SUMMARY **
Arbitration
The panel affirmed the district court’s order granting
summary judgment in favor of Oppenheimer & Co., Inc.,
which sought a declaration that the Defendants, the alleged
victims of a Ponzi scheme, were not its customers and
therefore not entitled to arbitration; and entering a permanent
injunction prohibiting Defendants from arbitrating their
claims.
In November 2021, Defendants commenced an
arbitration proceeding against Oppenheimer in the dispute
resolution arbitral forum of the Financial Industry
Regulatory Authority (FINRA). Before a final evidentiary
hearing was scheduled to begin before a panel of arbitrators,
Oppenheimer filed the present action against Defendants.
Although Defendants conceded that they had no direct
relationship with Oppenheimer, a FINRA member, they
alleged that they were customers of Oppenheimer for
purposes of FINRA Rule 12200 because they transacted with
Oppenheimer employee John Woods, who was one of
Oppenheimer’s “associated persons” within the meaning of
the FINRA Code.
The panel held that a “customer” under FINRA Rule
12200 includes any non-broker and non-dealer who
purchases commodities or services from a FINRA member
or its associated person. The panel found that Defendants

OPPENHEIMER & CO. INC. V. MITCHELL 3
could be entitled to arbitrate their claims against
Oppenheimer if they could demonstrate that they transacted
with Woods. Nevertheless, the panel agreed with the district
court that Defendants did not transact with Woods because
they purchased their investments from Woods’s associate,
Michael Mooney, and not from Woods himself. The panel
further rejected Defendants’ claim that their investments,
through Mooney, and into an entity formed and controlled
by Woods, may be attributed to Woods under an “alter ego”
theory of liability.
The panel held that the district court did not abuse its
discretion by entering a permanent injunction. The panel
rejected Defendants’ contentions that the district court erred
by introducing unsupported requirements for the legal
definition of a “customer” and by making factual findings
that were unsupported by the record.

OPINION
M. SMITH, Circuit Judge:
Defendants, the alleged victims of a Ponzi scheme
perpetrated by John Woods, seek to bring supervisory
liability claims against Woods’s employer, Plaintiff
Oppenheimer & Co. Inc. Because FINRA Rule 12200
obligates FINRA members to arbitrate the claims of
customers upon request, Defendants brought their claims
against Oppenheimer, a FINRA member, in one of FINRA’s
arbitral forums. Oppenheimer responded by commencing
these proceedings in federal court, seeking a declaration that
Defendants were not its customers and therefore not entitled
to arbitration. The district court agreed. After a limited
period of discovery, it granted summary judgment in favor
of Oppenheimer and entered a permanent injunction
prohibiting Defendants from arbitrating their claims.
Defendants timely appeal that outcome. Although they
concede that they have no direct relationship with
Oppenheimer, they maintain—as they did in the district
court—that they are customers of Oppenheimer for purposes
of FINRA Rule 12200 because they transacted with Woods,
who is one of Oppenheimer’s “associated persons” within
the meaning of the FINRA Code. Defendants accordingly
OPPENHEIMER & CO. INC. V. MITCHELL 5
ask that we vacate the district court’s injunction and
authorize them to proceed in arbitrating their claims.
Defendants further argue that, even if they are not customers
of Oppenheimer, the district court abused its discretion by
entering a permanent injunction and committed reversible
legal errors in its analysis.
We disagree. We conclude, as did the district court, that
individuals who transact with “associated persons” of
FINRA members are “customers” of those FINRA members
for purposes of FINRA Rule 12200. Therefore, we find that
Defendants could be entitled to arbitrate their claims against
Oppenheimer if they could demonstrate that they transacted
with Woods. Nevertheless, we agree with the district court
that Defendants did not transact with Woods because they
purchased their investments from Woods’s associate,
Michael Mooney, and not from Woods himself. We further
reject Defendants’ claim that their investments, through
Mooney, and into an entity formed and controlled by Woods,
may be attributed to Woods under an “alter ego” theory of
liability. Because we discern no other errors in the district
court’s analysis, we affirm its order in full.
FACTUAL BACKGROUND
Plaintiff-Appellee Oppenheimer & Co. Inc.
(Oppenheimer) is a securities firm headquartered in New
York, with approximately 90 branch offices across the
United States. Oppenheimer is a member of the Financial
Industry Regulatory Authority (FINRA) and is registered
with the Securities and Exchange Commission (SEC) as both
a broker-dealer and an investment advisor. Through its
registered investment adviser representatives, including
John Woods (Woods), an employee in Oppenheimer’s
6 OPPENHEIMER & CO. INC. V. MITCHELL
Atlanta, Georgia branch, Oppenheimer offers a variety of
investment products for sale.
