Page 2 GR Vending MI, LLC, et al. _________________ OPINION _________________ NALBANDIAN, Circuit Judge. Hello Farms, a Michigan marijuana grower, entered a contract to supply marijuana to Defendants GR Vending and CURA MI. When GR Vending breached, Hello Farms sued. And a jury awarded Hello Farms $31.8 million. Defendants argue that because the contract was illegal under federal law, the district court erred by not granting them judgment as a matter of law on their illegality defense. When the parties contracted, federal law made the growth, distribution, and possession of marijuana a crime. Michigan, like many other states, made it a business. But despite the legalization of marijuana in Michigan, federal courts cannot enforce agreements to commit federal crimes. We reverse. I. A. Congress enacted the Controlled Substances Act (CSA) in 1970. See 21 U.S.C. § 801 et seq. The CSA categorizes controlled substances into five schedules, with Schedule I substances receiving that classification based on a determination that they have a high potential for abuse, no currently accepted medical use in the United States, and a lack of accepted safety for use under medical supervision. Id. § 812(b)(1). By contrast, substances in Schedule III, for instance, receive that classification because they have a currently accepted medical use and a lower risk for abuse and dependency. Id. § 812(b)(3). When enacted, the CSA classified marijuana as a Schedule I controlled substance, id. § 812(c), making it “contraband for any purpose,” Gonzales v. Raich, 545 U.S. 1, 27 (2005). And as contraband, trafficking marijuana is a felony: It’s unlawful to “knowingly or intentionally . . . manufacture, distribute, or dispense, or possess with intent to manufacture, distribute, or dispense” marijuana, except as authorized by the CSA (like for government- approved studies). 21 U.S.C. § 841(a); see Raich, 545 U.S. at 13. For an individual’s first  No. 25-1759 Hello Farms Licensing MI, LLC v. Page 3 GR Vending MI, LLC, et al. offense, prison terms range from up to five years for quantities less than 50 kilograms of marijuana, to ten years to life for quantities over 1,000 kilograms (or more than 1,000 marijuana plants). 21 U.S.C. § 841(b)(1)(A), (D). Fines for offenses involving less than 50 kilograms can reach up to $250,000 for an individual and $1 million for non-individual defendants. Id. § 841(b)(1)(D). Offenses involving over 1,000 kilograms can result in fines of up to $10 million for an individual, and $50 million for non-individual defendants. Id. § 841(b)(1)(A). And those figures aren’t ceilings: The CSA authorizes the greater of the listed amount or a fine allowed under Title 18, which may reach twice the gross gain or loss from the offense. Id.; see 18 U.S.C. § 3571(d). Simple possession and attempts or conspiracies to violate the CSA are crimes as well. 21 U.S.C. §§ 844(a), 846; see United States v. Shabani, 513 U.S. 10, 11 (1994) (holding that conspiracy under § 846 doesn’t have an overt-act requirement). But in 2014, Congress passed an appropriations rider known as the Rohrabacher-Farr Amendment (RFA). The RFA provided that “[n]one of the funds made available in this Act to the Department of Justice may be used, with respect to the [32 states and D.C.] . . . [including] Michigan . . . to prevent such States from implementing their own State laws that authorize the use, distribution, possession, or cultivation of medical marijuana.” Pub. L. No. 113-235, § 538, 128 Stat. 2130, 2217 (Dec. 16, 2014) (emphasis added). According to the circuits that have interpreted the RFA, the rider bars the DOJ from spending funds appropriated by the act to prosecute offenses involving state-legal medical marijuana where the underlying conduct complied with state law. See, e.g., United States v. McIntosh, 833 F.3d 1163, 1177 (9th Cir. 2016).1 1The Ninth Circuit in McIntosh was the first appellate court to address the RFA’s effect on federal prosecutions. It concluded that defendants may enjoin a marijuana prosecution “only if they ‘strictly compl[ied]’” with state medical-marijuana laws. United States v. Pisarski, 965 F.3d 738, 741 (9th Cir. 2020) (quoting McIntosh, 833 F.3d at 1178). That’s because the federal government “prevent[s] the state from giving practical effect” to its medical-marijuana laws with such prosecutions. McIntosh, 833 F.3d at 1176–77. And the First and Tenth Circuits have interpreted the RFA similarly, though they didn’t embrace the strict-compliance standard. United States v. Stacy, 156 F.4th 994, 1012 (10th Cir. 2025) (“[W]e conclude that the rider bars the prosecutions of private individuals who comply with state medical-marijuana laws.”); United States v. Bilodeau, 24 F.4th 705, 714–15 (1st Cir. 2022) (rejecting the strict-compliance approach but declining to define precisely the degree of compliance required). All three circuits placed the burden on defendants to prove their compliance with state law. See Stacy, 156 F.4th at 1014; United States v. Sirois, 119 F.4th 143, 152 (1st Cir. 2024); Pisarski, 965 F.3d at 742.  