25 I.INTRODUCTION
26 The State of California sued Exxon Mobil Corporation in California state court, averring
27 that the company bears responsibility for the global plastic waste and pollution crisis due to its
1 nonprofit organizations including Sierra Club, Inc., Surfrider Foundation, Inc., Heal the Bay,
2 Inc., and Baykeeper, Inc.(collectively, “Nonprofit Plaintiffs”) filed a substantially similar suit in
3 the same state court. Defendant removed each case to this court, asserting that maritime
4 jurisdiction, the federal enclave doctrine and/or federal officer jurisdiction apply to the claims.1
5 In removing Nonprofit Plaintiffs’ suit, Exxon also cited complete diversity, pursuant to 28
6 U.S.C. § 1332(a), and minimal diversity pursuant to the Class Action Fairness Act, 28 U.S.C.
7 § 1332(d). Nonprofit Plaintiffs do not contest that, with respect to their claims, complete
8 diversity is satisfied and the amount in controversy is met. The cases are now related, pursuant
9 to the parties’ stipulation, and both California and the Nonprofit Plaintiffs move for remand to
10 state court. For the reasons explained below, California’s remand motion is granted, and
11 Nonprofit Plaintiffs’ remand motion is denied.
12 II.BACKGROUND
13 A. California’s Complaint
14 California’s 147-page complaint (“Complaint”) advances a disturbing tale of alleged
15 corporate greed. According to its allegations, Exxon—the world’s largest producer of single-use
16 plastics—“deceived Californians for almost half a century by promising that recycling could and
17 would solve the ever-growing plastic waste crisis.” Complaint ¶ 2.2 All the while, the complaint
18 avers, “ExxonMobil has known that mechanical recycling, and now ‘advanced recycling,’ will
19 never be able to process more than a tiny fraction of the plastic waste it produces.” Id. In
20 particular, the state alleges the company “knew that the consequent amount of plastic waste
21 would continue to rise, inevitably leading to ever-increasing plastic pollution of the
22

23
1 Exxon’s theory of removal marks the latest instance of a fossil fuel company invoking creative
bases for federal jurisdiction over pollution-related state law claims. See, e.g., County of San
24
Mateo v. Chevron Corp. (“San Mateo II”), 32 F.4th 733 (9th Cir. 2022) (affirming remand for lack
of federal enclave, federal officer, bankruptcy, admiralty, federal question, or Outer Continental
25
Shelf Lands Act (“OCSLA”) jurisdiction); City & Cnty. of Honolulu v. Sunoco LP, 39 F.4th 1101,
1106 (9th Cir. 2022) (affirming remand for lack of federal enclave, federal officer, or OCSLA
26
jurisdiction); Bd. of Cnty. Comm’rs of Boulder Cnty. v. Suncor Energy (U.S.A.) Inc., 25 F.4th 1238
(10th Cir. 2022) (same); See also Rhode Island v. Shell Oil Prods. Co., 35 F.4th 44 (1st Cir. 2022);
27
see also Mayor of Baltimore v. BP P.L.C., 31 F.4th 178 (4th Cir. 2022).
1 environment” because it “knew that once plastic enters the environment, it is extremely costly
2 and difficult to eradicate” given the way it disintegrates into microplastics—that is, “tiny plastic
3 bits measuring five millimeters or less.” Id. ¶ 3. California claims that, due to Exxon’s actions,
4 “single-use plastic chokes our waterways, poisons our oceans, harms already endangered and
5 threatened wildlife, blights our landscapes, contaminates the recycling stream, increases waste
6 management costs, pollutes our drinking water, and expands landfills.” Id.¶ 6.
7 Based on the above allegations, California asserts six state law claims. As relief,
8 California seeks the following: an order compelling Defendant to abate the public nuisance it
9 allegedly created; preliminary and permanent injunctive relief ordering Defendant to cease and
10 desist allegedly deceptive public statements about its plastic operations, including topics such as
11 “advanced recycling” and “chemical recycling”; temporary and permanent equitable relief as
12 needed to protect and/or prevent further pollution; various monetary penalties authorized by state
13 statutes; and fees and costs. Id. ¶¶ 463–79.
