The Superior Court of Cook County was a court in Cook County, Illinois.
It was preceded by earlier courts. 1845 saw the creation of the County Court of Cook County.[1] In 1849, this was renamed The Cook County Court of Common Pleas.[1] In 1859, this was continued as the newly-founded The Superior Court of Chicago. In 1870, this was formally continued as the Superior Court of Cook County, which was created by the newly-adopted Constitution of Illinois.[1][2]
The Superior Court of Cook County, and its predecessor courts, held roughly the same jurisdiction as the original Circuit Court of Cook County.[1][3][4]
The court ceased to exist in 1964 after an amendment to the Constitution of Illinois took effect, creating of the modern Circuit Court of Cook County, unifying Cook County's court system.[2]