Defendants-Appellants Steven and Dori Mitchell (the
Mitchells) and Jerome and Lori Hopper (the Hoppers) are
retired pilots and their spouses who invested in an alleged
Ponzi scheme perpetrated by Woods. According to
Defendants, while Woods was employed by Oppenheimer
between 2003 and 2016, he controlled two companies—
Horizon Private Equity, III, LLC (Horizon), a private equity
fund, and Livingston Group Asset Management Company,
Inc. d/b/a Southport Capital (Southport), an investment
advisor—that collaborated to prey upon elderly victims.
Specifically, under the direction of Woods, Southport
allegedly entreated individuals to invest in Horizon based
upon material misrepresentations that their investments were
safe and secure, would pay a fixed rate of return, and could
be returned without penalty subject to limited waiting
periods. According to Defendants, these guarantees—and
their investments—proved to be worthless, while Horizon
was a shell entity that made no returns and instead operated
only by paying out funds derived from new investor capital.
Working with Michael Mooney (Mooney), one of
Southport’s registered representatives, the Hoppers invested
approximately $600,000 of their retirement savings into
Horizon beginning in May 2016. The Mitchells, also
working with Mooney, invested over $1,600,000 beginning
in July 2016. Defendants’ investments, and their
interactions with Southport, were facilitated primarily by
Mooney, who sold Defendants their securities, served as
their ongoing investment adviser, and earned commissions
on their business. In investing in Horizon, Defendants had
no contact or relationship with any representative of
Oppenheimer. Apart from a single phone conversation
OPPENHEIMER & CO. INC. V. MITCHELL 7
between the Mitchells and Woods in 2016, Defendants also
had no direct contact or relationship with Woods.
PROCEDURAL BACKGROUND
In November 2021, Defendants, along with one other
claimant, commenced an arbitration proceeding against
Oppenheimer in FINRA’s dispute resolution arbitral forum.
The proceeding, which was styled as Mitchell v.
Oppenheimer & Co. Inc., FINRA No. 21-02818 (the FINRA
Arbitration), arose from Defendants’ claims that Woods was
perpetrating a Ponzi scheme that preyed upon elderly
victims. Through their arbitration statement of claim,
Defendants alleged that Woods, Southport, Horizon, and
Mooney had collectively induced them to invest millions in
Horizon based upon material misrepresentations that
investing was profitable and low-risk. Defendants further
alleged that Oppenheimer, as Woods’s employer, failed to
carry out its legal duty to supervise Woods and his business
activities.
The FINRA Arbitration proceeded through discovery,
and a panel of three FINRA arbitrators was selected to
oversee the arbitration in accordance with the FINRA Code.
A final evidentiary hearing was scheduled to begin before
the panel of arbitrators in March 2023. Before that hearing
occurred, Oppenheimer filed the present action against
Defendants in January 2023. Through the action, to which
Woods is not a party, Oppenheimer sought a declaratory
judgment that it was not required to arbitrate with
Defendants because they were not its customers for purposes
of FINRA Rule 12200. Oppenheimer further sought a
permanent injunction prohibiting Defendants from
arbitrating their claims.
8 OPPENHEIMER & CO. INC. V. MITCHELL
In March 2023, the district court granted Oppenheimer’s
motion for a preliminary injunction. Limited discovery then
proceeded, followed by briefing on the parties’ cross-
motions for summary judgment. During this time,
Defendants voluntarily moved to dismiss without prejudice
their claims in the FINRA Arbitration. The arbitration panel
granted Defendants’ motion and held that if Defendants
prevailed in federal court, they could “separately or jointly
refile their claims in arbitration proceeding(s) at a later date.”
In April 2024, the district court granted Oppenheimer’s
motion for summary judgment and denied Defendants’
cross-motion for summary judgment. It held that
Defendants were not customers of Woods or Oppenheimer,
and therefore not entitled to arbitrate their claims under
FINRA Rule 12200, because they did not purchase their
interests in Horizon through or from Woods or
Oppenheimer. It further held that Oppenheimer had satisfied
the requirements for a permanent injunction because
Oppenheimer would be irreparably harmed by proceeding to
arbitration, the equities favored Oppenheimer’s cause, and
there was no public interest in compelling Oppenheimer to
arbitrate against its wishes. The district court then entered a
permanent injunction prohibiting Defendants from
arbitrating their claims. Defendants timely appealed.
STATUTORY BACKGROUND
FINRA, formerly the National Association of Securities
Dealers, Inc. (NASD), is a not-for-profit corporation
registered with the SEC as a national securities association
under the Maloney Act. 15 U.S.C. § 78o–3. “FINRA is a
self-regulatory organization that has ‘the authority to
exercise comprehensive oversight over “all securities firms
that do business with the public.”’” Goldman, Sachs & Co.