No. 25-1759 Hello Farms Licensing MI, LLC v. Page 4 GR Vending MI, LLC, et al. Until recently, that’s been the federal landscape. Each year since 2014, Congress has reenacted the RFA using substantially the same language. United States v. Trevino, 7 F.4th 414, 420 n.3 (6th Cir. 2021); see, e.g., Pub. L. No. 119-74, § 531, 140 Stat. 5, 57 (Jan. 23, 2026). And marijuana stayed a Schedule I substance—contraband for all purposes. But in April 2026, the landscape changed. While this appeal was pending, the U.S. Department of Justice issued a final rule rescheduling FDA-approved marijuana products and marijuana covered by a state medical license to Schedule III. See 91 Fed. Reg. 22714–23 (Apr. 28, 2026). Despite the rescheduling, state-licensed marijuana businesses must receive FDA approval before introducing marijuana products into interstate commerce, and they must register with the DEA to lawfully grow or distribute marijuana for medical use. See id. at 22719–20. Shifting to state law, Michigan, like other states, has charted its own path by legalizing marijuana for medical and recreational use. In 2008, it legalized certain medical uses of marijuana. See Mich. Comp. Laws §§ 333.26421–30. And by 2018, it had enacted a robust regulatory framework for the legal cultivation, distribution, and possession of marijuana for medical and adult recreational use. See generally id. §§ 333.27101–801, 333.27951–67. As part of its framework, Michigan requires regulated marijuana products to be tested for contaminants and tetrahydrocannabinol (THC), the main psychoactive compound in marijuana, regardless of the marijuana’s medical or recreational purpose. See, e.g., id. §§ 333.27505, 333.27958. Michigan also issues licenses authorizing the holder to grow and distribute marijuana within either the medical- or recreational-use markets. On the growing side, a medical grower’s license allows the licensee to cultivate marijuana and sell only to other licensed medical entities, like processors, other growers, or provisioning centers. Id. § 333.27501. And a recreational grower’s license allows the licensee to sell marijuana to businesses with recreational licenses. See id. § 333.27953(m). Both types of growing licenses come with limits on how many marijuana plants can be grown under a single license, so a business can acquire multiple licenses to increase its allowed yield. See id. §§ 333.27501(1), 333.27959(2). On the consumer-facing We, on the other hand, have yet to interpret the RFA’s effect on federal prosecutions. See United States v. Trevino, 7 F.4th 414, 422 (6th Cir. 2021) (assuming without deciding that the RFA “is as robust as the Ninth Circuit suggested in McIntosh”). And we have no occasion to do so here.  No. 25-1759 Hello Farms Licensing MI, LLC v. Page 5 GR Vending MI, LLC, et al. side, as one example, a provisioning-center medical licensee can sell only to registered qualifying patients or their caregivers. Id. § 333.27504. And a recreational-retailer license allows a business to sell marijuana for recreational use to consumers who are at least 21 years old. See id. § 333.27953(q). Finally, a business holding medical and recreational licenses of an equivalent type—for instance, a provisioning-center medical license and a recreational-retailer license—can transfer its product between its medical and recreational inventories. See id. § 333.27903; Mich. Admin. Code r. 420.214. B. With that backdrop in mind, we turn to the contract here. In November 2020, Defendants GR Vending and CURA MI, both subsidiaries of Curaleaf Holdings, Inc., entered an outputs contract for Hello Farms’s marijuana: GR Vending agreed to buy all the marijuana grown by Hello Farms in its 2020 and 2021 harvests. At that time, Hello Farms was