Opinion

EMMALIE SEIJAS, et al., No. 2:24-cv-03423-DJC-AC Plaintiff, v. ORDER THE JACKSON LABORATORY, et al., Defendants.

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