The Opposition to Urban Tolling Alliance (Outa) filed responding papers in the Constitutional Court on Monday, chairman Wayne Duvenage said.
“Outa filed its answering affidavit for Treasury's leave to appeal the e-toll interdict in the Constitutional Court today,” he said.
The government approached the Constitutional Court arguing that the decision to halt e-tolling would negatively affect the economy.
In its reply, Outa said the SA National Roads Agency Limited was still not ready to launch the project.
Under the e-toll project, motorists will pay over 35 cents a kilometre to travel on some of Gauteng's freeways.
The project was to have been launched on April 30, but was postponed for a month after a meeting between the ANC and its alliance partner, the Congress of SA Trade Unions. - Sapa
