Unanimous Judgment Read By — Moldaver J.

Moldaver J. — We are all of the view that the appeal must be allowed, for the reasons of Justice Pepall, with which we agree.
We would simply underline that when assessing the credibility and reliability of testimony given by an individual who has an intellectual or developmental disability, courts should be wary of preferring expert evidence that attributes general characteristics to that individual, rather than focusing on the individual’s veracity and their actual capacities as demonstrated by their ability to perceive, recall and recount the events in issue, in light of the totality of the evidence. Over-reliance on generalities can perpetuate harmful myths and stereotypes about individuals with disabilities, which is inimical to the truth-seeking process, and creates additional barriers for those seeking access to justice.
Accordingly, we would allow the appeal and restore the conviction.