14 B. Nonprofit Plaintiffs’ Complaint
15 Nonprofit Plaintiffs raise similar allegations in their complaint. Declaring that single-use
16 plastics “are harmful, toxic products that cannot be safely disposed through recycling or by other
17 means,” they aver that Exxon “created a single-use plastics pollution crisis in California by
18 concealing these facts for decades to sell more plastics.” Nonprofit Plaintiffs’ Complaint ¶ 1.3
19 Because their organizations have missions to prevent the harms caused by plastic pollution,
20 Nonprofit Plaintiffs say they have had to divert significant resources to combat the impact of
21 Exxon’s activities. Id. ¶ 19.
22 Nonprofit Plaintiffs’ complaint raises two state law claims that mirror two of those
23 alleged in the State’s suit. They seek injunctive relief (including abatement), compensatory
24 damages plus interest, and fees and costs. Id. ¶¶ 239–241.
25 C. Exxon’s Grounds for Removal
26
27
1 Exxon removed both California’s complaint and Nonprofit Plaintiffs’ complaint to the
2 Northern District of California. It first removed Nonprofit Plaintiffs’ complaint, citing diversity
3 jurisdiction under 28 U.S.C. § 1332(a). It also argued for jurisdiction under the Class Action
4 Fairness Act, contending that the complaint is a “de facto class action” since the claims are “on
5 behalf of [Plaintiffs] and the California public.” See Nonprofit Plaintiffs’ Complaint ¶ 22.
6 Exxon then removed California’s complaint, asserting the presence of maritime jurisdiction
7 under 28 U.S.C. § 1333, federal question jurisdiction (via the federal enclave doctrine) under 28
8 U.S.C. § 1331, and federal officer jurisdiction under 28 U.S.C. § 1442(a)(1).4
9 III.LEGAL STANDARD
10 A. Removal and Remand
11 A defendant has the right to remove to federal court “any civil action brought in a State
12 court of which the district courts of the United States have original jurisdiction.” 28 U.S.C.
13 § 1441(a). Original jurisdiction exists when a state case presents a federal question, involves
14 parties with complete diversity of citizenship plus at least $75,000 as the amount in controversy,
15 or falls under maritime law. See 28 U.S.C. §§ 1331, 1332, 1333. Removal is also authorized as
16 to actions against “any officer (or any person acting under that officer) of the United States or of
17 any agency thereof . . . for or relating to any act under color of such office.” 28 U.S.C.
18 § 1442(a)(1).
19 In construing these statutes, “[i]t is to be presumed that a cause lies outside the limited
20 jurisdiction of the federal courts.” Abrego Abrego v. Dow Chem. Co., 443 F.3d 676, 684 (9th
21 Cir. 2006) (cleaned up). “The strong presumption against removal jurisdiction means that the
22 defendant always has the burden of establishing that removal is proper, and that the court
23 resolves all ambiguity in favor of remand to state court.” Hunter v. Philip Morris USA, 582 F.3d
24 1039, 1042 (9th Cir. 2009) (internal quotation marks omitted).
