BDO Zimbabwe Chartered Accountants, a private partnership of chartered accountants, was contracted by the Auditor General of Zimbabwe to conduct a forensic audit of the National Social Security Authority (NSSA) for the period January 2015 to February 2018. Robin Vela had been the board chairman of NSSA from July 2015 to March 2018. The forensic audit produced adverse findings against Vela, including overpayment of board fees, interference in management issues, and questionable dealings with Medbank investments that yielded losses. Vela brought a review application in the High Court under section 3(1)(a) read with section 4 of the Administrative Justice Act, arguing that BDO was exercising public power subject to judicial review, that the audit was conducted without jurisdiction, and that it was biased, malicious, irrational, incompetent and unfair. The High Court upheld the review and set aside the forensic audit report insofar as it pertained to Vela, with costs at the higher scale. Both BDO and the Auditor General appealed to the Supreme Court in two consolidated appeals.
