In 2017, following publication of a book alleging that former President Zuma received a salary from Royal Security CC for four months after becoming President in 2009 and failed to pay income tax on it, opposition leader Mmusi Maimane lodged a complaint with the Public Protector. In 2018, during her investigation, the Public Protector issued a subpoena to the Commissioner for SARS to produce former President Zuma's taxpayer information. The Commissioner objected, citing section 69(1) of the Tax Administration Act 28 of 2011, which prohibits disclosure of confidential taxpayer information. The parties jointly obtained senior counsel's opinion (Advocate Maenetje SC), which concluded the Public Protector's subpoena powers do not extend to compelling disclosure of taxpayer information. The Public Protector, dissatisfied, obtained a second opinion (Advocate Sikhakhane SC) which concluded her constitutional powers trump the statutory prohibition. She did not share this opinion with the Commissioner but issued a second subpoena. The Commissioner then approached the High Court for declaratory relief and sought a personal costs order (de bonis propriis) against the Public Protector.