25 B. Maritime Law
26 The Constitution grants federal courts original jurisdiction over “all Cases of admiralty and
27
1 maritime Jurisdiction,” art. III, § 2, cl.1, “saving to suitors in all cases all other remedies to which
2 they are otherwise entitled.” 28 U.S.C. 1333(1). To determine whether maritime jurisdiction
3 exists over a claim, courts analyze three factors: (1) “whether the tort occurred on navigable water
4 or whether injury suffered on land was caused by a vessel on navigable water”; (2) “whether the
5 incident has ‘a potentially disruptive impact on maritime commerce’”; and (3) “whether ‘the
6 general character’ of the ‘activity giving rise to the incident’ shows a ‘substantial relationship to
7 traditional maritime activity.’” Earth Island Inst. v. Crystal Geyser Water Co., 521 F. Supp. 3d
8 863, 879 (N.D. Cal. 2021) (quoting Jerome B. Grubart, Inc. v. Great Lakes Dredge & Dock Co.,
9 513 U.S. 527, 534 (1995)). Even if this analysis supports maritime jurisdiction, the “saving to
10 suitors” clause that Congress enacted “leave[s] state courts ‘competent’ to adjudicate maritime
11 causes of action in proceedings ‘in personam,’ that is, where the defendant is a person, not a ship
12 or some other instrument of navigation.” Ghotra by Ghotra v. Bandila Shipping, Inc., 113 F.3d
13 1050, 1054 (9th Cir. 1997) (quoting Madruga v. Superior Ct. of Cal., 346 U.S. 556, 560–61
14 (1954)). “This means that when a plaintiff brings a maritime cause of action against a person in
15 state court, a federal court lacks admiralty jurisdiction over that claim” unless the defendant
16 “assert[s] some other basis of jurisdiction.” Cnty. of San Mateo v. Chevron Corp., 32 F.4th 733,
17 763 (9th Cir. 2022) (hereafter “San Mateo II”).
18 C. Federal Enclaves
19 “Federal enclave jurisdiction refers to the principle that federal law applies in federal
20 enclaves.” City & Cnty. of Honolulu v. Sunoco LP, 39 F.4th 1101, 1111 (9th Cir. 2022) (citing
21 U.S. Const. art. I, § 8, cl. 17). Such enclaves arise “when the federal government purchases state
22 land with the consent of the state legislature,” because at that point “any law existing on that land
23 must derive its authority and force from the United States and is for that reason federal law.”
24 San Mateo II, 32 F.4th at 749 (internal quotation marks omitted). For federal enclave
25 jurisdiction to apply, such an enclave must be the “locus” of the claim. Honolulu, 39 F.4th at
26 1111.
27 Where a basis for removal is rooted in a federal question, as is the case with Exxon’s
1 federal jurisdiction exists only when a federal question is presented on the face of the plaintiff's
2 properly pleaded complaint.” In re NOS Commc’ns, MDL No. 1357, 495 F.3d 1052, 1057 (9th
3 Cir. 2007) (quoting Caterpillar Inc. v. Williams, 482 U.S. 386, 392 (1987)). Generally speaking,
4 a plaintiff “may avoid federal jurisdiction by exclusive reliance on state law,” Caterpillar, 482
5 U.S. at 392, but at the same time, “a plaintiff may not defeat removal by omitting to plead
6 necessary federal questions in a complaint.” Lippitt v. Raymond James Fin. Servs., Inc., 340
7 F.3d 1033, 1041 (9th Cir. 2003).
8 D. Federal Officer
9 Under the statute that provides for federal officer removal, defendants may remove a
10 “civil action . . . that is against or directed to . . . [t]he United States or any agency thereof or any
11 officer (or any person acting under that officer) . . . in an official or individual capacity, for or
12 relating to any act under color of such office.” 28 U.S.C. § 1442(a)(1). To demonstrate that this
13 requirement is met, “Defendants must show: (1) they were “acting under” federal officers, (2)
14 they can assert a colorable federal defense, and (3) Plaintiffs’ injuries were for or relating to
15 Defendants’ actions.” Honolulu, 39 F.4th at 1106.
16 E. Younger abstention and the Colorado River Doctrine
17 As for the Nonprofit Plaintiffs’ suit, it is undeniably subject to federal jurisdiction due to
18 diversity of citizenship. As a result, the Nonprofit Plaintiffs urge the court to abstain from
19 hearing this case pursuant to either the Younger or Colorado River line of cases.
20 Younger abstention is grounded in a “longstanding public policy against federal court
21 interference with state court proceedings.” Herrera v. City of Palmdale, 918 F.3d 1037, 1043–
22 44 (9th Cir. 2019) (quoting Younger v. Harris, 401 U.S. 37, 43 (1971)). Under this doctrine,
23 federal courts may abstain when a case concerns “(1) parallel, pending state criminal
24 proceedings, (2) state civil proceedings that are akin to criminal prosecutions, and (3) state civil
25 proceedings that implicate a State’s interest in enforcing the orders and judgments of its courts.”
