The binding legal principles established are: (1) The constitutional right to a fair hearing within a reasonable time under section 18(2) of the Constitution of Zimbabwe is triggered when a person is 'charged' in the substantive sense, which includes when an accused records a warned and cautioned statement, not merely when formally arraigned or called to plead; (2) In assessing whether there has been an unreasonable delay violating this constitutional right, courts must consider four factors: (i) the length of the delay, (ii) the reasons for the delay, (iii) whether the accused asserted their rights, and (iv) the prejudice suffered by the accused; (3) Of these factors, prejudice that impairs the accused's ability to mount a full and fair defense is the most serious, as it skews the fairness of the entire system; (4) Delays of over 12 years are considerable and, where attributable to the state rather than the accused, and where real prejudice is demonstrated (including loss of memory, unavailability of witnesses, anxiety, and inability to prepare an adequate defense), will justify a permanent stay of prosecution; (5) An accused cannot be expected to continually assert rights to a speedy trial when officially informed by authorities that the case has been closed; (6) Evidence not placed before a lower court cannot ordinarily be adduced on referral to a higher court without proper legal basis and good explanation for its previous non-production.
