HARARE – Luke Malaba will not sit on the seven-member bench of the Constitutional Court of Zimbabwe set to hear a high-stakes case challenging proposed constitutional amendments that could extend President Emmerson Mnangagwa’s rule to 2030. Malaba is expected to step down on May 14, just days before the matter is scheduled to be heard on May 20, effectively excluding him from proceedings in what is shaping up to be a landmark constitutional case.
