United States v. Edward Bases

In the United States Court of Appeals For the Seventh Circuit ____________________ Nos. 23-1528 & 23-1530 UNITED STATES OF AMERICA, Plaintiff-Appellee, v. JOHN PACILIO and EDWARD BASES, Defendants-Appellants. ____________________ Appeals from the United States District Court for the Northern District of Illinois, Eastern Division. No. 1:18-cr-00048 — John Z. Lee, Judge. ____________________ ARGUED SEPTEMBER 7, 2023 — DECIDED OCTOBER 23, 2023 ____________________ Before BRENNAN, ST. EVE, and JACKSON-AKIWUMI, Circuit Judges. BRENNAN, Circuit Judge. John Pacilio and Edward Bases appeal their convictions for fraud through the manipulation of the precious metals market by “spoofing”—placing a de- ceptive order with no intent to trade to push the market in a certain direction. Defendants challenge their convictions on due process grounds, and they dispute several evidentiary 2 Nos. 23-1528 & 23-1530 rulings at trial. For the reasons set forth below, we affirm the district court’s judgments. I. Factual Background and Procedural History Pacilio and Bases were senior traders on the precious met- als trading desk at Bank of America Merrill Lynch (“Bank of America”), in New York. They conducted their trading on two commodities exchanges, COMEX and NYMEX, operated by the Chicago Mercantile Exchange (CME). While working to- gether at Bank of America from 2010 until 2011, and at times separately before and after that period, they engaged in a fraudulent scheme, known as spoofing, to manipulate the prices of precious metals. The mechanics of commodities futures trading make spoofing possible. A commodities futures contract is a stand- ardized agreement between a buyer and a seller to buy and sell a set amount of a specific commodity, at a set price, on a set, future date. Historically, the trading of commodities fu- tures through the CME occurred in person on the CME trad- ing floor. Since 2007, most CME trading takes place on the CME’s electronic trading platform, Globex, which allows traders to place buy or sell orders on certain numbers of fu- tures contracts at a set price. Traders place these orders man- ually or through programmed algorithms. Commodity prices are determined by supply and de- mand. Orders placed in the CME order book communicate buying and selling interest, affecting the market price for fu- tures contracts. The larger the order, the larger the effect on the commodity’s market price. Because larger orders can sig- nificantly impact the market, Globex permits traders to place “iceberg” orders, showing only a partial amount of the full Nos. 23-1528 & 23-1530 3 order. Traders on the COMEX and NYMEX exchanges may cancel an order before it is executed. But, it is assumed that every order placed is bona fide and placed with “intent to transact.” Spoofing schemes take advantage of this assump- tion by manipulating the market through the placement of large orders that are unintended to be executed. Spoofing con- sists of (1) placing an order, typically a large iceberg order, on one side of the market that is intended to be traded, and (2) placing a spoof order, fully visible but not intended to be traded, on the other side of the market. The spoof order pushes the market price to benefit the iceberg order, allowing the trader to execute the iceberg order at a desired price. The spoof order is then cancelled before it can be filled. On several occasions, each defendant placed an iceberg or- der to sell commodities contracts above the prevailing market price while simultaneously submitting visible spoof orders pushing the market price higher. Once the market price reached the level of the intended sale offer, the entire iceberg sell order was executed, and all the visible spoof orders were cancelled. Defendants also engaged in coordinated episodes, where one would place an iceberg buy order and the other would flood the market with spoof sell orders. The market price would plummet and enable filling the iceberg order at the desired price. Pacilio and Bases do not contest these facts. Rather, they challenge the constitutionality of their convictions, dispute the sufficiency of the evidence, and criticize the district court’s evidentiary rulings. A federal grand jury indicted Pacilio on one count of con- spiracy to commit wire fraud affecting a financial institution; seven counts of wire fraud affecting a financial institution; 4 Nos. 23-1528 & 23-1530 one count of commodities fraud; and one count of violating the anti-spoofing provision of the Dodd-Frank Act. The grand jury similarly indicted Bases on one count of conspiracy to commit wire fraud affecting a financial institution; nine counts of wire fraud affecting a financial institution; and one count of commodities fraud. Before trial, the government disclosed its plans to call CME representatives to testify that CME Rule 432 has always prohibited spoofing. Rule 432, in place since 1989, prohibits traders from attempting to engage or engaging in “the manip- ulation of prices of exchange futures or options contracts;” “any manipulative device, scheme, or artifice to defraud;” or offering to purchase or sell “exchange futures or options con- tracts, or any underlying commodities or securities, for the purpose of upsetting the equilibrium of the market or creating a condition in which prices do not or will not reflect fair mar- ket values.” This testimony, the government asserted, would support their implied misrepresentation theory. The defendants moved to