Assembly Bill 739 aims to prohibit state and local government officials, including law enforcement officers, from assisting in the detention of individuals solely based on their immigration status. Specifically, the bill states that no official, employee, or agent of a state agency or local governmental unit may aid in such detentions. However, it allows for the provision of access to facilities as required by a properly executed judicial warrant. This measure is intended to limit the involvement of state and local entities in federal immigration enforcement.

Additionally, the bill prohibits state agencies and local governmental units from entering into or continuing existing agreements with the federal government under section 287(g) of the federal Immigration and Nationality Act, which allows for certain immigration enforcement activities to be performed by state and local officials. By creating section 20.932 of the statutes, the bill establishes clear prohibitions against these practices, reinforcing the separation between state and federal immigration enforcement responsibilities.
