How a case moves here
Sun Prairie follows Wisconsin law on arrests, release, and courts; the full set covers prosecutors, defense, and jails too.
- Who decides release first
For most misdemeanors, a police officer or the jail can take cash bail under the statewide misdemeanor bail schedule. For felonies, a circuit court commissioner or circuit judge sets bail at the initial appearance. Wisconsin bars paid bail bondsmen, so sureties must be unpaid people.
Wis. Stat. 969.07Wis. Stat. 969.065Wis. Stat. 969.12Wis. Stat. 757.69(1)(b)Wis. Stat. 968.075(2m), (5)- Time to see a judge
A person who is arrested must be taken before a judge within a reasonable time in the county where the offense is charged. Wisconsin law sets no number of hours.
Wis. Stat. 970.01(1)- Money bail
Wisconsin courts may set cash bail. A surety must be a state resident and an unpaid natural person, so commercial bail bonds are not allowed.
Wis. Stat. 969.12
Read from the statutes and court rules cited, 2026-09-30. Municipal courts are left out of limited_courts because they hear only ordinance forfeiture cases. wispd.org returned errors, so the defense section rests on statute. Whether municipal judges must be lawyers was not checked; it doesn't affect criminal cases.