preclude this testimony as irrel- evant and improper, arguing that CME representatives’ sub- jective interpretations of Rule 432, never disclosed to market participants, could neither form the foundation of an implied misrepresentation nor support a finding of intent to defraud. The district court denied the motion, concluding that Rule 432 was ambiguous as a matter of law as to whether it prohibited spoofing. Therefore, the government could offer extrinsic ev- idence from CME representatives interpreting the rule. At trial, the parties presented substantial evidence. Pursu- ant to the district court’s pre-trial ruling, the government called as witnesses two CME representatives, John Scheerer and Robert Sniegowski. Scheerer, a CME Senior Director, Nos. 23-1528 & 23-1530 5 testified that each order placed on the CME exchanges was expected to be a “bona fide order … placed with intent to transact.” Sniegowski, the longtime director of the CME’s Rules and Regulatory Outreach group, similarly testified the CME requires orders “be placed with the intent to buy” and sell—and Rule 432 prohibits spoofing. Sniegowski also out- lined the mechanics of spoofing and explained that a spoof order is a deceptive order placed with “no intent to trade” to “push the market in a particular direction.” The government also called an employee who worked with Pacilio and Bases, Harnaik Lakhan, as a cooperating wit- ness. Lakhan testified he engaged in spoofing and knew at the time it was “wrong.” He described how he, Pacilio, and Bases carried out the spoofing scheme by placing orders they in- tended to cancel for the sole purpose of “manipulat[ing] the price to the level you wanted it.” He admitted spoofing placed “false information” into the market both “as to demand, sup- ply,” and “intent” to trade, and stated defendants placed spoof orders “frequently” in the precious metals futures mar- kets. When cross-examined, Lakhan did not recall a CME rule prohibiting spoofing, was not familiar with Rule 432, and did not remember any pre-Dodd-Frank compliance training men- tioning spoofing. Additionally, the government presented testimony from bank officials concerning bank policies at the time of Pacilio’s and Bases’s conduct. These witnesses, John Juul and Ed McLaren, compliance officials with Deutsche Bank and Bank of America respectively, testified spoofing was always prohibited at their banks. The jury found Pacilio guilty of conspiracy to commit wire fraud affecting a financial institution, wire fraud affecting a financial institution, and commodities fraud, but not guilty of 6 Nos. 23-1528 & 23-1530 spoofing in violation of Dodd-Frank. The jury found Bases guilty of conspiracy to commit wire fraud affecting a financial institution and wire fraud affecting a financial institution, but not guilty of commodities fraud. The district court sentenced each defendant to 12 months and one day in prison. II. Discussion Defendants raise three challenges to their convictions. They assert the commodities and wire fraud statutes are un- constitutionally vague as applied to them in violation of the Fifth Amendment’s due process guarantee. They also challenge the sufficiency of the evidence supporting their con- victions for conspiracy to commit wire fraud and Pacilio’s conviction for commodities fraud. Finally, they argue the dis- trict court abused its discretion in admitting the testimony of the CME representatives and bank officials and excluding cer- tain evidence of Bases’s good faith. A. Due Process Challenge We review de novo both constitutional challenges to a con- viction and vagueness challenges. United States v. Coscia, 866 F.3d 782, 791 (7th Cir. 2017); United States v. Sandidge, 863 F.3d 755, 758 (7th Cir. 2017). The Fifth Amendment guarantees “[n]o person shall … be deprived of life, liberty, or property, without due process of law.” U.S. CONST. amend. V. This guarantee forbids vague criminal laws. Johnson v. United States, 576 U.S. 591, 595 (2015). To satisfy this guarantee, a criminal statute must “define the criminal offense (1) with suf- ficient definiteness that ordinary people can understand what conduct is prohibited and (2) in a manner that does not en- courage arbitrary and discriminatory enforcement.” Skilling v. Nos. 23-1528 & 23-1530 7 United States, 561 U.S. 358, 402–03 (2010) (quoting Kolender v. Lawson, 461 U.S. 352, 357 (1983)). “The void-for-vagueness doctrine prohibits the govern- ment from imposing sanctions under a criminal law so vague that it fails to give ordinary people fair notice of the conduct it punishes.” Welch v. United States, 578 U.S. 120, 124 (2016) (internal quotation marks omitted). “A vagueness challenge not premised on the First Amendment is evaluated as-ap- plied, rather than facially.” United States v. Calimlim, 538 F.3d 706, 710 (7th Cir. 2008). The “touchstone” of constitutional fair notice “is whether the statute, either standing alone or as con- strued, made it reasonably clear at the relevant time that the defendant’s conduct was criminal.” United States v. Lanier, 520 U.S. 259, 267 (1997). “[A] scienter requirement in a statute al- leviates vagueness concerns.” McFadden v. United States, 576 U.S. 186, 197 (2015) (internal marks omitted). Two statutory prohibitions are relevant. Title 18 U.S. Code § 1343 provides: Whoever, having devised or intending to devise any scheme or artifice to defraud, or for obtain- ing money or property by means of false or fraudulent pretenses, representations, or prom- ises, transmits or causes to be transmitted by means of wire, radio, or television communica- tion in interstate or foreign commerce, any writ- ings, signs, signals, pictures, or sounds for the purpose of executing such scheme or artifice … . The commodities fraud statute states: Whoever knowingly executes, or attempts to ex- ecute, a scheme or artifice—(1) to defraud any person in connection with any commodity for 8 Nos. 23-1528 & 23-1530 future delivery, or any option on a commodity for future delivery … ; or (2) to obtain, by means of false or fraudulent pretenses, representa- tions, or promises, any money or property in connection with the purchase or sale of any commodity for future delivery, or any option on a commodity for future delivery … . 