Abstract

fetched live from OpenAlex

Expert witnesses are now an accepted part of criminal and civil trials. The use of expert witnesses and the admissibility of their science has developed over the last 250 years, when the concept of allowing an expert witness to give opinion evidence on the facts of other witnesses was allowed by Lord Mansfield in the case of Folkes v. Chadd in 1782. This paper briefly describes how court procedures have changed over the centuries before opinion evidence was admitted and then traces the history of the expert witness in England, USA, and Canada, examining issues of admissibility and duties of the expert from the 18th century to the 21st century. The paper further describes the change in admissibility with US decisions in Frye and Daubert and how they have affected courts in the UK and Canada. Also described are recent decisions in the UK on duties of experts and immunity from suit.

Full frame distilled prediction

Teacher imitation

Not 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.
