St. Clair County, Illinois
DUI in St. Clair County: one circuit court, five city guides.
A DUI stop in Belleville, O'Fallon, Fairview Heights, Shiloh, or Swansea is charged in the county where it happens and heard at the St. Clair County Courthouse in Belleville (20th Judicial Circuit). The Illinois Secretary of State imposes the statutory summary suspension, which is challenged in that same court. Start with the shared county path below, then open your city guide for local records and contacts.
Shared county path
How a St. Clair County DUI case usually starts.
The town changes the police agency and records office. The court and license path stays county- and state-level.
Confirm the county and court date
An Illinois DUI is charged in the county where the offense occurred and heard in that county's circuit court. For these five cities that is the St. Clair County Courthouse in Belleville (20th Judicial Circuit). Confirm the county, date, and courtroom printed on your citation or bond paperwork.
Know when the summary suspension begins
The Secretary of State imposes a statutory summary suspension that begins on the 46th day after notice. It is challenged by a petition to rescind filed in the same circuit court as the DUI case (625 ILCS 5/2-118.1), which sets its own hearing timing, so act quickly.
Gather documents before consultations
Collect the citation, bond or release paperwork, the law-enforcement sworn report, and any chemical-test or refusal records. Each city guide includes a document checklist and the local police records contact.

How license consequences work in Illinois.
The Secretary of State imposes the suspension
The statutory summary suspension is an administrative action by the Illinois Secretary of State that begins on the 46th day after notice, commonly 6 months for a failed test or 12 months for a refusal on a first offense.
It is challenged in the same court as the DUI
A petition to rescind the summary suspension is filed in the same circuit court handling the DUI case, not a separate forum (625 ILCS 5/2-118.1).
