"Judgment will be handed down tomorrow, Friday, August 16 at 2pm," the court said in a statement on Thursday.
Friday also marks the commemoration of the day, on which 44 people were killed during strike-related unrest at Lonmin's platinum mine in Marikana last year.
Police shot dead 34 striking mineworkers. Ten people, including two police officers, were killed in the preceding week.
The legal costs relate to the Farlam commission of inquiry, which is investigating the massacre.
Advocate Dali Mpofu, representing the Marikana mineworkers wounded and arrested last year, announced on July 15 the decision to withdraw, pending a North Gauteng High Court ruling on his application for the state to fund the legal team.
"Our instructions [from the mineworkers] are to await the judgment and at that point to receive further instructions. In the meantime, we will not be participating for the victims," he said.
"If we are back later on in the week, we will have the extra burden of catching up with what would have happened [at the commission]. We have been consulting with a small delegation of the victims now. We are still going to consult with the larger groups."
On June 21 Mpofu told the commission that, due to financial constraints, it could be his last day representing the miners.
He then brought the urgent court application seeking funding for representing the mineworkers.
The commission was postponed on Wednesday pending the court's decision. – Sapa
