People v. Branch, 28 N.Y.3d 1159 (2017)
The decision to admit or exclude expert testimony on factors affecting the reliability of eyewitness identification rests within the sound discretion of the trial court, which must balance the probative value of the evidence against its prejudicial or harmful effects.

The Court emphasized the balancing test between probative value and prejudicial effects when assessing the admissibility of such expert testimony. The court found no abuse of discretion in the trial court’s decision to exclude the expert testimony.
Facts
On December 27, 2008, an eyewitness was in front of a barbershop when a robbery and murder occurred. Four men entered the shop, demanding money and drugs. One man fatally shot the victim. Later, a witness identified the defendant in a lineup as one of the perpetrators. The getaway driver implicated the defendant in the crime. At trial, the defendant moved to introduce expert testimony on factors influencing eyewitness identification. The trial court initially denied the motion, but then granted permission to revisit the issue. After the prosecution presented its case, the defense renewed the motion to present the expert witness, which the trial court denied, concluding that the eyewitness testimony was corroborated by the getaway driver. The defendant was convicted on all counts.
Procedural History
The defendant was convicted by a jury in Supreme Court. The Appellate Division reversed the conviction, finding the trial court abused its discretion by precluding expert testimony on eyewitness identification. The New York Court of Appeals granted leave to appeal.
Issue(s)
1. Whether the trial court abused its discretion by precluding the defense from presenting expert testimony on the reliability of eyewitness identification.
Holding
1. No, because the trial court properly exercised its discretion in balancing the probative value of the expert testimony against its potential for prejudice or other harmful effects, given the corroborating evidence.
Court’s Reasoning
The Court of Appeals held that the trial court did not abuse its discretion by precluding expert testimony on eyewitness identification. The court reaffirmed that the admissibility of such expert testimony is within the trial court’s discretion. The court clarified that the trial court must weigh the request to introduce expert testimony against factors such as the centrality of the identification issue and the existence of corroborating evidence. The court emphasized that trial courts have the power to limit the amount and scope of evidence presented. The court found that, in this case, the trial court correctly balanced the probative value of the expert testimony against its potential for prejudice, particularly given the corroborating evidence from the getaway driver.
Practical Implications
This case provides a clear reminder of the trial court’s gatekeeping role in admitting expert testimony. Attorneys must be prepared to persuade the trial court that the expert testimony is necessary to assist the jury, considering the strength of other evidence. This case reinforces the importance of building a record that demonstrates the reliability of eyewitness identification, especially when corroborating evidence exists. The decision underscores that the admissibility of expert testimony on eyewitness identification is highly fact-dependent, with the trial court having broad discretion to make the ultimate decision. The decision can affect how attorneys prepare for trial, emphasizing the need to present clear arguments regarding the probative value and potential prejudice of proposed expert testimony.
