Optivest Health Services (Pty) Ltd (Optivest) is accredited as a broker by the Council for Medical Schemes (the Council) in terms of section 1, read with section 65 of the Medical Schemes Act 131 of 1998 (the Act) and its regulations. In May 2019, the Council received an anonymous tip-off from a former employee of Optivest alleging that Optivest was charging service fees to members who had resigned from medical schemes but were still being debited, without members' knowledge or consent, for over ten thousand "orphan" service fee profiles. The Council's Compliance and Investigation Unit formed the view that the allegations warranted further investigation. On 30 August 2019, the Registrar appointed Open Water Advanced Risk Solutions (Pty) Ltd (Open Water) in terms of section 44(2) of the Act, read with section 134(1), 129(2) and (3) of the Financial Sector Regulation Act 9 of 2017 (FSR Act), to conduct an inspection into Optivest's affairs. The inspection was conducted on 21-22 October 2019 and continued on 14 November 2019. Optivest initially cooperated but then withdrew cooperation and challenged the Council's authority. Open Water produced a second draft investigation report dated 29 November 2019 containing preliminary findings against Optivest. On 10 December 2020, Optivest instituted review proceedings seeking to set aside the decisions to initiate the investigation, appoint Open Water, and the draft report itself.
