Rule 702 After Fifteen Years of Daubert in North Carolina

North Carolina's expert-testimony rule has read like its federal counterpart for a decade and a half, and for most of that period, commentators have debated whether trial judges actually apply it the way the amendment's drafters intended. This article takes up that question directly, using a sample of reported and unreported trial court rulings on expert admissibility to ask whether the state's gatekeeping standard functions as a real filter or as a formality recited on the way to letting the jury decide.

What changed, and what did not

The 2011 amendment moved North Carolina's rule for admitting expert testimony away from a more permissive standard and toward language requiring trial judges to assess the reliability of an expert's methodology before allowing testimony to reach the jury, not merely the expert's qualifications. Appellate decisions in the years that followed confirmed that this was a substantive change, not a stylistic one, and articulated factors trial courts should weigh in making that assessment.

What the amendment could not change by itself was the practical posture of a trial judge asked, often on the eve of trial, to exclude an expert whose testimony one side has built its case around. The doctrinal standard shifted; the institutional pressure not to exclude did not.

A gatekeeping role exercised unevenly

The rulings reviewed for this article show real variation in how seriously the gatekeeping inquiry is conducted. Some trial courts hold extended hearings, request supplemental briefing on methodology, and issue rulings that engage substantively with an expert's reasoning. Others resolve reliability challenges in a paragraph, reciting the governing factors without visible analysis of how the facts before the court satisfy or fail them.

This unevenness is not unique to North Carolina, and it is not new; it is a documented feature of gatekeeping regimes generally. What this article adds is a closer look at where the variation falls — by case type, by procedural posture, and by whether the challenge arose in a civil or criminal matter — and an argument that some of that variation is more troubling than the rest.

Where the stakes are highest

Gatekeeping performed thinly matters least when the underlying expert opinion is uncontroversial and consistent with the broader body of methodology in its field. It matters most in the categories of case where an unreliable opinion is most likely to be outcome-determinative and least likely to be corrected by cross-examination alone — a category this article argues includes certain forensic disciplines whose underlying methodologies have drawn sustained scrutiny in the broader literature over the past fifteen years.

Conclusion

Fifteen years after North Carolina adopted a Daubert-style standard on paper, this article's central claim is modest but, it argues, important: the standard's existence has not guaranteed its exercise, and the difference between the two is not evenly distributed across the kinds of cases where it matters most. A rule can change what judges are asked to do without fully changing what they do.