OPPENHEIMER & CO. INC. V. MITCHELL 9
v. City of Reno, 747 F.3d 733, 737 (9th Cir. 2014) (quoting
UBS Fin. Servs., Inc. v. W. Va. Univ. Hosps., Inc., 660 F.3d
643, 648 (2d Cir. 2011)). To ensure this oversight, all
securities firms seeking to conduct transactions with the
investing public in the United States are required to register
as FINRA members. 15 U.S.C. § 78o(b)(8); 17 C.F.R.
§ 240.15b9-1. Members agree to abide by FINRA’s set of
rules and regulations, known as the FINRA Code. FINRA
Bylaws, art. IV, § 1(a).
One of the rules by which FINRA members agree to
abide is FINRA Rule 12200, which provides that “[p]arties
must arbitrate a dispute under the [FINRA] Code” if three
conditions are satisfied. FINRA Rule 12200. First,
arbitration must be “either (1) [r]equired by a written
agreement, or (2) [r]equested by the customer.” Id. Second,
the dispute must be “between a customer and a member or
associated person of a member.” Id. Third, and finally, the
dispute must “arise[] in connection with the business
activities of the member or the associated person.” Id. If
these three conditions are present, a de facto “agreement” is
created that permits customers to submit claims to FINRA’s
arbitral forums. Reno, 747 F.3d at 739 n.1. Pursuant to the
Federal Arbitration Act (FAA), such agreements to arbitrate
are “valid, irrevocable, and enforceable, save upon such
grounds as exist at law or in equity for the revocation of any
contract.” 9 U.S.C. § 2; see also Reno, 747 F.3d at 739. 1

The NASDA Code of Arbitration, which was the predecessor to the
FINRA Code, included NASDA Rule 10301, a rule regarding arbitration
that is analogous to FINRA Rule 12200. FINRA has clarified that,
despite surface-level amendments to the language of the two rules, there
is no substantive difference between them. See Comparison Chart of
10 OPPENHEIMER & CO. INC. V. MITCHELL
FINRA’s arbitral forums offer a relatively efficient and
low-cost pathway for conflict resolution. According to the
amicus brief of the Securities Industry and Financial Markets
Association (SIFMA), FINRA arbitration “incorporates
substantive and procedural protections comparable to court-
based litigation, and thereby ensures fair case outcomes for
retail customers.” Kevin Carroll, Securities Arbitration
Works Effectively and Benefits Investors, Sec. Indus. & Fin.
Mkts. Ass’n (Oct. 5, 2021),
https://www.sifma.org/resources/news/blog/securities-
arbitration-system-works-effectively-and-benefits-investors
[hereinafter SIFMA Arbitration Article]. Further, FINRA
arbitration provides for “faster resolution of disputes” than
court-based litigation and “reduces legal costs.” Kevin M.
Carroll et al., White Paper on Arbitration in the Securities
Industry 50 (2007), https://www.sifma.org/wp-
content/uploads/2017/05/sifma-sifmacl-white-paper-on-
arbitration-in-the-securities-industry.pdf. According to
SIFMA, these qualities make FINRA arbitration “less
expensive, more expedient, and just as fair as court-based
litigation.” SIFMA Arbitration Article at 4.

ANALYSIS
The central issue raised by this appeal is whether
Defendants may arbitrate their claims against Oppenheimer.
On the one hand, “a party cannot be required to submit to
arbitration any dispute which he has not agreed so to
submit.” AT&T Techs., Inc. v. Commc’ns Workers of Am.,
475 U.S. 643, 648 (1986) (quoting United Steelworkers of
Am. v. Warrior & Gulf Nav. Co., 363 U.S. 574, 582 (1960)).
On the other hand, as noted, FINRA Rule 12200 obligates
FINRA members like Oppenheimer to submit any “dispute
under the [FINRA] Code” to arbitration when requested by
“customer[s].” Defendants have plainly requested
arbitration, and it is undisputed that their claims, which
concern Oppenheimer’s supervisory obligations under
FINRA, fall within the ambit of a “dispute under the
[FINRA] Code.” Therefore, whether Defendants may force
Oppenheimer into one of FINRA’s arbitral forums turns
solely on the question whether Defendants are “customers”
of Oppenheimer for purposes of Rule 12200.
Defendants, who concede that they have no direct
relationship with Oppenheimer, submit only one theory
through which they might be its customers: They argue that
they have engaged in transactions with Woods, who acts as
an “associated person” of Oppenheimer for purposes of the
12 OPPENHEIMER & CO. INC. V. MITCHELL
FINRA Code. The validity of this theory, which the district
court rejected, occupies the bulk of our analysis here.
Defendants also raise two additional challenges to the
district court’s ruling. First, they argue that, even if they are
not “customers” of Oppenheimer, the district court abused
its discretion by granting a permanent injunction. Second,
they argue that the district court committed legal error by
imposing unsupported legal requirements and making
erroneous factual findings.
