The applicant, a member of the legal fraternity, sought to declare Statutory Instrument 127 of 2021 unconstitutional. The instrument was promulgated by the first respondent (President of Zimbabwe) on 26 May 2021 and published in the Government Gazette Extraordinary. The applicant claimed to have an interest in human rights and the rule of law and brought the application under s 85(1)(d) of the Constitution. The instrument defined the relationship between the Reserve Bank of Zimbabwe and bankers, foreign exchange dealers and traders. The second respondent (Minister of Finance and Economic Development) opposed the application, arguing that the applicant lacked locus standi as he had no direct or substantial interest in the instrument, and that the rights of bankers, foreign exchange dealers and traders were more proximately affected.
