       The story is a familiar one. Individuals and entities desperate for money came

across nefarious characters who claimed to have money to lend. The money could be

theirs if they paid handsome sums in the form of upfront, nonrefundable “loan

commitment fees.” But when the money never came and they realized that the

lenders had never intended to fund their loans, the borrowers sued as a class against

the lenders and their leaders. They sought relief under the Racketeer Influenced and

Corrupt Organizations Act (“RICO”), 18 U.S.C. §§ 1961–68; and secured a collective

jury verdict just shy of $8.5 million. After factoring in treble damages and pretrial

settlements, the class obtained a final judgment exceeding $24 million.

       Defendants Sandy Hutchens, Tanya Hutchens, and Jennifer Hutchens 1—the

three-member family who purportedly orchestrated the loan scam—now challenge

certain of the district court’s rulings in this years-long litigation to avoid paying all or

part of the judgment against them. Almost all of those challenges fail, including their

challenges to the jury’s verdict, class certification, proximate causation, and the

application of the equitable unclean hands defense.

       Even so, we agree with the Hutchenses’ position on the district court’s

imposition of a constructive trust on some real property allegedly bought with the

swindled fees. We therefore affirm in part, reverse in part, and remand to the district

court for entry of a revised judgment.

      The class’s version of events paints the Hutchenses as cunning con artists who

puppeteered the advance-fee loan scam from afar. According to the class, Sandy

Hutchens—the family’s patriarch—was the scam’s primary engineer. He claims that

he began his career nearly forty years ago as a mortgage broker and has extensive

experience facilitating loans between private lenders and hopeful borrowers.

      But Sandy also had an extensive criminal history. The class presented

evidence that Sandy’s criminal record reflected convictions for theft, fraud, public

mischief, forgery, and trafficking narcotics. Sandy’s criminal record would have

likely scared off potential borrowers from the outset. As the class rhetorically asked

the jury at trial, “[w]hat rational person would pay hundreds of thousands of dollars

in advance fees to someone with multiple criminal convictions for fraud and

forgery?” Sandy thus hid his criminal past from borrowers. And the class argues

that he did so by using various aliases, such as Moishe Alexander, Ben Avraham, and

Frederick Merchant.

      Sandy also did not have any money to lend. So the other part of the class’s

theory is that Sandy—generally working under his aliases—dramatically

misrepresented how much money he had at his disposal. According to the class,

Sandy and those working with him fabricated fake financial statements suggesting he

and his companies had tens of millions of dollars to lend. The conspirators would

then furnish those financial statements to borrowers upon request.



                                                3
      In any event, once Sandy had the scam in full swing, his “formula” for duping

hopeful borrowers was not complicated. CGC Holding Co. v. Broad & Cassel, 

, 1082 (10th Cir. 2014). 2 First, Sandy created several different “issuing

entities.” The “issuing entities” served as the phony lenders. Sandy made five such

entities over the years: (1) Canadian Funding Corporation, (2) 308 Elgin Street Inc.,

(3) First Central Mortgage Funding Inc., (4) Northern Capital Investment Ltd., and

(5) Great Eastern Investment Fund LLC. All five entities shared two common traits:

they had no money to lend, and they used fake business addresses while operating out

of Sandy’s home in Toronto.

      Second, “a potential borrower would submit a loan application to one of [the

five] issuing entities through a loan broker.”

Canadian

lenders from soliciting borrowers directly, so Sandy had to use intermediary brokers

to keep up the issuing entities’ appearances of legitimacy. Sometimes just one broker

would serve as the conduit; sometimes several would. And no matter how many

intermediary brokers participated in the chain of solicitation, a hopeful borrower

would eventually encounter one of Sandy’s issuing entities.

entity would extend a loan commitment agreement to the

potential borrower.

the objective of the scam materialized because

in the affirmative.

the loan commitment agreement required the borrower to pay, among other fees, “an

up-front, non-refundable payment known as a ‘loan commitment fee.’”

the issuing entity would terminate the loan commitment

agreement “for failing, in one form or another, to comply with the conditions of the

agreement.”

course, claims that Sandy had intended all along to

terminate their agreements and never fulfill their loans. In their view, once Sandy

had the borrowers’ advance fees in hand, he had accomplished his only goal. Sandy

ultimately walked away with over $8.4 million of the class’s loan commitment fees

after committing to over $3 billion in loans he could not fund.

      But Sandy was not the only person in on the scheme. Sandy’s wife Tanya and

daughter Jennifer also purportedly played various roles. Jennifer, for instance,

admitted that she had worked as a receptionist performing much of the clerical work

for some of the issuing entities. She also admitted that she had posed as the

“manager of underwriting” when corresponding with some borrowers to get more

information from them.