We evaluate these arguments in turn. Because we
conclude that they are without merit, we affirm in full the
decision below.
I. Defendants Are Not “Customers” of Oppenheimer.
The first, and primary, question raised by this appeal is
whether Defendants are customers of Oppenheimer for
purposes of FINRA Rule 12200. Defendants concede that
they are not direct customers because they have not
transacted with Oppenheimer. Defendants nevertheless
submit that they are indirect customers of Oppenheimer
because they are customers of Woods, one of
Oppenheimer’s associated persons. The viability of this
theory turns on two issues: whether FINRA Rule 12200
applies to customers of associated persons, and whether
Defendants are actually customers of Woods.
a. An Investor Who Purchases Commodities or
Services from an “Associated Person” of a
FINRA Member Is a “Customer” of the
Member for Purposes of FINRA Rule 12200.
As noted, a FINRA member must arbitrate a dispute if:
(1) “[r]equested by the customer”; (2) “[t]he dispute is
between a customer and a member or associated person of a
OPPENHEIMER & CO. INC. V. MITCHELL 13
member”; and (3) “[t]he dispute arises in connection with
the business activities of the member or the associated
person.” FINRA Rule 12200. This rule plainly provides the
customer of a FINRA member with the right to request and
receive arbitration. Reno, 747 F.3d at 739. Yet “ambiguity
results from the fact that the rule does not specify with whom
the customer must conduct business. That is, as written, the
rule leaves open the possibility that a dispute could arise
between ‘a [member’s] customer and a member’ or between
‘[an associated person’s] customer and a member.’”
Washington Square Sec., Inc. v. Aune, 385 F.3d 432, 436
(4th Cir. 2004) (alteration in original); see also John
Hancock Life Ins. Co. v. Wilson, 254 F.3d 48, 59 (2d Cir.
2001). The FINRA Code offers little insight into this
ambiguity. Its separate rule providing “definitions” of terms
used throughout the Code defines “customer” only in the
negative: “A customer shall not include a broker or dealer.”
FINRA Rule 12100(k).
This ambiguity has important ramifications for the group
of “customers” who are entitled to FINRA arbitration. Only
the large companies that register for FINRA membership are
FINRA members. By contrast, an “associated person” of a
FINRA member includes “any employee of the [member],
except any person whose functions are solely clerical or
ministerial.” FINRA Rule 1011(b). To qualify as a
“customer” for purposes of Rule 12200, must an individual
transact directly with the FINRA member—the entity—
itself? Or may an individual merely transact with one of the
FINRA member’s many non-clerical, non-ministerial
employees—finance professionals, investment advisers, and
anyone else in the member’s substantive employ? This
question not only affects which customers may arbitrate but
which claims they may bring to the fore. As Defendants’
14 OPPENHEIMER & CO. INC. V. MITCHELL
case illustrates, “[i]t is possible that an ‘associated person’
of a FINRA member could have an independent company.”
Centaurus Fin., Inc. v. Ausloos, No. 19-CV-243, 2019 WL
2027271, at *5 (E.D. Wis. May 8, 2019). Does Rule 12200
entitle a customer to arbitrate against a FINRA member
“simply because he purchased [a] good or service from [that
member’s] ‘associated person’ acting on behalf of his or her
own independent company[?]” Id.
The district court answered this question in the
affirmative, and Defendants urge us to reach the same
conclusion. As they note, the FINRA Code offers several
clues that customers are not restricted to those who transact
with FINRA members. First, as noted, the Code’s own
definition of “customer” is non-restrictive. See FINRA Rule
12100(k). That the term is defined to exclude brokers and
dealers, but not defined with reference to FINRA members,
hints at a broad construction. An online FINRA glossary,
though not expressly incorporated by the FINRA Code,
suggests the same conclusion. See UBS Fin. Servs., Inc., 660
F.3d at 650. It defines an “investor”—the prototypical
“customer” of a securities firm—as “[a] person or entity . . .
that transacts business with any member firm and/or
associated person.” Dispute Resolution Glossary, Fin.
Indus. Regul. Auth., https://www.finra.org/
arbitration-mediation/about/arbitration-vs-
mediation/dispute-resolution-glossary (last visited April 16,
2025). If customers are defined to include all non-brokers
and non-dealers, then customers must include investors,
even those that invest with associated persons.
Additional signals may be discerned from the text of
Rule 12200, which makes no apparent distinction between
individuals who transact with members as opposed to their
associated persons. The rule first limits arbitrable claims to
OPPENHEIMER & CO. INC. V. MITCHELL 15
those arising from disputes “between . . . customer[s]
and . . . member[s] or associated person[s].” FINRA Rule
12200 (emphasis added). It then clarifies that these disputes
may “arise[] in connection with the business activities of the
member or the associated person.” Id. (emphasis added).
