Chimaroke Nnamani, former governor of Enugu state is being accused of money laundering.
Mr. Nnamani, now a Senator, is charged alongside Sunday Anyaogu; Rainbownet (Nig) Ltd; Hillgate (Nig) Ltd; Cosmos FM; Capital City Automobile (Nig) Ltd; Renaissance University Teaching Hospital; and Mea Mater Elizabeth High School.
They pleaded not guilty to all the charges.
The accused were first arraigned in 2007 before Justice Abubakar Tijani.
The case was later re-assigned to Justice Charles Archibong, who has now been forced into retirement following the recommendation of the National Judicial Council.
Justice Mohammed Yunusa becomes the third judge to handle the matter.
Ricky Tarfa, a Senior Advocate of Nigeria, pleaded with the judge to allow the accused continue to enjoy the bail terms granted by Mr. Archibong.
Mr. Yunusa acquiesced.
When Mr. Nnamani and his co-accused were arraigned in 2007, Kelvin Uzozie, the prosecutor, said that they laundered various sums of money to the tune of N5 billion believed to be proceeds of crime, lodging the funds in a secret account.
The accused were also alleged to have failed to comply with the lawful inquiry of Ibrahim Lamorde, then Director of Operations of the Economic and Financial Crimes Commission, EFCC.
According to the prosecutor, the alleged offences contravened the provisions of the Money laundering (prohibition) Act, 2004 and the EFCC Act, 2004.
