The Opposition to Urban Tolling Alliance (Outa) plans to appeal a court ruling that thwarted its bid to have e-tolls in Gauteng scrapped.
"We are going to appeal. The formality is to get a mandate [from our members]," chairman Wayne Duvenage told Sapa on Friday.
The civil society organisation met with its lawyers on Friday to review the high court judgment.
"The meeting concluded that the judgment raised serious concerns which cannot go unchallenged."
On December 13, the High Court in Pretoria gave the green light to e-tolling, after it dismissed an application by Outa to get the system scrapped.
The court ordered Outa to pay the legal costs involved in the application.
On Friday, Duvenage said the organisation had begun discussions with its members about an appeal.
Outa's founding members are the SA Vehicle Renting and Leasing Association, the SA Tourism Service Association, Retail Motor Industries of SA, the Quadpara Association of SA, and the SA National Consumers Union.
Duvenage hoped to have officially obtained the mandate around December 28 and to raise funds from the public to take the case further.
The appeal had to be lodged with the court by January 9 next year.
Outa had fought a number of court battles this year to try and stop the implementation of the e-tolling system.
