The men will return to court in July to face 35 charges concerning a $300,000 loan from Talbot to Nuttall and the subsequent Beattie Government decision to finance a $20 million rail and road deviation to Macarthur Coal's Coppabella mine.
Both men say they are innocent of any wrongdoing.
When details of the loan were made public last year, Nuttall claimed the payments were personal loans to buy houses for his three children.
Talbot took a leave of absence from Macarthur in November last year, leaving deputy CEO Nicole Hollows to take the reigns.
At Brisbane Magistrates Court today, Commonwealth prosecutor Paul Rutledge requested the matter be adjourned to allow more time to gather material, ABC Online reported.
The matter has been adjourned until July 2.
