The DA and the Public Protector are back in court over her Vrede Dairy Farm report.
Busisiwe Mkhwebane is expected to argue against the review and setting aside of her report.
The DA and the Council for the Advancement of the South African Constitution want the report reviewed and set aside.
They argue her actions were unconstitutional on the matter.
Mkhwebane failed to name political principals like Ace Magashule and Mosebenzi Zwane and to hold them accountable for their conduct in the scheme.
The project saw millions of rands earmarked for developing a dairy project in the Free State making its way into the accounts of Gupta associates.
