Parliament of the United Kingdom, War Crimes Act 1991 (1991)
“ If the judge gives leave permitting, or makes an order requiring, a person to give oral evidence, but that person does not do so, the judge may disregard any document indicating the evidence that he might have given. (5) Dismissal of the charge, or all the charges, against the applicant shall have the same effect as a refusal by examining magistrates to commit for trial, except that no further proceedings may be brought on a dismissed charge except by means of the preferment of a voluntary bill of indictment. ”
