UConn School of Law professor Julia Simon-Kerr comments on a case that squarely presents the question whether the courtroom demeanor and body language of a non-testifying defendant can play a role in the jury’s consideration of guilt or innocence. Professor Simon-Kerr points out that despite research showing no evidence that we can learn much, if anything, about a person’s untruthfulness from nonverbal cues, jurors frequently rely on those factors in deciding the credibility of witnesses and, apparently, even the culpability of non-testifying defendants. She suggests that it although it is unlikely the Supreme Court will agree to hear the case, the case presents the Court with a unique opportunity to begin a long overdue reexamination of the privileged role of demeanor in our system of proof.
