Professor Notes

In People v. Ennis, the New York Court of Appeals highlights the critical importance of corroborating eyewitness testimony, particularly when it serves as the sole basis for conviction. The case reflects the court's insistence on robust evidentiary standards to prevent wrongful convictions based on unreliable identification, especially when factors like distance and lighting contribute to potential misidentification. Professors will likely emphasize the need for jurors to consider the quality and circumstances surrounding eyewitness identifications during deliberations.