18 U.S.C. § 1348. We have held twice—in Coscia and in United States v. Chanu, 40 F.4th 528 (7th Cir. 2022)—that spoofing violates the wire fraud and commodities fraud statutes. In Coscia, we con- sidered “whether spoofing amounts to a ‘scheme to defraud’” within the meaning of the commodities fraud statute. Chanu, 40 F.4th at 540 (citing Coscia, 866 F.3d 782). Coscia placed large spoof orders opposite small orders on CME exchanges in 2011 and used a preprogrammed algorithm to quickly cancel the spoof orders before they were filled. Coscia, 866 F.3d at 788-90. The government alleged Coscia placed the spoof orders “to create illusory supply and demand and, consequently, to in- duce artificial market movement.” Id. at 785. Coscia was con- victed of commodities fraud in violation of 18 U.S.C. § 1348(1), and spoofing, in violation of 7 U.S.C. § 6c(a)(5)(C). Id. Our court affirmed. Id. As to his commodities fraud con- viction, Coscia argued “because ‘his orders were fully execut- able and subject to legitimate market risk,’ they were not, as a matter of law, fraudulent.” Id. at 797. This court rejected that argument. Id. In Chanu, we again affirmed that spoofing was fraud, this time in a situation very similar to and involving the same scheme as the one Pacilio and Bases employed. Cedric Chanu and James Vorley were precious metals traders at Deutsche Nos. 23-1528 & 23-1530 9 Bank who traded futures contracts on the COMEX exchange using CME’s Globex platform. Chanu, 40 F.4th at 532. They “placed orders for precious metals futures contracts on one side of the market that, at the time the orders were placed, they intended to cancel prior to execution”—though unlike Coscia, Chanu and Vorley placed their trades manually. Id. at 533, 540. Chanu and Vorley were convicted on several counts of wire fraud. Id. at 538. On appeal we addressed whether the manual spoofing conduct violated the wire fraud statute and held it was determined by two questions: “Was there a scheme to defraud by means of false representations or omis- sions, and were such false representations or omissions mate- rial?” Id. at 539. “Coscia establishes that placing orders on opposite sides of the commodities market with the intent to cancel amounts to a ‘deceitful’ scheme, aiming to ‘manipulate the market for [the trader’s] own financial gain.’” Chanu, 40 F. 4th at 540 (quoting Coscia, 866 F.3d at 797). The Chanu defendants attempted to distinguish Coscia, ar- guing “[b]ecause they were engaged in manual trading, … their trades—unlike Coscia’s—were actually tradeable due to the length of time they remained active prior to cancellation.” Id. That reasoning was unpersuasive, and we affirmed the convictions in Chanu. In Coscia, we had “rejected Coscia’s de- fense that he ‘placed real orders that were exactly that, orders that were tradeable’—the same defense Chanu and Vorley now employ.” Id. (quoting Coscia, 866 F.3d at 790, 797 (cita- tions omitted)). Importantly, we noted “order placement signals a trader’s intent to buy or sell.” Id at 541. Thus, “[b]y obscuring their intent to cancel, through an orchestrated ap- proach, Chanu and Vorley advanced a quintessential ‘half- truth’ or implied misrepresentation—the public perception of an intent to trade and a private intent to cancel in the hopes of 10 Nos. 23-1528 & 23-1530 financial gain.” Id. Moreover, we emphasized so long as the trading conduct “is deceitful and aligns with the plain mean- ing of ‘scheme to defraud,’” it can be criminalized under the commodities fraud or wire fraud statute. Id. The defendants had fair notice that their conduct was pro- hibited by the wire and commodities fraud statutes. The fraud statutes have long been held to encompass “implied represen- tation[s]” and “misleading omission[s].” Chanu, 40 F.4th at 541. In particular, “[a] half truth, or what is usually the same thing as a misleading omission, is actionable as fraud … if it is intended to induce a false belief and resulting action to the advantage of the misleader and the disadvantage of the mis- led.” Emery v. Am. Gen. Fin., Inc., 71 F.3d 1343, 1348 (7th Cir. 1995). And, as we held in Chanu, the defendants’ spoofing conduct “advanced a quintessential ‘half-truth’ or implied misrepresentation” prohibited by the fraud statutes—namely the public perception of the intent to trade and the private in- tent to cancel. 