The court observed that: (1) The Constitutional Court Rules, 2016 (which came into operation after this referral was made) have not created new requirements but have simply incorporated sentiments expressed by the court in various previous cases; (2) Section 24 of the Constitutional Court Rules, 2016 provides for the procedure to be followed in referrals, including that where there are factual issues, the court must hear evidence and determine those issues, and where there are no disputes of fact, parties must prepare a statement of agreed facts; (3) There are cases where leading evidence will not be necessary, particularly where facts are common cause, and requiring evidence in such cases would serve no meaningful purpose; (4) Cases such as S v Njobvu, S v Banga, Sivako v AG and Douglas Mwonzora v The State, which stress the need for viva voce evidence, were decided in the context of applications for permanent stay where various factual matters such as length of delay, reasons for delay, prejudice and assertion of right to speedy trial must be traversed; (5) The present case was different from permanent stay applications as it concerned the constitutionality of a statutory provision rather than delay in prosecution.
