Opinion

UNITED STATES DISTRICT COURT EASTERN DISTRICT OF NEW YORK ------------------------------------x

ISAAC MAZOR,

Plaintiff, MEMORANDUM & ORDER 25-CV-1020 (EK)(JAM) -against-

SION SHALAM,

Defendant.

------------------------------------x ERIC KOMITEE, United States District Judge: Isaac Mazor alleges that his former business partner, Sion Shalam, defrauded him of $90,000, a fifty-percent ownership stake in an LLC, and an interest in property located in Linden, New Jersey. Shalam then allegedly convinced Mazor to resolve their dispute via a rabbinical arbitration process, which Mazor now contends was illegitimate. Mazor brings claims against Shalam in diversity for breach of fiduciary duty, fraud, unjust enrichment, and specific performance, and asks the Court to set aside the arbitration award. Shalam moves to dismiss the complaint for lack of personal jurisdiction or, in the alternative, on forum non conveniens grounds. For the reasons set forth below, Shalam’s motion is granted: Counts One through Four of the complaint are dismissed for lack of personal jurisdiction, and Count Five is dismissed for forum non conveniens. Background The following facts are drawn from the complaint, as well as the affidavits and other exhibits attached to the parties’ motion papers. See Cooke v. United States, 918 F.3d

77, 80 (2d Cir. 2019) (“To resolve jurisdictional issues, [courts] may consider affidavits and other materials beyond the pleadings . . . .”).1 “The allegations in the complaint [are] taken as true to the extent they are uncontroverted by the defendant’s affidavit[].” MacDermid, Inc. v. Deiter, 702 F.3d 725, 727 (2d Cir. 2012). When a fact is disputed, the Court so notes but relies on Mazor’s version of events. See CutCo Indus., Inc. v. Naughton, 806 F.2d 361, 365 (2d Cir. 1986).2 Mazor and Shalam developed a business relationship through Mazor’s son-in-law, Isaac Massre. Compl. ¶¶ 3, 22, ECF No. 1. According to Mazor, in or around 2021, the three men agreed to form “19 E. Elizabeth Ave Realty, LLC” (“19E”). Id.

¶ 4; Mazor Aff. ¶ 4, ECF No. 12-4. Although 19E was a New Jersey LLC, see Mazor Aff. ¶ 4, Mazor asserts that Shalam “on multiple occasions travelled to New York and he and I would

1 Unless otherwise noted, when quoting judicial decisions this order accepts all alterations and omits all citations, footnotes, and internal quotation marks. 2 In Cutco, the Second Circuit observed: “Although . . . the plaintiff has the ultimate burden of establishing jurisdiction over defendant by a preponderance of the evidence, until an evidentiary hearing is held, it need make only a prima facie showing by its pleadings and affidavits that jurisdiction exists. Those documents are construed in the light most favorable to plaintiff and all doubts are resolved in its favor.” 806 F.2d at 365. frequently speak over the telephone while I was in New York.” Id. ¶ 5.3 At the conclusion of those negotiations, Mazor believed he had a fifty-percent interest in 19E, while Shalam

and Massre each had twenty-five percent stakes. Compl. ¶ 4. In April 2021, the LLC purchased 19 East Elizabeth Avenue in Linden, New Jersey for $1.3 million, on Shalam’s recommendation. Id. ¶ 7. Shalam asked Mazor to contribute $90,000 more than himself and Massre, indicating that Mazor would be reimbursed after they closed on the property. Id. ¶ 8.4 Instead, Shalam used the $90,000 to secure a $900,000 loan in 19E’s name and used part of the loan to repay Mazor. Id. ¶¶ 11, 13. He then insisted Mazor be responsible for his portion of the loan. Id. ¶ 12. Meanwhile, Mazor discovered that Shalam had left him off the LLC’s operating agreement, ostensibly because Mazor had previously filed for Chapter 11 bankruptcy. Id. ¶ 10. When