26 ReadyLink Healthcare, Inc. v. State Comp. Ins. Fund, 754 F.3d 754, 759 (9th Cir. 2014) (internal
27 quotation marks and citations omitted). First identified in New Orleans Public Service, Inc. v.
1 categories. See Sprint Commc’ns, Inc. v. Jacobs, 571 U.S. 69, 72–73 (2013). To warrant
2 Younger abstention in a federal case, the ongoing state case must fall into one of the NOPSI
3 categories and provide “an adequate opportunity . . . to raise constitutional challenges.” Bean v.
4 Matteucci, 986 F.3d 1128, 1133 (9th Cir. 2021) (internal quotation marks and citation omitted).
5 Moreover, the requested relief in the federal case must “seek[] to enjoin or ha[ve] the practical
6 effect of enjoining the ongoing state judicial proceeding.” Id. (internal quotation marks omitted).
7 Distinct from Younger abstention, the Colorado River doctrine provides that, in rare
8 cases, “there are principles unrelated to considerations of proper constitutional adjudication and
9 regard for federal-state relations which govern in situations involving the contemporaneous
10 exercise of concurrent jurisdictions, either by federal courts or by state and federal courts.”
11 Colorado River Water Conservation Dist. v. United States, 424 U.S. 800, 817 (1976). “In the
12 interest of ‘[w]ise judicial administration, giving regard to conservation of judicial resources and
13 comprehensive disposition of litigation,’ a district court can dismiss or stay ‘a federal suit due to
14 the presence of a concurrent state proceeding.’” United States v. State Water Res. Control Bd.,
15 988 F.3d 1194, 1202 (9th Cir. 2021) (quoting Colorado River, 424 U.S. at 817–18)). “The
16 instances in which a court can stay an action pursuant to Colorado River ‘are considerably more
17 limited than the circumstances appropriate for abstention. The former circumstances, though
18 exceptional, do nevertheless exist.’” Id. (quoting Colorado River, 424 U.S. at 817–18).
19 IV.DISCUSSION AS TO CALIFORNIA CLAIMS
20 In cases like California’s, where a removed action involves state law claims against a
21 person in state court such that maritime jurisdiction only exists if there is an independent
22 jurisdictional basis, a court may first examine the alternative bases for removal. See, e.g., San
23 Mateo II, 32 F.4th at 763 (examining whether maritime jurisdiction exists only after determining
24 whether the asserted independent bases for such jurisdiction were present). As applied to
25 California’s instant motion, San Mateo II counsels in favor of starting with Defendant’s
26 arguments as to federal enclave and federal jurisdiction before addressing maritime law.
27
1 A. Federal Enclave
2 To support its assertion of federal enclave jurisdiction, Exxon highlights that the state’s
3 complaint asserts damages to California’s “waterways” and their “shorelines,” see Complaint
4 ¶ 60—a vast expanse which necessarily must include a few federal enclaves. Exxon also points
5 to the complaint’s description of pollution in Monterey Bay, a recognized federal enclave, as
6 proof that such jurisdiction exists. See id. ¶ 360. Plaintiffs urge the court to reject this argument,
7 given that the complaint expressly disclaims injuries arising on federal lands, which would
8 include federal enclaves, and that it does not seek any relief relating to such injuries. Id. n.1.
9 Exxon’s argument is misguided, to say the least. Even as it concedes that the complaint
10 disclaims injuries or relief on all federal lands, Exxon nevertheless contends that, because some
11 California waterways have been deemed federal enclaves in other contexts, California’s claims
12 necessarily have a federal enclave locus. California, however, is “‘the master[]s of the claim.’”
