The Tennessee Supreme Court has a reversed its previous position and determined that it will permit juries to hear evidence from qualified experts on the reliability of eyewitness identification. The Court had ruled that such testimony was not admissible in 2000.
Now, in State v. Copeland, the Court has reached a different result. After reviewing advances in the field over the last few years, the Court said:
"In our view, it is far more likely for the jury to accredit the eyewitness than the expert. If eyewitness identification is a cornerstone of the criminal justice system, the jury is its foundation. It is also our view that the test in McDaniel is sufficient to allow the trial court to properly evaluate the admissibility of expert testimony on the reliability of eyewitness identification. To the extent that Coley holds otherwise, it is overruled. The essential role of the judge, as the neutral arbiter in the trial, is to govern the admission of the evidence within the rules, permitting only that expert testimony which substantially assists the jury in its consideration of the issue. The McDaniel test provides the trial judge with the necessary guidelines to properly exercise his or her discretion."
