Holding: Under the Double Jeopardy Clause, a criminal defendant can be subjected to a new trial if the jury in his original trial was deadlocked and could not reach a unanimous verdict. In this case, a state court ordered a new trial after finding an initial jury deadlocked, and in the second trial, the defendant was convicted. A federal court overturned the conviction after concluding that the trial court did not try hard enough to get the first jury to reach a unanimous verdict. The Supreme Court reversed, holding that the federal court did not give enough deference to the state trial courtâ€™s judgment about whether the first jury was truly deadlocked.
Judgment: Reversed and Remanded, 6-3, in an opinion by Chief Justice John Roberts on May 3, 2010. Justice Stevens dissented, joined by Justice Sotomayor and in part by Justice Breyer.
