AB 739: Relating to: prohibitions concerning state or local government assistance with federal immigration enforcement.

AB 739 prohibits state and local government agencies, including law enforcement, from detaining individuals solely based on their immigration status. It specifically bans officials from aiding federal immigration enforcement efforts that target people for being undocumented, while allowing access to facilities under valid judicial warrants. The bill also prohibits state or local governments from entering into or continuing agreements with the federal government that enable local police to enforce federal immigration law (such as 8 USC 1357(g) agreements). This directly affects all state agencies, local governments, and law enforcement entities in the state by restricting their cooperation with federal immigration enforcement. The law creates new restrictions on state and local actions, not on federal policies.

It also bans state or local funding for immigrant detention facilities.

It also bans the use of state funds for such detentions and explicitly allows cooperation only when required by a valid judicial warrant. The bill directly affects state agencies, local governments, and facilities providing essential services by restricting their involvement in immigration enforcement actions. Key provisions create clear boundaries for state/local entities to avoid complicity in immigration detentions without court authorization.

SB 484: Relating to: prohibitions concerning use of state and local facilities to detain individuals on the basis of immigration status.

SB 484 prohibits state and local governments from using public facilities (like jails or detention centers) to detain people solely based on their immigration status. It also bans state or local funding from being used to establish or operate immigrant detention facilities. This directly affects cities, counties, sheriffs' offices, and state agencies that manage public facilities or funds. The bill prevents local governments from participating in immigration enforcement through detention or funding, while allowing detention for other legal reasons.

AB 24: Relating to: county sheriff assistance with certain federal immigration functions. (FE)

AB 24 requires Wisconsin county sheriffs to verify the immigration status of individuals jailed for felony offenses by requesting specific documentation (such as passports, birth records, or immigration documents) to confirm lawful presence in the U.S. If verification fails, sheriffs must notify federal Homeland Security and comply with federal detainer requests. Sheriffs must annually report compliance and maintain records of individuals found unlawfully present, with data shared with the state justice department. Counties failing to comply face a 15% reduction in state funding for the following year. The bill directly affects felony inmates, sheriffs, and state-local funding relationships.
