Erik Charles Maund, aka Erik Moore v. United States

Where a jury has been exposed to extra-record information—here, information presented with the court’s apparent imprimatur, without the court’s or parties’ knowledge, and without any opportunity for a curative instruction or cross-examination—is a criminal defendant entitled to a new trial upon a showing that the extraneous information influenced the jury’s deliberations to his detriment, or must a court also consider whether the outcome would have been different but for the extraneous information?
