Johannesburg - The DA's call for access to e-toll documents was "surprising" as they were available on Sanral's website, it said on Friday.
"We are surprised by the Democratic Alliance's frantic search for documents which are publicly available and which the DA was invited to make copies thereof," SA National Roads Agency Limited (Sanral) spokesperson Vusi Mona said in a statement.
The DA said on Thursday it was seeking documentation of the contract for services between Sanral, the Austrian company Kapsch TrafficCom, and the Electronic Toll Collection (ETC) joint venture.
DA MP Ian Ollis said this would be done under the Promotion of Access to Information Act.
Kapsch TrafficCom announced on Tuesday that it would get an annual revenue boost of more than €50m (about R669m) for eight years from e-tolling, including operational costs and selling the system hardware and software to Sanral.
According to Mona, the documents in question were published on Sanral's website "and the agency has said so on numerous occasions in the past."
"Why does the DA now feel the need to waste valuable time and start another mischievous campaign to gain documents which are available to them and the public?" he asked.
He said the DA had previously applied for access to information, and Sanral had met DA Gauteng caucus leader Jack Bloom and had shown him "voluminous documents" relating to the project.
"He was invited to choose and make copies of whatever specific documents the DA was looking for. No further correspondence was received from the DA regarding this application."
Ollis and Bloom were not available for comment.
