Mr Kulei, Ashar Limited, Sian Enterprises and Agrid Limited, former KPC boss Ezekiel Komen and Mr Prakash Bhundia are accused of conspiracy to defraud a State corporation of Sh65,272,727 in 1999.
Mr Kulei is separately charged with obtaining Sh17.9 million through the sale of public land in Mombasa to a private firm.
A witness Thursday told a Nairobi court that part of payments made by a State corporation were traced to an account belonging to former President Daniel Moi’s aide Joshua Kulei.
Testifying before Senior Principal Magistrate Felix Kombo, Mr David Kang’ara, an investigating officer, said he obtained information from a bank where Kenya Pipeline Company (KPC) held an account.
