Guard-Alert (applicant) was a member of the National Commercial Employers Association of Zimbabwe (the Association), while Mukwekwezeke (first respondent) was a member of the Commercial Workers Union of Zimbabwe (the Union). On 12 August 2009, an arbitrator made an award ordering Association members to pay Union members a minimum wage of US$150 per month for April-July 2009. The Association appealed to the Labour Court, which dismissed the appeal on 3 December 2010. On 17 December 2010, the Association and Union agreed to waive and abandon their rights arising from both the arbitral award and Labour Court judgment, agreeing instead to a wage of US$200 per month effective 1 January 2011. Despite this waiver, Mukwekwezeke (a self-actor lay person) filed multiple applications in the Magistrates' Court seeking to enforce the Labour Court judgment against Guard-Alert for alleged back pay of US$660. After his first summons (case 3068/11) was withdrawn and a second application for registration of judgment (case 4511/11) was dismissed on 11 May 2011, he filed yet another application (case 6633/11) on 12 May 2011 seeking the same relief. On 23 May 2011, Magistrate Tahwa (second respondent) ruled that there were material disputes of fact regarding whether Mukwekwezeke was part of employees who waived their back pay and referred the matter to trial. Guard-Alert then brought this review application.
