Both parties are corporate entities registered under Zimbabwean law. Plaintiff (Ultra Resources) operates in building construction and maintenance services, while defendant (PSMI) operates in the medical sector. Plaintiff issued summons claiming US$1,517,933.09 plus interest and costs for alleged non-payment by defendant for construction and maintenance services rendered under a "Service Level Contract" (SLA). The SLA contained clause 8, an arbitration agreement, which provided for dispute resolution by arbitration through the Harare Commercial Arbitration Centre. Defendant admitted indebtedness but contested quantum and currency. Defendant raised a special plea of jurisdiction, contending that plaintiff had evaded the arbitral dispute resolution procedure prescribed in clause 8 of the SLA.
