Johannesburg -

An application by Sanral to keep secret certain tolling documentation is set to be heard in a closed session at the Cape High Court on Monday.

The South African National Roads Agency Limited's application - to ensure that supplementary papers on the proposed N1/N2 Winelands Toll Highway Project not be put on public record - is the latest development in an ongoing legal battle between the parastatal and the City of Cape Town.

In May last year, the municipality was granted an interim interdict to halt the tolling project.

The interdict remains in force until the finalisation of the City's application to have Sanral's declaration of the project and the selection of the preferred bidder, Protea Parkways Consortium (PPC), be reviewed and set aside.

Sanral and PPC now want the matter to be heard in a closed court and to have related court documents kept out of the public domain.

Last week, two non-governmental organisations, the Right2Know Campaign and Section 16, said in a statement that Sanral had previously suggested secrecy was necessary due to “commercial confidentiality”.

Sanral declined to comment on the matter at the time, with spokesman Vusi Mona saying the proceedings were sub judice. - Sapa