40 F.4th at 541. Pacilio and Bases advance several arguments that the stat- utes are vague, but none are persuasive. First, defendants sub- mit it was not until “Coscia was indicted in October 2014, that the government first claimed that spoofing could be fraudu- lent.” Though “due process bars courts from applying a novel construction of a criminal statute to conduct that neither the statute nor any prior judicial decision has fairly disclosed to be within its scope,” courts may apply a statute to novel con- duct so long as the plain text permits. Lanier, 520 U.S. at 266. Years before Coscia, this court held that placing orders in the commodities market in a way that gives a “misleading sig- nal” can be an “active misrepresentation.” United States v. Dial, 757 F.2d 163, 169 (7th Cir. 1985). The Dial defendants Nos. 23-1528 & 23-1530 11 were found guilty of mail and wire fraud—in violation of 18 U.S.C. §§ 1341 and 1343—stemming from the trading of silver futures on the Chicago Board of Trade. Id. at 164. They had “defrauded the people from whom they bought silver futures contracts … by trading, without margin,” that is without cash backing, their clients’ accounts. Id. at 169. This court ulti- mately decided that though defendants “owed” no duty to disclose their unmargined trading “to people on the other side of their silver futures transactions, their trading an un- margined account was an active misrepresentation,” as trad- ing without margin indicates the trades are backed by cash when they are not, imbuing the trader with “powerful influ- ence on futures prices.” Id. Pacilio’s and Bases’s conduct is indistinguishable from that deemed illegal in other cases. By placing spoof orders they intended to cancel before execution, they sent misleading signals to the market that the demand for a given commodity was much higher, effecting an increase in the market price. Through this active misrepresentation of demand, defend- ants’ iceberg orders would accrue significant profits when executed. Any novelty in this prosecution is based on the par- ticulars of defendants’ spoofing scheme, not any originality in construing the relevant fraud statutes. As we explained in Coscia, spoofing is a relatively new phenomenon aided by the development of high frequency programmed trading. 866 F.3d at 786–87. And as we have held before in Coscia and Chanu, spoofing is synonymous with other behavior actiona- ble as fraud. Second, defendants assert the passage of the Dodd-Frank Act’s spoofing provisions signals that spoofing was not previ- ously considered fraud. Dodd-Frank included an amendment 12 Nos. 23-1528 & 23-1530 to “prohibited transactions” under the Commodity Exchange Act, 7 U.S.C. § 6c(a)(5)(C), recognizing spoofing as unlawful. But Congress did not create the concept of spoofing. As the Exchange Act notes, the term spoofing was “commonly known to the trade.” 7 U.S.C. § 6c(a)(5)(C). Moreover, “[t]he Federal Criminal Code is replete with provisions that crimi- nalize overlapping conduct.” Pasquantino v. United States, 544 U.S. 349, 359 n.4 (2005). As we have just noted, the wire and commodities fraud statutes criminalized defendants’ conduct before the passage of Dodd-Frank. Third, Pacilio and Bases contend the government’s de- scription of the spoofing scheme is impermissibly broad to capture their conduct. Yet in Coscia, we characterized a similar scheme—although it used an algorithm rather than manual trades—as market manipulation akin to “pump and dump” schemes that the government prosecutes under the mail and wire fraud statutes. 866 F.3d at 797. The government’s de- scription is therefore consonant with this court’s precedent. Fourth, defendants urge the court to rely on the Fifth Cir- cuit’s en banc decision in United States v. Radley, 632 F.3d 177 (5th Cir. 2011), to hold that it is not fraud to place trades with- out the intent to enter into a transaction if the trades are at risk of being executed. The Radley defendants were charged with a conspiracy to manipulate the price of propane “by placing multiple bids … in order to trick other market participants into believing that demand for the commodity was strong and came from more than one source” and “placed bids at prices higher than other bidders had posted, allegedly perpetrating their deception by enticing other market participants to trans- act at higher prices.” Id. at 180. The district court had previ- ously ruled that “even if [the bids] were higher than any Nos. 23-1528 & 23-1530 13 others, [they] were actually bids, and when they were ac- cepted, defendants actually went through with the transac- tions.” United States v. Radley, 659 F. Supp. 2d 803, 815 (S.D. Tex. Sep. 17, 2009). “Since defendants were willing and able to follow through on all of the bids, they were not mislead- ing.” Id. The Fifth Circuit affirmed the district court’s dismis- sal of the indictment’s price manipulation, cornering, and wire fraud counts. 632 F.3d at 179. This court previously addressed Radley in Coscia. 866 F.3d at 797 n.64. We ruled that Radley was not analogous because that case did not involve an attempt “to create the illusion of artificial market movement that included the use of large orders to inflate the price while also taking steps to avoid transactions in the large orders.” Id. That is the conduct (which Pacilio and Bases do not dispute) that occurred here, though through manual trades rather than a programmed al- gorithm. In Coscia and Chanu, this court specifically rejected this defense. Chanu, 40 F.4th at 540; Coscia, 866 F.3d at 790, 797. The defendants had sufficient notice that their spoofing scheme was prohibited by law. B. Sufficiency of the Evidence The defendants also challenge whether the evidence at trial supported their convictions. Because they moved for a judgment of acquittal, we review the sufficiency of the evi- dence in support of the conviction de novo. United States