Arraignment on the Information (AOI) Definition

An AOI is an acronym for Arraignment on the Information. An AOI is the first hearing on a felony case in a circuit court. At the AOI, the government provides the defendant with a formal charging document identifying the charges in the case.

The charging document is called an Information. The defendant can plead guilty, not guilty, or stand mute to the Information. The term “AOI” is most commonly used in the Wayne County Circuit Court’s Frank Murphy Hall of Justice. Other circuit courts in Michigan refer to the proceeding as a Felony Arraignment.