13 City of Oakland v. BP PLC, 969 F.3d 895, 904 (9th Cir. 2020) (quoting Caterpillar Inc. v.
14 Williams, 482 U.S. 386, 392 (1987)). An express disclaimer is “sufficient to eviscerate [a
15 defendant’s] grounds for removal.” Hukkanen v. Air and Liquid Systems Corp., No. 170-cv-
16 02227-JFW, 2017 WL 1217075, at *2 (C.D. Cal. March 31, 2017). By bringing only state
17 claims in a state court, and expressly disavowing injuries on federal lands, the state has
18 established that neither claims nor relief could lie in federal enclaves, let alone have such
19 enclaves as their loci.
20 Even were the court to ignore California’s express disclaimer, Defendant nevertheless
21 would fail to establish that the loci of the at-issue claims are in federal enclaves. See, e.g.,
22 Ballard v. Ameron Int'l Corp., No. 16-cv-06074-JSC, 2016 WL 6216194, at *3 (N.D. Cal. Oct.
23 25, 2016) (denying removal in asbestos exposure case where, inter alia, only one of seventeen
24 exposure sites was a federal enclave). It is not as if “federal enclave doctrine applies as long as
25 some of the alleged events occurred on the federal enclave.”5 In re High-Tech Empl. Antitrust
26
5 Exxon misstates the law when it suggests that “the locus test is satisfied as long as ‘at least some
27
of the[] locations’ where the tortious harm occurred are ‘federal enclaves.’” Opp. Br. at 14 (citing
1 Litig., 856 F. Supp. 2d 1103, 1125 (N.D. Cal. 2012). Simply because plastic pollution touches
2 on federal enclaves does not mean California’s claims have their loci there; to the contrary, the
3 claims concern the cultural messaging and corporate decision-making that Exxon allegedly
4 engaged in when promoting the use of recycling as a cure-all to plastic waste.
5 In making this doomed argument, Exxon strives to distinguish San Mateo II and
6 Honolulu—two cases where the Ninth Circuit roundly rejected fossil fuel defendants’ arguments
7 for federal enclave jurisdiction in similar pollution-related claims—by highlighting the way
8 those defendants argued for conduct-based enclave jurisdiction, rather than the injury-based
9 enclave jurisdiction Exxon raises here. This distinction makes no difference. At bottom, the
10 Ninth Circuit has twice rebuffed the broad reading of federal enclave jurisdiction that Exxon
11 nevertheless asserts. See Honolulu, 39 F.4th at 1111 (“Federal enclave jurisdiction needs a direct
12 connection between the injury and conduct.”); see also San Mateo II, 32 F.4th at 750. Under
13 these precedents, federal enclave jurisdiction is lacking in this case.
14 B. Federal Officer
15 Exxon’s argument for federal officer jurisdiction revolves around rubber. Because the
16 United States government contracted with Exxon’s predecessors to produce rubber for World
17 War II-era military use, the company claims the existence of “a causal nexus between its actions,
18 taken pursuant to a federal officer’s directions, and [the] plaintiff’s claims. San Mateo II, 32
19 F.4th at 755.
20 This claim verges on the fanciful. Rubber is not the product at issue in the complaint—
21 plastic is. As California notes, the only mention of rubber in their allegations is to its use in
22 advanced recycling processes that Exxon allegedly promotes in a deceptive and plastic-pollution-
23 inducing fashion. See Complaint ¶ 267 (describing how “waste tires” are used as feedstock in
24 certain recycling procedures). Defendant protests that the “millions of tons of synthetic rubber
25

26
federal enclaves—the only asserted exposures that might not have occurred on federal enclaves
included cities in Tokyo, Korea, and Germany. See 2012 WL 1110001, at *2. Indeed, that case
27
did not even discuss the locus test, instead recognizing that “personal injury actions which arise
1 that ExxonMobil helped produce at the direction of the federal government contributed to—and
2 thus ‘relate to’—this alleged pollution crisis.” Opp. 24. What Defendant appears to sidestep,
3 however, is that the claims in this case are not about pollution in the abstract; they concern
4 Exxon’s allegedly self-interested and deceptive promotion of plastics recycling programs that it
5 knew would fail to prevent the current pollution crisis.