v. Durham, 766 F.3d 672, 678 (7th Cir. 2014). This court “con- strue[s] the evidence in the light most favorable to the gov- ernment, asking whether a rational trier of fact could have found the elements of the crime beyond a reasonable doubt.” United States v. Weimert, 819 F.3d 351, 354 (7th Cir. 2016). A conviction will be overturned “only if, after reviewing the 14 Nos. 23-1528 & 23-1530 record in this light, we determine that no rational trier of fact could have found the essential elements of the offense beyond a reasonable doubt.” United States v. Fitzpatrick, 32 F.4th 644, 649 (7th Cir. 2022) (internal quotation marks omitted). The burden to overturn a conviction on sufficiency of the evidence “is a high one,” one this court has “described as ‘nearly insur- mountable.’” Id. (quoting United States v. Anderson, 988 F.3d 420, 424 (7th Cir. 2021)). The government establishes a conspiracy by proving that “(1) two or more people agreed to commit an unlawful act, and (2) the defendant on trial knowingly and intentionally joined in the agreement.” See United States v. Griffin, 76 F.4th 724, 742 (7th Cir. 2023) (holding that sufficient evidence sup- ported two defendants’ convictions under 18 U.S.C. § 1349) (citation omitted). 1 Title 18 U.S.C. § 1343 criminalizes the use of wire, radio, or television communications to effect “any scheme or artifice to defraud, or for obtaining money or prop- erty by means of false or fraudulent pretenses … . To convict a defendant of wire fraud, the government must prove three elements: (1) the defendant participated in a scheme to de- fraud; (2) the defendant intended to defraud; and (3) a use of an interstate wire in furtherance of the fraudulent scheme.” United States v. Powell, 576 F.3d 482, 490 (7th Cir. 2009). The statute reaches “not only false statements of fact but also mis- leading half-truths and knowingly false promises.” Weimert, 819 F.3d at 355. Actionable misstatements can also “include 1 Though the fraud scheme in this case concerned commodities trad- ing—whereas the fraud in Griffin involved a scheme to fraudulently ob- tain Small Business Administration loans, 76 F.4th at 733–34—both cases dealt with allegations of wire fraud and conspiracy to commit such under 18 U.S.C. §§ 1343 and 1349. Nos. 23-1528 & 23-1530 15 the omission or concealment of material information, even ab- sent an affirmative duty to disclose, if the omission was in- tended to induce a false belief and action to the advantage of the schemer and the disadvantage of the victim.” Id. Clarify- ing the statutory term “scheme or artifice to defraud,” the Supreme Court has held that materiality of falsehood is an el- ement of the federal wire fraud statute. Neder v. United States, 527 U.S. 1, 25 (1999). 1. Sufficient evidence supports the defendants’ convictions for conspiracy to commit wire fraud. Lakhan testified how he, Pacilio, and Bases carried out the spoofing scheme by placing orders they intended to cancel for the sole purpose of “manipulat[ing] the price to the level you wanted it,” admitted that spoofing placed “false information” into the market “as to demand, supply,” and “intent” to trade, and stated defendants both placed spoof orders “frequently” in the precious metals futures market. The government also submitted evidence of numerous trades where defendants placed an iceberg order followed by a visible spoof order which was cancelled immediately after executing the iceberg order. The evidence further included contemporaneous chat messages between the defendants, Lakhan, and others dis- cussing their actions in placing “spoof” orders “not intended to be executed” in order to “push,” “move,” and “goose … up” the market price of commodities. The defendants do not contest any of this evidence. Ra- ther, they argue their wire fraud convictions should be re- versed because CME orders do not implicitly represent that a trader wants to trade. This argument is predicated on lan- guage in the operative third superseding indictment. That states the fraudulent orders placed by defendants were 16 Nos. 23-1528 & 23-1530 “material misrepresentations that falsely and fraudulently represented to market participants that [defendants] and oth- ers actually wanted to trade the Fraudulent Orders when, in fact, they did not want to do so.” To the defendants, because CME orders only impliedly represent that traders are willing to trade—not that they actually want to trade—the govern- ment did not prove the fraudulent misrepresentation in the indictment necessary for a wire fraud conviction. The terms “intend,” “intending,” and “intent” are used throughout the indictment, including in the crucial paragraph setting forth the elements for conspiracy to commit wire fraud. But in one instance in paragraph 12, the term “want” is used in the “Manner and Means” section of the conspiracy. The other sixteen paragraphs of that section do not use “want.” The jury was instructed that convictions for wire fraud re- quired that the defendants intended to not trade the spoof or- ders. In the instructions “scheme to defraud” meant “a scheme that is intended to deceive or cheat another and to ob- tain money or property or to cause the potential loss of money or property of another by means of materially false or fraud- ulent pretenses, representation, or promises.” (emphasis sup- plied) “[I]ntent to defraud” was defined as acting “knowingly with the intent to deceive or cheat in order to cause a gain of money or property to the defendant or another or the poten- tial loss of money or property to another.” The question for the jury was whether the defendants had fraudulent intent. The evidence was sufficient for a rational jury to find that in- tent beyond a reasonable doubt. Whether the trade orders showed a willingness or desire to trade does not matter. In Chanu, we held that placing an Nos. 23-1528 & 23-1530 17 order on the CME represented an intent to buy and sell. 40 F.4th at 540–42. In addition, the ubiquitous use of “intent” lan- guage throughout the indictment and the jury instructions cured any error created by the word “want” in one paragraph. One word in one paragraph of the 16-page indictment does not warrant reversal. 