The Judicial Admission of Faulty Scientific Expert Evidence Informing Wrongful Convictions
Bibliographic record
Abstract
The failure of a judge to properly conduct a voir dire to ensure an expert is sufficiently qualified to give evidence in a particular area may give rise to a wrongful conviction. Considering Recommendation 130 from the Goudge Inquiry, that âtrial judges should be vigilant in exercising their gatekeeping role with respect to the admissibility of [expert] evidenceâ, it is essential to examine recent shortcomings of judicial vigilance in admitting expert evidence and to consider how to remedy similar errors in future cases.\nThe major shortcoming of judicial gatekeepers in admitting expert evidence is the improper application of case law regarding the test in R v Mohan and consideration of the factors in Daubert. Systemic patterns of judicial error are demonstrated through the repeated admission of expert evidence given by Doctors Charles Smith and Gideon Koren. By analyzing the flaws in Dr. Smithâs admitted testimony in the context of the Mohan test, and the misapplication of the Daubert factors to Dr. Korenâs evidence, it is clear that the gatekeeperâs acceptance of unqualified or underqualified expert evidence can be avoided by holding fulsome voire dires and adopting techniques utilized in other jurisdictions to reduce the potential of wrongful convictions.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
