Justice Anthony Besanko ordered Seven and Australian Capital Equity to hand over invoices and emails that showed the involvement of their lawyers in the hotly contested litigation with a 110-day hearing ending last year.
Seven and ACE unsuccessfully argued the documents merely revealed how often the lawyers sat in on the hearings and would not show that the firms had any control or management of how the war veteran ran the lawsuits.
The two Stokes-backed firms financially supported the Victoria Cross-recipient through the litigation via loan agreements which stated Seven's lawyers would have "continued oversight and management" of the litigation.
"The company understands there is a strong case to defend your reputation and the unfairness of your treatment by the defendants and in the inquiry proceedings," ACE said in its loan agreement with Mr Roberts-Smith.
"The company is therefore willing to make this funding available to you in the belief there is a strong case for a successful outcome to the proceedings."
ACE requested an additional 15 per cent on top of the repayment of any money loaned to the former SAS corporal if he won his lawsuits.
After the cases were thrown out in the Federal Court last month, Nine-owned publishers The Age and The Sydney Morning Herald plus The Canberra Times are seeking their legal costs which are estimated to be over $25 million in total for all parties.
Mr Roberts-Smith has already agreed to cover the legal bills as well as paying additional indemnity costs after March 17, 2020, a day before the three media companies made an offer to resolve the proceedings.
He is resisting calls that he pay indemnity costs before that date, however.
Other offers to settle the lawsuits were made on June 13, 2019 and November 30, 2020.
The bid against Seven and ACE is also for indemnity costs, which are orders typically granted in lawsuits that are frivolous, hopeless or doomed to fail.
Almost five years after the lawsuits were commenced, Justice Besanko dismissed the cases, finding reports Mr Roberts-Smith engaged in war crimes while deployed in Afghanistan, including his involvement in the unlawful murder of four unarmed prisoners, were substantially true.
Mr Roberts-Smith has until July 12 to file an appeal.
In November 2020, a report into alleged war crimes by special forces in Afghanistan was released, finding credible evidence 39 civilians and prisoners were unlawfully killed by Australian troops while two others were subject to cruelty from 2007 to 2013.
Two years later, more than 40 alleged offences were under investigation.
Mr Roberts-Smith has not been charged and maintains his innocence.