2. Sufficient evidence supports Pacilio’s conviction for commodities fraud. Pacilio also contends the government presented no evi- dence of his fraudulent intent in 2014 to substantiate his con- viction for commodities fraud. This challenge fares no better. Title 18 U.S.C. § 1348(1) criminalizes conduct “to defraud any person in connection with a commodity for future delivery.” To convict a defendant on commodities fraud, the govern- ment must prove (1) fraudulent intent, (2) a scheme or artifice to defraud, and (3) a nexus with a security. Coscia, 866 F.3d at 796 (citation omitted). “False representations or material omissions are not required” for a conviction under this stat- ute. Id. “Because [Pacilio] focuses on intent, this makes [the court’s] job relatively easy.” United States v. Johnson, 874 F.3d 990, 1000 (7th Cir. 2017) (internal quotation marks omitted). “[O]nce a jury has weighed the evidence and has found guilt beyond a reasonable doubt,” a challenge to the sufficiency of the evidence proving intent “is exceedingly difficult to win.” United States v. Dingle, 862 F.3d 607, 614 (7th Cir. 2017). The jury could find Pacilio intended to defraud based on the government’s data evidence depicting the spoofing scheme, Lakhan’s testimony, and prior evidence of Pacilio’s intent to commit wire fraud. Lakhan testified he witnessed Pacilio make the exact same types of spoofing trades at Mor- gan Stanley that he made at Bank of America during the time 18 Nos. 23-1528 & 23-1530 frame covered by the wired fraud convictions, where chats and emails provided clear evidence of Pacilio’s intent. Pacilio notes, and we agree, that Lakhan did not testify to Pacilio’s intent in the later time frame covering the commodities fraud. But direct evidence of intent is often unattainable, and “spe- cific intent to defraud may be established by circumstantial evidence and by inferences drawn from examining the scheme itself which demonstrate that the scheme was reason- ably calculated to deceive persons of ordinary prudence and comprehension.” United States v. Pust, 798 F.3d 597, 600–01 (7th Cir. 2015) (internal quotation marks omitted). Pacilio argues “[a] jury may not infer that because a de- fendant committed an illegal act once, he must have also com- mitted another alleged similar act.” For this he relies on United States v. Manganellis, 864 F.2d 528, 531 (7th Cir. 1988)). But un- like the prior intent evidence here, Manganellis concerned the admission of prior bad acts, id., so it is inapplicable. The gov- ernment’s prior intent evidence is not prior bad acts evidence. It is circumstantial evidence the jury could have relied upon to find that Pacilio maintained his fraudulent intent when continuing to trade in the exact same way at a later time pe- riod. We afford the district court great deference on this type of challenge. A reasonable jury could find beyond a reasonable doubt, based on all the prior evidence of Pacilio’s intent, cou- pled with the government’s data and Lakhan’s testimony, that Pacilio continued to trade at Morgan Stanley with the same fraudulent intent he possessed at Bank of America. Suf- ficient evidence supported Pacilio’s conviction for commodi- ties fraud. Nos. 23-1528 & 23-1530 19 C. The District Court’s Evidentiary Rulings Bases asks for a new trial, arguing the district court erred in (1) admitting testimony from CME representatives and bank officials, and (2) excluding evidence of his good faith. We review evidentiary rulings for an abuse of discretion. United States v. Pulliam, 973 F.3d 775, 782 (7th Cir. 2020). “Re- versal is warranted only where the reviewing court is left with the definite and firm conviction that a mistake has been com- mitted.” United States v. Daniel, 749 F.3d 608, 613 (7th Cir. 2014) (internal quotation marks omitted). An evidentiary er- ror requires reversal if the error was not “harmless.” United States v. Chaparro, 956 F.3d 462, 481–82 (7th Cir. 2020). “The general test for harmless error at trial is whether it is clear be- yond a reasonable doubt that a rational jury would have found the defendant guilty absent the error.” Id. at 482 (quot- ing United States v. Bonin, 932 F.3d 523, 538 (7th Cir. 2019)). 