Rodriguez-Rivera v. United States

Issue: Whether the United States Sentencing Guidelines' definition of a "controlled substance offense" as one that includes "the offense of . . . conspiring . . . to commit such offenses" is limited to only those state and federal crimes that categorically overlap the generic definition of a conspiracy, requiring proof of both an overt act and an agreement, as two circuits have held, or whether it does not, as six circuits have held.