6 Defendant also claims that, if it is the largest contributor to plastic waste in California, “it
7 is only because ExxonMobil ascended to industry leadership following its joint efforts with the
8 government to exponentially grow the synthetic-rubber industry during World War II.” Opp. at
9 25. Putting the self-congratulations for winning the war to one side, this argument misses the
10 boat entirely. Plaintiffs allege Exxon promoted a deceptive marketing campaign to deceive the
11 public about plastic. Whether Exxon’s predecessors’ past partnership with the United States
12 military to produce a completely different substance (i.e., rubber) also contributed to pollution is
13 completely tangential to the complaint.
14 Even if it were possible to look past the severe disconnect in Defendant’s premise, its
15 argument for federal officer jurisdiction would still flunk the merits. First, nothing suggests that
16 “the challenged acts occurred because of what [Exxon] w[as] asked to do by the government.”
17 See Goncalves v. Rady Children’s Hospital. San Diego, 865 F.3d 1237, 1245 (9th Cir. 2017)
18 (internal quotation marks omitted). There could not be a wider mismatch between the purported
19 federal directions regarding synthetic rubber production and the deceptive conduct California
20 raises in its complaint.
21 As for the colorable federal defense showing necessary to a federal officer removal,
22 Exxon likewise falls flat. It suggests that a federal contractor immunity defense as to
23 California’s plastics-related claims is viable because the federal government specified the details
24 of its wartime synthetic rubber production. As just explained, however, that argument fails to
25 track the complaint’s actual claims, which involve deception about plastic, not the production of
26 rubber. At bottom, and much like its arguments for federal enclave jurisdiction, Exxon’s
27 asserted rationale for federal officer jurisdiction is completely baseless.
1 C. Maritime Law
2 Exxon also asserts admiralty or maritime jurisdiction under 28 U.S.C. § 1333 because at
3 least some of California’s asserted injuries occurred in navigable waters.
4 In San Mateo II, the Ninth Circuit rejected a similar argument because “maritime claims
5 brought in state court are not removable to federal court absent an independent jurisdictional
6 basis.” 32 F.4th at 763. As explained above, no independent jurisdictional basis supports the
7 removal of California’s complaint. Thus, “[e]ven assuming that [California’s] claims in this case
8 qualify as maritime claims, [California] chose to bring these claims in state court. Under the
9 ’saving to suitors’ clause, these maritime claims are not removable to federal court based on
10 admiralty jurisdiction alone.” Id.
11 At oral argument, Exxon’s counsel argued that California waived argument about the
12 saving to suitors clause by not raising it until the reply brief. For support, counsel cited Morris v.
13 Princess Cruises, Inc., where the Ninth Circuit noted that “a state plaintiff may waive the
14 improper removal of a savings clause claim.” 236 F.3d 1061, 1069 (2001). In that case,
15 however, the state plaintiff “fail[ed] to seek remand . . . of claims falling within the court’s
16 admiralty jurisdiction.” Id. Quite the opposite occurred here, where—assuming that such
17 jurisdiction exists—California does seek remand. It repeatedly cited San Mateo II in its motion,
18 putting Exxon on notice that the case would inform the remand analysis. Thus, Exxon’s failure
19 to address the saving to suitors discussion that anchored San Mateo II’s holding as to maritime
20 jurisdiction does not raise the same fairness concerns that might occur in the situation where a
21 plaintiff raises an unexpected new argument on reply.
22 Even accepting the dubious premise that the saving to suitors clause should not factor
23 into the remand decision, California’s claims are not maritime in nature. In arguing to the
24 contrary, Exxon must first satisfy the location test by showing the relevant torts occurred on
25 navigable water or a vessel on navigable water caused injury suffered on land. See Grubart, 513
26 U.S. at 534. The latter showing is foreclosed, given that nothing in the complaint concerns
27 vessels, let alone vessels causing harm on land. As for the first showing, it is true that California
1 See, e.g., Complaint ¶ 449–54. Yet, a close reading of the claims reveals that the alleged tort is
2 “deception,” not the actual depositing of plastic into navigable water. See id. ¶ 453; see also id.