1. The district court properly admitted testimony of CME representatives and bank officials. Bases asserts the district court abused its discretion by ad- mitting testimony from CME representatives and bank offi- cials because their testimony was irrelevant and more preju- dicial than probative. This testimony was relevant. The district court admitted the testimony of CME representatives Robert Sniegowski and John Scheerer, who testified as lay persons to their under- standing of CME Rule 432 and its prohibition of defendants’ conduct. Sniegowski testified that Rule 432’s prohibition of “manipulation of prices,” “bad faith,” and “conduct … incon- sistent with just and equitable principles of trade” prohibited entering an order that the trader intends to cancel, i.e., 20 Nos. 23-1528 & 23-1530 spoofing. He also testified the CME requires traders to place only those orders that they “desire to actually buy or sell” and expects market participants to know the rules to ensure mar- ket integrity. Scheerer likewise testified CME rules prohibited traders from “placing orders with the intent to cancel before execution.” This testimony was relevant because defendants knew of the CME rules. Several commodities futures traders testified that they were on notice of and understood CME rules requir- ing that orders be bona fide and prohibiting the placement of orders with the intent to cancel them. The testimony was also relevant to demonstrate the defendants’ intent to manipulate the market by placing orders with the intent to cancel, con- trary to the expectation of market participants. The district court also admitted the testimony of John Juul and Ed McLaren, compliance officers at Deutsche Bank and Bank of America, respectively. They testified their financial institutions prohibit the placing of orders with intent to can- cel. The defendants contend this testimony is irrelevant be- cause “there was no evidence that anyone at the banks ever shared with [the defendants] that general prohibitions against ‘manipulation’ were interpreted or understood to encompass spoofing.” Both testified, though they worked in separate de- partments from defendants, that they functioned together as “one compliance department” and that traders at their banks were expected to understand and follow bank policies. Those included policies prohibiting market manipulation, such as spoofing. Further, the evidence showed that defendants knew of, and received training on, the banks’ compliance policies, much like they knew of and received training on the CME Rules. Nos. 23-1528 & 23-1530 21 The defendants submit this testimony’s probative value was outweighed by the danger of unfair prejudice, see FED. R. EVID. 403, because the testimony discussed market “manipu- lation,” which is a distinct offense not charged. “The balanc- ing of probative value and prejudice is a highly discretionary assessment, and [the court] accord[s] the district court’s deci- sion great deference, only disturbing it if no reasonable per- son could agree with the ruling.” United States v. Thomas, 321 F.3d 627, 630 (7th Cir. 2003). The defendants provide no rationale to reverse the district court’s decision. The govern- ment expressly defined for the jury what it meant by “manip- ulate.” Ladies and gentlemen, good morning. You have before you two bankers. These two bankers ma- nipulated the market prices of gold and silver. They pushed those prices up and they pushed those prices down with orders to buy and sell, orders that they knew sent fake signals to the market about supply and demand. The jury would not have confused “manipulate” with “mar- ket manipulation” because the terms are distinct. “Manipu- late” is a generally understood term distinct from a statutory term like “market manipulation.” The defendants were not convicted for manipulation, but for fraud. See United States v. Bloom, 846 F.3d 243, 252 (7th Cir. 2017) (holding sufficient evidence existed of defendants manipulating investment portfolio yield rates to support convictions for wire and in- vestment adviser fraud). And, as discussed previously, the district court sufficiently instructed the jury on the meaning of “scheme to defraud.” 22 Nos. 23-1528 & 23-1530 Bases relies heavily on United States v. Farinella, 558 F.3d 695 (7th Cir. 2009), in support of his claim of error in admit- ting this testimony. That case concerned whether sufficient evidence supported Farinella’s conviction for misbranding food with intent to defraud or mislead in violation of 21 U.S.C. §§ 331, 333. Id. at 697. The government presented the testimony of an FDA employee. Id. at 699. He testified he searched through an FDA database detailing inquiries re- garding the labeling of food products and found no record of inquiry from Farinella requesting a change to the “best when purchased by” date on their product. Id. “The implication was that changing the ‘best when purchased by’ date on a label requires the FDA’s permission, and he added that the FDA requires supporting data before approving a request to change the date.” Id. This court ruled the district court should not have admit- ted that testimony. Id. at 699–700. Most salient was the fact that, if such a requirement could predicate a criminal convic- tion, the requirement should be included “in some written interpretive guideline or opinion, and not just in the oral tes- timony of an agency employee.” Id. at 699. The court noted, “[i]t is a denial of due process of law to convict a person of a crime because he violated some bureaucrat’s secret under- standing of the law.” Id. That testimony discarded, the evi- dence was insufficient to support Farinella’s conviction. Id. at 700. Here, Bases asserts that, like in Farinella, the testimony from CME representatives and bank officials constitutes “some bureaucrat’s secret understanding of the law” and should have been prohibited. Id. at 699. But Farinella is easily distinguishable. There, to prove misbranding and fraud, the Nos. 23-1528 & 23-1530 23 government needed to establish that FDA approval was re- quired before changing a label. In contrast, Rule 432 