During Villarreal’s trial, the judge directed him not to discuss the substance of his ongoing testimony with counsel during an overnight recess, while permitting consultation on other matters. The Supreme Court held that this qualified restriction did not violate the Sixth Amendment. A trial court may protect the integrity of unfinished testimony by temporarily preventing coaching or rehearsal about that testimony, so long as the defendant remains able to consult counsel about other trial-related subjects. The restriction was materially narrower than a complete bar on attorney-client communication. The judgment was affirmed.
