NJ Supreme Court Orders Reliability Hearing on Fingerprint Evidence in State v. Lee
State v. Lee: A Moorestown Burglary Case Built on Fingerprint Evidence
That fingerprint comparison became the centerpiece of the prosecution’s case, because it was the only physical evidence tying Lee to the burglaries. There was no eyewitness identification, no confession, and nothing else placing him inside the restaurant. Whether the State could convict depended entirely on whether the jury heard — and believed — the fingerprint match. That made State v. Lee far more than a routine burglary appeal. It became a test of how New Jersey courts must evaluate fingerprint evidence before trial.
Why the Defense Challenged the ACE-V Fingerprint Analysis
Lee’s defense team moved to bar the State’s fingerprint expert from testifying. Their argument was straightforward: before the jury hears a fingerprint identification, the State should have to demonstrate that the method used to reach that identification is scientifically sound. The defense grounded that argument in two influential reports on forensic science — the 2009 National Academy of Sciences report and the 2016 report from the President’s Council of Advisors on Science and Technology (PCAST).
Neither report concluded that fingerprint evidence is worthless. What they did raise were serious questions about how fingerprint comparisons are performed and how confidently examiners present their conclusions in court. Building on those findings, the defense identified several concerns: inconsistent results when different examiners review the same prints, the subjective judgment built into the ACE-V method, the absence of a uniform standard defining what counts as an “identification,” documented error rates in fingerprint comparison studies, and the risk of confirmation bias when an examiner already knows police have a suspect.
The defense emphasized that these concerns carried extra weight here, because the fingerprints were the only evidence connecting Lee to the restaurant. Without the match, the State had no eyewitness, no confession, and no other physical proof.
The trial court denied the motion without holding a separate reliability hearing. Rather than requiring the State to establish the scientific reliability of the analysis under current evidence standards, the court pointed to the long history of fingerprint evidence in New Jersey courtrooms. In effect, the trial court treated fingerprint comparison as settled science because New Jersey courts had admitted it for more than a century. The Supreme Court concluded that this reasoning was not sufficient once a defendant raises a legitimate, science-based reliability challenge.
What the NJ Supreme Court Ruled About Fingerprint Evidence
The New Jersey Supreme Court agreed with the Appellate Division that the trial court should have held a pretrial reliability hearing before permitting the State’s fingerprint expert to testify. Importantly, the Court did not hold that fingerprint evidence is inadmissible. It held that when a defendant raises a substantial, science-based challenge to fingerprint identification, the trial judge must perform a gatekeeping function before that testimony reaches the jury. Because Lee’s defense relied on respected forensic science reports questioning the reliability of ACE-V comparison, the court could not simply rely on the long track record of fingerprint evidence in New Jersey criminal trials.
The Court analyzed the question under N.J.R.E. 702, the rule governing expert testimony in New Jersey. Expert testimony is admissible only when three conditions are satisfied: the subject matter is beyond the understanding of an average juror, the field is reliable enough to support expert testimony, and the witness is qualified to offer that testimony.
The ruling also reflects a broader shift in how New Jersey courts assess scientific and technical evidence in criminal matters. For decades, courts applied the Frye “general acceptance” standard, asking whether a method was generally accepted within the relevant scientific community. In State v. Olenowski, the New Jersey Supreme Court moved criminal cases to a Daubert-style reliability analysis, directing courts to examine reliability directly rather than relying on historical acceptance alone.
That shift mattered enormously in Lee. Fingerprint evidence has been admitted repeatedly for over a hundred years, and the Court made clear that longevity is not a substitute for reliability review. The question is not whether fingerprint evidence has been admitted before. The question is whether, under current evidence law and current science, fingerprint methodology and expert conclusions are reliable enough to put before a jury.
What Happens Next: The Special Adjudicator’s Reliability Hearing
The Supreme Court did not decide whether fingerprint evidence, as it is actually practiced, satisfies New Jersey’s expert-testimony reliability standard. Instead, the Court appointed a Special Adjudicator — retired Appellate Division Judge Carmen Messano — to conduct a full plenary hearing on the question. At that hearing, both sides may present expert testimony, scientific studies, and other evidence bearing on whether latent fingerprint identification is reliable enough for use in New Jersey criminal trials.