licensed by Michigan to grow only medical marijuana. And GR Vending held Michigan licenses to operate as a provisioning center and retailer—in other words, to sell marijuana for medical and recreational use. CURA MI acted as GR Vending’s guarantor. The contract noted the parties’ expectation that Hello Farms would produce 12,000 to 15,000 pounds of marijuana (or 6,000 plants) in its 2020 harvest. GR Vending also agreed to pay Hello Farms $2.2 million as a deposit that was subject to refund under certain conditions. One such condition required Hello Farms’s marijuana to “pass[] local and state recreational cannabis testing requirements.” R.128-4, Agreement, PageID 6181 (emphasis added). Hello Farms agreed to test every 50-pound batch of marijuana for THC potency and contaminants, like heavy metals and pesticides. And whenever any 10 to 20 batches passed testing, Hello Farms would tell GR Vending, and GR Vending would buy that part of the harvest. If any 50-pound batch didn’t pass testing requirements, GR Vending could reject the batch or renegotiate the price. And if enough batches failed, GR Vending could end the contract. Hello Farms’s 2020 harvest yielded around 16,300 pounds of marijuana, all of which passed the contractually required testing. GR Vending paid the deposit and accepted the first shipment of around 2,000 pounds. But by January 2021, the price of marijuana was in freefall.  No. 25-1759 Hello Farms Licensing MI, LLC v. Page 6 GR Vending MI, LLC, et al. So GR Vending refused to accept any more deliveries from Hello Farms. In response, Hello Farms sold the rest of its 2020 harvest to a third party at lower prices. And for its 2021 harvest, it expanded its arable land from 7 to 25 acres and acquired recreational growing licenses. This enabled Hello Farms to produce around 37,500 pounds in 2021, which it sold to the same third party, again at lower prices than it would’ve received from GR Vending. C. In February 2021, Hello Farms sued Defendants for breach of contract in Michigan state court to recover lost profits from Defendants’ breach. Defendants removed to federal court based on diversity jurisdiction, asserted counterclaims, and raised an illegality defense based on the federal illegality of marijuana. After discovery, the parties cross-moved for summary judgment. The district court denied Defendants’ summary-judgment motion and rejected their illegality defense, and the case went to trial. The jury found Defendants liable for breaching the contract and awarded Hello Farms $31.8 million. Then Defendants renewed their motion for judgment as a matter of law and, alternatively, moved for a new trial. Again, Defendants argued that the district court couldn’t enforce the contract because marijuana is federally illegal. And again, though describing it as a close call, the court rejected that defense. It held the contract enforceable for two reasons: The contract was a medical-marijuana contract, and the RFA reflects a federal policy that tolerates medical-marijuana markets in states where they are legal. Defendants appeal the district court’s post-trial denial of their motions for judgment as a matter of law and a new trial. They raise three issues. First, they argue that Hello Farms can’t recover from the breach because marijuana is federally illegal. Second, they argue that, even if the contract is enforceable in part, the federal illegality of marijuana prevents Hello Farms from collecting damages that arise from its 2021 sale of recreational-use marijuana. And third, they argue that Hello Farms didn’t present enough evidence to justify the $31.8 million jury award. Because we agree with Defendants on the first issue, and because that issue resolves this appeal, we don’t address the other two issues.  