At an arraignment, the crimes that you are charged with will be formally read aloud in court. In the Illinois Justice System, you will have this hearing no matter what degree of crime you were charged with (misdemeanor or felony). Here is what you should expect to happen at most standard arraignments.
Arraignments should be held within a reasonable time frame, as dictated by the sixth amendment. If an arraignment is set for six months or more after the time of your arrest, your attorney may petition for dismissal.
