ORDER

THOMAS S. ZILLY, District Judge.

THIS MATTER comes before the Court on a motion brought by plaintiff Port of Bellingham (the "Port") for partial summary judgment, docket no. 67. Having reviewed all papers filed in support of and in opposition to the Port's motion, the Court enters the following order.

Background

This consolidated action arises out of a fire that erupted on March 30, 2012, in Squalicum Harbor in Bellingham, Washington, claiming the lives of Jim A. Langei and Sterling Taylor, husband and wife. The fire destroyed the G East Boathouse1 of the Squalicum Marina and the twelve (12) non-commercial yachts moored there, including the M/Y BREAKWIND, which was owned by Langei and Taylor, all of which sank into the Harbor's navigable waters. The Port of Bellingham and its insurer Lexington Insurance Company ("Lexington") initiated this litigation against Langei's and Taylor's estates (the "Estates"), seeking to recover the amounts expended in salvaging the Boathouse and vessels, in remediating the associated oil and other pollution, and in storing and disposing of the related debris. See Am. Compls. (v. Langei Estate) (docket nos. 15 & 17); Compls. (v. Taylor Estate) (C12-1756, docket no. 1 & C12-1785, docket no. 1).

In response, the Estates asserted a right to exoneration or limitation of liability pursuant to 46 U.S.C. §§ 30501-30512 (the "Limitation Act"). They also pleaded, as an affirmative defense, that the Port's damages were caused by the "negligence of others," and invoked the doctrines of comparative and contributory negligence. Answers (docket nos. 39, 40, 43, & 44). A few months later, the Estates commenced proceedings in Whatcom County Superior Court against the Port, alleging that the Port is liable for Langei's and Taylor's deaths because (i) the fire resulted from the Port's faulty electrical components, and/or (ii) the Port's fire suppression system was inadequate. See Estates' Compl. at ¶¶ 3.1-3.7, Ex. F to Fix Decl. (docket no. 68). In the wrongful death action in Whatcom County Superior Court, the Port moved for a stay, but its motion was denied without prejudice. See Ex. G to Fix. Decl. The Port now seeks relief from this Court in two respects: (i) the Port requests a ruling that certain of its claims against the Estates are not subject to the Limitation Act; and (ii) the Port asks the Court to hold that the Estates' failure to plead the wrongful death claims as compulsory counterclaims in this action bars the Estates from pursuing such claims in state court.

Discussion

A. Exoneration or Limitation of Liability

Under federal law, the liability of a seagoing vessel owner for damage caused by the vessel may be limited, under certain conditions, to the post-accident value of the vessel plus any pending freight. See In re Glacier Bay, 944 F.2d 577, 579 (9th Cir. 1991); see also 46 U.S.C. §§ 30502 & 30505. In this action, the Port and Lexington assert several claims against the Estates, including violation of four (4) federal statutes, namely the Oil Pollution Act of 1990 ("OPA"), the Comprehensive Environmental Response, Compensation, and Liability Act of 1980 ("CERCLA"), the Federal Water Pollution Control Act ("Clean Water Act"), and the Wreck Removal Act ("WRA"),2 as well as violation of a state statute, namely Washington's Model Toxics Control Act ("MTCA"), RCW Chapter 70.105D.3 See Am. Compls. at 4th, 5th, 6th, 7th, & 8th Causes of Action (docket nos. 15 & 17); Compls. at 4th, 5th, 6th, & 7th Causes of Action (C12-1756, docket no. 1 & C12-1785, docket no. 1). The Port and Lexington also allege that the Estates have indemnification obligations pursuant to a personal contract executed by Langei, namely the Moorage Agreement dated March 2, 2010. See Am. Compls. at 1st & 12th Causes of Action; Compls. at 1st & 11th Causes of Action; see also Ex. A to Fix Decl. With respect to these claims, the Port seeks a ruling that the Estates may not limit their liability to the post-fire value of the M/Y BREAKWIND, which was destroyed and is now worthless.

