The judge had earlier granted them bails.
Justice Mohammed Idris adjourned the case to September 27 for adoption of written addresses.
The accused were charged with conspiring to siphon and launder N4.7 billion from the coffers of Oyo State Government.
The EFCC also accused them of converting N1.9 billion belonging to the state for their personal use through the account of a company known as Heritage Apartments Ltd.@TRIOTINAIJA