was not a predicate for criminal liability here. Indeed, the district court instructed the jury, “[e]vidence that a defendant … violated an exchange rule or any bank policy is not sufficient, in and of itself, to find a defendant guilty of conspiracy to commit wire fraud, wire fraud, or commodities fraud.” The instruc- tion made clear the CME rule could not be the basis of crimi- nal liability and cured any potential confusion by the jury. Even if the testimony from the CME representatives and bank officials was erroneously admitted, such an error was harmless. This testimony went to the defendants’ state of mind: they intended to manipulate the market by placing spoof orders with the intent to cancel that traders would per- ceive as bona fide. Abundant evidence at trial supported a finding of fraudulent intent, including: defendants’ chat mes- sages; the testimony of Lakhan and others that CME rules prohibit traders from placing orders with the intent to cancel; and other witnesses’ testimony that spoof orders sent mis- leading signals to the market, irrespective of Rule 432 or bank policies. Admitting the testimony of the CME representatives and bank officials was not an abuse of discretion. 2. The district court correctly excluded evidence of Bases’s good faith. A key question at trial was whether Bases knew his con- duct was prohibited. He argues the exclusion of certain evidence of his good faith was an abuse of discretion. Specifi- cally, he faults the exclusion of certain chat messages between him and Bank of America colleague Simon Butler. Because the sequence of these messages is important to our analysis, a his- tory of their exchange is below. 24 Nos. 23-1528 & 23-1530 Bases and his colleagues received an email from their Bank of America supervisor, Rupen Tanna, on July 22, 2013, inform- ing them that the British regulatory authorities had fined Coscia and noting that his behavior is “deemed unaccepta- ble.” The following day, Bases and Butler engaged in the fol- lowing exchange: [Bases]: Did u read that thing that Rupen sent out? … [Bases]: Everyone has done it … [Bases]: Offered it or bid it to do the opposite [Bases]: The problem is [Bases]: Both orders were good [Butler]: it is however t[he] same as any algo based strategy [Bases]: U could have traded either side [Bases]: And that’s illegal? … [Bases]: They were real orders The government sought to exclude the evidence as hear- say that fell outside the scope of the state-of-mind exception under Federal Rule of Evidence 803(3). The district court agreed and excluded all the messages except for those bolded above. Exempt from the prohibition of hearsay are “statement[s] of the declarant’s then-existing state of mind … or emotional, Nos. 23-1528 & 23-1530 25 sensory, or physical condition …, but not including a state- ment of memory or belief to prove the fact remembered or believed unless it relates to the validity or terms of the declar- ant’s will.” FED. R. EVID. 803(3). Statements are admissible un- der the state-of-mind exception only when the following three requirements are met: “(1) the statement[s] must be contem- poraneous with the mental state sought to be proven; (2) it must be shown that declarant had no time to reflect, that is, no time to fabricate or misrepresent his thoughts; and (3) the declarant’s state of mind must be relevant to an issue in the case.” United States v. Neely, 980 F.2d 1074, 1083 (7th Cir. 1992). The district court properly excluded Bases’s statements. None of these messages were made contemporaneously with the execution of the orders they reference. Rather, Bases sent these messages to Butler the day after receiving the Rupen Tanna email, showing that Bases had ample time to reflect on the email and misrepresent his thoughts to Butler. Bases argues these statements were contemporaneous to his learning of the event to which he was reacting, namely the enforcement action against Coscia, and not prior trades. Even assuming the messages were not made in reference to prior trades, Bases still has a contemporaneity problem. He was not reaching out to Butler as the Tanna email came through. Cer- tainly, some of the statements are contemporaneous reactions to Butler’s questions. But other statements are likely thoughts Bases formulated following the arrival of the Tanna email the previous day. As such, Bases’s messages were properly ex- cluded as hearsay, and the district court did not abuse its dis- cretion. Even if the messages were improperly excluded, any error was harmless. The district court permitted Bases to introduce 26 Nos. 23-1528 & 23-1530 ample evidence addressing whether he had knowledge that his conduct was prohibited. This evidence included: Tanna’s email about Coscia; Bases’s reference to that email in the chat messages the next day; Bases’s contextual statement, “offered it or bid it to do the opposite;” and Bases’s questions, “And that’s illegal?” During closing argument, Bases’s counsel re- lied on this admitted evidence to argue Bases’s belief “that his trading was lawful.” As the government points out, Bases was able to introduce evidence on the very question he claims he was precluded from addressing. Therefore, the exclusion of other statements relevant to Bases’s good faith did not show beyond a reasonable doubt that a rational jury would have found the defendant guilty absent the error. The district court acted within its discretion. III. Conclusion For these reasons, we AFFIRM the judgments of the dis- trict court.
