|---|
There is a well-settled maxim that the standard of persuasion in criminal trialsproof beyond a reasonable doubtis unquantifiable. However, the usual reasons given for the unquantifiability of reasonable doubt are unsatisfactory; and a recent case, United States v. Copeland, serves as a reminder that strong considerations favour quantification of at least some standards of persuasion. This comment attempts to bring greater clarity to the question of the advantages and disadvantages of some form of quantification of the reasonable doubt standard.
