Study notes for State v. McKnight: professor notes, cold call prep, exam angles, and memory aids.

Expert testimony based on novel scientific techniques is admissible if the methodology is sound and relevant under the Daubert standard.
Professor Notes

In State v. McKnight, the New Jersey Supreme Court addressed the critical issue of expert testimony based on novel scientific techniques. The court reaffirmed the Daubert standard, which emphasizes that the admissibility of expert testimony hinges upon its reliability and relevance, rather than strict adherence to scientific consensus. This case illustrates the balance that courts must maintain between allowing innovative scientific methods to inform the jury and ensuring that such evidence meets rigorous standards of reliability. Professors may emphasize the importance of the methodology's soundness and application in evaluating such evidence.