      Tanya’s involvement was not as clear. Unlike Jennifer, Tanya denied

participating in the scheme. But the class presented evidence that connected her to

Sandy’s plans. One of Sandy’s ex-business partners, for instance, testified that he

had worked with both Sandy and Tanya “nearly every day” for two-and-a-half years

during the scam’s infancy. And he also testified that Tanya’s actions over that

time—such as “typ[ing] up . . . loan commitments and letters of intent”—had led him

to believe she had been “an equal partner in the business.” Further, the class showed

                                              5
the jury a letter from Sandy to his former attorney in which he referenced Tanya. In

the letter, Sandy requested Tanya’s appearance at a meeting about the “Internet

presence” of one of the issuing entities—again suggesting that Tanya was involved in

the scam.

      Yet according to the class, Tanya’s primary connection to the scheme was her

receipt of “dirty money.” The class maintained that Sandy, acting through the

issuing entities, had funneled a lot of the swindled fees to Tanya. And receiving and

benefitting from stolen money suggests participation in the scheme. In the class’s

view, that tended to show that Tanya had at least been a lower level participant in the

scam. But taken in tandem with the other evidence of her involvement—the

testimony of Sandy’s ex-business partner and Sandy’s letter to his attorney—Tanya’s

consistent receipt of the swindled fees confirmed that Tanya “was a continuing

partner of Sandy’s.”

      Whatever the case, Tanya ended up investing her share of the money in

different Canadian properties. Those properties included Tanya and Sandy’s house

and twenty-three other locations scattered around greater Ontario. In fact, several

other people ended up receiving a portion of the swindled fees from Sandy, including

Sandy’s own children, Tanya’s mother, and other family members—and they also

ended up investing in the same properties. And for that reason, the class contends

that those properties constitute a large chunk of the borrowers’ advance fees. Indeed,

the class observes that the Hutchenses acquired all the properties after the borrowers

had remitted their fees. And given that the Hutchenses were previously unable to

                                              6
afford such a vast collection of real estate—as we mentioned above, Sandy

artificially inflated his net worth to earn the trust of the borrowers—the class

maintains that the only reasonable explanation is that they used the swindled fees to

buy the properties. After all, the combined market value of the properties was over

$16 million at one point, and neither discovery nor trial unearthed a legitimate source

of funding that could have explained such hefty purchases. 3

      But the Hutchenses did not directly purchase most of those properties we

describe above. Instead, they often executed the purchases through various

companies. To be clear, those companies were not the five issuing entities but rather

unrelated entities that the Hutchenses had created to purchase and hold the properties.

So, strictly speaking, these entities, not the Hutchenses, owned many of the

properties.

      But even as the Hutchenses sought to protect their ill-gotten gains, the

borrowers started getting suspicious. So the borrowers joined as a class and sued in

Colorado federal court to retrieve their advance fees. At first, the class asserted

multiple claims against multiple parties. But after years of litigation, only the class’s

two RICO claims against the Hutchenses remained on the eve of trial.

      The class ultimately prevailed at trial, but despite its victory, it still faced the

uphill battle of collecting its judgment from the Hutchenses. So, as a remedy, the




      3
        At trial, Tanya testified “that she bought the properties with her own funds.”
But the district court “did not find [that] testimony to be credible.”

district court imposed a constructive trust on the properties and entities described

above.

         The Hutchenses now appeal, raising several issues, including challenges to

personal jurisdiction, sufficiency of the evidence, causation, class certification, and

remedies. To that end, they begin by trying to protect Tanya. As to Tanya, the

Hutchenses first challenge personal jurisdiction, followed by challenges to the jury’s

RICO verdict against her, including the availability of class-wide liability. After

concluding their arguments about Tanya, the Hutchenses turn to the statutory

requirements under RICO, challenging whether the class satisfied RICO’s

distinctness and proximate causation requirements. The Hutchenses follow with

argument regarding the equitable defense of unclean hands—primarily, whether it

defeats the class’s RICO claims. Finally, the Hutchenses challenge the district

court’s imposition of a constructive trust.

         We address each in turn.

                                              II.

         The Hutchenses first contend that because Tanya had no minimum contacts

with the United States, the district court lacked personal jurisdiction over her. We

review the exercise of personal jurisdiction over a foreign defendant de novo.

Marcus Food Co. v. DiPanfilo, 

, 1166 (10th Cir. 2011).

         When a plaintiff’s claims arise under federal law and the defendant is not

subject to the jurisdiction of any state court of general jurisdiction, Federal Rule of

Civil Procedure 4(k)(2) provides for federal long-arm jurisdiction if the plaintiff can

                                                    8
show that the exercise of jurisdiction comports with due process. Compania de

Inversiones Mercantiles S.A. v. Grupo Cementos de Chihuahua, S.A.B. de C.V., ___

F.3d ___, ___ n.1 (10th Cir. 2020) (discussing GCIU-Employer Ret. Fund v.