3 ¶ 427 (explaining the alleged conduct supporting the state’s public nuisance claim), ¶ 443 (same
4 as to state’s pollution of natural resources claim). That deception did not occur in navigable
5 water. In this regard, California’s claims are easily distinguishable from the sort of oil spill
6 claims that courts have considered to satisfy the location test. See, e.g., United States v. City of
7 Redwood City, 640 F.2d 963, 969 (9th Cir. 1981).
8 Exxon fares no better on the connection test, which requires showing “a substantial
9 relationship between the activity giving rise to the incident and traditional maritime activity.”
10 Sisson v. Ruby, 497 U.S. 358, 364 (1990). “The relevant ‘activity’ is defined not by the
11 particular circumstances of the incident, but by the general conduct from which the incident
12 arose.” Id.; see also Executive Jet Aviation, Inc. v. City of Cleveland, 409 U.S. 249, 253–54
13 (1972) (holding that, in a case where the alleged harm involved a plane sinking in Lake Erie, the
14 relevant activity was air travel, which did not bear a significant relationship to traditional
15 maritime activity). Here, the activity giving rise to the alleged injuries is Exxon’s allegedly
16 deceptive conduct, which does not bear a substantial relationship to traditional maritime activity.
17 At bottom, “[p]ermitting Defendant[] to manufacture federal jurisdiction here using doctrines
18 such as maritime law would abrogate the principle that a plaintiff is ‘master of the claim.’”
19 Earth Island, 521 F. Supp. 3d at 880 (quoting Caterpillar, 482 U.S. at 392).
20 D. Conclusion as to California Suit
21 Because neither federal enclave nor federal officer jurisdiction extends over California’s
22 claims, Exxon cannot show the independent basis required for maritime jurisdiction to apply
23 pursuant to the saving to suitors clause. Moreover, maritime jurisdiction would be inapplicable
24 anyway. California’s motion to remand is therefore granted.
25 V.DISCUSSION AS TO NONPROFITS’ CLAIM
26 Federal jurisdiction over Nonprofit Plaintiffs’ complaint is on sure footing, given their
27 concession that diversity jurisdiction is proper. Nonprofit Plaintiffs nevertheless urge the court
1 to remand their case alongside the California action, arguing for either Younger abstention or a
2 creative application of the Colorado River doctrine.
3 Younger abstention is not warranted in this instance. To be sure, there is an ongoing state
4 civil proceeding akin to a criminal prosecution: the California action, which has now been
5 remanded to state court and which was still in state court at the time Exxon removed Nonprofit
6 Plaintiffs’ complaint. Brought by the state attorney general to abate an alleged nuisance,
7 California’s case amounts to a quasi-criminal enforcement proceeding. See Huffman v. Pursue,
8 Ltd., 420 U.S. 592, 604–5 (1975) (finding public nuisance abatement action eligible for Younger
9 abstention). That action by the state under state laws clearly implicates important state interests,
10 and there is no reason to think Exxon would be unable to raise constitutional challenges.
11 That said, to abstain from exercising the jurisdiction that indisputably applies to this case,
12 such exercise would have to raise the risk of “enjoining the ongoing state judicial proceeding”
13 initiated by California. See Bean, 986 F.3d at 1133. Here, no such risk exists. For one thing,
14 Nonprofit Plaintiffs could always voluntarily dismiss their claims if concerned that federal court
15 decisions will raise res judicata problems in California’s case. For another, federal courts and
16 state courts regularly adjudicate closely related claims in parallel. “The Supreme Court has
17 rejected the notion that federal courts should abstain whenever a suit involves claims or issues
18 simultaneously being litigated in state court merely because whichever court rules first will, via
19 the doctrines of res judicata and collateral estoppel, preclude the other from deciding that claim
20 or issue.” AmerisourceBergen Corp. v. Roden, 495 F.3d 1143, 1151 (9th Cir. 2007).
21 “Concurrent consideration, not abstention, is the solution.” Id.
