The Opposition to Urban Tolling Alliance (OUTA) is due to meet an inter-ministerial committee to discuss e-tolling on Thursday.

The project was halted by a Pretoria court in April, but government is now appealing that decision in the Constitutional Court.

Thursday’s consultation is the latest in a series of meetings chaired by Deputy President Kgalema Motlanthe.

The alliance's Wayne Duvenage said they hoped to have an open discussion about the costs of the project.

“We want to know if there’s an appetite for change,” explained Duvenage.

“We need to get the message across that society in general does not accept e-tolling.”

Earlier this month, Motlanthe told a meeting between Business Unity South Africa (Busa) and the inter-ministerial committee that e-tolling would alleviate congestion on the roads.

Motlanthe said Gauteng is at the heart of South Africa’s economy and delays on the roads have far-reaching consequences.

“Congestion has a negative impact on the economy as a whole, because it slows down movement of people and goods.”

In April, the implementation of the contentious tolling project was halted, after Judge Bill Prinsloo granted an urgent interdict to OUTA.

Prinsloo agreed that further analysis of e-tolling needed to be looked at, while government approached the Constitutional Court to challenge the ruling.

The organisation claims the "user-pays principle" is not the preferred alternative, but rather supported the possibility of an additional fuel levy to cover the costs of the project.