Coleridge Fine Arts, 700 F. App’x 865, 867–68 (10th Cir. 2017) (unpublished)).

Tanya admits that the class’s claims arise under federal law. She likewise contends

she is not subject to personal jurisdiction in Colorado, so Rule 4(k)(2) applies in this

case. When a “defendant contends that he cannot be sued in the forum [state] and

refuses to identify any other [forum state] where suit is possible, then the federal

court is entitled to use Rule 4(k)(2),” so long as the exercise of federal jurisdiction

satisfies Fifth Amendment due process standards. 4 Compania de Inversiones

Mercantiles, ___ F.3d at ___ (quoting ISI Int’l, Inc. v. Borden Ladner Gervais LLP,

, 552 (7th Cir. 2001)).

      To determine whether the exercise of federal jurisdiction over Tanya satisfies

due process, we must determine whether Tanya had minimum contacts with the

United States. The minimum contacts standard allows a federal court to exercise

specific personal jurisdiction over a foreign defendant only if the defendant

purposely directed her activities at the forum and the plaintiff’s injuries arose from

the defendant’s forum-related activities. Dudnikov v. Chalk & Vermilion Fine Arts,

Inc., 

, 1071 (10th Cir. 2008).




      4
        The parties do not argue that any meaningful distinction exists between the
Fifth and Fourteenth Amendment due process standards.
                                                9
      Here, the Hutchenses directed the activities involving their RICO conspiracy at

the United States. Although Tanya’s involvement in the scheme was not as clear cut,

the class presented evidence that she was an integral player. The class presented

evidence that Tanya and her husband had conducted the scheme from their home

office in Toronto and that Tanya had participated in the scheme by preparing loan

commitment letters directed at U.S. borrowers. Moreover, Tanya received into her

accounts the net proceeds of the advance fees. Further, the class presented evidence

from one of Sandy’s ex-business partners Martin Lapedus, who testified that he had

worked with both Sandy and Tanya “nearly every day” for two-and-a-half years

during the scam’s infancy. And he also testified that Tanya’s actions over that

time—such as “typ[ing] up . . . loan commitments and letters of intent”—had led him

to believe that she had been “an equal partner in the business.” The class also showed

the jury a letter from Sandy to his former attorney that referenced Tanya. In the

letter, which Sandy wrote during the scam’s heyday, Sandy requested Tanya’s

presence at a meeting about the “Internet presence” of one of the issuing entities—

again showing that Tanya was in on the scam.

      The class also maintained that Sandy, acting through the issuing entities, had

funneled a large portion of the swindled fees to Tanya. And receiving and

benefitting from stolen money—or as the class put it, “sucking the money out of” a

fraudulent scheme—tended to show that Tanya had been a participant in the scam.

When combined with the other evidence of her involvement—the testimony of

Sandy’s ex-business partner and Sandy’s letter to his attorney—Tanya’s receipt of

                                             10
the swindled fees over the years showed that she directly participated in and

benefited from the scheme.

       We are not saying that Tanya had minimum contacts with the United States

because of Sandy’s contacts. Instead, she had minimum contacts with the United

States because her own actions—as a participant in the conspiracy—were directed at

the United States and its citizens. Further, the class’s claims, and their

accompanying injuries, arose because of the Hutchenses’ advance-fee loan scheme.

We therefore conclude that the class’s injuries arose out of Tanya’s forum-related

activities, as a co-conspirator in the scheme.

       The next issue we must address is whether the exercise of jurisdiction was

reasonable. “Even when a defendant has purposely established minimum contacts

with a forum state, ‘minimum requirements inherent in the concept of fair play and

substantial justice may defeat the reasonableness of jurisdiction.’” TH Agric. &

Nutrition, LLC v. Ace European Group Ltd., 

, 1292 (10th Cir. 2007)

(quoting Burger King Corp. v. Rudzewicz, 

, 477–78 (1985)). We

consider: (1) “the burden on the defendant,” (2) “the forum state’s interest in

resolving the dispute,” (3) “the plaintiff's interest in receiving convenient and

effective relief,” (4) “the interstate judicial system's interest in obtaining the most

efficient resolution of controversies,” and (5) “the shared interest of the several states

in furthering fundamental substantive social policies.” OMI Holdings, Inc. v. Royal

Ins. Co. of Canada, 

, 1095 (10th Cir. 1998). A defendant must present



                                                 11
a “compelling” case that these factors render jurisdiction unreasonable. Compania de

Inversiones Mercantiles, ___ F.3d at ___ (citing Burger 

).

