UNITED STATES DISTRICT COURT EASTERN DISTRICT OF KENTUCKY SOUTHERN DIVISION LONDON KEITH HARRIS, et ux., ) ) Plaintiffs, ) No. 6:25-CV-234-REW-CJS ) v. ) ) OPINION & ORDER 3M COMPANY, et al., ) ) Defendants. )

*** *** *** *** Keith and Whitney Harris (collectively, “Plaintiffs”) filed a product liability suit against 3M Company (“3M”), Moldex-Metric, Inc. (“Moldex”), Kentucky Mine Supply Company (“KMS”), and Mine Service Company, Inc. (“MSC”) (collectively, “Defendants”) in Kentucky state court. See generally DE 1-3. More than two years later, 3M filed a notice of removal, premised on diversity, with this Court. See generally DE 1. 3M alleges that KMS and MSC— Kentucky-based parties—were fraudulently joined and that Plaintiffs litigated against them in bad faith. See id. at 6–10, 17–21. Following 3M’s notice of removal, Plaintiffs filed a motion to remand and for sanctions to be imposed against 3M. See DE 12; see also DE 13. In response, 3M reiterated its previous contentions. See DE 16. Plaintiffs subsequently filed a reply. See DE 19. The Court declines the invitation to scrutinize whether KMS and MSC were fraudulently joined, as that inquiry is inappropriate given the passage of the applicable one-year removal deadline. More foundationally, the Court declines to find that Plaintiffs have acted in bad faith in order to prevent removal. Accordingly, the Court grants Plaintiffs’ request for remand. But because Plaintiffs failed to comply with Rule 11’s procedural requirements, the Court denies the sanctions request. As a result, DE 12 is GRANTED, in part. The case is remanded. I. BACKGROUND On November 16, 2022, Plaintiffs initiated the present action in Kentucky state court. See generally DE 1-3. The complaint alleges that Keith Harris—a former coal miner domiciled in Kentucky—suffers from coal workers’ pneumoconiosis and/or silicosis. See id. ¶¶ 8–10, at 4–5.

It further alleges that, while employed as a coal miner, Keith Harris was provided with defective respirators that were produced and manufactured by 3M and Moldex (collectively, “the manufacturer defendants”). See id. ¶¶ 11–15, at 5–6. The complaint states that those respirators were distributed to Keith Harris by his employers after being sold to his employers by KMS and MSC (collectively, “the distributor defendants”). See id. ¶ 13, at 5. Notably, 3M has impleaded a number of Keith Harris’s former employers as third-party defendants. See DE 16 at 10–12. Whitney Harris—Keith’s spouse—has also joined the action, bringing a loss of consortium claim against Defendants. See DE 1-3 ¶¶ 68–74, at 19–20. The parties do not dispute that 3M is incorporated in Delaware with its principal place of business in Minnesota, that Moldex is incorporated in California with its principal place of business in California, and that both KMS

and MSC are incorporated in Kentucky with their principal places of business in Kentucky. See id. ¶¶ 2–5, at 3–4; DE 1 at 2, 6. Three additional events are relevant to deciding the present motion. First, MSC filed an answer denying (vaguely, perhaps) Plaintiffs’ allegation that it supplied Keith Harris’s employers with the allegedly faulty respirators; MSC phrased the denial as “to the extent that [Plaintiffs] allege[d] or infer[red] negligence and/or liability and/or wrongdoing on the part of MSC.” See DE 19-1 at ¶ 4, at 2. This echoed MSC’s separate self-characterization in the answer, where it stated that it “distributed mining supplies some of which, from time-to-time, may have included dust masks . . . manufactured by 3M,” but that it “denies all allegations of negligence and/or liability and/or wrongdoing.” See id. ¶2, at 1. Second, in response to the plaintiffs’ interrogatories in Wilson v. 3M Company (22-CI-812), a distinct mask case, MSC asserted that: (1) “it sold respiratory protective equipment manufactured by 3M” between 1979 and 2012; (2) “to the best of its recollection it sold mine supplies to Excel Mining, LLC,” Keith Harris’s employer; and (3) it

had “no documents in its possession which would demonstrate whether or not the[] mine supplies included respiratory equipment.” See DE 13-2 at 1–2, 4–5. Third, on the last day of discovery in the state matter, MSC responded to 3M’s requests for admissions and admitted that it never sold respirators to Keith Harris’s employers. See DE 1-11 at 2–4. Ultimately, this case was set for trial in state court on September 22, 2025. See DE 1 at 5; DE 13 at 1. However, on May 23, 2025—the day that fact discovery concluded and the same day that MSC responded to 3M’s requests for admission—3M filed a notice of removal with this Court. See generally DE 1. In its notice of removal, 3M alleged that the parties properly joined are completely diverse and that all other requirements for the Court to exercise diversity jurisdiction are satisfied. See id. at 5–6. Although the distributor defendants are Kentucky corporations (which

would facially defeat complete diversity on account of Plaintiffs’ Kentucky citizenship), 3M asserts that they were fraudulently joined and/or joined in bad faith. See id. at 6–10, 17–21. A few days after removal, Plaintiffs filed the instant motion, see generally DE 12, along with an accompanying memorandum, see generally DE 13. In their motion, Plaintiffs (1) ask the Court to remand the action to state court, arguing that the distributor defendants were not fraudulently joined and that they have not litigated against the distributor defendants in bad faith, see DE 13 at 10–15, and (2) request that sanctions be imposed against 3M in accordance with Federal Rule of Civil Procedure 11 on account of 3M’s filing of an improper notice of removal, see id. at 15–16. Plaintiffs did not file their motion for sanctions separately from their motion for remand, see generally DE 12; DE 13, and the record does not indicate that they served the motion on 3M prior to filing it with the Court, see DE 16 at 19–20.1 In its response, 3M generally reasserts its fraudulent joinder and bad faith claims. See id. at 4–18. Plaintiffs filed a reply. See DE 19. The matter is ripe for the Court’s decision.

II. STANDARD OF REVIEW A. Removal and Federal Jurisdiction Federal courts are courts of limited jurisdiction, only possessing the power to hear cases upon specific statutory and constitutional authorization. See Kokkonen v. Guardian Life Ins. Co. of Am., 114 S. Ct. 1673, 1675 (1994) (citing Willy v. Coastal Corp., 112 S. Ct. 1076, 1080 (1992); Bender v. Williamsport Area Sch. Dist., 106 S. Ct. 1326, 1331 (1986)). Notably, federal district courts “have original jurisdiction of all civil actions where the matter in controversy exceeds the sum or value of $75,000, exclusive of interest and costs, and is between . . . citizens of different States.” 28 U.S.C. § 1332(a); see also U.S. CONST. art. III, § 2, cl. 1. Courts have consistently held that “complete diversity” is necessary for diversity jurisdiction, meaning that all plaintiffs

must be of diverse citizenship from all defendants. See, e.g., U.S. Motors v. Gen. Motors Eur., 551 F.3d 420, 423 (6th Cir. 2008). An individual’s citizenship is defined by their place of domicile, i.e., where they reside and intend to remain, see Mason v. Lockwood, Andrews & Newman, P.C., 842 F.3d 383, 390 (6th Cir. 2016) (citing Miss. Band of Choctaw Indians v. Holyfield, 109 S. Ct. 1597, 1608 (1989)), while a corporation’s citizenship is defined by its principal place of business and the state in which it is incorporated, see Hertz Corp. v. Friend, 130 S. Ct. 1181, 1185 (2010) (citing 28 U.S.C.
