Rule of Law:
The "knowingly or intentionally" mens rea requirement of 21 U.S.C. §841 applies to the statute's "except as authorized" clause, meaning that once a defendant produces evidence of authorization, the Government must prove beyond a reasonable doubt that the defendant knowingly or intentionally acted in an unauthorized manner.
Facts:
- Petitioners Xiulu Ruan and Shakeel Kahn were medical doctors licensed to prescribe controlled substances.
- Both doctors were separately charged with violating 21 U.S.C. §841 for unlawfully dispensing and distributing controlled substances.
- A federal regulation specifies that a prescription is only authorized if it is "issued for a legitimate medical purpose by an individual practitioner acting in the usual course of his professional practice" (21 CFR §1306.04(a)).
- At their separate jury trials, Ruan and Kahn argued their dispensation of drugs was lawful and that they did not knowingly or intentionally deviate from the standard defining an authorized prescription.
- Ruan requested a jury instruction requiring the Government to prove he subjectively knew his prescriptions were outside his authority, but the District Court rejected this, instructing on an objective "good faith" standard based on "standard of medical practice generally recognized."
- Kahn's trial also featured disagreements over mens rea instructions; the District Court instructed the jury that "good faith" meant "an honest effort to prescribe for patients’ medical conditions in accordance with generally recognized and accepted standards of practice."
- Both Ruan and Kahn were convicted under §841 for prescribing in an unauthorized manner.
Procedural Posture:
- Xiulu Ruan and Shakeel Kahn were separately charged with violating 21 U.S.C. §841 in federal district courts.
- Both Ruan and Kahn were convicted by juries on the charges.
- The Eleventh Circuit Court of Appeals affirmed Ruan’s convictions, holding that a doctor’s subjective belief was not a complete defense and an objective standard applied.
- The Tenth Circuit Court of Appeals affirmed Kahn’s convictions, holding that the Government must prove a doctor either subjectively knew a prescription was illegitimate or issued one objectively outside professional practice.
- Both Ruan and Kahn filed petitions for certiorari to the United States Supreme Court.
- The Supreme Court granted certiorari and consolidated the two cases for review.

Issue:
Does the "knowingly or intentionally" mens rea requirement in 21 U.S.C. §841 apply to the statute's "except as authorized" clause, thereby requiring the government to prove a doctor knowingly or intentionally acted in an unauthorized manner when prescribing controlled substances?
Opinions:
Majority - Justice Breyer
Yes, the statute's "knowingly or intentionally" mens rea applies to the "except as authorized" clause, meaning the Government must prove beyond a reasonable doubt that the defendant knew or intended to act in an unauthorized manner. The Court emphasized that criminal law generally seeks to punish conscious wrongdoing, and a long-standing presumption requires a culpable mental state (scienter) for criminal offenses. This presumption applies with "equal or greater force" when a statute, like §841, contains a general scienter provision ("knowingly or intentionally"). Authorization plays a "crucial" role in distinguishing lawful, socially beneficial conduct by doctors from wrongful conduct. The regulatory language defining authorized prescriptions is "ambiguous" and "open to varying constructions," making it difficult to differentiate legitimate from illegitimate conduct and increasing the risk of "overdeterrence" (punishing acceptable conduct too close to the criminal line). The severe penalties associated with §841 (including life imprisonment) also counsel in favor of a strong scienter requirement. The Court reinforced its conclusion by citing analogous precedent such as Liparota, X-Citement Video, and Rehaif, where "knowingly" was held to modify statutory clauses critical to distinguishing wrongful from innocent acts, even if not immediately adjacent. The Court rejected the Government's argument that 21 U.S.C. §885 (which outlines burdens of pleading and production for exceptions) negates the application of scienter, explaining that §885 only shifts the burden of production to the defendant, not the burden of persuasion, regarding authorization. Once authorization is raised, the Government must prove lack of authorization beyond a reasonable doubt. The Court also dismissed the Government's proposed "objectively reasonable good-faith effort" standard, stating that §841 explicitly uses "knowingly or intentionally," not "good faith" or "reasonable," and that imposing an objective standard would improperly shift criminal liability from the defendant's mental state to that of a hypothetical reasonable doctor, a position previously rejected in Elonis v. United States. Finally, the Court acknowledged that while subjective knowledge is required, it can be proven through circumstantial evidence, and the objective criteria within the regulation (e.g., "legitimate medical purpose," "usual course of professional practice") can be relevant to a jury's assessment of a defendant's knowledge.
Concurring in the judgment - Justice Alito
Yes, but the authorization defense should turn on whether a physician acted in subjective good faith when prescribing drugs, not on whether they "knowingly or intentionally" acted outside their authority. Justice Alito criticized the majority for creating a "new hybrid" that mixes characteristics of an offense element with an affirmative defense. He argued that the "except as authorized" clause is clearly an affirmative defense, not an element of the crime, citing 21 U.S.C. §885 which relieves the Government of the burden to "negative any exemption or exception" in pleadings or trial and places the burden of "going forward with the evidence" on the defendant. Alito contended that the mens rea canon, which presumes a culpable mental state for offense elements, does not apply to affirmative defenses. Instead, he argued that the meaning of "in the course of professional practice" should be informed by the Harrison Narcotics Act, the CSA's predecessor, under which the Supreme Court previously held that a doctor acts "in the course of his professional practice" when prescribing "in good faith" (Linder v. United States). Therefore, he would hold that a doctor who acts in subjective good faith in believing a prescription is for a valid medical purpose and means is entitled to the authorization defense. Alito disagreed with the majority's conclusion that the Government must prove lack of authorization beyond a reasonable doubt, arguing that common law places both the burden of production and persuasion for affirmative defenses on the defendant, or at least the burden of persuasion by a "preponderance of the evidence."
Analysis:
This landmark decision significantly impacts the prosecution of medical professionals under the Controlled Substances Act, clarifying the high mens rea standard required for conviction. By mandating proof of subjective knowledge or intent regarding unauthorized conduct, the Supreme Court provides greater protection for doctors against criminal liability for honest errors, medical judgment disagreements, or interpretations of ambiguous regulations, thereby mitigating the risk of "overdeterrence." However, the ruling is not an absolute shield, as the Government can still prove knowledge through circumstantial evidence, leveraging objective criteria of medical practice to infer a defendant's intent. The decision underscores the Court's commitment to the presumption of scienter in criminal law, particularly for serious felonies where conduct can easily be mistaken for legitimate professional actions, balancing the need to punish conscious wrongdoing with the imperative to protect legitimate medical practice.