       In challenging jurisdiction, Tanya claims no evidence exists that she had any

contacts with the United States, an argument we reject above. Tanya fails to argue,

let alone alert us to any facts, on the reasonableness of jurisdiction. Nor does she

address any of the above-listed factors. Given that a defendant “must present a

compelling case” that exercising jurisdiction was unreasonable, Tanya’s failure to

address or argue the issue seals her fate. Bronson v. Swensen, 

, 1104

(10th Cir. 2007) (“[W]e routinely have declined to consider arguments that are not

raised, or are inadequately presented, in an appellant’s opening brief.”). The class

presented sufficient evidence of minimum contacts with the United States through

her role as a player in the advance-fee loan scheme. 5 We conclude that the exercise

of personal jurisdiction over Tanya satisfied due process.

                                           III.

       The Hutchenses next claim that no evidence supports the jury’s RICO verdict

against Tanya. We review sufficiency of the evidence claims de novo. Johnson v.

Unified Gov’t of Wyandotte Cnty./Kansas City, 

, 728 (10th Cir. 2004)

(“We review the denial of a motion for judgment as a matter of law based on the

ground of insufficiency of the evidence de novo, using the same legal standard as the

district court.”).



       5
           Tanya was the only defendant who appeared at trial.
                                                  12
      RICO makes it “unlawful for any person employed by or associated with any

enterprise engaged in, or the activities of which affect, interstate or foreign

commerce, to conduct or participate, directly or indirectly, in the conduct of such

enterprise’s affairs through a pattern of racketeering activity.” 18 U.S.C. § 1962(c).

In sum, a violation of § 1962(c) consists of: (1) conduct (2) of an enterprise

(3) through a pattern (4) of racketeering activity. And § 1962(d) prohibits a person

from conspiring to violate § 1962(c).

      The word racketeering tends to evoke images of mobsters and organized

criminals, and true enough, RICO—at least initially—“was an aggressive initiative to

supplement old remedies and develop new methods for fighting crime.” Sedima,

S.P.R.L. v. Imrex Co., 

, 498 (1985); see also

(Powell, J.,

dissenting) (observing that “mobsters . . . were the clearly intended target of” RICO).

But the plain language of RICO defines racketeering far more broadly in a way that

allows the statute to “reach both legitimate and illegitimate” businesses.

(internal quotation marks omitted). Indeed, among many other qualifying acts, RICO

defines a racketeering activity as “any act which is indictable under” the federal

statute outlawing wire fraud—a crime that any modern business could commit. 18

U.S.C. § 1961(1)(B); see also 18 U.S.C. § 1343 (outlawing wire fraud).

      The class pursued RICO claims based on the theory that the Hutchenses had

engaged in wire fraud by using “wire transfers, e-mail, telephone, Internet, and

facsimiles” to defraud the class members of their advance fees. As they reasoned,

RICO allowed the class to get their fees back because the statute allows any person

                                               13
injured “by reason of” a RICO violation to bring a civil suit in federal court and

“recover threefold the damages” against the responsible parties. 18 U.S.C. § 1964(c).

      But proving a RICO violation requires more than racketeering activity alone.

For one thing, the class also had to establish a pattern of racketeering activity, which

RICO defines as “at least two acts of racketeering activity” within a ten-year period.

18 U.S.C. § 1961(5); see also 18 U.S.C. § 1962 (requiring “a pattern of racketeering

activity” for every type of RICO violation). Further, under 18 U.S.C. § 1962(c)—the

subsection giving rise to the class’s first RICO claim—the class had to show that the

Hutchenses “conduct[ed]” an “enterprise” through that pattern of racketeering

activity. 18 U.S.C. § 1962(c). And finally, if the class hoped to prevail under

18 U.S.C. § 1962(d)—the subsection supporting the class’s second RICO claim—

they had to show that the Hutchenses “conspire[d] to violate” RICO in some way.

18 U.S.C. § 1962(d) (emphasis added).

      The Hutchenses claim that the class presented no evidence that Tanya violated

§ 1962(c) and § 1962(d). We disagree for several reasons. The class presented

evidence that the Hutchenses—including Sandy, Jennifer, and Tanya—agreed to a

scheme in which some conspirators would commit predicate acts (wire fraud) and

others would provide support. So even though Tanya’s involvement was not as clear

cut, as discussed above, the class’s evidence showed that Tanya had participated in

the operation or management of the enterprise in a supporting role and sufficiently

connected her to Sandy’s plans. “A conspiratorial agreement . . . need not be express

so long as its existence can plausibly be inferred from the defendant[’s] words and

                                              14
actions and the interdependence of activities and persons involved.” United States v.

Smith, 

, 1273 (10th Cir. 2005) (alteration in original and citation

omitted) overruled on other grounds by Boyle v. United States, 

, 948–49

(2009). Here, a plausible inference exists that Tanya participated in the

conspiratorial agreement based on the testimony of Sandy’s ex-business partner about

Tanya’s role, as well as Sandy’s correspondence regarding Tanya’s presence at a

meeting about an entity’s “Internet presence.”

