The accused have denied conspiracy and abuse of office charges arising from the transfer of 12 plots, irregularly excised from the land belonging to the Kenya Airports Authority (KAA).
Charges against former Commissioner of Lands Wilson Gachanja and former KAA managing director Peter Lagat were quashed last year after the court ruled that they had no case to answer.
Mr Kulei is separately charged with obtaining Sh17.9 million through the sale of public land in Mombasa to a private firm, Gas Company Ltd.
According to the prosecution, Mr Kulei obtained Sh12 million from Gas Company Ltd on May 19, 1999 in Nairobi and another Sh5.9 million by falsely pretending that Sian Ltd had paid land rent, rates and assessment fee.
Mr Komen is accused of breach of trust by authorising the payment of Sh65.2 million from KPC to Gas Company.
He is said to have been a signatory on behalf of the KPC, which owned a 45 per cent stake on behalf of the government.
All the companies named had a joint venture but which collapsed before the project kicked off.
