The Illinois Supreme Court ordered that the suspension involving Allen James begin April 5.
The Attorney Registration and Disciplinary Commission say that James was serving as state's attorney in March 2008 when he committed aggravated assault on a process server who was trying to serve him with a summons in a lawsuit.
During that confrontation, James allegedly displayed a handgun.
A judge in 2011 convicted James of aggravated assault, fined him $1,500, and ordered him to spend a year under supervision and to surrender the handgun.
