Opposite sides of the same coin: syndrome evidence, child abuse and the wrongful conviction of Peter Hugh McGregor Ellis

Abstract

Introduction of evidence relating to the now-discredited behavioural-science syndrome known as ‘child sexual abuse accommodation syndrome’ in R v Ellis demonstrates the danger of syndrome reasoning in judicial fact finding. Comparable syndrome evidence is still used in the Family Court in the form of ‘parental alienation syndrome’. Ellis should sound the death knell for all forensic applications of unreliable syndrome reasoning in the courts.
