Opinion

1 2 3 4 5 6 7 8 UNITED STATES DISTRICT COURT 9 FOR THE EASTERN DISTRICT OF CALIFORNIA 10 11 EMMALIE SEIJAS, et al., No. 2:24-cv-03423-DJC-AC 12 Plaintiff, 13 v. ORDER 14 THE JACKSON LABORATORY, et al., 15 Defendants. 16

17 Plaintiff Emmalie Seijas filed this case as a class action in California state court, 18 and Defendants removed the case to this Court under the Class Action Fairness Act 19 (“CAFA”). Pending before the Court is Plaintiff’s Motion to Remand (ECF No. 21), 20 which argues Defendants failed to establish the requisite amount in controversy for 21 CAFA jurisdiction. For the reasons stated below, remand is denied. 22 BACKGROUND 23 Plaintiff Emmalie Seijas filed this case on behalf of herself and other employees 24 similarly situated against Defendants in the Superior Court for the County of 25 Sacramento. Plaintiff alleges failure to pay overtime and minimum wages, provide or 26 compensate for missed meal and rest breaks, and reimburse business-related costs as 27 well as waiting time penalties and wage statement violations. (FAC ¶¶ 68–148.) 28 Based on these allegations, Plaintiff brings claims under the California Unfair 1 Competition Law (UCL), Cal. Bus. & Profs. Code §§ 17200, et seq.; Cal. Lab. Code 2 §§ 510, 1198, 226.7, 512(a), 1194, 1197, 1197.1, 201, 202, 204, 226(a), 1174(d), 2800, 3 and 2802. 4 Defendants timely removed this action under CAFA, codified at 28 U.S.C. 5 § 1332(d). (See Not. Removal (ECF No. 1).) Plaintiff then moved to remand this action. 6 (See Mot. (ECF No. 21)). Briefing on Plaintiff’s Motion to Remand is now complete. 7 (Mot. (ECF No. 21); Opp’n (ECF No. 22); Reply (ECF No. 23).) The Court heard 8 argument on this Motion on October 16, 2025. Dominic Scarangella appeared for 9 Plaintiff, and Jeffrey Nordlander appeared for Defendant. The Motion was taken 10 under submission. (See ECF No. 27.) 11 DISCUSSION 12 I. Legal Standard 13 “[A]ny civil action brought in a State court of which the district courts of the 14 United States have original jurisdiction, may be removed by the defendant or the 15 defendants, to the district court of the United States for the district . . . where such 16 action is pending.” 28 U.S.C. § 1441(a). Under CAFA, the federal courts have original 17 jurisdiction over class actions in which the parties are minimally diverse, the proposed 18 class has at least 100 members, and the aggregated amount in controversy exceeds 19 $5 million. See 28 U.S.C. § 1332(d)(2), (d)(5)(B). 20 A defendant removing a class action filed in state court pursuant to CAFA need 21 only plausibly allege in the notice of removal that the CAFA prerequisites are satisfied. 22 Dart Cherokee Basin Operating Co., LLC v. Owens, 574 U.S. 81, 89 (2014). However, 23 the plaintiff can then contest the amount in controversy by making either a “facial” or 24 “factual” attack on the defendant's jurisdictional allegations. Harris v. KM Indus., Inc., 25 980 F.3d 694, 699 (9th Cir. 2020). “A facial attack accepts the truth of the 26 [defendant's] allegations but asserts that they are insufficient on their face to invoke 27 federal jurisdiction.” Id. (internal quotation marks omitted) (quoting Leite v. Crane Co., 28 749 F.3d 1117, 1121 (9th Cir. 2014)). A factual attack, on the other hand, contests the 1 truth of the allegations themselves. Id. When a plaintiff mounts a factual attack, they 2 “need only challenge the truth of the defendant's jurisdictional allegations by making 3 a reasoned argument as to why any assumptions on which they are based are not 4 supported by evidence.” Id. at 700. 5 “When a plaintiff mounts a factual attack, the burden is on the defendant to 6 show, by a preponderance of the evidence, that the amount in controversy exceeds 7 the $5 million jurisdictional threshold.” Id. at 699. Specifically, when a plaintiff's 8 complaint does not quantify damages, defendants must show that the amount in 9 controversy exceeds the jurisdictional threshold by a preponderance of the evidence. 10 See Canela v. Costco Wholesale Corp., 971 F.3d 845, 849 (9th Cir. 2020). A defendant 11 “is only required to show that it is more likely than not that Plaintiff’s maximum 12 recovery reasonably could be over $5 million.” Avila v. Rue21, Inc., 432 F. Supp. 3d 13 1175, 1185 (E.D. Cal. 2020). This burden is not daunting as “a removing defendant is 14 not obligated to research, state, and prove the plaintiff's claims for damages.” Korn v. 15 Polo Ralph Lauren Corp., 536 F. Supp. 2d 1199, 1204–05 (E.D. Cal. 2008) (internal 16 quotation marks omitted). 17 Rather, in making this showing, a removing defendant “must be able to rely ‘on 18 a chain of reasoning that includes assumptions.’” Jauregui v. Roadrunner 19 Transportation Servs., Inc., 28 F.4th 989, 993 (9th Cir. 2022) (quoting LaCross v. Knight 20 Transp. Inc., 775 F.3d 1200, 1201 (9th Cir. 2015)); see also Jauregui, 28 F.4th at 993 21 (explaining that a “CAFA defendant's amount in controversy assumptions in support 22 of removal will always be just that: assumptions”). These assumptions must reflect 23 more than “mere speculation and conjecture.” Ibarra v. Manheim Invs., Inc., 775 F.3d 24 1193, 1197 (9th Cir. 2015). Such assumptions require “some reasonable ground 25 underlying them,” id. at 1199, but they “need not be proven.” Arias v. Residence Inn 26 by Marriott, 936 F.3d 920, 927 (9th Cir. 2019). Assumptions may be reasonable if they 27 are “founded on the allegations of the complaint.” Id. at 925. Parties may also “submit 28 evidence outside the complaint, including affidavits or declarations, or other 1 summary-judgment type evidence.” See Ibarra, 775 F.3d at 1197 (internal quotation 2 marks omitted). 3 “If at any time before final judgment it appears that the district court lacks 4 subject matter jurisdiction, the case shall be remanded.” 28 U.S.C. § 1447(c). The 5 Supreme Court has advised, however, “that no antiremoval presumption attends 6 cases invoking CAFA” in part because the statute was enacted “to facilitate 7 adjudication of certain class actions in federal court.” Dart Cherokee, 574 U.S. at 89 8 (citations and quotations marks omitted). “CAFA's provisions should be read broadly, 9 with a strong preference that interstate class actions should be heard in a federal court 10 if properly removed by any defendant.” Id. (internal quotation marks omitted); see 11 also Ibarra, 775 F.3d at 1197. 12 II. Analysis 13 The Parties do not dispute that they are diverse or that the proposed class has 14 at least 100 members. The only issue before the Court is whether the amount in 15 controversy exceeds $5 million. 16 A. Plaintiff Brings a Factual Challenge to Jurisdiction 17 Plaintiff contests the truth of Defendants’ allegations in the Notice of Removal.
