A superior court will only interfere with unterminated criminal proceedings in a lower court in exceptional circumstances where: (1) there is a proven gross irregularity or clearly wrong decision; (2) the irregularity vitiates the proceedings; (3) it gives rise to a miscarriage of justice; (4) it seriously prejudices the rights of the accused; and (5) the prejudice cannot be redressed by any other means, including appeal after completion of the trial. An applicant seeking to stay criminal proceedings pending review must prove that the review application has prospects of success by demonstrating all of these elements. The mere fact that a trial court's interlocutory decision may be wrong, irregular, or cause prejudice is insufficient grounds for intervention if these matters can be corrected on appeal. At the discharge stage under section 198(3) of the Criminal Procedure and Evidence Act, "no evidence" means no evidence upon which a reasonable person might convict; if there is evidence requiring a reply from the accused, discharge must be refused.
