The DA has given Sanral four days to furnish them with the missing items in the e-tolling contract documentation.
The Democratic Alliance requested the 5 848 page document via a Promotion of Access to Information Act (Paia), but the tender documents' financial memorandum and two other items of the electronic toll collection submission were not included.
"[Monday] we sent a letter to the information officer requesting the complete documentation, and we will wait to see what happens this week," DA's transport spokesperson Ian Ollis told the Mail & Guardian.
Sanral communication head Vusi Mona said this was in fact an administration error where the documents were inadvertently omitted during photocopying.
"Following correspondence received from the DA pointing out the omission of these volumes, we will send the DA the missing volumes. We would like to emphasise that there was nothing sinister with the omission. As a matter of fact these documents were previously given to a trade union federation," said Mona.
Delivery of the documents follows the DA's successful request submitted in June 2013.
The party intends to study the documents, and specifically scrutinise Sanral's monthly financial obligation to the e-toll collection, the collection fees structuring, how transgressors would be prosecuted, as well as an opt-out clause for e-tolling in Gauteng.
Ollis said the DA maintained that e-tolling in Gauteng must be scrapped as it would not benefit the people of the province, and hit the poorest hardest by increasing the price of doing business.
This would result in food price increases and inevitably would undermine economic growth and job creation.
Meanwhile, Sanral is set to spend R85-million this year on advertising its controversial e-tolling plans in Gauteng, according to Transport Minister Dipuo Peters.
"The South African National Roads Agency Limited has a budgeted amount of R85-million ... which will be used for both the alternative sources of funding campaigns as well as corporate campaigns," she said in a written reply to a parliamentary question, tabled on Monday.
An amount of R23.3-million had been spent to date.
Peters was responding to a question – posed by DA MP Ian Ollis – on how much the roads agency "is planning to spend on advertising relating to the e-toll system in Gauteng".
The minister's reply shows the agency's spending on advertising rose sharply after 2009/10. In that year, it spent R6.4-million on "print and broadcasting advertising alternative sources of funding campaign".
In 2010/11, 2011/12, and last year (2012/13), it spent totals of R30.4-million, R84.5-million and R87.1-million respectively on campaigns and advertising. – Additional reporting by Sapa