No. 25-1759 Hello Farms Licensing MI, LLC v. Page 7 GR Vending MI, LLC, et al. II. Defendants argue that the district court erred by rejecting their illegality defense. In Defendants’ view, Hello Farms’s breach-of-contract claim fails as a matter of law because federal courts can’t enforce federally illegal agreements. We review de novo the district court’s denial of Defendants’ renewed Rule 50 motion for judgment as a matter of law. Balsley v. LFP, Inc., 691 F.3d 747, 757 (6th Cir. 2012). And though we generally apply state substantive law in diversity cases, “the effect of illegality under a federal statute is a matter of federal law, even in diversity actions in the federal courts after [Erie R.R. Co. v. Tompkins, 304 U.S. 64 (1938)].” Kelly v. Kosuga, 358 U.S. 516, 519 (1959) (citation omitted) (evaluating whether a violation of the Sherman Act made a contract unenforceable in a diversity case); see Sola Elec. Co. v. Jefferson Elec. Co., 317 U.S. 173, 176–77 (1942); Associated Press v. Taft-Ingalls Corp., 340 F.2d 753, 769 (6th Cir. 1965). “[A] federal court has a duty to determine whether a contract violates federal law before enforcing it.” Kaiser Steel Corp. v. Mullins, 455 U.S. 72, 83 (1982). This duty has a long pedigree. See, e.g., McMullen v. Hoffman, 174 U.S. 639, 669–70 (1899); Holman v. Johnson, 98 Eng. Rep. 1120, 1121 (K.B. 1775) (“No court will lend its aid to a man who founds his cause of action upon an immoral or an illegal act.”). And it exists because “[t]he power of the federal courts to enforce the terms of private agreements is at all times exercised subject to the restrictions and limitations of the public policy of the United States as manifested in federal statutes.” Kaiser Steel, 455 U.S. at 83–84 (citation modified). Though “the term ‘public policy’ is vague,” federal courts don’t ascertain federal policy from “general considerations of supposed public interests.” FDIC v. Aetna Cas. & Sur. Co., 903 F.2d 1073, 1077 (6th Cir. 1990) (quoting Muschany v. United States, 324 U.S. 49, 66 (1945)). Rather than engaging in a nose-in-the-air, freewheeling venture, we limit our inquiry to “explicit” and “well defined” federal policies announced by “laws and legal precedents.” Id. (quoting United Paperworkers Int’l Union v. Misco, Inc., 484 U.S. 29, 43 (1987)). So when enforcing a judgment in a breach-of-contract action “would itself be enforcing the precise conduct made unlawful” by explicit and well-defined federal law, Kelly, 358 U.S. at  No. 25-1759 Hello Farms Licensing MI, LLC v. Page 8 GR Vending MI, LLC, et al. 520, federal courts have “the obligation . . . to refrain from such exertions of judicial power,” Kaiser Steel, 455 U.S. at 84 (citation modified). And, specifically, when a party’s claim to damages is founded on an illegal agreement, we can’t permit recovery. See, e.g., id. at 77–79; Cont’l Wall Paper Co. v. Louis Voight & Sons Co., 212 U.S. 227, 262 (1909); McMullen, 174 U.S. at 669. We leave the parties as we find them. McMullen, 174 U.S. at 670. Because the reason that we won’t enforce these agreements is to avoid enforcing the precise conduct that is unlawful, we distinguish between cases where a party tries to enforce a legal agreement despite an illegal provision contained within the parties’ broader bargain, and cases where the agreement a party wants to enforce is itself illegal. Hemlock Semiconductor Operations, LLC v. SolarWorld Indus. Sachsen GmbH, 867 F.3d 692, 699 (6th Cir. 2017). In the former case, federal courts can enforce the legal agreement, at least where it’s “an intelligible economic transaction” separate from the individual promises tainted by illegality. Kelly, 358 U.S. at 521 (enforcing the defendant’s promise to purchase onions from the plaintiff even though the parties had also agreed to withhold onions from the market, likely a violation of the Sherman Act). And in the latter case, the agreement is unenforceable. See Kaiser Steel, 455 U.S. at 81– 82; Hemlock, 867 F.3d at 699. A. 1. To apply those principles here, we must first assess the bargain that Hello Farms seeks to enforce. In simple terms, Hello Farms promised to distribute all its marijuana to GR Vending. GR Vending promised to pay for it. And because GR Vending didn’t pay, Hello Farms took it to court. But the parties dispute how we should classify the marijuana, because whether the RFA— which applies only to medical marijuana—is a relevant federal policy depends on that classification. Hello Farms says that the contract was limited to medical-use marijuana; Defendants say that the contract included recreational-use marijuana. We agree with Defendants’ position. Nothing in the contract limited the transaction to the medical-marijuana market. In fact, the contract required that Hello Farms’s marijuana meet “local and state recreational cannabis testing requirements.” R.128-4, PageID 6181. This  No. 25-1759 Hello Farms Licensing MI, LLC v. Page 9 GR Vending MI, LLC, et al. requirement reveals that the parties didn’t limit their transaction to medical marijuana. And because GR Vending