Gonzales v. Oregon
The Supreme Court ruled that the U.S. Attorney General could not use the Controlled Substances Act to block Oregon doctors from prescribing lethal doses of medication to terminally ill patients under the state's Death With Dignity law.
The decision limits how far federal drug regulators can reach into decisions about what counts as legitimate medical practice, leaving states significant room to set their own rules for physician-assisted suicide.
How it got here: A federal trial court permanently blocked the Attorney General's rule; the Ninth Circuit affirmed; the government asked the Supreme Court to review that ruling.
The Case in Depth
What happened
Oregon voters passed the Death With Dignity Act, letting state-licensed doctors prescribe lethal doses of drugs to terminally ill, consenting patients under strict safeguards. The prescribed drugs are also regulated by the federal Controlled Substances Act. In 2001, the U.S. Attorney General issued a rule declaring that using these drugs to assist suicide was not a "legitimate medical purpose," making such prescriptions a federal violation regardless of Oregon's law.
The question before the Court
Could the U.S. Attorney General use the federal drug law to stop Oregon doctors from prescribing lethal medication under the state's assisted-suicide law?
The Court's answer
No — the Court ruled that the Controlled Substances Act does not give the Attorney General power to declare physician-assisted suicide illegitimate and thereby block Oregon doctors from prescribing lethal medication under the state's law. Congress gave the Attorney General only narrow, specific powers over drug scheduling and physician registration, not a general power to define what counts as legitimate medical practice nationwide.
Because that specific authority was never delegated, the Attorney General's 2001 rule was not entitled to the strong deference courts normally give properly authorized agency actions. Judged instead on its own persuasive merits, the rule failed, since the statute's structure shows Congress meant to fight drug trafficking and addiction, not to override state medical-practice judgments like Oregon's.

Why it matters
Terminally ill Oregon patients who qualify under state law can keep getting prescriptions from their doctors, and those doctors do not risk losing their federal registration to dispense controlled substances for doing so. The ruling also curbs how much power a U.S. Attorney General can claim over medical-practice questions without clear authorization from Congress, shaping future clashes between federal drug enforcement and state health laws.
What changes now
The judgment affirming the injunction against the Interpretive Rule stands, so Oregon physicians can continue prescribing under the Death With Dignity Act without fear of federal deregistration for that reason alone. This is a final merits decision resolving the statutory question, though it leaves open whether Congress could pass new legislation explicitly giving the Attorney General authority over the issue.
What this does not decide
The Court did not decide whether the Constitution protects a right to assisted suicide, or whether Congress could pass a new law explicitly authorizing the Attorney General to regulate it. It also left open how much deference the Attorney General's interpretations might receive on matters closer to preventing conventional illicit drug trafficking.
Concurrences and dissents
Dissent — Justice Scalia
Justice Scalia argued there were three independent grounds to reverse: the Attorney General's rule deserved deference as an interpretation of his own regulation under Auer, it was in any case the most natural reading of that regulation, and it was independently valid as a Chevron-deferred interpretation of the statute's 'public interest' and 'public health and safety' factors. He argued the majority wrongly manufactured a 'parroting regulation' exception to Auer and misread the term 'control.'
Dissent — Justice Thomas
Justice Thomas argued the majority's narrow reading of the Controlled Substances Act was inconsistent with the broad reading the same Court had given the statute just months earlier in Gonzales v. Raich to uphold federal power over medical marijuana. He contended the majority selectively invoked federalism concerns here that it had rejected in Raich, calling the shift 'perplexing.'
How the Court got there
The legal reasoning, step by step
- The Court first asked whether the Attorney General's rule deserved special deference because it interpreted his own regulation, a principle from Auer v. Robbins. It found the regulation itself just restated the statute's own words, so the agency was not truly interpreting its own creation and this deference did not apply.
- The Court then considered whether the rule deserved Chevron deference, the broad deference courts give when Congress has clearly handed an agency power to make binding rules on a subject. That deference applies only if Congress actually delegated that specific rulemaking authority.
- Examining the statute's text, the Court found Congress gave the Attorney General only narrow powers: to schedule drugs through a detailed technical process, and to register or deregister individual physicians using a five-factor public-interest test. Declaring an entire category of medical practice illegitimate fit neither grant.
- The Court reasoned that Congress had placed medical judgments in the hands of the Secretary of Health and Human Services throughout the statute, and that the law's savings clause preserved state authority over medical practice absent a direct conflict, signals inconsistent with an implicit grant of broad power to the Attorney General.
- Because Congress had not clearly delegated authority to declare physician-assisted suicide illegitimate, the rule was not entitled to controlling deference, so its interpretation had to stand on its own persuasive force under the weaker Skidmore standard. The Court found it unpersuasive given the statute's focus on conventional drug trafficking and addiction rather than general medical policy.
Doctrinal impact
Cases affected by this decision
Distinguishes Auer v. Robbins (519 U. S. 452)
The Court said Auer's deference rule did not apply because the regulation here merely restated the statute.
Distinguishes Chevron U. S. A. Inc. v. Natural Resources Defense Council, Inc. (467 U. S. 837)
The Court applied Chevron's framework but found no delegation of authority, so deference was unwarranted.
Reaffirms Skidmore v. Swift & Co. (323 U. S. 134)
The Court relied on Skidmore's weaker persuasiveness standard to evaluate and ultimately reject the rule.
