PROCEEDINGS: (IN CHAMBERS): ORDER TO SHOW CAUSE RE DISMISSAL FOR LACK OF SUBJECT MATTER JURISDICTION

The Complaint in this action was filed on October 24, 2023, alleging jurisdiction on the basis of diversity jurisdiction pursuant to

. (Dkt. (“Compl.”).) However, it appears the court may lack subject matter jurisdiction because the Complaint does not adequately allege diversity of citizenship between all parties. (See id.)

Courts “have an independent obligation to determine whether subject-matter jurisdiction exists, even in the absence of a challenge from any party.” Arbaugh v. Y&H Corp.,

(2006) (citation omitted). Diversity jurisdiction requires complete diversity between the parties and that the amount in controversy exceeds $75,000. See Strawbridge v. Curtiss,

(1806);

(a). In the case of a partnership, limited liability company, or other unincorporated association, the court must consider the citizenship of each of the partners, including limited partners, or members. The citizenship of each of the entity’s partners or members must therefore be alleged. Carden v. Arkoma Assocs.,

(1990); Johnson v. Columbia Props. Anchorage, LP,

(9th Cir. 2006). Where a party is joined as a corporation, the complaint must allege both its respective state(s) of incorporation and principal place of business.

(c); Harris v. Rand,

(9th Cir. 2012). A natural person’s state citizenship is determined by their state of domicile. Kanter v. Warner-Lambert Co.,

(9th Cir. 2001). _____________________________________________________________________ UNITED STATES DISTRICT COURT CENTRAL DISTRICT OF CALIFORNIA

CIVIL MINUTES – GENERAL

Case No.: 8:23-cv-01838-FWS-JDE Date: October 31, 2023 Title: ICON Clinical Research LLC v. Atella Clinical Research LLC et al. The Complaint in this case names three limited liability companies—Plaintiff Icon Clinical Research LLC, Defendant Atella Clinical Research LLC, and Defendant Trio Clinical Trials LLC—as parties (see Dkt. 1 ¶¶ 4-6). The Complaint does not adequately allege the citizenships of these entities’ members as required to plead complete diversity of the parties. See Johnson,

.

The Complaint therefore inadequately establishes this court’s subject matter jurisdiction over the matter. See Kokkonen v. Guardian Life Ins. Co. of Am.,

(1994) (“It is to be presumed that a cause lies outside this limited jurisdiction, and the burden of establishing the contrary rests upon the party asserting jurisdiction.”) (citations omitted); see also Kanter,

(“Absent unusual circumstances, a party seeking to invoke diversity jurisdiction should be able to allege affirmatively the actual citizenship of the relevant parties.”) (citations omitted). Accordingly, the court ORDERS Defendants to show cause in writing no later than November 8, 2023, why this action should not be dismissed for lack of subject matter jurisdiction. Failure to respond by the above date will result in the court dismissing this action without prejudice as to an action filed in state court. See Fed. R. Civ. P. 12(h)(3) (“If the court determines at any time that it lacks subject-matter jurisdiction, the court must dismiss the action.”).

IT IS SO ORDERED.