In response, the Estates do not dispute that each federal statute at issue contains, with respect to any claims brought under such statute, an express or implied "repeal" of the Limitation Act.4 Likewise, the Estates do not quarrel with the proposition that the Limitation Act would not relieve them from any liability under the MTCA5 or pursuant to the Moorage Agreement.6 Rather, the Estates contend only that (i) they are not liable because the fire did not result from the acts of the decedents or because the decedents are entitled to the benefit of exculpatory provisions of the statutes at issue; (ii) the Port is not a proper plaintiff under the Clean Water Act or the WRA;7 and (iii) the Estates are not proper defendants under the MTCA.8 The Estates, however, have not themselves moved for any relief, and the Court DECLINES to further address these contentions at this time.

With respect to the issue of whether the federal and state statutory claims and the contract claims fall outside the scope of the Limitation Act, the Court GRANTS the Port's motion for partial summary judgment as follows. See Fed. R. Civ. P. 56(a). Any damages that might be awarded to the Port in connection with its claims under the OPA, CERCLA, the Clean Water Act, the WRA, the MTCA, or the Moorage Agreement will not be limited to the salvage value of the M/Y BREAKWIND, notwithstanding 46 U.S.C. §§ 30501-30512. The Court, however, makes no ruling concerning the cognizability of, or any liability of the Estates relating to, such claims.

B. Compulsory Counterclaim for Wrongful Death

In a federal action, a responsive pleading must include any mature compulsory counterclaim. Fed. R. Civ. P. 13(a). A counterclaim is compulsory if it arises out of the same transaction or occurrence as the opposing party's claim, is not the subject of another pending action, and does not require the joinder of a party over which the Court cannot acquire jurisdiction. Id. A counterclaim is mature when the conditions precedent to its assertion have been satisfied. See Stone v. Dep't of Aviation, 453 F.3d 1271, 1276-77 (10th Cir. 2006); Keller Transp., Inc. v. Wagner Enters., LLC, 873 F.Supp.2d 1342, 1354-55 (D. Mont. 2012). The Port asserts that the Estates were required to plead their wrongful death claims as counterclaims in this matter and that, because they failed to do so, they are now precluded from proceeding on the wrongful death claims in state court.

In response to the Port's motion, the Estates do not dispute that their wrongful death claims against the Port arise out of the same "occurrence" as the Port's claims against the Estates,9 and they do not suggest that the wrongful death claims would require the addition of another party over whom the Court cannot acquire jurisdiction. See Fed. R. Civ. P. 13(a)(1). The Estates contend solely that, because they had not yet presented their wrongful death claims to the Port as required by RCW 4.96.020, the claims were not mature at the time the Estates filed their answers and therefore were not compulsory counterclaims. Although the Estates' position finds support in Stone and Keller Transp., those cases are distinguishable, involving right-to-sue letters and the prerequisites for private claims under the OPA, respectively.

The issue in this case, whether the presentment requirements of RCW 4.96.020 are waived with respect to any compulsory counterclaims when a municipal corporation itself initiates suit, appears to be an issue of first impression. Courts have previously held, however, that sovereign immunity is waived as to compulsory counterclaims when a state or municipality invokes the jurisdiction of the federal courts. Competitive Techns. v. Fujitsu Ltd., 286 F.Supp.2d 1118, 1129 (N.D. Cal. 2003) (citing In re Lazar, 237 F.3d 967, 978 (9th Cir. 2001)); City of Newark v. United States, 254 F.2d 93 (3d Cir. 1958). Such waiver of sovereign immunity might extend to the notice-of-claim condition precedent to commencing an action against the sovereign, and if so, would undermine the Estates' assertion that their wrongful death claims were not mature at the time they filed their answers. The Court, however, DECLINES to rule on this issue because the Port would not be entitled to the relief it seeks even if the Estates' wrongful death claims constituted mature compulsory counterclaims.

