LEON D. BLACK,

Petitioner,

RICHARD EMERSON,

Respondent.

ORDER DISMISSING PETITION FOR IMPROPER VENUE

This matter is before the Court on Petitioner Leon D. Black’s Petition to Compel Compliance with Arbitral Subpoena (“Petition”). (ECF No. 1.) On June 16, 2025, the Court issued an Order to Show Cause why it should not dismiss the Petition for lack of subject-matter jurisdiction and/or improper venue (“Show Cause Order”). (ECF No. 26.) Black filed a response to the Show Cause Order (ECF No. 28), to which Respondent Richard Emerson filed a reply (ECF No. 29). For the reasons stated below, the Petition is dismissed without prejudice. I. BACKGROUND1 This subpoena enforcement action arises from arbitral proceedings currently pending before JAMS in New York County, New York, in which Black is plaintiff. (ECF

1 This Background is derived from the Petition and the parties’ substantive briefing related thereto, as well as from the parties’ briefs on the Show Cause Order. (ECF Nos. 1, 11, 15, 28, 29.) All citations to docketed materials are to the page number in the CM/ECF header, which sometimes differs from a document’s internal pagination. No. 1 at ¶ 2.) See Leon Black v. Joshua Harris, JAMS Ref. No. 5425000715. In 2021, Black resigned from his position as the Chief Executive Officer (“CEO”) of Apollo Global Management (“Apollo”), a private equity firm that Black co-founded alongside Joshua Harris. (ECF No. 1 at ¶ 11; ECF No. 11 at 5.) In the arbitration, Black alleges that

Harris disseminated disparaging information in a campaign to oust him as CEO. (Id. at ¶ 11.) According to Black, certain of these disparaging conversations took place between Harris and Emerson, the latter of whom was appointed to Apollo’s board on the same day that Black resigned. (Id. at ¶ 12; ECF No. 11 at 6.) Black successfully petitioned the arbitral panel to issue a third-party subpoena to Emerson, among others, pursuant to the panel’s authority under the Federal Arbitration Act (“FAA”), 9 U.S.C. § 7 (“Section 7”). (ECF No. 1 at ¶¶ 3, 13–16.) As shown in the subpoena, two of the arbitrators’ signature blocks list a business address at JAMS’s offices in New York, and the third lists a business address at JAMS’s offices in Philadelphia. (ECF No. 1-1 at 4.)

Black addressed the subpoena to Emerson’s residence in Boulder, Colorado, although it commanded Emerson to produce documents at the offices of Black’s counsel at Kellogg, Hansen, Todd, Figel & Frederick, P.L.L.C. in Washington, D.C. (ECF No. 1-1 at 2; ECF No. 1 at ¶ 8.) The subpoena further instructed that Alternatively, you may elect to bring the materials identified in Schedule A with you to a hearing before one or more of the undersigned arbitrators to be held on March 13, 2025, at a time and location to be determined by the Arbitration Panel. . . . If you refuse or neglect to obey this SUBPOENA, the United States District Court for the District of Colorado or a court of the State of Colorado of competent jurisdiction, upon petition, may compel your attendance, or punish you for contempt in the same manner provided by law in the courts of the United States. (ECF No. 1-1 at 2.) It appears undisputed that one of the arbitrators had intended to convene a hearing in Denver, Colorado to collect evidence from Emerson. (ECF No. 1 at ¶ 28; ECF No. 11 at 8.) However, after Emerson’s counsel accepted service of the subpoena on his behalf in February 2025, Emerson agreed to produce documents electronically and forgo an in-person hearing. (ECF No. 1 at ¶ 18; ECF No. 11-2.) Emerson’s initial written responses and objections to the subpoena are not in the record, but Black represents that Emerson initially objected to all four document requests propounded by Black, which largely sought documents and communications between Emerson and Harris or otherwise about Black. (ECF No. 1 at ¶¶ 4, 19; ECF No. 11-3; ECF No. 1-1 at 11–12.) After at least one meet and confer and additional written back-and-forth, Emerson produced 28 pages of e-mails on March 13, 2025. (ECF No. 1 at ¶ 24; ECF Nos. 11-3, 11-4.) Black filed the Petition on March 31, 2025,

asserting that “Emerson has given . . . no indication that he intends to produce any additional documents beyond his deficient production on March 13, 2025” and asking the Court to “order Emerson to comply with the Subpoena in full and without withholding any responsive documents at the direction of Harris’s counsel.” (ECF No. 1 at ¶¶ 6, 24.) Since the Petition was filed, the Court understands that Emerson has given deposition testimony at a hearing presided over by the panel on April 11, 2025 in New York. (ECF No. 11-3 (agreeing to testify in New York rather than Denver).) Shortly before the hearing, on April 8, 2025, Emerson produced an additional 86 pages of documents. (ECF No. 11-7.) And after the hearing, on May 6, 2025 Emerson produced a further 18 pages of documents, consisting of text messages. (ECF No. 16-1.) Notwithstanding these additional productions, Black appears to still assert that Emerson has not fully complied with the subpoena. (See ECF No. 15 (May 7 reply); ECF No. 28 (June 23 response to Show Cause Order).) The Court also takes note that, at least as of the parties’ initial substantive briefing on the Petition, the final liability

hearings were to begin on July 28, 2025 under the then-current Case Management and Scheduling Order for the arbitration. (ECF No. 11-5 at ¶ 45.) As Black has not sought to dismiss the Petition or otherwise advised that this discovery dispute has been rendered moot, the Court will presume he was successful in his request to continue the liability hearings and that this discovery dispute remains active. (ECF No. 11-8.) II. ANALYSIS Per its Show Cause Order, the Court must now resolve whether it has subject- matter jurisdiction over the Petition and/or whether the Petition is properly brought in this venue. Ultimately, it concludes that, even if diversity jurisdiction exists, Black has filed the Petition in the wrong venue.

As to subject-matter jurisdiction, the Court reiterates that the FAA does not separately confer federal question jurisdiction, and an independent basis for its subject matter jurisdiction must exist. See Hall Street Assocs., L.L.C. v. Mattel, Inc., 552 U.S. 576, 581–82 (2008) (“As for jurisdiction over controversies touching arbitration, the Act does nothing, being ‘something of an anomaly in the field of federal-court jurisdiction’ in bestowing no federal jurisdiction but rather requiring an independent jurisdictional basis.” (quoting Moses H. Cone Mem’l Hosp. v. Mercury Constr. Corp., 460 U.S. 1, 26 n.32 (1983)); Comanche Indian Tribe v. 49, L.L.C., 391 F.3d 1129, 1131 n.4 (10th Cir. 2004) (“The FAA alone cannot confer subject matter jurisdiction on the federal courts without an independent jurisdictional basis.”). Here, Black alleges that the Court has diversity jurisdiction under 28 U.S.C. § 1332 because the parties are citizens of different states (New York and Colorado) and the amount in controversy exceeds $75,000.
