The National Treasury has applied to the Pretoria High Court to intervene in the Gauteng e-toll case to be heard this week.
Treasury said in a statement this morning that there would be serious negative implications for future financing of roads and investment in public transport, were the SA National Roads Agency Limited be interdicted from implementing the toll collection system.
Several lobby groups have applied for an interdict to stop the introduction of e-tolling on Gauteng roads scheduled for the 30th of this month while Cosatu is threatening another national strike.
The Treasury says it will argue that the interdict should be denied and the implementation of toll collection should be permitted to proceed, as has been decided by Cabinet and in keeping with the provisions of the Sanral Act.
Meanwhile, the Democratic Alliance says Sanral was misleading the public by displaying only one tariff on its sign boards at toll gantries.
DA Gauteng MPL, Neil Campbel says all three tariffs on all classes of vehicles should, and must, be displayed to the road user.
Campbell said the agency's "incomplete disclosure", by displaying only the discounted rate which applied to registered e-tag users, was a tactic to paint itself in the "best possible light".
