Kidd also signed an agreement which not only indemnified van Heeren against any future claims by his former business partner but also said subsequent disputes had to be settled in South African courts.
In 1996, Kidd sued van Heeren for half of his New Zealand assets. In a 1997 ruling, Justice Robert Smellie said both agreements Kidd signed were an absolute defence against his claims in New Zealand but that the South African courts must decide if the documents Kidd signed meant he had no case. The matter was heard in a South African High Court in 2013 and the judge ruled the documents were void. Van Heeren failed to get leave to appeal the South African case.
"It would be unjust to deny Mr Kidd the fruits of his success in the South African proceeding where the partnership and assets issues were squarely in issue, as Mr van Heeren well knew," Court of Appeal Justices Rhys Harrison, Forrest Miller and Mark Cooper said in their judgment. "There was nothing to prevent him calling evidence in relation to any of the issues he now says he wishes to contest."
The Court of Appeal bench said it saw no basis for disturbing Justice Fogarty's payment order, and ordered van Heeren to pay Kidd's costs.
"As Justice Fogarty found, it is unlikely that Mr van Heeren will be able to displace the presumption that the partnership anticipated equal sharing in the profits," the judges said. "Finally, because the order for payment of US$25 million was conservative, we think it unlikely that it would need to be disturbed in the event that the mutual accounting process proves Mr Browning's estimate wrong."
In a further judgment from the High Court in October 2015, where an application for stay from van Heeren was dismissed, Justice Fogarty said both counsel indicated it was likely that whoever lost in the Court of Appeal would seek leave to appeal to the Supreme Court, leaving the process capable of going "well into 2017."
