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.