These signals suggest an intent to encompass the claims of
those who transact with associated persons. Nevertheless, to
the extent that the signals are truly ambiguous, because Rule
12200 “constitutes an ‘agreement in writing’ under the
FAA,” Reno, 747 F.3d at 739 n.1, we “appl[y] ‘the federal
policy favoring arbitration’ when interpreting this
provision.” Waterford Inv. Servs., Inc. v. Bosco, 682 F.3d
348, 353 (4th Cir. 2012) (quoting Aune, 385 F.3d at 435);
see also Wachovia Bank, Nat. Ass’n v. VCG Special
Opportunities Master Fund, Ltd., 661 F.3d 164, 171 (2d Cir.
2011); Multi-Fin. Sec. Corp. v. King, 386 F.3d 1364, 1367
(11th Cir. 2004). Applying this guidance, we resolve “any
doubts concerning the scope of arbitrable issues . . . in favor
of arbitration”—here, in favor of reading Rule 12200
expansively to extend to those who transact with associated
persons. Moses H. Cone Mem’l Hosp. v. Mercury Constr.
Corp., 460 U.S. 1, 24–25 (1983).
Employing similar logic, most of our sister circuits that
have addressed this question have concluded that Rule
12200 applies to the customers of associated persons. The
Second Circuit was an early leader in this regard. In John
Hancock, it applied processes of statutory interpretation and
construction before concluding that “the customer of an
associated person, asserting a claim arising out of the
associated person’s business,” must not be “prohibited”
from “compelling a [FINRA] member to arbitrate under
Rule [12200].” 254 F.3d at 59. The Second Circuit noted
that Rule 12200 was “not only susceptible of [this]
16 OPPENHEIMER & CO. INC. V. MITCHELL
interpretation . . . but require[d] [it].” Id. It rested its
conclusion in part on federal policy under the FAA, and in
part on its determination that “nothing in the language of
Rule [12200], or any other provision of the [FINRA]
Code, . . . compel[led] . . . (or even suggest[ed])” a contrary
result. Id.
Other federal courts of appeal followed the Second
Circuit’s lead. The Sixth Circuit, reasoning that “Rule
[12200] [does not] require[] that defendant-investors be
direct customers of [a FINRA member],” determined that
“an agent or representative of a financial services firm is an
‘associated person’ under [FINRA] Rule [12200] such that a
relationship with the agent entitles the investor to the
arbitration process.” Vestax Sec. Corp. v. McWood, 280
F.3d 1078, 1082 (6th Cir. 2002). The Eleventh Circuit has
likewise affirmed that “the plain language of Rule [12200]
supports the view that the term ‘customer’ refers to either a
member’s or an associated person’s customer, affording
customers of an associated person a right to compel
arbitration against a member.” King, 386 F.3d at 1369. The
Eight Circuit, for its part, has described the “proposition that
customers of associated persons of a firm may compel
arbitration with the firm” as “unremarkable.” Berthel Fisher
& Co. Fin. Servs. v. Larmon, 695 F.3d 749, 753 (8th Cir.
2012). At least three other courts of appeal are in accord,
see Waterford, 682 F.3d at 353; Cal. Fina Group, Inc. v.
Herrin, 379 F.3d 311, 318 (5th Cir. 2004); Miller v. Flume,
139 F.3d 1130, 1136 (7th Cir. 1998), and Oppenheimer
points to none that has reached a different conclusion.
Oppenheimer nevertheless asserts that our circuit, which
has not yet addressed this question, is required by our
precedent to reach a different result. As it observes, although
we have never opined on whether customers include those
OPPENHEIMER & CO. INC. V. MITCHELL 17
who transact with associated persons, we have opined on the
kinds of transactions in which customers must engage.
Specifically, in Reno, we held that “a ‘customer’ is a non-
broker and non-dealer who purchases commodities or
services from a FINRA member in the course of the
member’s FINRA-regulated business activities, i.e., the
member’s investment banking and securities business
activities.” 747 F.3d at 741. Reno involved a claimant that
had employed a FINRA member as an underwriter to issue
debt in the form of auction rate securities. Id. at 735–36.
Responding to the FINRA member’s assertion that the
defendant “was not a ‘customer’ because their relationship
did not relate directly to investment or brokerage services,”
we concluded that the defendant was a customer because the
FINRA member “provided [it with] services in the course of
its securities business activities.” Id. at 739, 741.
