. Plaintiffs erroneously contend that the district court was required to “recharac-terize” their complaint to state an ERISA claim once it recharacterized the complaint for removal purposes. 2 Yet, our Circuit has distinguished between recharacterization for jurisdictional purposes and for federal preemption purposes: “The recharac-terization of a state claim as federal is independent from the process of finding that claim [federally] preempted.” Schroeder v. Trans World Airlines, Inc., 702 *959 F.2d 189, 192 (9th Cir.1983). The district court was not required to rewrite Plaintiffs complaint.
Once the district court recharacterized the Plaintiffs’ claims as federal, it became the Plaintiffs’ burden to amend their complaint to survive U.S. Bancorp’s motion to dismiss. Plaintiffs were on notice that their claims were preempted by ERISA, and they did not seek leave to amend or dismiss “withоut prejudice.” Leave would have been freely granted pursuant to Federal Rule of Civil Procedure 15. 3 Absent a request from Plaintiffs to amend, the district court had no other alternative but to dismiss the case, finding the only claims Plaintiffs presented were preempted.
CONCLUSION
Plaintiffs could havе stated an ERISA claim in their initial complaint, or the complaint could have been amended to include an ERISA claim. There was no initial bar to the district court’s considering an ERISA claim except Plaintiffs’ failure to raise it. In this respect, this case reminds us of the Supreme Court’s pointed observation in
Reed v. Allen,
The predicament in which respondent finds himself is of his own making.... [W]e cannot be expected, for his sole relief, to upset the general and well-established doctrine of res judicata, conceived in the light of the maxim that the interest of the state requires that there be an end to litigation — a maxim which comports with common sense as well as public policy. And the mischief which would follow the establishment of precedent for so disregarding this salutary doctrine against prolonging strife would be greater than the benefit which would result from relieving some case of individual hardship.
Moitie,
Dismissal was not for lack of jurisdiction, but rather for the substantive reason that Plaintiffs’ claims were preempted by federal law. Therefore, res judicata applies, and the Plaintiffs are barred from litigating any claims they raised or could have raised in Stewart I.
AFFIRMED.
Notes
. U.S. Bancorp argues that Plaintiffs are barred from making their "lack of jurisdic
*957
tion” argument on appeal because they did not raise it below. In general, a party who fails to raise an issue in the district court, cannot raise it on appeal.
Alaska Airlines, Inc. v. United Airlines, Inc.,
. Relying on Sorosky v. Burroughs Corp., 826 F.2d 794 (9th Cir.1987), Plaintiffs contend that if a complaint is completely preempted, the claims within it must be recharacterized by the district court to statе valid ERISA claims. Although Sorosky stated that "[o]ne consequence of complete preemption is that Sorosky has stated a valid ERISA claim,” the appeal dealt with state law claims that were not preempted. Id. at 801. To the extent that it addressed the preempted state law claims as recharacterized ERISA claims, its comments were dicta and unpersuasive.
. Federal Rule of Civil Procedure 15(a) instructs the courts that:
A party may amend the party’s pleading once as a matter of course at any time before a responsive pleading is served.... Otherwise a party may amend the party's pleading only by leave of court or by written consent of the adverse party; and leave shall be freely given when justice so requires.
