The St. Johns River Terminal Company leased a tract of land (the “Leased Site”) in Jacksonville, Florida, to the Gulf Oil Corporation from 1906 to 1961. Gulf constructed above-ground tanks on the land to store oil and fuel. In 1977, the United States Coast Guard informed St. Johns that oil was leaking from the Leased Site onto the surface of the nearby Long Branch Creek and required St. Johns to remediate the leakage at its own expense. St. Johns sued Gulf for reimbursement for the cost of the cleanup.
Prior to trial, the parties settled. Gulf agreed to pay St. Johns $163,000 to help cover the cost of the containment efforts, and St. Johns executed a release, stating:
St. Johns River Termianl [sic] Company does hereby release and forever discharge said Gulf Oil Company, its successors and assigns, from any and all actions, causes of action, claims and demands for, upon or by reason of any damage, loss or injury, which heretofore has been or which hereafter may be sustained by St. Johns River Terminal Company arising out of any contamination by oil of the Talleyrand Terminal property in Jacksonville, Florida, which is alleged to have occurred during Gulf Oil Corporation’s use and occupancy of said property and all those matters alleged in [St. Johns’s 1977 lawsuit].
This release extends and applies to, and also covers and includes, all unknown, unforeseen, unanticipated and unsuspected injuries, damages, loss and liability, and the consequences thereof, arising out of said alleged oil contamination, as well as those now disclosed and known to exist.
We shall refer to this as the “Settlement Agreement.” Once the parties entered into this Agreement, the district court entered a judgment of dismissal with prejudice (the “1977 Dismissal”) based upon the parties’, joint stipulation, stating, “It is hereby agreed by and between all parties that the above entitled cause has been compromised and settled and that this cause is dismissed with prejudice under Rule 41 of the Federal Rules of Civil Procedure .... ”
The plaintiffs, Norfolk Southern Corporation and Georgia Southern and Florida Railway Company (collectively, “Norfolk”), are the successors-in-interest to St. Johns. The defendant, Chevron, is the successor-in-interest to Gulf. In 1999, Norfolk discovered that contamination from oil storage tanks on the Leased Site had leaked onto an adjacent salt marsh (“the Marsh”). *1288 The contaminants are known as “tank bottoms” because they formed from the sludge that accumulated at the bottom of the storage tanks.
Norfolk sued Chevron under both the Comprehensive Environmental Response, Compensation and Liability Act (CERC-LA), 42 U.S.C. §§ 9601-9675, and Florida common law, seeking reimbursement of expenses that it has incurred and will incur in cleaning up the leakage. The district court granted Chevron summary judgment, concluding that Norfolk’s claims were barred by the res judicata effect of the 1977 Dismissal. It held that a dismissal entered pursuant to a settlement agreement is presumed to have the same res judicata effect as any other judgment, although the scope of this preclusive effect may be limited by the agreement into which the parties entered.
The district court explained that a claim that would typically be barred under res judicata may be preserved only if a party makes a “clear expression” of a “reservation of right” to bring suit on the basis of that claim in the future. Because the Settlement Agreement did not expressly allow St. Johns (Norfolk’s predecessor-in-interest) to bring any future claims regarding contamination of the Leased Site, the court held that the Agreement did not curtail the scope of traditional res judicata principles. Applying those principles, the court held that Norfolk’s current claim was precluded and dismissed the case. Norfolk appeals, arguing that it should be entitled to proceed with its lawsuit.
Because
res judicata
determinations are pure questions of law, we review them
de novo. Israel Discount Bank Ltd. v. Entin,
A judgment dismissing an action with prejudice based upon the parties’ stipulation, unlike a judgment imposed at the end of an adversarial proceeding, receives its legitimating force from the fact that the parties consented to it. In the closely related context of consent decrees, we have recognized the importance of confining their scope to matters upon which the parties have consented.
United States v. Miami,
In determining the
res judicata
effect of an order of dismissal based upon a settlement agreement, we should also attempt to effectuate the parties’ intent. The best evidence of that intent is, of course, the settlement agreement itself. Consequently, the scope of the preclusive effect of the 1977 Dismissal should not be determined by the claims specified in the original complaint, but instead by the terms of the Settlement Agreement, as interpreted according to traditional principles of contract law.
See W.J. Perryman & Co. v. Penn. Mut. Fire Ins. Co.,
It might be argued that this way of applying
res judicata
to dismissals predicated upon settlement agreements does not adequately respect the fact that such a dismissal is an actual judgment. We believe it does, however, for two reasons. First,
res judicata
is an affirmative defense which must be pled, and may be waived, by the defendant.
Louisville & N.R. Co. v. M/V Bayou Lacombe,
Another important consideration is that, even under the caselaw the defendant cites, parties may avoid part of the
res judicata
effect of a consent-based dismissal simply by making an “express reservation” of the right to sue on a particular claim in the future.
See, e.g., Epic Metals Corp. v. H.H. Robertson Co.,
Under the approach we adopt today, the district court erred in beginning its analysis by first assuming that res judicata applied in full to all of the claims in the original 1977 complaint and then “carving out” from the scope of this preclusive effect only those claims that St. Johns expressly reserved in the Settlement Agreement. Instead, the court should have looked to the Settlement Agreement to determine what claims it precluded from future litigation.
Norfolk contends that we must look beyond the terms of the Settlement Agreement itself to determine the full range of claims that the parties intended to preclude in the future. As Norfolk points out, however, a settlement agreement is essentially a contract and is subject to the traditional rules of contract interpretation.
Monahan v. Comm’r,
Here, the Settlement Agreement clearly specifies the range of claims subject to preclusion. St. Johns released Gulf from any liability for “damage, loss or injury, which heretofore has been or which hereafter may be sustained by St. Johns River Terminal Company arising out of any contamination by oil of the [Leased Site].” By implication, this Agreement does not cover: (1) any damage arising due to contamination by anything other than oil (such as tank bottoms), or (2) any damage arising due to contamination of an area other than the Leased Site by oil, if such contamination occurred directly (that is, if it was not dependent upon contamination of the Leased Site). The scope of the release contained within the Agreement does not touch upon these subjects. Consequently, an “express reservation” of a right to sue was unnecessary to allow Norfolk to bring its current claims. Because Norfolk’s claims are predicated upon leakage of nonoil contaminants (tank bottoms), they are outside the scope of the Settlement Agreement, which addressed only oil contamination, and Norfolk’s current suit may proceed.
We recognize that
res judicata
typically precludes not only the specific claims brought in a complaint, but any other claims that stem “out of the same nucleus of operative fact, or is based upon the same factual predicate.”
Ragsdale v. Rubbermaid, Inc.,
In conclusion, where the parties stipulate to having a case dismissed, a somewhat modified form of res judicata applies to the written settlement agreement upon which such dismissal is predicated, if one exists. In the instant case, the Settlement Agreement did not preclude future suits based on nonoil contaminants, or based on contamination of other areas that did not stem from contamination of the Leased Site. Consequently, Norfolk’s suit against Chevron may proceed. In light of this holding, we need not reach any of the other issues raised by the parties.
The judgment of the district court is REVERSED.