Although Reno is relevant, it does not control this case
because it did not raise or address the factually distinct
circumstances presented here. Reno arose in the context of
a dispute between an individual and a FINRA member, and
it did not involve any associated persons. Therefore, it did
not reach or resolve the application of Rule 12200 among
customers of associated persons. See id. at 741. This
rationale also explains the opinion’s holding: Although
Reno defined “customers” as those who transact with
“FINRA member[s],” this definition is not comprehensive
and does not foreclose the application of Rule 12200 to
customers of associated persons. Id. The Second Circuit
reached the same conclusion when asked to reconcile its
decision in John Hancock, which focused on the customers
of associated persons, with prior opinions that had focused
on the customers of FINRA members. 254 F.3d at 60. As it
explained, those prior opinions “d[id] not limit [the court’s]
18 OPPENHEIMER & CO. INC. V. MITCHELL
application of the [FINRA] Code to the entirely distinct set
of facts presented [in John Hancock] any more than [the]
finding that a confession is sufficient evidence of a murder
forecloses a subsequent finding that the testimony of an
eyewitness is sufficient as well.” Id.
For the foregoing reasons, we hold that a “customer,” for
purposes of Rule 12200, includes any non-broker and non-
dealer who purchases commodities or services from a
FINRA member or its associated person. Reno, 747 F.3d at
741. This holding not only aligns with Reno and the rulings
of our sister circuits but further serves the purposes of Rule
12200 by ensuring that access to arbitration is guided by a
clear and administrable rule. As SIFMA notes, arbitration is
valuable because it entails “lower costs, greater efficiency
and speed, and the ability to choose expert adjudicators to
resolve specialized disputes.” Stolt-Nielsen S.A. v.
AnimalFeeds Int’l Corp., 559 U.S. 662, 685 (2010). But if
proceeding to arbitration were to require a fact-intensive
analysis of “customer status,” the “sprawling litigation” that
would likely result could “defeat[] the express goals of
arbitration to yield economical and swift outcomes.”
Citigroup Glob. Mkts. Inc. v. Abbar, 761 F.3d 268, 276 (2d
Cir. 2014). The bright-line definition of “customer”
contemplated here addresses this concern by ensuring that
access to arbitration depends only on the question whether
an individual transacted with a FINRA member or its non-
clerical, non-ministerial employee. See Reno, 747 F.3d at
741; FINRA Rule 12200. To answer this question, “[t]he
only relevant inquiry . . . is whether an account was opened
or a purchase made.” Abbar, 761 F.3d at 276.
OPPENHEIMER & CO. INC. V. MITCHELL 19
b. Defendants Did Not Transact with Woods.
Applying this understanding of the FINRA Code,
Defendants argue that they are customers of Woods, and
therefore of Oppenheimer, because they purchased stock
from Woods during the time that he was employed by
Oppenheimer. The parties do not dispute that Defendants
are not brokers or dealers. They also do not dispute that
Woods was an “associated person” of Oppenheimer at the
time Defendants’ claims arose because Woods was, at that
time, employed by Oppenheimer in a substantive capacity.
See FINRA Rule 1011(b). Therefore, pursuant to our
understanding that FINRA Rule 12200 encompasses the
claims of customers of associated persons, Defendants are
entitled to FINRA arbitration so long as they can
demonstrate a customer relationship with Woods.
The district court concluded that Defendants were not so
entitled because they could not make the necessary showing
of a customer relationship. As noted, Defendants’ specific
claim is that “they purchased a security”—their investments
in Horizon—“from Woods while he was an associated
person of Oppenheimer.” However, the district court found
that “there simply is no evidence of Woods’ participation
such that the Court could conclude he sold Defendants any
commodities or services as required to be ‘customers’ under
FINRA Rule 12200.” In reaching this conclusion, the
district court emphasized the level of interaction that
Defendants had with Woods, the owner of Horizon and
Southport, as compared with Mooney, Defendants’
investment adviser at Southport. The district court
concluded that Mooney was the individual from whom
Defendants purchased their Horizon investments—not
Woods.
20 OPPENHEIMER & CO. INC. V. MITCHELL
We agree. As the district court noted and the record
confirms, Woods did not reach out to Defendants, solicit
them to purchase investments, advise them about Horizon,
or send them information or logistical materials. Nor did
Woods collect payment from Defendants, effectuate their
investments, or earn any fees or commission on their
spending. Simply put, Woods had no role in recruiting,
facilitating, or causing Defendants’ investments in Horizon
to occur. Instead, it was Mooney, Southport’s registered
representative, who did all of these things. He was the
individual responsible for bringing in Defendants’ business,
advising them about Horizon, carrying out their purchase of
securities, and generally overseeing their investment.
