Case Brief Summary & Legal Analysis
tl;dr: A New York court rejected a plaintiff’s attempt to use fMRI brain scan evidence to prove a key witness was telling the truth. The court held that assessing witness credibility is the exclusive job of the jury, not a matter for scientific experts.
Legal Significance: As a case of first impression, this decision establishes that fMRI lie-detection evidence is inadmissible in New York courts to bolster witness credibility, reinforcing the jury’s role as the sole arbiter of truthfulness and applying the Frye standard to novel neuroscientific evidence.

Case Facts & Court Holding
Key Facts & Case Background
Plaintiff Cynette Wilson sued her temporary employment agency, Corestaff Services, for retaliation. Wilson alleged that after she reported sexual harassment, a Corestaff manager, Edwin Medina, instructed another employee, Ronald Armstrong, not to give her any more work assignments. Armstrong was the sole witness to this alleged retaliatory statement, making his credibility a central issue in the case. To support Armstrong’s testimony, the plaintiff sought to introduce expert testimony from Dr. Steven Laken, who had administered a functional magnetic resonance imaging (fMRI) test to Armstrong. Dr. Laken was prepared to testify that the fMRI results showed, to a high probability, that Armstrong was being truthful about Medina’s statement. The defendants filed a motion in limine to preclude this expert testimony. The plaintiff cross-moved for a Frye hearing to determine the scientific admissibility of the fMRI evidence.
