On 21 October 2008, two employees of the Reserve Bank of Zimbabwe (the plaintiffs) were traveling from Mutare to Harare in a Toyota Camry in the course of duty. At the 235.5 kilometer peg after the Mutare River Bridge, their vehicle had a violent collision with a vehicle driven by the second defendant, which was insured by the first defendant (Nicoz Diamond Insurance Co). The plaintiffs sued both defendants for damages arising from the second defendant's alleged negligent driving. The first plaintiff claimed US$125,000 and the second plaintiff claimed US$190,000, both plus costs and interest. In its initial pleadings, the first defendant (insurer) failed to plead that the plaintiffs' claims were limited to Zimbabwean Dollars only in terms of the insurance policy. The first defendant subsequently filed a chamber application seeking to amend its plea to incorporate this limitation, explaining that although they gave their lawyers specific written instructions to include this plea, it was inadvertently omitted.