Mooney was also Defendants’ sole contact as they went
through the process of investing. Other than a single phone
call between Woods and the Mitchells—a conversation that
Mooney helped arrange, and during which Woods “backed
up exactly what . . . Mooney” had already told Defendants—
Defendants had no contact with Woods and communicated
entirely with Mooney about their investments. 2
2
As Defendants note, the district court failed to account for this
conversation when noting that “[n]one of the defendants testified that
they spoke with Woods or that Woods acted as their broker or advisor in
making their investments in Horizon.” As described, the Mitchells did
speak with Woods, and their conversation with Woods was substantive:
The Mitchells “asked . . . Woods questions about the [Horizon]
investment as part of [their] due diligence into the program,” and Woods
provided answers that encouraged the Mitchells to place their first trades.
Therefore, the district court’s statement that Defendants failed to
“testif[y] that they spoke with Woods . . . in making their investments in
Horizon” is inaccurate. Nevertheless, this error is harmless because
Defendants and Woods had no other interactions that were material to
their investments in Horizon. Therefore, even considering the phone
OPPENHEIMER & CO. INC. V. MITCHELL 21
Based on this cumulative evidence, it is clear that “it was
Mooney who facilitated and caused [Defendants’]
investments to occur, not Woods.” Mooney, unlike Woods,
was not employed by Oppenheimer during the time he
transacted with Defendants. 3 Therefore, because
Defendants were not customers of Woods, and because the
only individual to whom Defendants were customers was not
an “associated person” of Oppenheimer, there is no basis to
conclude that Defendants were customers of Oppenheimer.
See FINRA Rule 12200. This would appear to resolve
Defendants’ claims.
Defendants nevertheless suggest one final way in which
their transactions with Horizon, Mooney, and Woods might
be tied to Oppenheimer. They argue that by investing in
Horizon, an entity that Woods ran and controlled,
Defendants effectively invested in an “alter ego” of Woods
and therefore, by extension, became Woods’s customers.
This argument depends on the unusual suggestion that an
individual may become the “customer” of an associated
person of a FINRA member merely by purchasing stock in a
company that the associated person owns or substantially
controls. See Ranza v. Nike, Inc., 793 F.3d 1059, 1073 (9th
Cir. 2015).
We reject Defendants’ “alter ego” theory. As a threshold
matter, the district court expressly discarded this theory, both
interaction between the Mitchells and Woods, there is no basis to
conclude that the Mitchells—or the Hoppers, who had no contact with
Woods—were Woods’s customers.
3
Mooney was employed by Oppenheimer from 2007 to 2010, years
before Defendants’ claims arose. Defendants make no contention that
Mooney’s prior employment relationship with Oppenheimer renders him
an “associated person” for purposes of their claims.
22 OPPENHEIMER & CO. INC. V. MITCHELL
in connection with Defendants’ motion for summary
judgment and their motion for a preliminary injunction.
Because Defendants do not clearly challenge that conclusion
in their opening brief, it is waived. Dennis v. BEH–1, LLC,
520 F.3d 1066, 1069 n.1 (9th Cir. 2008). Nevertheless, even
if considered on its merits, Defendants’ theory is meritless.
The theory lacks support from the FINRA Code and has
never been considered or endorsed by any federal court of
appeal. Further, the theory is not logical: If true, it would
lead to the odd result that any investor who purchases stock
in a company becomes the “customer” of those individuals
in control of the company—and, by extension, the customer
of any FINRA members employing those individuals.
Because the FINRA Code clearly does not contemplate that
broad result, see, e.g., King, 386 F.3d at 1370, Defendants’
“alter ego” theory is unsupported.
For the foregoing reasons, because Defendants did not
transact with Woods, they are not the customers of any
“associated person” of Oppenheimer. As a result,
Defendants are not entitled to arbitration pursuant to FINRA
Rule 12200.
II. The District Court Did Not Abuse Its Discretion by
Entering a Permanent Injunction.
Defendants next suggest that, these conclusions aside,
the district court still abused its discretion by entering a
permanent injunction enjoining them from arbitrating their
claims. Defendants’ argument relies on eBay, which held
that a plaintiff who seeks a permanent injunction must
“demonstrate: (1) that it has suffered an irreparable injury;
(2) that remedies available at law, such as monetary
damages, are inadequate to compensate for that injury;
(3) that, considering the balance of hardships between the
OPPENHEIMER & CO. INC. V. MITCHELL 23
plaintiff and defendant, a remedy in equity is warranted; and
(4) that the public interest would not be disserved by a
permanent injunction.” 547 U.S. at 391.
Defendants argue that two of the eBay requirements are
not satisfied here, but both arguments are unpersuasive
because they rely on Defendants’ underlying contention that
they are “customers” of Oppenheimer. Defendants first
argue that Oppenheimer would not be harmed by arbitrating
their claims because Oppenheimer, in seeking FINRA
membership, agreed to arbitrate the claims of its customers
pursuant to FINRA Rule 12200. But for the reasons that
have been discussed, Defendants are not customers of
Oppenheimer. Therefore, Oppenheimer has no obligation to
arbitrate Defendants’ claims. See FINRA Rule 12200.
