While such a proposition may seem to make logical sense where an expert witness is simply testifying as to the consistency of ballistic evidence, or of foot prints, it is flawed when considering more subjective evidence. As the nature of an expert's testimony is inherently outside of a tribunal's understanding, the tribunal will not be well placed to consider the cogency or reliability of the expert's opinion.[1] This has led to high profile miscarriages of justice where certain experts have expressed particularly strong opinions on matters without strong scientific consensus, or where they are considered to be the leading expert in their field. In such instances, it has been difficult for the court to initially refuse to admit experts, given their testimony is often necessary in the instant case.
