The second applicant was the Managing Director of the first applicant, a dental laboratory. The first respondent (Health Professions Authority Zimbabwe) levied a penalty of US$690.00 on 8 March 2021 under Statutory Instrument 78 of 2017 for non-compliance. The applicants paid ZWL$690.00 at a 1:1 rate pursuant to SI 33 of 2019, which provided for parity between RTGS dollars and US dollars. The first respondent accepted but rejected this payment as settlement, citing SI 85/2020 which required pricing in both Zimbabwe dollars and foreign currency at the ruling exchange rate. The first respondent then closed the applicants' laboratory on 17 March 2021 and instructed police to man the premises. The applicants launched an urgent application seeking to reopen the laboratory, declaring that their payment was valid, and restraining criminal proceedings. Evidence showed that the applicants had been notified as early as June 2020 and September 2020 (via email with proforma invoice) of the requirement to pay in US dollars or equivalent at the ruling bank auction rate, and had been operating without proper licensing for approximately two years.