The Special Adjudicator’s task is not limited to a yes-or-no answer. The Court also directed the hearing to address what limitations, safeguards, or conditions should apply if fingerprint evidence is found admissible. That could include how examiners are permitted to phrase their conclusions, whether an expert may claim a match to the exclusion of all other people, what error rate information must be disclosed, what jury instructions should accompany the testimony, and what procedures should be used to reduce examiner bias.
The Court retained jurisdiction over the case. Once the Special Adjudicator completes the hearing and issues findings, the matter returns to the Supreme Court, which will then address the central question it has so far left open: whether modern fingerprint comparison — specifically ACE-V latent print identification — meets New Jersey’s reliability standard under N.J.R.E. 702 and State v. Olenowski.
It is also worth being precise about what did not happen. Lee’s conviction was not reversed. The ruling does not declare the fingerprint evidence unreliable, and it does not automatically entitle him to a new trial. The next step is the reliability hearing. Only after that process concludes will courts determine what this ruling means for Lee’s conviction and for the future use of fingerprint evidence in New Jersey criminal cases.
What State v. Lee Means for New Jersey Criminal Defendants
State v. Lee appears to be the first time the New Jersey Supreme Court has ordered a dedicated hearing to test whether fingerprint evidence satisfies the State’s reliability standard. Rather than accepting fingerprint identification simply because courts have admitted it for more than a century, the Court called for a closer examination of whether the methods used today hold up under N.J.R.E. 702 and the Daubert-based framework adopted in Olenowski.
For defendants, this matters because fingerprint evidence carries outsized weight with juries. Many jurors assume a fingerprint match is close to infallible. Lee recognizes that courts still have to examine the science behind the expert opinion, particularly when the defense raises specific concerns about error rates, subjectivity, or bias. The ruling reinforces a principle that reaches well beyond fingerprints: expert testimony is not automatically admissible just because it comes from a familiar forensic discipline. New Jersey courts have applied similar scrutiny to other evolving evidence issues, including the recent ruling on geofence warrants and cell phone location data.
This does not mean fingerprints are on their way out of New Jersey courtrooms, and it does not mean every case involving fingerprint evidence will be dismissed. The Supreme Court has left the final reliability determination open. What Lee does establish is that defendants have a stronger footing to demand meaningful judicial review when fingerprint evidence sits at the center of the State’s case — whether at the trial level or on appeal.
Frequently Asked Questions About the NJ Fingerprint Evidence Ruling
What did the NJ Supreme Court decide in State v. Lee?
The Court did not decide whether fingerprint evidence is reliable. It ordered a special hearing to answer that question and appointed a Special Adjudicator, retired Judge Carmen Messano, to review the science and report his findings back to the Court.
Does this ruling mean fingerprint evidence is now inadmissible in NJ courts?
No. Fingerprint evidence remains admissible in New Jersey. The defendant’s conviction was not overturned, and the Court expressly declined to signal any opinion on how the upcoming reliability hearing should come out.
Why did the defense challenge the fingerprint evidence in this case?
The defense relied on the 2009 National Academy of Sciences report and the 2016 PCAST report, both of which raised concerns about examiner subjectivity, the absence of uniform identification standards, and documented error rates in comparison methods such as ACE-V.
What happens at the reliability hearing ordered by the Court?
Both the State and the defense may present testimony and other evidence, including expert witnesses. The Special Adjudicator will then issue a written report with findings on whether latent fingerprint identification meets New Jersey’s reliability standard for expert testimony.
How could this ruling affect future criminal cases in New Jersey?
Defense attorneys may have stronger grounds to request pretrial reliability hearings challenging fingerprint and other forensic evidence, instead of courts admitting that evidence based on its long history of acceptance alone.
Charged With a Crime Involving Fingerprint or Forensic Evidence in NJ?
If you are facing criminal charges in New Jersey and the State’s case rests on forensic evidence — fingerprints, DNA, trace evidence, cell phone data, or surveillance footage — that evidence deserves close scrutiny. A forensic match can be persuasive to a jury, but the State still has to show the evidence was lawfully obtained, properly tested, correctly interpreted, and accurately presented in court.
