An urgent court application by the Gupta-owned Optimum and Koornfontein coal mines to reclaim rehabilitation funds worth over R1.7bn, has been postponed. The money was seized by the National Prosecuting Authority's (NPA) Asset Forfeiture Unit. Trustees of the rehabilitation funds controlled by the mines approached the North Gauteng High Court on Thursday for the reconsideration of the seizure of the funds. The money is meant to be used to rehabilitate the mines once mining operations have come to an end.The application was opposed by the NPA.The court did not hear the merits of the case. However, Judge Bill Prinsloo did deal with arguments as to whether or not the Organisation Undoing Tax Abuse (OUTA) should be allowed to make submissions on the application. Advocate Mike Hellens, SC, for the Gupta-owned mines, argued that if OUTA wanted to join the proceedings, there was a measure and manner in which it could join. He argued that it couldn't merely make submissions and address the court. "They're either in or not in," said Hellens.Suspicions funds were irregularly usedAdvocate Nazeer Cassim, SC, for the National Director of Public Prosecutions, argued that a sitting judge, in terms of the Constitution, had the power to decide how to run their court and that there was a duty to hear all interested parties to help a court make a judgment.Prinsloo dismissed the objections and ruled that OUTA could make submissions as it had a direct and general interest in the matter."Although there isn't an official joinder application they did in a sense apply to join by making these submissions and explaining why they want to make these submissions," said Prinsloo.READ: Gupta business rescue practitioners shown the door after questioning suspect transactionsThe court then adjourned to allow the different counsels to engage each other. Upon their return, Hellens told the court that all parties involved had agreed to postpone the matter to May 31 and June 1 and that the costs orders are to be reserved.Prinsloo told the court as he summed up the application that the NPA had expressed a concern that the funds in the trusts had been irregularly used.Prinsloo said the preservation order, removing the funds from the trustees and placing them in a Nedbank account, was granted in an ex parte application on March 8.NPA, Hawks 'incompetents'In a statement released on Wednesday evening by BDK Attorneys on behalf of the Gupta family, the NPA was slammed as having an "appalling lack of understanding of commerce and the true nature of even the very legislation that the NPA works within" with respect to the Prevention of Organised Crime Act, which was used to get the preservation order on the trusts."That preservation order will shortly, we are satisfied, be set aside by an equally punishing and disparaging order of court shortly to be presented to court," the statement read."Not only have the Gupta companies and the Guptas been attacked by incompetents in the National Prosecuting Authority and the Hawks, but it is blandly stated by a minister of state, by senior prosecutors and senior police officers," the statement read.
