Outa might have to drop its court challenge to implementation of e-tolling on Gauteng's highways if it does not raise an extra R1 million in three weeks, chairman Wayne Duvenhage said on Wednesday.
"There is a very real chance if we do not get this money this matter will not be heard," Duvenhage said at a press conference to appeal for the money.
The Opposition to Urban Tolling Alliance (Outa) had until June 21 to raise the money.
It had so far raised R8.4 million through donations and still owed about R3m in legal fees. Without the R1m payment to advocates, the case could not go ahead.
The lawyers had donated much of their services, but still had some costs they could not cover themselves in what was a technical case, said Duvenhage.
Outa has led a court challenge to the introduction of e-tolling, funding it through donations.
In April, roads agency Sanral said it would begin e-tolling on Gauteng roads within two months.
Last April, the High Court in Pretoria granted Outa an interdict approving a full judicial review before electronic tolling could be implemented.
The interdict prevented Sanral from levying or collecting e-tolls pending the outcome of the review. Sanral and the National Treasury appealed the court order.
In September, the Constitutional Court set aside the interim order. In December, the High Court in Pretoria dismissed Outa's application to scrap e-tolling.
The court granted Outa leave on January 25 to take the matter to the Supreme Court of Appeal in Bloemfontein. The appeal is expected to be heard on September 25 and 26. -Sapa
