A delay of over 7 years in bringing accused persons to trial, without adequate justification, constitutes an infringement of the constitutional right to a fair hearing within a reasonable time and warrants a permanent stay of prosecution. In determining whether delay is unreasonable, courts must consider: (1) the reason for the delay; (2) the assertion of rights by the accused; (3) prejudice arising from delay; (4) conduct of both prosecutor and accused; and (5) the seriousness and complexity of the offence. While more serious and complex offences may justify longer investigation and prosecution periods than simple cases, there is a limit beyond which delay becomes unconscionably excessive regardless of the gravity of the charge. The burden rests on the State to provide reasonable explanation for delay. Inadequate explanations such as fuel shortages that have long since ended, or failure to apply timeously for separation of trials when co-accused abscond or die, will not justify prolonged delay.