The Port's position that the wrongful death claims are barred by the failure to plead them as counterclaims is premised on a misunderstanding concerning Rule 13. Although the failure to plead a compulsory counterclaim in a prior action might bar a subsequent suit, the legal theory leading to such result is the doctrine of res judicata, which operates only after the first case, in which the compulsory counterclaim was omitted, has reached final judgment. See Pochiro v. Prudential Ins. Co. of Am., 827 F.2d 1246, 1253-54 (9th Cir. 1987); see also Mitchell v. CB Richard Ellis Long Term Disability Plan, 611 F.3d 1192, 1201 (9th Cir. 2010) ("where a party has failed to plead a compulsory counterclaim, the claim is waived and the party is precluded by principles of res judicata from raising it again"). Rule 13 does not itself prevent the filing of a separate lawsuit instead of a compulsory counterclaim. See William W. Schwarzer, A. Wallace Tashima, & James M. Wagstaffe, FEDERAL CIVIL PROCEDURE BEFORE TRIAL at ¶ 8:1177 (2014).

Moreover, while the federal action in which the counterclaim should have been interposed remains pending, leave of the Court may be sought to amend the answer to include the omitted counterclaim.10 The Port fails to explain why, if the Estates were to move for leave to amend to assert wrongful death counterclaims,11 the Court would not grant such motion. Indeed, the discovery deadline of December 30, 2014, has not yet expired, the trial date of April 13, 2015, is over nine months away, and the Port has been aware of these potential counterclaims since November 2013, when the state action was commenced. In sum, the Port has not articulated any prejudice that might result from granting the Estates leave to amend their answers, see Fed. R. Civ. P. 15(a)(2), and it has not demonstrated that any failure to plead a compulsory counterclaim could not, at this time, still be cured.

In advocating for a ruling that the wrongful death claims are now barred, the Port is essentially seeking an injunction against the pending litigation in state court. The law is clear that the Court cannot grant such relief. See 28 U.S.C. § 2283; see also Seattle Totems Hockey Club, Inc. v. Nat'l Hockey League, 652 F.2d 852, 855 n.5 (9th Cir. 1981) ("a federal court is barred by § 2283 from enjoining a party from proceeding in state court on a claim that should have been pleaded as a compulsory counterclaim in a prior federal suit"); Carter v. Bedford, 420 F.Supp. 927, 929 (W.D. Ark. 1976) ("[I]f a party asserts a claim in a state court that is a compulsory counterclaim in an already pending federal action, the federal court cannot enjoin the prosecution of the state proceeding. . . . The result is that in the absence of voluntary restraint by one of the courts, both the federal and state actions will proceed toward judgment and the first to reach that point will serve as the basis for asserting a res judicata or collateral estoppel defense in the action that is still being adjudicated." (quoting 6 WRIGHT & MILLER § 1418)); Nolen v. Hammet Co., 56 F.R.D. 361 (D.S.C. 1972).

The authorities cited by the Port do not support a contrary view. As recognized by those authorities, a tension exists between (i) the generally exclusive jurisdiction vested in federal courts to determine a vessel owner's right to exoneration or limitation of liability, and (ii) a claimant's right to pursue remedies against a vessel owner in state court. See, e.g., Lewis v. Lewis & Clark Marine, Inc., 531 U.S. 438, 442 (2001); compare Limitation Act, 46 U.S.C. § 30511(a) ("The owner of a vessel may bring a civil action in a district court of the United States for limitation of liability under this chapter.") with 28 U.S.C. § 1333(1) ("The district courts shall have original jurisdiction, exclusive of the courts of the States, of . . . [a]ny civil case of admiralty or maritime jurisdiction, saving to suitors in all cases all other remedies to which they are otherwise entitled." (emphasis added)). To reconcile the Limitation Act with the saving-to-suitors clause of § 1333, courts have carved out two exceptions to exclusive federal jurisdiction: (1) when the limitation fund (i.e., the value of the vessel and any pending freight) exceeds the amount of all claims asserted against the vessel owner, and (2) when only a single claimant seeks recovery against the vessel owner.12 Lewis, 531 U.S. at 442, 451.

