In March 1992 the appellant, Frank Peter Zanner, fatally injured a co-employee, Samuel Tumisang Segaetso, in a factory workshop by striking him with a vernier measuring instrument. Whether the vernier was thrown intentionally or slipped from the appellant’s hand was disputed. After an initial police investigation and an inquest in 1992–1993, the appellant was charged with culpable homicide in 1993, but the charge was withdrawn in January 1994 following representations made on his behalf. More than ten years later, in April 2004, the Director of Public Prosecutions re-indicted the appellant on a charge of murder relating to the same incident after the matter was re-investigated. The appellant applied for a permanent stay of prosecution, contending that the long delay infringed his right under s 35(3)(d) of the Constitution to have his trial begin and conclude without unreasonable delay and caused irreparable trial-related prejudice.
