Supreme Court of the United States January 21, 2003, 01-1184 (United States v. Jimenez Recio)

*272Justice Breyer

delivered the opinion of the Court.

We here consider the validity of a Ninth Circuit rule that a conspiracy ends automatically when the object of the conspiracy becomes impossible to achieve — when, for example, the Government frustrates a drug conspiracy’s objective by seizing the drugs that its members have agreed to distribute.
