GEMS is a medical scheme registered under the Medical Schemes Act 131 of 1998. Mr Ngwato, whose life partner (Ms Rakgahla) was a GEMS member, sought to be recognized as her beneficiary after her death. GEMS initially refused, requesting a marriage certificate. After a policy change, GEMS recognized Mr Ngwato as a member but ruled he did not qualify for a GPAA subsidy. Mr Ngwato complained to the Registrar of Medical Schemes, who ruled against him on 19 January 2016. He appealed to the Council for Medical Schemes, which dismissed his appeal on 27 October 2016, confirming he was entitled to continued membership but must take up subsidy issues with GPAA. Instead of exercising his further right of appeal to the Appeal Board, Mr Ngwato lodged a complaint with the Public Protector in February 2016. The Public Protector initially closed the file as unsubstantiated but later decided to proceed with the investigation. On 24 April 2018, subpoenas were issued to GEMS' Principal Officer (Dr Goolab) and legal advisor (Mr Kruger). GEMS challenged the Public Protector's jurisdiction to investigate the complaint.
