UNITED STATES DISTRICT COURT SOUTHERN DISTRICT OF NEW YORK

ANDRE PAUWELS, Plaintiff, v. 19-CV-2313 (RA) OPINION AND ORDER BANK OF NEW YORK MELLON

CORPORATION, THE BANK OF NEW YORK

MELLON, DELOITTE LLP, DELOITTE USA LLP, and DELOITTE TAX LLP, Defendants.

RONNIE ABRAMS, United States District Judge:

Plaintiff Andre Pauwels’s sole surviving claim in this matter is for unjust enrichment against Defendants The Bank of New York Mellon Corporation and The Bank of New York Mellon (together, “BNYM”). See Pauwels v. Deloitte LLP, 83 F.4th 171, 188–89 (2d Cir. 2023). Pauwels is an investment analyst who developed a financial model (the “Pauwels Model”) for BNYM’s tax-equity investments in wind energy projects. Pauwels used this model to advise BNYM about the viability of proposed investments, and to monitor the performance of the investments BNYM chose to pursue. Dkt. 156 (“BNYM Rule 56.1”) ¶ 9. In total, Pauwels created twelve spreadsheets to analyze and track about twenty investments. Id. ¶ 19. In September 2016, Pauwels stopped performing monitoring work for BNYM and was replaced by Deloitte LLP, Deloitte Tax LLP, and Deloitte USA LLP (together, “Deloitte”), id. ¶ 22, although Pauwels continued to help BNYM evaluate new investments. The parties dispute the extent to which Deloitte used the Pauwels Model when customizing its own tool, called iPACS, to monitor BNYM’s investments, though BNYM admits that Deloitte referenced Pauwels’s spreadsheets when it tailored its iPACS tool to these investments. Id. ¶¶ 36–37. Pauwels alleges that Deloitte’s iPACS model was essentially a “copy” of Pauwels’s spreadsheets, Dkt. 169 (“Pauwels Rule 56.1”) ¶ 68, and that BNYM saved money because it avoided paying Deloitte to create a full model from scratch, id. ¶ 67, in addition to otherwise benefitting from the model. Pauwels eventually stopped advising BNYM on new investments, although the parties disagree about how their relationship ended. BNYM claims that the arrangement had concluded

by the end of 2017, when it stopped making new tax-equity investments in wind projects. BNYM Rule 56.1 ¶¶ 41–42. Pauwels claims that BNYM terminated the relationship after he complained about Deloitte’s use of his spreadsheets in its monitoring work. Pauwels Rule 56.1 ¶¶ 70–76. While the parties never entered into a written contract governing Pauwels’s work, BNYM consistently paid Pauwels on an hourly basis. BNYM Rule 56.1 ¶¶ 10, 21. On October 6, 2023, the Second Circuit affirmed this Court’s dismissal of Pauwels’s trade secret claims based on the “oral or implied-in fact” contract between Pauwels and BNYM. Pauwels, 83 F.4th at 182, 187. Consistent with the Second Circuit’s opinion, however, there remains a “bona fide dispute” over whether the oral or implied contract between the parties governed whether BNYM may use the

Pauwels Model spreadsheets for its own purposes. Id. at 188. The essence of Pauwels’s unjust enrichment claim is that BNYM paid Pauwels “strictly for his consulting services,” but that BNYM continued to use Pauwels’s spreadsheets following the termination of the parties’ relationship, and was thus unjustly enriched. Id. Pauwels now demands a jury trial on his unjust enrichment claim or, in the alternative, seeks for the Court to appoint an advisory jury. Dkt. 188. BNYM opposes, urging a bench trial instead. Dkt. 186. For the reasons that follow, the Court agrees with Pauwels that he is entitled to a jury trial on his unjust enrichment claim. BACKGROUND1 Count V of Pauwels’s Second Amended Complaint (“SAC”) alleges that “[b]y taking the Pauwels Model and Pauwels Model Spreadsheets and giving them to Deloitte to use and copy, despite Pauwels’ express admonition against doing so, BNYM enriched themselves by avoiding the time and expense of paying Deloitte to develop their own model for analyzing BNYM’s wind-

