Opinion

UNITED STATES DISTRICT COURT EASTERN DISTRICT OF NEW YORK ne ne tt to i ae MOHAMED DADDE, Plaintiff, “agaIns NOT FOR PUBLICATION MEMORANDUM & ORDER QUEST DIAGNOSTICS INCORPORATED, and 24-cv-465 (CBA) “JANE DOE”, THE PRESENTLY UNKNOWN PHLEBOTOMIST AND/OR AGENT AND/OR EMPLOYEE OF QUEST DIAGNOSTICS, Defendants. ea ek TA AMON, United States District Judge: Piaintiff Mohamed Dadde filed a negligence suit against two defendants: (1) Quest Diagnostics Incorporated (“Quest”), and (2) a phlebotomist whose identity was then unknown to Dadde and who was thus named as ‘Jane Doe’. (ECF Docket Entry (“D.E.”) # 1 Ex. 1 (“Compl.”).) Quest removed the case to this Court. (D.E. # 1 (“Notice of Removal”).) At some point after removal, Dadde learned that Doe’s true identity was that of Marcia Blackman. (D.E. #28 Ex. 1 Mot.”).) Since both Dadde and Blackman are New York residents, Blackman’s inclusion as a party would defeat diversity jurisdiction. (Id, 6.) Dadde has filed a second suit based on the same conduct in New York state court, this time naming Blackman as a defendant. (Id. 2.) Now, he asks me fo either dismiss this case without prejudice to allow him to pursue his New York state case or substitute Blackman as a named defendant in this case and remand it to state court. For the reasons set out below, I DENY Dadde’s motion to dismiss this case without prejudice, but I GRANT his motion to substitute Blackman as a defendant and remand this case to state court.

BACKGROUND On December 19, 2023, Dadde filed a negligence suit against Quest and a phlebotomist then named as ‘Jane Doe’ in New York Supreme Court, Kings County. (Compl.) Dadde alleged that on June 13, 2023, the unknown phlebotomist failed to properly supervise Dadde after his venipuncture, causing Dadde to “faint, lose consciousness and fall to the ground with great force.” (id. | 24.) Dadde’s complaint alleged no federal cause of action. On January 22, 2024, Quest removed the case to this Court alleging jurisdiction based on diversity of citizenship. (Notice of Removal 17.) Dadde is a New York resident and Quest is a Delaware corporation whose principal place of business is in New Jersey. (Id. ff] 8-9.) Dadde has not disputed that he seeks over $75,000 in damages. On March 25, 2024, as the parties exchanged initial discovery, Quest informed Dadde that the phlebotomist previously known as ‘Jane Doe’ was Marcia Blackman. (D.E. # 17.) Blackman, like Dadde, is a New York resident, (P!. Mot. 6.) On September 16, 2024, Dadde filed a new lawsuit based on the same conduct in New York state court, this time naming Quest and Blackman as defendants. (D.E, #23 Ex. 1.) In the instant motion, Dadde asks that I grant one of two forms of relief. First, Dadde asks that I dismiss this case without prejudice to allow his new state case to proceed. (PI. Mot. 10.) Alternatively, he asks that I “substitutfe] Marcia Blackman for Jane Doe and remand[] the case to state court.” (Id.) Quest opposes both forms of relief. As to dismissal without prejudice, Quest argues that it would be inappropriate for me to dismiss this case so that a “duplicative action” could proceed in state court. (D.E. #25 (“Def. Opp.”) 13.) As to substitution, Quest argues that Dadde has been dilatory in seeking Blackman’s addition to this case, adding Blackman would prejudice Quest,

denying Dadde’s motion poses no risk of causing multiple litigation, and Dadde’s motivations for secking Blackman’s addition are improper. (Id. 9-16.) DISCUSSION I discuss each of Dadde’s requested forms of relief separately. I. Dismissal of This Action Without Prejudice is Unwarranted Once a defendant has served an answer or a motion for summary judgment upon a plaintiff, that plaintiff may not unilaterally voluntarily dismiss his lawsuit without a court order, and a district court should only issue such an order “on terms that the court considers proper.” Fed, R. Civ. P. 41(a). Quest served its answer well before Dadde filed the instant motion, (See D.E. # 8.) Thus, I must consider whether it would be proper to grant the voluntary dismissal Dadde seeks. I find that it is not. As I describe infra § II, the Second Circuit has a well-established four- factor test for determining whether it would be more appropriate to join Blackman and remand this case to state court or to deny joinder. To grant dismissal without prejudice would be to defeat the point of this test. As Quest has observed, granting Dadde’s motion to dismiss this case without prejudice would have the identical effect to granting Dadde’s motion to join Blackman and remand this case. (See Def. Mot. 13-14.) For this reason, I deny Dadde’s motion to dismiss this case without prejudice. Il. Blackman Should Be Joined as a Defendant, so Remand Is Proper When determining whether a civil action is removable based on diversity jurisdiction, “the citizenship of defendants sued under fictitious mames shall be disregarded.” 28 U.S.C. § 1441(b)G1). But a plaintiff may later learn the identity of a fictitious defendant and move to substitute accordingly. When a nondiverse party “has been ‘substituted’ for the ‘John Doe’ defendant, it is also accurate to say that he has been ‘joined’ as a defendant for the purposes of

§ 1447(e), destroying diversity.” Cartagena v. Ryder Truck Rental, Inc., No. 23-CV-4169 (JPO), 2023 WL 8520487, at *2 (S.D.N.Y. Dec. 8, 2023); see, e.g., Newcombe v. Adolf Coors Co., 157 F.3d 686, 690-91 (9th Cir. 1998) (analyzing a substitution of a named defendant for a Doe defendant as a matter of joinder), Thus, the proper question is whether Marcia Blackman should be joined as a defendant under 28 U.S.C. § 1447(e). Joinder may be mandatory, see Fed. R. Civ. P. 19, or permissive, see Fed. R. Civ. P. 20. To determine whether mandatory joinder applies, I must determine whether Blackman is an indispensable party. A defendant is indispensable if “in that person’s absence, the court cannot accord complete relief among existing parties.” Fed. R. Civ. P. 19(a)(1)(A). Dadde argues that Blackman is an indispensable party because Blackman was purportedly “the actual tortfeasor” and “the only person with actual... knowledge of what transpired.” (PI. Mot. 5-6.) Quest has offered to stipulate that it is “vicariously liable for Ms. Blackman’s actions in the scope of her employment,” that it is able to “cover Ms, Blackman and itself for any damages[,]” and that it “would not disclaim or deny insurance coverage for Ms. Blackman with respect to the blood draw at issue.” (Def. Mot. 13.) These facts demonstrate that Blackman is not an indispensable party; to whatever extent Dadde could obtain relief from Blackman, Quest appears willing to supply that relief itself. See Reit v. Post Properties, Inc., No. 09 Civ, 5455 (RMB), 2010 WL 743533, at *2 (S.D.N.Y, Feb. 24, 2010) (“Rosario is not a necessary party because, among other reasons, Plaintiff may recover completely against the Defendants on a theory of respondeat superior without the absent party’s presence in any judgment Plaintiff may win.”) (cleaned up). Thus, mandatory joinder does not apply in this case. On the other hand, Blackman is clearly an appropriate defendant for permissive joinder under Fed, R. Civ. P. 20(a)(2), since Dadde seeks to assert a “right to relief’ from Blackman based

on the same set of facts Dadde has pled against Quest.