      The class also presented evidence that Tanya had knowingly received money

generated by the co-conspirators’ activities because Sandy and the issuing entities

directed the lion’s share of the swindled fees directly to her. Thus, the class showed

that Tanya not only drafted loan commitments and letters of intent in the early days

of the scheme, but she also repeatedly received the fruits of the enterprise over the

years. The class’s evidence apparently led the jury to believe that Tanya had

conspired to violate § 1962(c). Moreover, just because Tanya played a supporting

role does not relieve her of responsibility for her involvement in the scam. Salinas v.

United States, 

, 64 (1997). “[S]upporters are as guilty as the

perpetrators.”

evidence, we conclude that the class presented

sufficient evidence to sustain the jury’s RICO verdict against Tanya. 6


      6
        The Hutchenses make two more arguments regarding class-wide liability and
the class period. First, they argue that the class failed to present sufficient evidence
to support class-wide liability against Tanya. Again, we disagree. The class
presented sufficient evidence of Tanya’s involvement as a co-conspirator in the
advance-fee loan scheme. And we upheld the district court’s class certification,
concluding that the borrowers had demonstrated commonality and predominance, as

                                          IV.

      The Hutchenses next argue that the class failed to satisfy RICO’s distinctness

and proximate causation requirements. They also claim the district court adopted an

unknown comparative-fault concept of the unclean hands doctrine and precluded

them from asserting the doctrine as a defense at trial. Consequently, the Hutchenses

claim the district court erred in denying their motions for summary judgment and

judgment as a matter of law on these issues. We review these claims de novo. 7

; Applied Genetics Intern., Inc. v. First Affiliated Sec., Inc.,

, 1241 (10th Cir. 1990); Haberman v. Hartford Ins. Grp., 

, 1264 (10th Cir. 2006).

                                           A.

      Before the district court, the class alleged that the issuing entities were

Sandy’s alter ego and asked the district court to disregard their corporate form. The

Hutchenses claim that these alter-ego allegations destroyed the person/enterprise

distinction that RICO requires. Section 1962(c) requires a plaintiff to prove the


required by Rule 23. CGC Holding Co., 

–99. Second, the
Hutchenses argue that the district court abused its discretion in not amending the
class period. But they fail to cite any adequate basis for their argument, let alone
relevant case law, showing how the district court abused its discretion. 

(stating that we routinely “decline[] to consider arguments that are not
raised, or are inadequately presented, in an appellant’s opening brief”). As a result,
we reject the Hutchenses’ arguments challenging class-wide liability and the class
period.
       7
         Though neither party briefed the proper standard of review, we ordinarily
review application of the unclean hands doctrine for abuse of discretion. Haynes

, 957 (10th Cir. 2009).
But we review de novo the legal determinations underlying the court’s decision.

existence of two distinct entities: a “person” and an “enterprise.” Cedric Kushner

Promotions, Ltd. v. King, 

, 161 (2001). The Hutchenses argue that

because the class also claimed that the issuing entities were Sandy’s alter ego, those

entities were not distinct or separate from Sandy himself. And without the existence

of a separate “person” and “enterprise,” the class cannot prevail on their RICO

claims.

       We reject the Hutchenses’ argument as contrary to RICO’s basic purpose. The

Supreme Court has stated that RICO “protects the public from those who would

unlawfully use an ‘enterprise’ (whether legitimate or illegitimate) as a ‘vehicle’

through which ‘unlawful . . . activity is committed.’”

(quoting Nat’l Org.

for Women, Inc. v. Scheidler, 

, 259 (1994)). And the Court has

acknowledged that the “corporate owner/employee, a natural person, is distinct from

the corporation itself, a legally different entity with different rights and

responsibilities due to its different legal status.”

. 
Thus, RICO “requires no

more than the formal legal distinction between ‘person’ and ‘enterprise’ (namely,

incorporation),” which is present here.
 Id. at 165.
       The issuing entities included CFC (formed in 2004), 308 Elgin (formed in

2006), FCMF (formed in 2006), Northern Capital (formed in 2010), and GEIF

(formed in 2011). Each issuing entity was distinct—i.e., a corporation with its own

legal existence. We find “nothing in RICO that requires more ‘separateness’ than

that.”
 Id. at 158 
(“[L]inguistically speaking, the employee and the corporation are

different ‘persons’” because “[i]ncorporation’s basic purpose is to create a legal

                                                17
entity distinct from those natural individuals who created the corporation, who own,

or whom it employs.” (Id. at 159)). The Hutchenses’ position would allow an

individual—like Sandy—to avoid RICO liability by using shell companies to conduct

criminal enterprises. And while using shell companies as shams to perpetuate frauds

might eliminate any separateness between the wrongdoer and his shell corporation in

the business corporations context (i.e., through veil piercing), it does not destroy the

separateness that RICO requires. Such a position would undermine RICO’s purpose

of protecting “the public from those who would unlawfully use an ‘enterprise’

(whether legitimate or illegitimate)” to commit unlawful activity.
 