Mazor pressed Shalam to allow him to sign the operating agreement, Shalam had Mazor’s wife sign instead. Id. ¶¶ 14, 16. Shalam also retaliated against Mazor by filing a lawsuit to evict the factory that Mazor was then operating at 19 East Elizabeth Avenue. Id. ¶ 15. Mazor alleges that the parties met

3 Shalam disclaims any memory of meeting with Mazor in New York. See Shalam Aff. ¶¶ 9-11, ECF No. 11-1. 4 Shalam claims that Mazor “did not provide any funding for the formation of 19E or the purchase of the Property,” and that it was, instead, Mazor’s wife Iris who did so. Shalam Aff. ¶¶ 6-7. to discuss these matters in Brooklyn in September 2021. See Mazor Aff. ¶ 10; see also Meeting Notes, ECF No. 12-5. Ultimately, Shalam asked Mazor to arbitrate their dispute, also in New York. Id. ¶ 17; Mazor Aff. ¶ 6. Mazor

says he believed the arbitration would be before a certified arbitrator who followed the American Arbitration Association Rules. Compl. ¶¶ 17, 20. Instead, it was conducted before Rabbi Eliezer Savitsky. Pl.’s Ex. B, ECF No. 12-2. Shalam and Mazor have filed two different versions of the Arbitration Agreement, only one of which — Mazor’s — has Rabbi Savitsky’s name filled in. Compare Pl.’s Ex. B, with Def.’s Ex. A, ECF No. 13-1. Both versions, however, include a provision consenting to the personal jurisdiction of the courts of the State of New York “for any action or proceeding to confirm or enforce a decree of the arbitrator.” See, e.g., Pl.’s Ex. B.

Mazor indicates in his briefing that Rabbi Savitsky allowed Shalam to proceed with the eviction. Opp’n Br. 5, ECF No. 12-6.5 Otherwise, he says nothing of the arbitration award, except that it was “devoid of any proper explanation for why the ruling was made.” Compl. ¶ 19.

Personal Jurisdiction “[T]o survive a motion to dismiss for lack of personal jurisdiction, a plaintiff must make a prima facie showing that jurisdiction exists.” Penguin Grp. (USA) Inc. v. Am. Buddha,

609 F.3d 30, 34-35 (2d Cir. 2010). “Prior to discovery, . . . plaintiff’s prima facie showing may be established solely by allegations.” Dorchester Fin. Sec., Inc. v. Banco BRJ, S.A., 722 F.3d 81, 84–85 (2d Cir. 2013). And if plaintiff fails to make this showing, the court “does not err in denying jurisdictional discovery.” Chirag v. MT Marida Marguerite Schiffahrts, 604 F. App’x 16, 18–19 (2d Cir. 2015). “We construe the pleadings and affidavits in the light most favorable to [Mazor], resolving all doubts in his favor.” DiStefano v. Carozzi N. Am., 286 F.3d 81, 84 (2d Cir.

2001). But he “may not rely on conclusory statements and must offer actual specificity in order to establish personal jurisdiction.” Shorts v. Cedars Bus. Servs., LLC, 767 F. Supp. 3d 96, 105 (S.D.N.Y. 2025). And, notably, he “must establish the court’s [personal] jurisdiction with respect to each claim asserted.” Sunward Elecs., Inc. v. McDonald, 362 F.3d 17, 24 (2d Cir. 2004). In assessing whether the Court has personal jurisdiction over Mazor’s claims, we first ask whether Shalam consented to jurisdiction in New York. See D.H. Blair & Co. v. Gottdiener, 462 F.3d 95, 103 (2d Cir. 2006) (“Parties can consent to personal jurisdiction through forum-selection clauses

in contractual agreements.”). Absent Shalam’s consent, we then “apply the personal jurisdiction rules of the forum state.” Penguin, 609 F.3d at 35.
