UNITED STATES DISTRICT COURT SOUTHERN DISTRICT OF NEW YORK

Mark J. Kwoka et al.,

Plaintiffs–Counter Defendants, 24-cv-2246 (AS) -against- Diane D’Angelo, OPINION AND ORDER Defendant–Counter Plaintiff.

ARUN SUBRAMANIAN, United States District Judge: This case involves a dispute over the ownership of a wedding-dress company. The parties cross-moved for summary judgment on plaintiffs’ claims, and defendant moved for sanctions. For the reasons below, plaintiffs’ motion for summary judgment is DENIED and defendant’s motion for summary judgment is GRANTED. Defendant’s motion for sanctions is DENIED. BACKGROUND Mark Kwoka and Diane D’Angelo met at a New York trade show for wedding dresses (the parties dispute whether this was in 2018 or 2019). Dkt. 130 ¶ 2; Dkt. 133-2 ¶ 1. D’Angelo at the time marketed her dresses under the brand name “Lasting Memories.” Dkt. 133-2 ¶ 3. After they met, the two worked together to sell dresses under the name “Esme Designs.” Dkt. 130 ¶¶ 2–4; Dkt. 133-2 ¶ 3. D’Angelo designed the products, while Kwoka handled production. Dkt. 133-2 ¶ 2. Esme Designs LLC was organized under the laws of the State of Florida by Kwoka in July 2019. Dkt. 130 ¶ 3; Dkt. 133-2 ¶ 5. D’Angelo was listed as the “Manager” of the company. Dkt. 133-2 ¶ 6. In January 2024, Kwoka told D’Angelo he wanted to end their business relationship. Dkt. 130 ¶ 5; Dkt. 133-2 ¶ 17. Kwoka asked D’Angelo to transfer her interest in the business to him and to cease doing any business under the Esme Designs name. Dkt. 133-2 ¶ 17. Two weeks later, Kwoka sent D’Angelo a “Memorandum of Understanding” detailing his buyout proposal. Dkt. 130 ¶ 8; Dkt. 133-2 ¶ 21. Following her receipt of Kwoka’s proposal, D’Angelo consulted legal counsel, who wrote to Kwoka and demanded that he stay away from Esme Designs’ bank account and accounting soft- ware. Dkt. 130 ¶ 10; Dkt. 133-2 ¶ 23. Kwoka claims a 50% interest in Esme Designs; D’Angelo believes she owns the business outright. Dkt. 130 ¶ 4; Dkt. 127 at 5. In March 2024, Kwoka organized Esme Private Label LLC under the laws of the State of New York. Dkt. 138-2 at 6. He subsequently initiated this lawsuit against D’Angelo, listing the new LLC as a co-plaintiff. Dkt. 1. The amended complaint alleges breach of fiduciary duty, equitable estoppel, several contractual claims, and fraud. Dkt. 7. D’Angelo counterclaimed for conversion, tortious interference with business relationships, and for a declaratory judgment on ownership. Dkt. 54. The parties filed cross-motions for summary judgment on plaintiffs’ claims, and D’An- gelo moved for sanctions under Federal Rule of Civil Procedure 11. Dkts. 125, 128, 140. Plaintiffs did not move for summary judgment on any of D’Angelo’s counterclaims. LEGAL STANDARDS “The court shall grant summary judgment if the movant shows that there is no genuine dispute as to any material fact and the movant is entitled to judgment as a matter of law.” Fed. R. Civ. P. 56(a). A dispute is “genuine” if a reasonable jury could find for either side. Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 248 (1986). And a fact is “material” if it could “affect the outcome.” Id. The Court views the record “in the light most favorable to the non-movant.” Williams v. MTA Bus Co., 44 F.4th 115, 126 (2d Cir. 2022) (cleaned up). But if the non-movant will bear the burden of proof on an issue at trial, it must point to some evidence supporting the “essential element[s]” of its position. Celotex Corp. v. Catrett, 477 U.S. 317, 322–23 (1986). DISCUSSION I. The Court looks to Florida’s default rules to determine ownership of Esme Designs LLC The parties in this case agree on very little. They do not agree on whether the Court should decide who owns Esme Designs LLC. They do not agree on how to decide who owns the entity. And they certainly do not agree on who owns Esme Designs LLC. For the following reasons, the Court concludes that ownership is a necessary question in resolving the claims at issue on the cross-motions and determines that Florida LLC law, rather than principles of estoppel, determine ownership. A. The ownership of Esme Designs is a necessary question to resolving the parties’ motions The first question is whether the Court should resolve the ownership of Esme Designs LLC. Plaintiffs argue that the ownership question is relevant to resolving the claims. E.g. Dkt. 139 at 4– 5. D’Angelo disagrees, believing that plaintiffs did not assert a claim for ownership and thus the matter is outside the scope of the pleadings and cannot be resolved on summary judgment. Dkt. 135 at 2–3. The Court agrees with plaintiffs that the ownership of Esme Designs LLC is within the scope of the case and ripe for resolution on summary judgment. Plaintiffs’ claims, which are the subject of the cross-motions, rest on their understanding of the ownership of the entity. For example, plain- tiffs’ claim for breach of fiduciary duty necessarily rests on the assumption that Kwoka has an ownership stake in the company—if he did not, he has no theory as to why D’Angelo would owe him and his LLC a fiduciary duty in the first place. The question of Esme Designs LLC’s owner- ship is within the scope of this case and the pending motions. And it is procedurally proper to address that question now. After the cross motions were filed, neither side suggested that there was any reason—for example under Fed. R. Civ. P. 56(d)–(f)—that the issue could not be resolved on the present record. B. The Court applies Florida law to determine ownership of the entity The next question is how to determine ownership of Esme Designs. Plaintiffs argue that D’An- gelo is estopped from claiming that Kwoka lacks an ownership stake in Esme Designs LLC. Dkt. 129 at 8–9. D’Angelo argues that estoppel does not apply, and the Court should instead apply default principles from Florida or New York law. Dkt. 135 at 4–8. The Court agrees with D’Angelo and applies Florida law. Plaintiffs’ argument borrows elements of different estoppel doctrines, but their argument boils down to this: Esme Designs LLC’s tax returns listed a company, Philmar Trading Corporation, apparently owned by Kwoka, and D’Angelo as 50/50 owners in a partnership, and so D’Angelo should be estopped from claiming that Kwoka isn’t an owner of the company. The Court disagrees. As one of plaintiffs’ cases states, “[w]ithin the Second Circuit, the ‘application of judicial es- toppel is limited to situations where the risk of inconsistent results threatens the integrity of the judicial process.’” Am. Mfrs. Mut. Ins. Co. v. Payton Lane Nursing Home, Inc., 704 F. Supp. 2d 177, 194 (E.D.N.Y. 2010) (quoting Simon v. Safelite Glass Corp., 128 F.3d 68, 72–73 (2d Cir. 1997)). In American Manufacturers, the question was whether a party was taking an inconsistent position on the categorization of some transactions in litigation (to gain an advantage over the adverse private party) compared to how it had represented those transactions to the IRS (to reduce tax liability). Id. at 194–201. In effect, the American Manufacturers court held that a party cannot have its cake and eat it too. No such unfairness exists here.
