Shares a universe with other shows created by Dick Wolf: Law & Order: Special Victims Unit (1999), Chicago Fire (2012), Chicago P.D. (2014), and Chicago Med (2015). This means that sometimes characters of Chicago Justice appear on his other shows and its story continues there or vice versa. One of the characters of this show is Antonio Dawson, who was introduced as a recurring character on Chicago Fire, and then became a main character on Chicago P.D. before moving over to this show.

Prosecutor Peter Stone is the son of Ben Stone, the original lead prosecutor on Law & Order (1990), which was set in New York. The series is set in the same universe as Law and Order, as the companion series Chicago P.D. (2014) had crossed over with Law & Order: Special Victims Unit (1999).

Cancelled by NBC after one season as of May 2017, making it the shortest-lived of the Chicago series.

Originally introduced as a backdoor pilot in Chicago P.D.: Justice (2016), which aired in May 2016.
