Meetings: Grand jury meetings are held in private. Typically, a prosecutor from the district attorney’s office presents a case through testimony from a law enforcement officer as a witness. When grand juries deliberate and vote on whether to hand up an indictment, no one besides the grand jurors are allowed inside the room.
Service: A grand jury sits for what is called a term of court. In rural counties, that can be for several months. In Fulton County, a term of court is two months in duration. Also in Fulton, two grand juries are selected, with one meeting on Mondays and Tuesdays, the other on Thursdays and Fridays.
Nothing special: Last year, at the request of Fulton County District Attorney Fani Willis, a special purpose grand jury was convened to use its subpoena power to hear testimony and examine documents in the investigation of the attempted overthrow of the 2020 presidential election. The special grand jury heard from almost 75 witnesses and issued a final report, only a part of which has been made public and which recommended multiple people be indicted. But unlike a regular grand jury, the special grand jury cannot issue criminal indictments.
