WILL, Vice Chancellor The plaintiff in this action seeks to permanently enjoin an arbitration launched

by his former employer. He argues that the arbitration clause appears in an

improperly amended agreement he never agreed to. In his view, the parties’ dispute

is governed by a prior version of the agreement, which lacks an arbitration clause

and mandates litigation in Delaware.

The evidence presented at an expedited trial shows otherwise. The plaintiff

manifested his assent to the amended agreement when he signed an equity award

that incorporated its terms. He then accepted the amended agreement’s economic

benefits for nearly a year before resigning. Having done so, he is bound by the

agreement, including its arbitration clause. Judgment is for the defendants; the

request for an injunction is denied.

I. BACKGROUND

The following facts were proven by a preponderance of the evidence at a trial

on a paper record.1

1 Trial was presented on an expedited basis and on a paper record. Dkt. 37. The trial transcript is cited as “Trial Tr.” Dkt. 39. 1 A. Lafferty and Corient

Plaintiff John Merrill Lafferty, Jr. is a wealth manager and investment adviser.

In 2004, he joined Segall Bryant & Hamill, LLC, a Chicago-based investment firm,

as a portfolio manager.2 He was later promoted to senior portfolio manager.3

In April 2021, Segall Bryant & Hamill was acquired by an affiliate of Corient

Partners LLC and Corient Services LLC (together, “Corient”), a global wealth and

asset management firm.4 Lafferty received significant proceeds in connection with

the transaction.5

In mid-2023, Lafferty was invited to become a Class B member of Corient

Partners.6 As a result, the structure of his compensation would change from a

fee-based model to a base salary plus quarterly distributions.7

On August 15, 2023, Lafferty executed a Joinder Agreement to the Fourth

Amended & Restated Limited Liability Company Agreement of Corient Partners

2 Verified Pet. to Enjoin Arbitration (Dkt. 1) (“Pet.”) ¶ 11. 3 Unsworn Transmittal Decl. of Gates H. Young in Supp. of Resp’ts’ Answering Br. in Opp’n to Mots. for Expedited Proceedings and for TRO (Dkt. 3) (“Young Decl.”) Ex. 6 (Decl. of Kurt MacAlpine in Supp. of Corient P’rs’ Emergency Mot. for TRO and Prelim. Inj.) (“MacAlpine Decl.”) ¶ 25. 4 MacAlpine Decl. ¶¶ 15-16. 5 Id. 6 Id. ¶ 26. 7 Id. at Ex. 6; Reply Br. in Supp. of Pet’r’s Mot. for Expedited Proceedings and for TRO (Dkt. 16) Ex. A (Decl. of Resp. John Merrill Lafferty, Jr.) (“Lafferty Decl.”) ¶¶ 20-22. 2 LLC (the “Fourth LLC Agreement”).8 In doing so, he agreed to be bound by the

Fourth LLC Agreement “as the same may be amended from time to time.”9

The Fourth LLC Agreement contained a Delaware forum selection clause.

Under Section 13.19 of the Fourth LLC Agreement, Lafferty submitted to the

“exclusive jurisdiction of any state or U.S. federal court sitting in [Delaware] . . .

with respect to any claim or cause of action” that might “aris[e] under or relat[e] to

th[e] Agreement.”10

B. The Fifth LLC Agreement

Under Section 10.01 of the Fourth LLC Agreement, the “CI Member” had the

authority to unilaterally modify or amend the agreement.11 That right was subject to

a limitation. The agreement could not be amended “in any manner that would

materially, adversely, and disproportionately affect any Member, or class of

Members, without the consent of such Member, or a Majority in Interest of such

class[.]”12

8 See Pet. Ex. A (“Fourth LLC Agreement”); see also Pet. Ex. B. (“Joinder Agreement”). 9 MacAlpine Decl. Ex. 7 § 2. 10 Fourth LLC Agreement § 13.19. 11 Id. § 10.01 (explaining that the Fourth LLC Agreement “may be modified, amended, or waived from time to time as determined by the CI Member”); id. at Ex. A, Definitions (defining “CI Member” initially as “CIPW Topco” or its “Permitted Transferee”). A “Permitted Transferee” included “with respect to the CI Member, (i) an Affiliate thereof and (ii) the direct or indirect equityholders, members, partners, or employees of the CI Member or Affiliate.” Id. 12 Id. § 10.01. 3 Through a series of corporate transactions in 2023, Corient Management LLC

became the CI Member of Corient Partners.13 On February 7, 2024, Corient

Management exercised its authority under Section 10.01 to enact the Fifth Amended

& Restated Limited Liability Company Agreement (the “Fifth LLC Agreement”).14

The Fifth LLC Agreement fundamentally changed the company’s dispute

resolution framework. It eliminated Section 13.19 of the Fourth LLC Agreement,

which had provided for exclusive jurisdiction in Delaware courts, and replaced it

with an arbitration provision.15 The revised provision—now Section 14.02—read:

Any action, suit, or other legal proceeding arising out of or relating to this Agreement (including the enforcement of any provision of this Agreement) or the legal relationship of the parties hereto (whether at law or in equity, whether in contract or in tort, or otherwise) shall be submitted to final and binding arbitration. Such arbitration shall be conducted before a neutral arbitrator in accordance with the JAMS Comprehensive Arbitration Rules & Procedures (including any subsequent modifications or amendments thereto, the “JAMS Rules”), as the exclusive remedy for such controversy, claim or dispute, and shall be located in New York, New York or Miami, Florida.16

13 Unsworn Decl. of Scott Akins in Supp. of Resp’ts’ Trial Br. (Dkt. 31) (“Akins Decl.”) ¶¶ 3, 5-6. 14 See Young Decl. Ex. 2 (Fifth Amended & Restated Limited Liability Company Agreement of Corient Partners LLC) (“Fifth LLC Agreement”); Akins Decl. ¶ 6. 15 Compare Fourth LLC Agreement § 13.19, with Fifth LLC Agreement § 14.02. 16 Fifth LLC Agreement § 14.02(a). 4 Section 14.02 permitted parties to “conduct discovery to the same extent as would

be permitted in a court of law[,]” and “irrevocably” waived their rights to a jury

trial.17

C. Notification of the Amendment

On February 28, 2024, Corient’s Senior Vice President and General Counsel,

Scott Akins, emailed Corient Partners’ members.18 He explained that changes had

been made to the Fourth LLC Agreement to “better reflect the way the partnership

operates in practice.”19 He assured the members that “none of the changes to the

agreement materially, adversely, and disproportionately affect any partner or the

individual partners.”20 He also told them to “be on the lookout for a system

generated [] email notification[,]” which would grant them access to a virtual portal

(Carta) containing the Fifth LLC Agreement.21