. 
We

thus reject the Hutchenses’ argument that the class’s alter-ego allegations destroyed

any separateness between Sandy and the issuing entities under RICO. 8

                                           B.

      The Hutchenses next challenge causation. RICO requires that a plaintiff prove

both but-for and proximate causation. CGC Holding Co., 
LLC, 773 F.3d at 1088
.

The Hutchenses contend the class failed to prove proximate causation. The Supreme

Court has held that when a court evaluates a RICO claim for proximation causation,

we must ask “whether the alleged violation led directly to the plaintiff’s injuries.”
 Id.

(quoting Anza v. 
Ideal Steel Supply Corp., 
547 U.S. 451
, 461 (2006)). The



      8
         The D.C. Circuit rejected a similar argument in United States v. Philip Morris
USA, Inc., 
566 F.3d 1095 
(D.C. Cir. 2009). There, the D.C. Circuit stated that
Cedric Kushner held that “an individual sole shareholder,” like Sandy, “is
sufficiently distinct from his alter-ego corporation[s] to sustain RICO liability.”

Hutchenses argue that the loan applicants (members of the class) would not have

qualified for the loans because legitimate reasons existed to decline to fund each of

the loans. And the class members were aware that their advance fees were non-

refundable should they not qualify. Thus, because the loan applicants would have

lost their fees regardless of the alleged RICO violation, the Hutchenses argue that the

class cannot show the alleged RICO violation directly led to their injuries.

       The Hutchenses’ argument misses the mark. The operative question is whether

the class members would have applied for the loans in the first place had they known

Sandy was a career criminal and that the issuing entities could not fund the loan

commitments. If the Hutchenses had not made these misrepresentations, we can

conclude that the class members would not have applied for the loans and would not

have lost any of their fees.
 Id. at 1081. 9
       With this in mind, we decline the Hutchenses’ invitation to reframe the

relevant question. The Hutchenses fraudulently induced the class members to enter

into loan commitments. And so the class members paid advance fees on loans that

the Hutchenses would not and could not fund. As we stated in our prior opinion

upholding class certification in this case, “no rational economic actor” would have



       9
         We previously upheld class certification because class members could
establish causation based on the theory that “no rational economic actor would enter
into a loan commitment agreement with a party they knew could not or would not
fund the loans.” CGC Holding Co., 
LLC, 773 F.3d at 1081
. We also held that the
class’s “payment of up-front fees allows for a reasonable inference that the class
members relied on lenders’ promises, which later turned out to be
misrepresentations.”
 Id.
                                              19
entered into such a loan commitment agreement.
 Id. Accordingly, the Hutchenses’
misrepresentations directly caused the class to suffer monetary damages.

                                           C.

      The Hutchenses also allege that the district court precluded them from

asserting the equitable defense of unclean hands by applying an unknown

comparative-fault concept. The district court held it would be “inequitable, indeed an

undeserved windfall, to permit defendants’ success at identifying the described

omissions in five applications to be sufficient to negate liability for massive fraud.”

The district court judge, however, stated he would not “close [his] mind to the

possibility that evidence might support intentional misrepresentation by a particular

applicant that rises to the point that an unclean hands defense can be asserted against

that applicant.”

      The unclean hands doctrine means, in general, that equity will not aid a party

whose conduct has been unlawful, unconscionable, or inequitable. 10 Houston Oilers,

Inc. v. Neely, 
361 F.2d 36
, 42 (10th Cir. 1966). But the doctrine “does not exclude

all wrongdoers from a court of equity nor should it be applied in every case where the

conduct of a party may be considered unconscionable or inequitable.”
 Id. And

district courts 
have discretion in deciding whether to apply the unclean hands

doctrine. Id.; see also Haynes Trane Serv. Agency, 
Inc., 573 F.3d at 957
.


      10
         The class argues that the unclean hands defense should not apply in a civil
RICO case. We decline to take up the issue today because even if the unclean hands
doctrine applies in this context, the district court did not abuse its discretion in
refusing to apply it.
                                                20
      Here, the district court did not abuse its discretion in refusing to apply the

unclean hands doctrine. The district court considered the Hutchenses’ evidence and

determined that they had failed to show that any class member intentionally or

knowingly omitted or misrepresented material information in his or her loan

application. The district court also concluded that the Hutchenses did not show that

any alleged fraud so affected the balance of equities that it warranted dismissal of a

class action involving more than 100 defrauded loan applicants.