held medical and recreational licenses, under Michigan law it could introduce the marijuana it purchased from Hello Farms into the recreational market. See Mich. Admin. Code r. 420.214. So in other words, Hello Farms was supplying Michigan’s medical- and recreational-marijuana markets. Arguing that we should view the contract as limited to medical-use marijuana, Hello Farms relies on the fact that it held only medical growing licenses when entering the contract. So under Michigan law, Hello Farms could sell only to entities with medical licenses. See Mich. Comp. Laws § 333.27501. But this argument confuses the licensing needed to make the transaction legal under state law with the markets that GR Vending could legally serve under state law. And it ignores the fact that GR Vending held medical and recreational licenses. Michigan law allows a medical grower to sell to a buyer holding medical licenses alongside recreational ones, and it allows medical-to-recreational inventory transfers. See id. § 333.27903; Mich. Admin. Code r. 420.214. So Hello Farms’s possession of only medical licenses when entering the contract doesn’t mean the transaction was limited to the medical-marijuana market. What’s more, Hello Farms has no retort to the recreational-testing provision. In fact, it can’t point to any provision in the contract that could be read as limiting the transaction to the medical-marijuana market. Because the contract wasn’t limited to medical-use marijuana, the analysis is straightforward. The RFA and the April 2026 rescheduling apply only to medical marijuana, so they don’t influence our evaluation of federal policy here. See 91 Fed. Reg. 22714–15; e.g., Canna Provisions, Inc. v. Bondi, 138 F.4th 602, 608 (1st Cir. 2025). Federal policy against recreational marijuana, as reflected in the CSA, is explicit and well-defined. See Aetna Cas. & Sur. Co., 903 F.2d at 1077. On the face of the contract, the parties promised to commit felonies. See 21 U.S.C. § 841(b). Hello Farms’s cause of action seeks to enforce its claim to lost profits from the parties’ felonious agreement. Its claim isn’t founded on a legal agreement separate from an illegal one. See Kaiser Steel, 455 U.S. at 82. Nor is the illegality incidental to an otherwise legal agreement, like when “a party to a lawful contract . . . commits unlawful acts to  No. 25-1759 Hello Farms Licensing MI, LLC v. Page 10 GR Vending MI, LLC, et al. carry out his part of the bargain.” N. Ind. Pub. Serv. Co. v. Carbon Cnty. Coal Co., 799 F.2d 265, 273 (7th Cir. 1986). So ordering Defendants to pay Hello Farms would enforce the parties’ agreement to engage in “an illegal undertaking under the federal statutes.” Kaiser Steel, 455 U.S. at 79. That we cannot do. Id. at 77. 2. Hello Farms contends that whatever the scope of its contract, we wouldn’t be enforcing the precise conduct made illegal by the CSA because the transaction at issue “was an agreement merely to sell marijuana by Hello Farms to Defendants.” Appellee Br. at 55. So in Hello Farms’s view, the contract didn’t involve an agreement to violate the CSA. But this assertion ignores the obvious. The parties’ agreement was itself illegal. See 21 U.S.C. § 846.2 And that’s enough. We can continue, though. To perform the contract, Hello Farms had to possess the marijuana with the intent of distributing it to GR Vending—a crime. See id. § 841(a)(1). It then had to distribute the marijuana to GR Vending—another crime. See id. And GR Vending would then possess the marijuana with the intent of distributing it or dispensing it to consumers—yet another crime. See id. § 802(10)–(11) (defining “distribute” and “dispense”). Simply put, the agreement was founded on each party’s promise to commit crimes. Enforcing the agreement would enforce the precise conduct that the CSA criminalized. See Kaiser Steel, 455 U.S. at 77, 84. 