Opposition to the Urban Tolling Alliance (Outa) said on Saturday the next step in the legal battle against e-tolling would be to secure a full record of how the R20-billion project came about.
Outa's statement came in the wake of its court victory to put the tolls on hold for now. E-tolls were expected to go live today.
In March this year Sanral chief executive Nazir Alli handed censored documents to Cosatu general secretary Zwelinzima Vavi during a discussion on e.tv.
Transport Minister Sbu Ndebele instructed the Sanral board to make available all information about the project.
The board said it would consider making public the documents that Sanral provided voluntarily to Cosatu, but this has not happened.
"We will go to court to get a full record. We are entitled to ask for the record ...," Outa chairman Wayne Duvenage said.
But it was unclear when Outa would go to court for the record, or how long the court review process would take.
On Saturday the High Court in Pretoria granted an urgent interdict to halt the contentious e-toll project in Gauteng.
After being postponed five times the e-toll system will now have to wait for the outcome of a court review.
The ANC later announced that e-tolls would be delayed by another month.