      Ultimately, the Hutchenses identify no evidence convincing us that the district

court abused its discretion in not applying the equitable defense of unclean hands.

Besides their failure to identify any evidence showing class members intentionally or

knowingly misrepresented the information on their applications, the Hutchenses fail

to address how the unclean hands doctrine can apply when the purported

misrepresentations did not influence the Hutchenses’ behavior. In the end, no matter

if the applications were one hundred percent true or full of lies, the Hutchenses never

intended to (and in fact could not) fund the loans. In this context, we have no trouble

concluding the district court properly exercised its discretion when it refused to apply

the unclean hands doctrine.

                                           V.

      The Hutchenses finally challenge the district court’s imposition of a

constructive trust on many tracts of real property. “A constructive trust is an

equitable remedy devised to prevent unjust enrichment and compel restitution of

property that in equity and good conscience does not belong to the Defendant.”

Amdura Nat’l Distrib. Co. v. Amdura Corp. (In re Amdura Corp.), 
75 F.3d 1447
,

1451 (10th Cir. 1996) (citation omitted). Although they raise several different

arguments, we ultimately need consider only two.

                                           A.

      The Hutchenses first argue that a court cannot attach a constructive trust to

property that a nonparty legally owns without allowing the nonparty to defend itself.

Thus, because nonparties own most of the real estate that is subject to the

constructive trust, and also because those nonparties could not speak out against the

constructive trust, the Hutchenses maintain that the district court abused its discretion

by attaching that equitable remedy to the nonparties’ real estate. See United States v.

Andrews, 
530 F.3d 1232
, 1238 (10th Cir. 2008) (“Because imposition of a

constructive trust is an equitable remedy, we review the district court’s decision for

abuse of discretion.”). We agree.

      In addressing whether the district court properly imposed a constructive trust,

we rely on Colorado state law given the location of the federal forum in which this

case originated. 11 See Foster v. Kinzler (In re Foster), 
275 F.3d 924
, 926 (10th Cir.

2001) (observing that we “look to state law to determine whether a party has met [its]

burden” of establishing a constructive trust); see also
 id. (applying Colorado state 
law

when the case arose in Colorado federal court). And under Colorado law, a

constructive trust is an “in personam order that requires . . . the constructive


      11
         In their briefing on this issue, both parties rely on Colorado state law and
neither party argues that the law of another jurisdiction controls.
                                                22
trustee . . . to transfer specific property in some form to . . . the beneficiary of the

trust.” In re Marriage of Allen, 
724 P.2d 651
, 657 (Colo. 1986) (emphasis in

original). But the monikers “constructive trustee” and “beneficiary of the

[constructive] trust” are a bit misleading.
 Id. Indeed, “in the 
modern law of

constructive trust there is no requirement that the parties have ever occupied a

fiduciary or confidential relation[ship]” that actual trusts require. Restatement

(Third) of Restitution and Unjust Enrichment § 55 cmt. B (2011). Still, we continue

to use the trust metaphor because “the central feature of the [constructive trust]

remedy” is “the determination by the court that B’s legal title to particular property

must yield to A’s superior (and equitable) right of ownership.”
 Id.

       But for our 
purposes today, the striking part of a constructive trust under

Colorado law involves its nature as an in personam order. In Latin, “in personam”

means “against a person.” In personam, Black’s Law Dictionary (11th ed. 2019). An

in personam order, therefore, means an order that binds “a person rather than

property.” United States v. Jantran, Inc., 
782 F.3d 1177
, 1180 n.2 (10th Cir. 2015)

(quoting In personam, Black’s Law Dictionary (9th ed. 2009)). And as applied to

this case, that means the constructive trust does not bind the real estate itself; instead,

it binds the owners of the real estate.

       Yet as we described above, most of the owners of the real estate are

nonparties. As the Supreme Court has made clear, “[i]t is a principle of general

application in Anglo-American jurisprudence that one is not bound by a judgment in

personam in a litigation in which he is not designated as a party or to which he has

                                                23
not been made a party by service of process.” Hansberry v. Lee, 
311 U.S. 32
, 40

(1940); see also Taylor v. Sturgell, 
553 U.S. 880
, 892–93 (2008) (quoting Richards v.

Jefferson Cnty., 
517 U.S. 793
, 798 (1996)) (“deep-rooted historic tradition” of due

process requires, at the bare minimum, “that everyone should have his own day in

court” and a nonparty “generally has not had a ‘full and fair opportunity to litigate’

the claims and issues settled in” the lawsuit). So because the entities that own the

real estate are nonparties, and because the district court’s order imposing a

constructive trust was an in personam order against them, the constructive trust

presumptively does not bind them.

