In Calvin Smith, et al . v. United States, No. 11-8976, the Supreme Court of the United States will hear the following issue:
Whether withdrawing from a conspiracy prior to the statute of limitations period negates an element of a conspiracy charge such that, once a defendant meets his burden of production that he did so withdraw, the burden of persuasion rests with the government to prove beyond a reasonable doubt that he was a member of the conspiracy during the relevant period — a fundamental due process question that is the subject of a well-developed federal circuit split.
