The Public Protector's application for leave to appeal the scathing Estina dairy farm judgment has been dismissed with costs. Handing down judgment in the Gauteng High Court in Pretoria on Friday, Judge Ronel Tolmay said Busisiwe Mkhwebane failed to make out a case on the merits of the Estina dairy farm judgment and with regard to costs.In August this year, the court handed down the scathing judgment declaring that Mkhwebane had failed the people of South Africa in the way she dealt with the investigation. It set aside Mkhwebane's report on the Vrede dairy project, declaring it "unlawful, unconstitutional and invalid".Tolmay ordered the Public Protector, in her official capacity, to pay 85% of the DA's costs on an attorney scale and 85% of the costs of the Council for the Advancement of the South African Constitution (Casac). Mkhwebane was ordered to personally pay 7.5% of the DA's costs, as well as 7.5% of Casac's.In dismissing the leave to appeal application on Friday, Tolmay said her ruling considered Supreme Court of Appeal judgments and Constitutional Court judgments which had set the parameters for how and why costs orders should be given.Limited in carrying out dutiesRegarding the judgment on the merits, Tolmay noted that the Public Protector had been tasked with investigating the matter again and therefore, in the interest of the public, further resources should not be spent on appealing the merits because the matter was academic.News24 previously reported that the Public Protector argued Tolmay had exercised her judicial discretion too far when granting the personal costs order.Advocate Francois Botes, on behalf of the Public Protector, further argued that his client would be limited in carrying out her constitutional duties objectively should she be under the threat of a personal costs order."The impression that it has created … there is a message to the office of the PP that if she conducts herself in a robust manner in order to give effect to what is provided for in the Constitution … she might be [dealt] costs, and personal costs, under specific circumstances where her approach was bona fide [and] honest," Botes argued at the time.Meanwhile, the DA has welcomed the High Court's dismissal of the leave to appeal application.In a statement after the judgment, the DA's leader of the opposition in the Free State legislature, Roy Jankielsohn, said the ruling "is a victory for the 80 beneficiaries of the project and the people of the Free State who have already been waiting for seven years for redress and justice"."She must now carry out a comprehensive investigation and ensure that her recommendations are in line with her role to ensure justice for the marginalised people in our society and remediate malfeasance in government," said Jankielsohn.
