State of New Jersey, Plaintiff-Appellant v. Peter Vandeweaghe, Defendant-Respondent

Summary

The Supreme Court of New Jersey affirmed the Appellate Division's reversal of the murder conviction, holding that the trial court erred in admitting expert testimony on the defendant's antisocial personality disorder and certain police officer testimony. The Court found the expert evidence irrelevant, highly prejudicial, and not justified by the opening‑the‑door doctrine, and therefore affirmed the judgment of reversal and remanded for further proceedings.