2Hello Farms contends that, under United States v. Wheat, 988 F.3d 299 (6th Cir. 2021), a buyer-seller agreement doesn’t establish a drug-distribution conspiracy under 21 U.S.C. § 846. See id. at 304. But that’s too broad of a statement. Wheat, which involved a defendant giving a prospective buyer a free .3-gram sample of heroin, rejected turning every exchange of drugs for the buyer’s personal use into a drug-distribution conspiracy. Id. at 304, 307. But “if a buyer makes repeated purchases of large quantities of drugs from a seller, . . . these purchases allow a jury to conclude that the buyer and seller have reached a tacit agreement for the buyer to resell the drugs to downstream customers.” Id. at 308 (citation modified). GR Vending didn’t purchase Hello Farms’s marijuana for personal use. And GR Vending agreed to repeated purchases of 500 to 1,000 pounds of marijuana. Even so, concluding that the parties violated § 846 isn’t necessary to our holding. Without § 846, enforcing Hello Farms’s claim for damages would still be enforcing the parties’ agreement to violate § 841, even if they didn’t share the same criminal objective.  No. 25-1759 Hello Farms Licensing MI, LLC v. Page 11 GR Vending MI, LLC, et al. Nor do we accept Hello Farms’s suggestion that we can enforce its claim to lost profits because we wouldn’t be commanding any party to violate the law—we’d just be transferring money. Some courts have proposed this as well. See Bartch v. Barch, 111 F.4th 1043, 1063 n.23 (10th Cir. 2024); Polk v. Gontmakher, 2019 WL 4058970, at *2 (W.D. Wash. Aug. 28, 2019) (citing Bassidji v. Goe, 413 F.3d 928 (9th Cir. 2005)). But the “long established” rule is that “a court will not lend its aid, in any way, to a party seeking to realize the fruits” of an illegal agreement. Cont’l Wall Paper Co., 212 U.S. at 262; see also Associated Press, 340 F.2d at 759 (“A party to an illegal bargain cannot recover damages for breach thereof.” (citation modified)). The illegality defense isn’t limited to cases where the plaintiff seeks a judgment that commands an unlawful act.3 We must not enforce illegal conduct, not just refrain from commanding illegal conduct. We look to the agreement the plaintiff wants to enforce: GR Vending was obligated to pay Hello Farms only if Hello Farms fulfilled its obligation to give GR Vending marijuana. So by enforcing Hello Farms’s claim to lost profits, we’d be enforcing the performance Hello Farms expected to be paid for—distributing an illegal drug. And if the shoe were on the other foot, the result would be the same. If Hello Farms had breached its promise to distribute marijuana to GR 3Both Kaiser Steel and Continental Wall Paper, for example, are premised on this unsurprising proposition—that a transfer of money, which might be innocuous in and of itself, can be tainted by illegality. Federal courts can’t award lost profits from an illicit deal gone wrong just because transferring money is, by itself, not illegal. In Kaiser Steel, the plaintiff sued the defendant to enforce the latter’s promise to contribute to a union welfare fund. 455 U.S. at 76. Though the defendant’s contribution to the fund would, by itself, be legal, the Supreme Court held that it couldn’t enforce the agreement (assuming it was illegal) by ordering the defendant to contribute because the defendant’s promise “arose from and was measured by” the illegal agreement to penalize the defendant for doing business with certain employers. Id. at 78–79. And nowhere does Kaiser Steel suggest that the result would be different if the plaintiffs had crafted their request for relief as damages rather than specific performance. Continental Wall Paper rests on the same logic. The plaintiff’s sale of wallpaper to the defendant was itself lawful, and it had been completed. Cont’l Wall Paper Co., 212 U.S. at 252–53. Yet the Supreme Court refused to enter judgment for the unpaid balance because giving judgment for the excessive, combination-fixed purchase price would enforce the fixed prices, which is what the Sherman Act forbade. Id. at 266–67. Hello Farms’s claim to lost profits arises from and is measured by GR Vending’s promise to purchase an illegal drug. Crafting a distinction between GR Vending’s illegal promise to pay and a (supposedly innocuous) judgment ordering GR Vending to pay now is untenable. See Kaiser Steel, 455 U.S. at 81 n.6 (“[I]f a promise is illegal at its inception and cannot be enforced during the term of the contract, it does not spring to life and become enforceable when the contract expires . . . . The suit is still a suit on a presumptively illegal undertaking.”).  