In considering a challenge to a Wisconsin law that requires some sex offenders to wear a GPS ankle monitor for life, the U.S. Court of Appeals for the Seventh Circuit looked to a similar opinion in 2016 which held that the state’s interest in protection and deterring recidivism outweighs an offenders’ “diminished expectation of privacy.”

Three plaintiffs who are repeat sex offenders—Benjamin Braam, Alton Antrim and Dan Olszewski—claim Wisconsin Statute § 301.48, which requires lifetime monitoring for sex offenders who have been convicted on two or more occasions, violates the Fourth Amendment’s reasonableness standard. They filed a lawsuit against Kevin Carr, secretary of the Wisconsin Department of Corrections, in the U.S. District Court for the Eastern District of Wisconsin and moved for a preliminary injunction.