22 Colorado River is also inapplicable to the instant request. “Plaintiff’s briefing does not
23 direct the Court to any caselaw, nor can the Court identify any controlling authority, where a
24 district court relied on Colorado River doctrine to remand a case properly removed under diversity
25 jurisdiction.” Stapleton v. Idanks Ltd. Liab. Co., No. 6:24-cv-00056-MK, 2024 WL 1939499, at
*3 (D. Or. Mar. 22, 2024), report and recommendation adopted sub nom. Stapleton v. Just My
26
Kicks LLC, 2024 WL 1932612 (D. Or. May 1, 2024). As another court recognized, “[n]o binding
27
1 No. 23-cv-00435 JAO-BMK, 2024 WL 4456803, at *18 n.12 (D. Haw. Apr. 5, 2024).
2 At oral argument, Nonprofit Plaintiffs acknowledged that the Ninth Circuit has never
3 blessed a Colorado River remand but raised the example of Abend v. City of Oakland, No. 06-cv-
4 07459 JSW, 2007 WL 627916 (N.D. Cal. Feb. 26, 2007). There, a district court found remand
appropriate pursuant to the Colorado River doctrine. Id. at *5. No appeal followed, so it remains
5
unclear whether the remand would have been affirmed.6 At any rate, the facts in that case are
6
distinct; a city had initiated state nuisance proceedings against a shopping center’s owners, and the
7
owners responded by filing a state action (which the city subsequently removed) alleging
8
constitutional violations and seeking to enjoin the city’s suit. Id., at *1-2. The owners even
9
sought to consolidate the city’s nuisance action and their responsive constitutional claims at the
10
state court, only to be rebuffed when the city chose to remove the constitutional claims instead.
11
Id., at *5. In that regard, the situation more closely resembles that which occurred in Nakash v.
12
Marciano, 882 F.2d 1411, 1416 (9th Cir. 1989), where the Ninth Circuit affirmed a district court
13
decision to stay a federal action removed by a defendant who was the plaintiff in a related state
14
proceeding. Such role reversal is completely absent here, where Exxon is the defendant in
15
California’s case and in Nonprofit Plaintiffs’ case, and where the Nonprofit Plaintiffs’ sought-after
16
relief cannot possibly conflict with California’s ongoing state proceedings (given that it is
17
essentially the same relief that California seeks).
18
Because no binding authority exists for a Colorado River remand, and because the only
19 relevant precedent is both distinguishable and possibly incorrect, Nonprofit Plaintiffs fail to
20 persuade that Colorado River is applicable in the instance context. A factor-by-factor analysis is
21 therefore unwarranted, and the motion to remand is denied.
22 VI.CONCLUSION
23 For the reasons explained above, California’s case against Exxon is remanded to the state
24 court from whence it came; neither maritime, federal enclave, nor federal officer jurisdiction
25
6 Motivating the Abend decision was the court’s concern about “risk[ing] inconsistent rulings”
26
with the state proceedings. 2007 WL 627916, at *4. As discussed with regard to Younger
abstention, however, the risk of inconsistent rulings between state and federal courts does not
27
override “the virtually unflagging obligation of the federal courts to exercise the jurisdiction given
1 applies to its claims. The same holds true for Nonprofit Plaintiffs’ claims, but because of the
2 || diversity jurisdiction that undeniably applies, their motion to remand is denied. Younger
3 abstention and/or the invocation of Colorado River is unwarranted in this instance.
4 At oral argument, Exxon’s counsel requested a short stay of any remand order so as to
5 sort out whether a longer stay pending appeal might be warranted. California’s counsel
6 apparently stipulated to that idea. A short administrative stay is therefore appropriate, and the
7 || remand order as to California’s case is stayed until 42 days after this ruling. Within 7 days of
8 this ruling, the parties must submit a stipulated briefing schedule for addressing the propriety of a
9 stay pending appeal. The parties should assume that any further stay request will be decided on
10 || the papers, with a hearing to be scheduled only if necessary.
11
12 IT IS SO ORDERED.