energy investments, which would have taken more time and been more expensive than just copying the Pauwels Model.” Dkt. 63 ¶ 109. It further asserts that “[b]ecause Pauwels (a) had his model taken from him against his instructions and wishes, (b) was deceived by BNYM as to their plans to give the Pauwels Model to Deloitte, and (c) was ultimately terminated after BNYM took what they wanted from Pauwels (i.e., his model) surreptitiously, BNYM was enriched at Pauwels’ expense.” Id. ¶ 111. The SAC seeks “damages, including compensatory damages in quantum meruit, and punitive damages, for Defendants’ . . . unjust enrichment.” Id. at 32. Pauwels argues that he is entitled to a jury trial on this unjust enrichment claim; BNYM disagrees. By order dated July 9, 2025, the Court directed the parties to file briefing on the question

of whether Pauwels’s remaining claim should be tried by a jury or by bench trial. Dkt. 180. Pauwels and BNYM submitted letter briefs on this question, Dkt. 186 (“Def’s Br.”), 188 (“Pl’s Br.”), and responses thereto, Dkt. 194 (“Def’s Reply”), 195 (“Pl’s Reply”), as well as supplemental briefing requested by the Court, Dkt. 212 (“Def’s Suppl. Br.”), 213 (“Pl’s Suppl. Br.”), and further responses. Dkt. 216 (“Pl’s Suppl. Reply”); Dkt. 217 (“Def’s Suppl. Reply”). The Court heard oral argument on October 20, 2025 (“Oral Arg. Tr.”), after which Pauwels and BNYM submitted additional letters. Dkt. 225, 226.

1 The Court assumes the parties’ familiarity with the facts and procedural history of this case, and sets forth only those facts necessary for the instant Opinion and Order. In his briefing on these issues, Pauwels initially stated that he is seeking “damages in the amount of the benefit that BNYM received as a result of its decision to take the Pauwels Model without authorization, including, for example, the savings BNYM realized by not having to pay Deloitte to develop a new model from scratch.” Pl’s Br. at 3 n.3. But in the course of further briefing and related pretrial motions, Pauwels has narrowed his damages theory to clarify that he

is no longer seeking “the savings BNYM realized by not having to pay Deloitte to develop a new model from scratch,” and is therefore not seeking “restitution of specific property.” Pl’s Suppl. Br. at 3. Rather, he is now seeking only to recover the intrinsic value of the Pauwels Model at the time he alleges it was wrongfully taken by BNYM. Id.; Oral Arg. Tr. 4:15–5:16, 10:3–8. This narrowing is relevant for two reasons. First, the original remedy that Pauwels appeared to seek—“restitution” of BNYM’s avoided third-party costs from the use of the Pauwels Model2—is barred by the New York Court of Appeals’s decision in E.J. Brooks Co. v. Cambridge Sec. Seals (“Brooks II”), 31 N.Y.3d 441, 455–57 (2018). Brooks II, however, does not bar Pauwels’s revised articulation of his damages theory, which seeks to recover the value of the

Pauwels Model itself. Second, as the Court discusses further below, the civil jury trial right depends in part on whether the remedy sought by a party “is legal or equitable in nature.” Granfinanciera, S.A. v. Nordberg, 492 U.S. 33, 42 (1989).3 A party seeking a legal remedy is more likely to be entitled to try their case to a jury. Restitution of BNYM’s profits from the use of the Pauwels Model constitutes an equitable remedy, while restitution of the value of the Pauwels

2 This type of restitutionary remedy is also called an “accounting for profits,” see, e.g., Pender v. Bank of Am. Corp., 788 F.3d 354, 364 (4th Cir. 2015), which “requires the disgorgement of profits produced by property which in equity and good conscience belonged to the plaintiff.” Id. (quoting 1 D. Dobbs, Law of Remedies § 4.3(5) (2d ed. 1993)). 3 Unless otherwise indicated, case quotations omit all internal citations, quotations, footnotes, omissions, and alterations. Model when it was taken by BNYM constitutes a legal one.