These two exceptions constitute situations in which a concursus, i.e., a proceeding in which two or more competing claims are litigated, is unnecessary; when the limitation fund is sufficient to pay all potential claims or when only a single claim is made, the claims are not in conflict and need not be prioritized or satisfied in a pro rata fashion. See S&E Shipping, 678 F.2d at 642-43. In such circumstances, a parallel state court action does not jeopardize the vessel owner's rights under the Limitation Act. On the other hand, when the matter involves multiple claims that in the aggregate might exhaust the limitation fund, a concursus is required, and a federal district court may enjoin other proceedings relating to the maritime incident at issue, including those in state court, without running afoul of the Anti-Injunction Act, 28 U.S.C. § 2283. See 46 U.S.C. § 30511(c); Fed. R. Civ. P. Supp. Admiralty Rule F(3); Beal v. Waltz, 309 F.2d 721, 724 (5th Cir. 1962).

In indirectly asking this Court to enjoin the action in Whatcom County Superior Court, the Port contends that the Estates' wrongful death claims belong within the concursus relating to their claim for exoneration or limitation of liability. The Port, however, fails to explain how a concursus is even relevant when the bulk of the Port's claims against the Estates are beyond the reach of the Limitation Act, and when the Port In re McCarthy Bros. Co./Clark Bridge, 83 F.3d 821, 828 (7th Cir. 1996) ("The shipowner's right to a federal admiralty forum is tentative: the claimant's preference for a different forum will prevail . . . where the situation is appropriate under established case law for federal court abstention. When the federal court abstains, it retains jurisdiction over the limitation of liability question pending resolution of the liability issues."); see Gorman v. Cerasia, 2 F.3d 519, 526 (3d Cir. 1993) ("as long as the priority stipulations filed in the district court ensure that the shipowner will not be exposed to competing claims to the limited fund representing more than the value of his or her vessel, the district court may authorize the parties to proceed with the state court action"). is, in essence, a lone claimant. Opposing claims like those at issue here, in which each side blames the other for the injury, are not the type of competing claims that give rise to a concursus, in which all claimants are adverse to the same entity, i.e., the vessel owner, and vie for a share of the insufficient resources.

The Port further argues that the Estates are not "suitors" within the meaning of § 1333 and are therefore not entitled to pursue remedies outside of this Court's admiralty jurisdiction, citing Offshore of the Palm Beaches, Inc. v. Lynch, 741 F.3d 1251 (11th Cir. 2014), and that the Estates should not be permitted to benefit from a state court judgment while at the same time being able to disavow such judgment if it is adverse, citing Beal, 309 F.2d at 723.13 The circumstances in Lynch, Beal, and the other authorities on which the Port relies, however, differ from the posture of this case. In each of those other matters, the vessel owner pursued Limitation Act proceedings in federal court while one or more claimants brought suit against the vessel owner in state court. In contrast, here, the vessel owner is not the defendant in state court, but is instead the plaintiff, seeking to hold a municipal corporation liable for causing, or failing to provide the resources necessary to combat, the fire at issue. In asserting their wrongful death claims, the Estates are not acting as a vessel owner trying to shield or defend itself from liability. Rather, in their capacity as wrongful-death action plaintiffs, the Estates fall well within the ambit of "suitors" as contemplated in § 1333, and are entitled to choose a state forum for their maritime claims.

Conclusion

For the foregoing reasons, the Port's motion for partial summary judgment, docket no. 67, is GRANTED in part and DENIED in part. The Court HOLDS that the Port's federal and state statutory claims, as well as its contract claims, are not subject to or limited by the Limitation Act, 46 U.S.C. §§ 30501-30512. The Court, however, makes no ruling concerning the cognizability of, or liability related to, such claims. The Port's request that the Court deem the Estates' wrongful death claims precluded by the failure to plead them as counterclaims in this action and/or that the Court enjoin the related action in Whatcom County Superior Court is DENIED.

Given the timing of the Port's motion for partial summary judgment and the Court's ruling thereon, the Court sua sponte EXTENDS the deadline for amending pleadings. If the Estates wish to amend their answers to assert the wrongful death claims as counterclaims, they are hereby GRANTED LEAVE to do so via electronic filing of such amended pleadings on or before August 21, 2014.14

IT IS SO ORDERED.

The Clerk is directed to send a copy of this Order to all counsel of record.
