Generally, no — federal and state courts in Chicago (and virtually everywhere in the U.S.) do not hold regular court sessions on Sundays. Here’s the breakdown:
Standard Court Operations
Cook County Circuit Court (Illinois state courts in Chicago) operates Monday–Friday during standard business hours, excluding federal/state holidays.
U.S. District Court for the Northern District of Illinois (federal court in Chicago) follows the same Monday–Friday schedule.
Sundays, along with Saturdays, are non-judicial days by default in nearly all court rules.
Exceptions Where Sunday Court Activity Can Happen
Emergency Orders — Judges can issue emergency rulings (like restraining orders) on weekends in urgent situations, sometimes handled by an on-call/duty judge.
Bond Hearings — Cook County has weekend bond court for people arrested, since the law requires a prompt appearance before a judge (typically within 24-48 hours). These often happen daily, including Sundays.
Specific Statutory Deadlines — Certain time-sensitive matters (like emergency child custody or protective orders) may have special weekend procedures.
Bottom Line
If you’re asking because you have a case or hearing scheduled, it’s very unlikely to be on a Sunday unless it falls under one of the emergency categories above.
I should note: I’m not a lawyer, and court procedures can have nuances based on your specific case type. If you have an actual case or upcoming hearing, I’d recommend checking your court notice/summons for the exact date, or contacting the Clerk of the Circuit Court of Cook County directly to confirm.
