In June 2007, the parties entered into a Memorandum of Understanding whereby the respondent would repair the applicant municipality's plant, machinery and equipment at its own cost. The respondent would then use the equipment for its own business for a period equivalent to the costs incurred in repairs. The arrangement was for thirty days, subject to renewal, with no provision for monetary payment by the applicant. Subsequently, the respondent made several claims against the applicant totaling Z$13,122,622,511.77, then Z$446,144,473,404.72, and finally US$281,840.00. Despite the applicant's assertion that these claims had no legal basis, it paid a total of Z$271,000,000,000.00. However, the respondent refused to release the equipment even after payment. The original agreement listed only four pieces of equipment, but the applicant claimed ten pieces. The parties disputed whether the agreement was oral or written and whether further agreements had been entered into.
