The leader of Tonga's opposition, Akilisa Pohiva, has relaunched legal action in the Supreme Court against the prime minister Lord Tu'ivakano, the justice minister Clive Edwards, Princess Pilolevu Tuita and the Tongasat Company.
Earlier a case against the three and the company, alleging theft, conspiracy of theft, embezzlement and conspiracy to commit theft, was dismissed by the Magistrate's Court for insufficient evidence.
But Radio Tonga reports Mr Pohiva was not satisfied with that ruling so he took the matter to the higher court.
He has told the court more than half a million US dollars was given to Tongasat in secret and that amounts to theft and embezzlement.
