Rule of Law:
A conviction under the federal drug conspiracy statute, 21 U.S.C. § 846, does not require the government to prove the commission of an overt act in furtherance of the conspiracy; the criminal agreement itself constitutes the completed offense.
Facts:
- Reshat Shabani participated in a narcotics distribution scheme in Anchorage, Alaska.
- Shabani's alleged role in the scheme was to supply the drugs.
- He arranged for cocaine to be smuggled into Alaska from California.
- Federal agents, working in an undercover capacity, purchased cocaine from distributors who were part of Shabani's conspiracy.
Procedural Posture:
- Reshat Shabani was charged with conspiracy to distribute cocaine in violation of 21 U.S.C. § 846 in the U.S. District Court for the District of Alaska.
- Shabani's motion to dismiss the indictment for failing to allege an overt act was denied by the trial court.
- The trial court also rejected Shabani's proposed jury instruction that would have required proof of an overt act for conviction.
- A jury returned a guilty verdict.
- Shabani, as appellant, appealed his conviction to the U.S. Court of Appeals for the Ninth Circuit.
- The Ninth Circuit, with the United States as appellee, reversed the conviction, holding that its precedent required proof of an overt act at trial.
- The United States petitioned the U.S. Supreme Court for a writ of certiorari, which was granted.

Issue:
Does the federal drug conspiracy statute, 21 U.S.C. § 846, require the government to prove that a defendant committed an overt act in furtherance of the conspiracy to obtain a conviction?
Opinions:
Majority - Justice O'Connor
No, the federal drug conspiracy statute, 21 U.S.C. § 846, does not require the government to prove the commission of an overt act in furtherance of the conspiracy. The plain language of the statute contains no such requirement. This silence is significant when contrasted with the general federal conspiracy statute, 18 U.S.C. § 371, which explicitly requires proof of an act 'to effect the object of the conspiracy.' Following precedents like Nash v. United States and Singer v. United States, the Court presumes Congress intended to adopt the common law definition of conspiracy, which holds that the agreement itself is the punishable act (the actus reus) and does not require a subsequent overt act. Therefore, the statute is not ambiguous, and the rule of lenity does not apply.
Analysis:
This decision resolved a circuit split, with the Ninth Circuit being the sole outlier, thereby creating a uniform national standard for drug conspiracy prosecutions. By holding that the agreement itself is the completed crime, the Court significantly lowers the evidentiary burden for the government in such cases. The ruling reinforces a key principle of statutory interpretation: when Congress includes specific language in one statute but omits it from another, the omission is presumed to be intentional. This decision makes it easier for prosecutors to secure convictions against members of drug trafficking organizations, as they only need to prove the existence of an illicit agreement rather than a specific subsequent action by a conspirator.
