Following the WHO's declaration of COVID-19 as a global pandemic on 11 March 2020, the President of Zimbabwe declared COVID-19 a state of disaster under s 27(2) of the Civil Protection Act. The Minister of Health and Child Welfare enacted the Public Health (COVID-19 Containment and Treatment) Regulations 2020 (SI 77/2020) under s 64(1)(a) of the Public Health Act, declaring COVID-19 a formidable epidemic disease. On 28 March 2020, the President announced a 21-day lockdown starting 30 March 2020, given legal effect through SI 83/2020. The lockdown was subsequently extended through various statutory instruments. SI 99/2020 imposed substantial amendments including: allowing formal businesses to open while restricting informal sector operations; mandatory COVID-19 screening and testing; mandatory face masks; and restricting public transport services to ZUPCO only. The applicants, representing informal workers and passenger associations, challenged these regulations as unconstitutional and ultra vires the enabling legislation. The application was initially dismissed by Dube J on 26 May 2020, but the Supreme Court upheld an appeal on 12 March 2021 and remitted the matter for a hearing de novo before a different judge.