No. 25-1759 Hello Farms Licensing MI, LLC v. Page 12 GR Vending MI, LLC, et al. Vending and GR Vending sued for monetary damages, Hello Farms’s illegality defense would succeed.4 And finally, Hello Farms relies on Kelly, noting the “overriding general policy” of enforcing contracts to “prevent[] people from getting other people’s property for nothing when they purport to be buying it.” Kelly, 358 U.S. at 520–21 (quoting Cont’l Wall Paper, 212 U.S. at 271 (Holmes, J., dissenting)). It is, of course, the general policy of federal courts to enforce contracts, and we don’t invalidate them lightly. See Muschany, 324 U.S. at 66. That’s why Kelly enforced the “lawful sale” of onions. Kelly, 358 U.S. at 521 (emphasis added). And that’s why we refrain from enforcing contracts only in special circumstances—when enforcing the agreement would enforce the precise conduct made unlawful by explicit and well-defined federal policy.5 See Kaiser Steel, 455 U.S. at 80; Aetna Cas. & Sur. Co., 903 F.2d at 1077. But those are the circumstances we’re presented with here. And unlike the plaintiff in Kelly, Hello Farms isn’t trying to enforce a separable, legal agreement. See Kaiser Steel, 455 U.S. at 81–82; Hemlock, 867 F.3d at 699. B. In the alternative, even if we interpreted the contract as limited to medical-use marijuana, we would still reverse the district court. But that interpretation, according to Hello Farms, would implicate the RFA, which Hello Farms says changed federal marijuana policy. Hello Farms urges us to apply the balancing test for enforcing unlawful contracts that we used in Jackson Purchase, as the district court did. See Jackson Purchase Rural Elec. Co-op. Ass’n v. Loc. 4In fact, we would have the duty to refrain from enforcing the agreement, even if the defendant didn’t raise the defense. See, e.g., Kaiser Steel, 455 U.S. at 77 (“The authorities from the earliest time to the present unanimously hold that no court will lend its assistance in any way towards carrying out the terms of an illegal contract.” (citation modified)); Coppell v. Hall, 74 U.S. 542, 558 (1868) (“Whenever the illegality appears, whether the evidence comes from one side or the other, the disclosure is fatal to the case. No consent of the defendant can neutralize its effect.”); Apical Biotek, LLC v. Maitri Holdings, LLC, 2026 WL 177927, at *1–2 (3d Cir. Jan. 22, 2026). 5Hesitancy in applying the general principles of the federal illegality defense has been most often expressed when the defense is based on antitrust law. We’ve recognized that “illegality defenses based on antitrust law are disfavored” where the “contract was legal on its face” and where “complex[]” and “speculative” proof external to the agreement would be required to prove illegality. Hemlock, 867 F.3d at 701. But no such circumstances are present here. And even if we extended this disfavor beyond antitrust law, the contract here was illegal on its face.  No. 25-1759 Hello Farms Licensing MI, LLC v. Page 13 GR Vending MI, LLC, et al. Union 816, 646 F.2d 264, 267 (6th Cir. 1981). In Hello Farms’s view, if we apply Jackson Purchase balancing, the result is to enforce the contract. But we’re skeptical that Supreme Court precedent permits Jackson Purchase balancing. And even if Jackson Purchase balancing survives, at least for some circumstances, on that decision’s own terms it would’ve held this contract unenforceable without applying a balancing test. 1. In Jackson Purchase, we considered whether to enforce an implied agreement between a union and an employer for the employer to deduct dues and pay them to the union without written employee authorizations. 646 F.2d at 266. Section 302 of the Labor Management Relations Act declared this practice unlawful but prescribed a criminal penalty only for willful violations, making them misdemeanors. Id. The union argued that the agreement was enforceable. Id. But, even though neither party willfully violated Section 302, we held that the agreement was unenforceable. Id. at 267–68. To reach this result, we noted that though Section 302 didn’t criminalize the parties’ agreement because they didn’t act willfully, the lack of a criminal penalty didn’t render their unwitting violation lawful. Id. at 266. Their agreement was still unlawful, just not criminal. Id. at 267. And we recognized “a strong presumption that agreements in violation of a statute will not be sanctioned by the courts.” Id. We found the presumption to be “stronger than usual” because “Congress not only made the act of unauthorized checking off of union dues illegal, it also made the agreement to do that act illegal.” Id. At the same time, we said that not “all unlawful agreements are ipso facto void”—“[i]f the denial of relief is disproportionately inequitable