The ACLU-NJ, as friend-of-the-court, argued that Child Sexual Abuse Accommodation Syndrome or "CSAAS" is not scientific, and therefore expert testimony regarding CSAAS expert testimony cannot be admitted as part of a criminal case against a defendant. Because CSAAS is not scientific, admitting expert CSAAS testimony violates a defendant's right to Due Process.
After special remand to the trial court for an admissibility hearing under New Jersey Rule of Evidence 104, Judge Bariso found that CSAAS testimony is unscientific and therefore inadmissible. The Supreme Court thereafter heard argument and issued an opinion on July 31, 2018. The Court held that most CSAAS testimony was insufficiently reliable to be admissible at trial.
