Carpenter v. United States

(1) Whether the Double Jeopardy Clause entitles such a defendant to appellate review of his claim that the government failed to introduce legally sufficient evidence before he is subjected to the opprobrium, embarrassment, and toll of retrial on the same charges; (2) whether such a defendant is at least entitled to cross-appeal the district court"s denial of his motion for judgment of acquittal where the government takes an interlocutory appeal under 18 U.S.C. § 3731 from the district court"s grant of a new trial.