the right to recover will not be denied.” Id. So to determine whether to enforce the agreement, we adopted the multi-factor balancing test from the Restatement of Contracts. Id. at 267; see Restatement (Second) of Contracts § 178 (A.L.I. 1981). Among other factors, the Restatement test tells courts to consider “the justified expectations of the parties,” “the forfeiture that would result from non-enforcement of the agreement,” and “the likelihood that refusal to enforce will further” the public policy that the agreement violates. Jackson Purchase, 646 F.2d at 267. Considering these factors and the  No. 25-1759 Hello Farms Licensing MI, LLC v. Page 14 GR Vending MI, LLC, et al. others, we declined to enforce the agreement even though its unlawfulness “was not serious.” Id. at 268. Notably, the union was “trying to enforce the illegal agreement itself,” and “one who has himself participated in an illegal act cannot be permitted to assert in a court of justice any right founded upon or growing out of the illegal transaction.” Id. at 267. To begin with, we doubt that Jackson Purchase’s balancing test survived Kaiser Steel. There, the Supreme Court reaffirmed that federal courts decline to enforce illegal contracts “not for the benefit of the defendant, but because public policy demands that it should be denied without regard to the interests of individual parties.” Kaiser Steel, 455 U.S. at 77–78 (quoting Cont’l Wall Paper, 212 U.S. at 262). Yet Jackson Purchase balancing gives weight to the parties’ interests by considering their expectation that courts would enforce the contract and the forfeiture that would result from non-enforcement, and it assesses the harmlessness of enforcing the contract. Jackson Purchase, 646 F.2d at 267. In principle, such balancing raises the prospect of enforcing the precise conduct made unlawful. The Supreme Court hasn’t adopted a Restatement-style balancing test or gestured toward equitable balancing to determine enforceability of a contract. It hasn’t considered the parties’ interests or the harmlessness of enforcing the contract in a particular instance. See Kaiser Steel, 455 U.S. at 77; Weil v. Neary, 278 U.S. 160, 173–74 (1929) (“Enforcement of such contracts, when actual evil does not follow, would destroy the safeguards of the law and lessen the prevention of abuses.”); McMullen, 174 U.S. at 669–70. Rather than balancing factors, it adopted a categorical rule: If “the judgment of the Court would itself be enforcing the precise conduct made unlawful,” the court can’t enforce the contract.6 Kaiser Steel, 455 U.S. at 80 (quoting Kelly, 358 U.S. at 520–21). And the Supreme Court necessarily rejected the D.C. Circuit’s reasoning—echoed in Jackson Purchase—that “considerations of equity and relative fault” might allow a federal court to enforce a contract that is illegal under federal law. Mullins v. Kaiser Steel Corp., 642 F.2d 1302, 1311 (D.C. Cir. 1980) (citation modified), rev’d 455 U.S. 72. Solidifying our view that Jackson Purchase was aberrant, Hello Farms hasn’t pointed us to, 6Consider the “justified expectations of the parties” factor. In cases where federal illegality isn’t clear or well-defined, rather than inquiring into the parties’ expectations about the contract’s legality (and, downstream from that, whether a court would enforce it) and balancing that with other factors, we could enforce the contract because it doesn’t violate an explicit and well-defined federal policy. See Aetna Cas. & Sur. Co., 903 F.2d at 1077–78.  No. 25-1759 Hello Farms Licensing MI, LLC v. Page 15 GR Vending MI, LLC, et al. nor have we found, any case where we’ve applied Jackson Purchase balancing. See, e.g., Hemlock, 867 F.3d at 700–02 (addressing a federal illegality defense without mentioning Jackson Purchase); Anderson v. Int’l Union, United Plant Guard Workers of Am., 370 F.3d 542, 554–55 (6th Cir. 2004) (same); Aetna Cas. & Sur. Co., 903 F.2d at 1077–79 (same). 2. But we don’t need to definitively condemn Jackson Purchase balancing as contrary to Supreme Court precedent. That’s because the conditions in which we applied the balancing test in Jackson Purchase aren’t present here. The agreement in Jackson Purchase was unlawful but not criminal. 646 F.2d at 266–67. And if it had been criminal, it would’ve been only a misdemeanor. Id. at 266. Only after noting those circumstances did we apply the balancing test. Though we said th
