Treatment of Expert Witness Evidence in English Law

Trials decide the innocence or guilt of the defendant beyond any logical doubt or establish if the plaintiff has proven their argument on “balance of probability” to ensure justice. Administration of justice in a legal system is dependent upon two things: the existence of relevant operative facts; and the applicability of guiding rules to such facts which result in a determination of final judgment. To achieve the first of these, an exceptionally technical set of rules including the “law of evidence” has been developed. The law of evidence aims for the identification of material which is then required to be examined by the trier of facts.
