The case relates to procurement fraud involving R24.9m paid by the Free State department of agriculture to Nulane Investments.
A feasibility study was contracted to Nulane Investments by the Free State government to check the likelihood of success of the Mohoma Mobung agriculture project.
Nulane Investments, however, had no employees on its books and subcontracted Deloitte to produce the report.
Deloitte was paid R1.5m for the work.
The only change made to the Deloitte report was to identify Paras dairy as a suitable implementing partner for the development of a milk processing plant in Vrede.
In July, the ID said efforts to bring the Gupta brothers and their wives back to SA to face charges had intensified, with Interpol issuing red notices for their arrest.
Atul Gupta and his wife Chetali, Rajesh Gupta and his wife Arti, and three others are wanted to join the other accused.
The matter was postponed to October 8.