Under these circumstances, the district court did not abuse
its discretion by concluding that forcing Oppenheimer to
submit to arbitration would cause it to suffer irreparable
losses in the form of time, money, and related resources. See
McLaughlin Gormley King Co. v. Terminix Int’l Co., 105
F.3d 1192, 1194 (8th Cir. 1997); Md. Cas. Co. v. Realty
Advisory Bd. on Lab. Rels., 107 F.3d 979, 984–85 (2d Cir.
1997).
Defendants also argue that a permanent injunction is
unsupported because the FAA “embodies a clear federal
policy,” Simula, Inc. v. Autoliv, Inc., 175 F.3d 716, 719 (9th
Cir. 1999), in favor of arbitrating “valid, irrevocable, and
enforceable” agreements to arbitrate, 9 U.S.C. § 2. But this
argument also depends on Defendants’ “customer” status
because a valid “agreement to arbitrate exists only if a
customer requests arbitration from a [FINRA] member.”
UBS Fin. Servs., Inc. v. Carilion Clinic, 706 F.3d 319, 324
n.2 (4th Cir. 2013). Because Defendants are not customers
of Oppenheimer, there is no arbitration agreement between
24 OPPENHEIMER & CO. INC. V. MITCHELL
the parties, and Defendants’ suggested rationale does not
apply. See id. In its absence, the district court did not abuse
its discretion by determining that policy disfavors forcing a
party to arbitrate against its own wishes. Id.; see also AT&T
Techs., Inc., 475 U.S. at 648–49.
III. The District Court Did Not Err by Introducing
New Legal Requirements or Reaching Erroneous
Factual Findings.
Defendants finally suggest that, concerns about their
own “customer” status aside, the district court further erred
by introducing unsupported requirements for the legal
definition of a “customer” and making factual findings that
are unsupported by the record. Both of these arguments are
without merit.
Defendants first contend that the district court committed
legal error by “improperly impos[ing] additional
requirements beyond the definition [of ‘customer’] carefully
crafted by the [Reno] Panel.” Defendants identify only one
such requirement: the district court’s alleged insistence that
Defendants “deal[] in person with John Woods” in order to
qualify as his customers. This argument is unsupported
because the district court imposed no requirement that
Defendants engage in in-person interactions with Woods.
Nevertheless, the district court did consider whether
Defendants engaged in personal interactions with Woods
that could be seen as consistent with a purchase-based
customer relationship. This consideration was appropriate
because the “relevant inquiry” for purposes of Rule 12200
is, as noted, whether an individual practically transacted with
a FINRA member or its associated person. Abbar, 761 F.3d
at 276; see also Reno, 747 F.3d at 741; King, 386 F.3d at
1370.
OPPENHEIMER & CO. INC. V. MITCHELL 25
Defendants also contend that the district court committed
legal error by making erroneous “factual findings” regarding
their interactions with Woods. Defendants specifically
argue that the district court erred by finding that
(1) “Defendants identif[ied] no evidence that they purchased
any commodity or service from Woods” and that (2) Woods
“ha[d] not been shown to have any active role in the actual
purchases.” As a threshold matter, it is not clear that these
statements are findings of fact, as opposed to summaries of
the record. Nevertheless, Defendants are correct that in
granting summary judgment, a district court may make
findings of fact for the “limited purpose [of] . . .
pinpoint[ing] the undisputed facts supporting the summary
judgment.” Swarner v. United States, 937 F.2d 1478, 1481
(9th Cir. 1991). This process underpins the “threshold
inquiry of determining whether there is the need for a trial—
whether, in other words, there are any genuine factual issues
that properly can be resolved only by a finder of fact.”
Anderson v. Liberty Lobby, Inc., 477 U.S. 242, 250 (1986).
The district court properly conducted that inquiry here by
assessing the undisputed evidence and concluding that it
reflected no signs of a customer relationship with Woods.
CONCLUSION
For the foregoing reasons, we conclude that a
“customer,” for purposes of FINRA Rule 12200, includes
any non-broker and non-dealer who purchases commodities
or services from a FINRA member or its associated person.
Nevertheless, we find that Defendants are not customers of
Oppenheimer, a FINRA member, because they did not
purchase commodities or services from John Woods or any
other associated person of Oppenheimer. Therefore, we
agree with the district court that Defendants were not entitled
to arbitrate their claims against Oppenheimer pursuant to
26 OPPENHEIMER & CO. INC. V. MITCHELL
FINRA Rule 12200. We also affirm the district court’s
permanent injunction prohibiting Defendants from
arbitrating their claims. Because we discern no other errors
in the district court’s analysis or factual findings, we affirm.
AFFIRMED.
