Bobby Ferguson has filed a motion for judgment of acquittal or a new trial after being convicted on multiple federal corruption charges.
Ferguson has been in prison since the convictions in March. The judge has denied him bond. His request for a new trial was filed on Friday.
Former Detroit mayor Kwame Kilpatrick and Ferguson, a contractor with the city, could face up to 20 years in prison for their racketeering convictions alone. A jury found Ferguson guilty on 9 of 11 corruption counts.
Kilpatrick was found guilty on 24 of 30 counts. His father and fellow defendant, Bernard Kilpatrick, faced four counts and was found guilty on the sole count of subscribing to a false tax return in 2005.
