The Judges
Illinois circuit judges are elected on a partisan ballot and then stand for retention every six years (60% yes needed); associate judges are appointed by the circuit judges. They are state judicial officers, not county officials. Since 18 September 2023 Illinois has no cash bail — judges decide pretrial release or detention at a hearing.

- Phone and video through ICSolutions, commissary through Aramark; no call, video or commissary rates published.
- County finance page and document library opened but no budget document was located, so budget is not counted; countyofkane.org was refused.

These three offices decide who sits in a cell in Kane County and what it costs the people who live here. Nationally, almost 77% of the people who died in local jails in 2019 had not been convicted of anything, and suicide was the leading single cause of those deaths (Bureau of Justice Statistics, Mortality in Local Jails, 2000–2019).
