Judicial gatekeeping on expert testimony is often discussed as a concern about junk science – with an implication that anything not plainly lacking in scientific basis is a mere question of persuasiveness that should therefore go to the jury. The New Jersey Appellate Division recently took that concept to its extreme conclusion, holding that whenever a well-credentialed expert relies on some sort of scientific data and can offer an explanation for his conclusions, that testimony must be admitted, no matter the methodological flaws. Those flaws go merely to the strength of the testimony, the panel determined, and weaknesses can be exposed on cross examination and countered by other experts. As a result, the trial judge’s studied judgment to bar flawed expert testimony in the ongoing In re Accutane Litigation was reversed.
