JOHANNESBURG - The South African National Roads Agency Limited (Sanral) is expected to hand over information this week, the Opposition to Urban Tolling Alliance (Outa) said on Tuesday.
The documents will be used in the enquiry into the controversial Gauteng e-tolling system.
In April, the North Gauteng High Court in Pretoria granted an urgent interdict against the system pending a legal review.
A few days after the ruling, Sanral CEO Nazir Alli resigned from his post.
The deadline to appeal the ruling has now lapsed.
Outa lawyer Pieter Conradie said they have also requested papers from the Departments of Transport and the Environmental Affairs Ministry.
The court review can only proceed once Outa receives the necessary papers.
Conradie will then have to draft new affidavits.
If the e-tolling system is implemented, Gauteng motorists will pay to use a 185kilometre stretch of the N1, N3, N12 and R21 highways.