       The district court believed that it had the authority to attach the constructive

trust to the real properties at issue “regardless of the title to the properties” because,

in its view, “the very function of a constructive trust is to pierce the ‘legal’ façade to

do equity under the circumstances.” In other words, the district court apparently

believed that a constructive trust can bind anybody who holds title to property so long

as the property rightly belongs to the person asking for the constructive trust.

       Although we agree that a constructive trust is a flexible remedy that a district

court may employ when justice so requires, that does not mean that a court can

automatically use a constructive trust to pierce the legal façade of a nonparty title

holder. In most cases, subject to some limited exceptions, that would extend the

principle too far. A constructive trust is not an all-powerful tool; it is a remedy like

any other that is subject to the traditional tenets of in personam orders. Thus, courts



                                                24
normally impose constructive trusts against parties in the litigation. The district

court thus erred in concluding otherwise. 12

      Because the district court misapplied the constructive trust remedy, we think

the most appropriate course is to remand this case to the district court for further

proceedings. As noted above, some limited exceptions permit constructive trusts to

bind nonparties. For example, the Supreme Court has said that courts may bind

nonparties when they have a “substantive legal relationship” with an actual party to

the suit, such as the relationship between “preceding and succeeding owners of

property.” 
Taylor, 553 U.S. at 894
. In a similar vein, the Supreme Court has

observed that courts may bind nonparties when they are “adequately represented by

someone with the same interests who [is] a party.”
 Id. (quoting D. Shapiro, 
Civil

Procedure: Preclusion in Civil Actions 78 (2001) and 
Richards, 517 U.S. at 798
).

Further, Colorado law recognizes “reverse piercing of the corporate veil,” which

“occurs when a [plaintiff] seeks to disregard the separate existence of a corporation

and obtain the assets of the entity due to the actions of a dominant shareholder or

other corporate insider. In re Phillips, 
139 P.3d 639
, 641 (Colo. 2006).

      Given these potential exceptions, the district court can decide in the first

instance whether these exceptions (or any others) do apply. This will allow the



      12
         On a related note, the fact that “a constructive trust can be imposed on a
third party into whose possession the property or its proceeds can be traced” does not
change our analysis. In re Marriage of 
Allen, 724 P.2d at 657
. “Third party” does
not necessarily mean “nonparty.”

                                               25
district court—the undisputed expert in the case who has overseen it for nearly a

decade—to pass judgment on the matter first because we are a court of review, not

first view. We therefore vacate the district court’s order imposing a constructive

trust to the extent that the trust binds any nonparties to this case, and we remand to

the district court for proceedings consistent with this framework.

                                            B.

       With all of that said, not all the owners of the real estate at issue are

nonparties. By our count, Tanya—either legitimately or through one of her own

aliases—owns three of the properties to which the district court attached the

constructive trust. Those properties apparently include one parcel of land at 1779

Cross Street in Innisfil, Ontario, and two parcels of land at 33 Theodore Place in

Vaughan, Ontario. We conclude that the district court abused its discretion by failing

to sufficiently trace the class’s swindled fees to those specific real properties.

       Although tracing in this case was (and is) a complicated endeavor, the district

court’s tracing analysis fell short of the required mark. The district court simply did

not provide enough analysis to satisfy us that attaching a constructive trust to these

three properties was not arbitrary. See Burke v. Regalado, 
935 F.3d 960
, 1011 (10th

Cir. 2019) (“A district court abuses its discretion when it renders an arbitrary,

capricious, whimsical, or manifestly unreasonable judgment.” (citation omitted)).

Indeed, the district court effectively asked us to trust it because “[i]t appears” the

swindled fees are traceable to those properties.



                                                 26
       We need more analysis to conduct meaningful appellate review. To that end,

we vacate the district court’s order attaching a constructive trust to the real estate that

Tanya owns. And we remand to the district court with instructions to conduct a

tracing analysis that explains in detail why a constructive trust should attach to each

of Tanya’s three properties in the specific amounts that the district court previously

identified (or, if the amounts differ from before, why that difference is justified). 13

                                            VI.

       In sum, we VACATE the district court’s order imposing a constructive trust to

the extent that the trust binds any nonparties to the case, and we remand to the

district court for proceedings consistent with section V(A). We also VACATE the

district court’s order attaching a constructive trust to the real estate that Tanya owns

(which is apparently one parcel of land at 1779 Cross Street in Innisfil, Ontario, and

two parcels of land at 33 Theodore Place in Vaughan, Ontario) and remand with

instructions to conduct a thorough tracing analysis. In all other aspects, we AFFIRM.




       13
         Of course, if the district court determines on remand that a constructive trust
should continue to bind the nonparty entities, it should likewise make sure to conduct
an equally in-depth tracing analysis as to those entities’ real properties.
