The New Jersey Supreme Court’s unanimous decision in State v. Lee, 2026 N.J. LEXIS 573 (June 29, 2026), marks a significant development in the law governing the admissibility of expert forensic testimony. In a case in which five latent fingerprints constituted the sole direct evidence linking the defendant to two restaurant burglaries, the Court held that a trial judge may not admit challenged fingerprint identification testimony on the strength of historical acceptance alone. When a defendant presents legitimate, science-based concerns about the reliability of the ACE-V methodology—subjectivity among examiners, repeatability, documented error rates, confirmation bias, and the absence of uniform objective standards—the court must conduct a pretrial evidentiary hearing under N.J.R.E. 702 and N.J.R.E. 104 before the evidence reaches the jury.
This ruling is the first major appellate application of the reliability framework adopted in State v. Olenowski, 253 N.J. 133 (2023). It reinforces the judiciary’s gatekeeping obligation and supplies defense counsel in fingerprint-dependent cases with a powerful, citeable tool to demand substantive litigation rather than routine admission.
The Facts and Procedural History of State v. Lee
In September 2018, a Moorestown restaurant was burglarized on two occasions. Police recovered five latent fingerprints from the scene. A fingerprint examiner concluded, through AFIS search followed by ACE-V analysis, that the prints matched French G. Lee. He was indicted on two counts of third-degree burglary. Lee moved pretrial to bar any expert testimony concerning fingerprint analysis, submitting authoritative scientific literature (the 2009 National Academy of Sciences report and the 2016 President’s Council of Advisors on Science and Technology report) that raised serious questions about the repeatability, subjectivity, and error rates of the discipline.
The trial court conducted only oral argument and admitted the evidence, reasoning that fingerprint identification had been accepted in New Jersey courts for more than a century and that Lee had failed to demonstrate a material change in scientific understanding. Lee was convicted.
The Appellate Division reversed, finding that reliance on historical acceptance rather than a focused reliability assessment under N.J.R.E. 702 constituted reversible error. The Supreme Court granted certification and affirmed the need for a hearing, but declined to overturn the conviction pending further proceedings.
Chief Justice Rabner, writing for the unanimous Court, appointed retired Appellate Division Chief Judge Carmen Messano as Special Adjudicator to conduct a plenary evidentiary hearing. The Special Adjudicator must determine (1) whether the fingerprint evidence presented at Lee’s trial satisfies the requirements of Olenowski I; (2) whether any limitations or guardrails should apply to the admission of fingerprint evidence going forward; and (3) if so, what those limitations or guardrails should be. The Supreme Court retained jurisdiction and will address the conviction (and the deferred voir dire and video-narration issues) after the record is developed.
The Governing Legal Framework: From Historical Acceptance to Rigorous Reliability Assessment
N.J.R.E. 702 provides that expert testimony is admissible if specialized knowledge “will assist the trier of fact to understand the evidence or to determine a fact in issue” and the witness is properly qualified. For decades, New Jersey applied the Frye general-acceptance test in conjunction with the three-prong foundation articulated in State v. Kelly, 97 N.J. 178 (1984): the subject must be beyond the ken of the average juror, the field must be at a state of the art permitting sufficiently reliable testimony, and the witness must be qualified.
Olenowski I changed the landscape. Recognizing that Frye’s focus on general acceptance was both too narrow and too difficult to apply to emerging or evolving disciplines, the Court adopted a Daubert-type reliability standard for all expert evidence—scientific, technical, or specialized—in criminal and quasi-criminal cases. Under Olenowski I, the proponent (ordinarily the State) bears the burden of establishing that the testimony rests on sound methodology. Relevant considerations include testability, peer review and publication, known or potential error rates, the existence and maintenance of standards and controls, and general acceptance (now one factor among many, not the sole criterion).
State v. J.L.G., 234 N.J. 265 (2018), provided an earlier illustration of this evolving approach. There, the Court excluded most Child Sexual Abuse Accommodation Syndrome testimony after concluding that the scientific community no longer supported the full syndrome as reliable, while preserving a narrow, fact-specific exception for delayed disclosure when helpful to the jury.
Lee applies the same principled gatekeeping to latent-print evidence: historical acceptance is no longer dispositive once a defendant raises legitimate, documented concerns drawn from authoritative scientific sources. The Court expressly noted that older federal decisions such as United States v. Mitchell, 365 F.3d 215 (3d Cir. 2004), which predated the NAS and PCAST critiques, do not relieve trial judges of the obligation to conduct a fresh reliability inquiry under current standards.
Practical Impact for New Jersey Criminal Defense Practice
State v. Lee fundamentally alters motion practice, trial preparation, and negotiation dynamics in any case in which latent-print evidence plays a material role—burglary, robbery, homicide, sexual assault, or any offense where prints are an evidentiary link to the accused.
First, defense counsel should evaluate every fingerprint case for a timely, detailed N.J.R.E. 104 motion. The motion should attach or reference the NAS and PCAST reports, articulate specific methodological flaws (subjectivity of ACE-V decision points, lack of validated error-rate studies under field conditions, confirmation bias risks, absence of objective minimum-ridge or quality thresholds), and request a plenary hearing with live expert testimony. Lee makes clear that oral argument alone is insufficient when legitimate scientific challenges are advanced.
Second, retaining a qualified defense forensics expert is now essential in appropriate cases. That expert can testify on the scientific literature, critique the State’s methodology in the specific case (e.g., print quality, distortion, examiner training and proficiency records), and propose guardrails if the evidence is deemed admissible (for example, prohibiting unqualified “match to the exclusion of all others” testimony, requiring disclosure of the number of corresponding points and any discrepancies, or limiting statistical claims).
Third, the decision strengthens negotiation leverage. Prosecutors facing a well-supported reliability motion must now weigh the cost and uncertainty of a full hearing—including potential appellate review and the risk of exclusion or severe limitation—against the benefits of a negotiated disposition. In cases where fingerprint evidence is the linchpin, this can meaningfully improve plea offers or lead to dismissal of charges that rest on questionable forensic links.
Finally, Lee underscores the importance of preservation. Even if the trial court denies a hearing, counsel should make a clear record and, where appropriate, request a limiting instruction or strike the testimony. The Supreme Court’s retention of jurisdiction in Lee signals that it will scrutinize both the hearing process and any resulting admission decision.
A Measured Yet Meaningful Step Forward
State v. Lee does not declare fingerprint evidence inadmissible. It does require that, when challenged with credible scientific literature, such evidence must earn its place before the jury through a rigorous reliability assessment rather than rest on tradition. In doing so, the decision reinforces the judiciary’s gatekeeping role, protects the integrity of the fact-finding process, and equips counsel defending serious charges with the tools necessary to litigate forensic evidence substantively and effectively.
For attorneys handling complex criminal matters in New Jersey, Lee is a reminder that zealous advocacy includes insisting that long-accepted forensic disciplines meet modern standards of scientific reliability. The Supreme Court has made clear that constitutional fairness demands nothing less. The full development of the record on remand will provide further guidance, but the principle is now firmly established: in New Jersey, reliability is not assumed—it must be demonstrated.
