The Judges
Johnson County is coextensive with Kansas's 10th Judicial District (Johnson County alone). Kansas Constitution Art. 3 §6 makes partisan election of district judges the default statewide, with nonpartisan (merit) selection available only where a judicial district's electors have adopted it under K.S.A. 20-2901. Which method the 10th Judicial District actually uses, and current judges' names, were not confirmed from a source reachable in this research pass; district court operations for Johnson County are administered separately from county government at kscourts.gov, which was not fetchable. The 10th Judicial District has adopted the nonpartisan method: a local nominating commission of lawyers and non-lawyers sends the Governor a list of names, the Governor appoints, and the judge then faces retention votes. Kansas districts choose this by ballot under K.S.A. 20-2901; partisan election is the default they opted out of.

Notes on the record
- Johnson County received the deepest research pass in this group given its size. Its Sheriff's Office (jocogov.org/johnson-county-sheriff) clearly names its jail facilities, publishes bed capacity, offers a public inmate/booking roster, and lists a Bonding Information page — four of the ten checks are satisfied. Budget, PREA, inspections, deaths in custody, contracts with other agencies, and a published phone/video/commissary rate schedule were not found on the pages reached; several sub-pages (Mail and Visitation, Sheriff's Records, Inmate Accounts) reference these topics generally but do not publish figures or documents.
- The Johnson County Department of Corrections (JCDOC) is organizationally separate from the Sheriff's Office and runs adult community-corrections programs and juvenile detention, not the main adult jail; this was confirmed by fetching jocogov.org's own pages and is recorded here specifically so it is not confused with the Sheriff's Office Detention Bureau, which runs the county jail.
- State inspection: repealed. K.S.A. 75-5228, Kansas's 1973 adult jail inspection statute, was repealed effective April 11, 1996 (companion K.S.A. 75-5227 repealed effective July 1, 1996); nothing replaced it, and the Kansas Department of Corrections runs no county-jail inspection program — this applies to Johnson County exactly as to every other Kansas county.
- Johnson County is governed by an elected Board of County Commissioners (a chair elected countywide plus six district commissioners) under the county's home-rule charter government; specific member names and the board/minutes pages were not the focus of this research pass's limited search budget and were not confirmed from a fetched source.
These three offices decide who sits in a cell in Johnson 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).
How much is your sheriff — and your judge — costing you?
Your VOTE is POWERFUL.
The sheriff who runs this jail is elected. So are the commissioners who pay for it.
