This bill aims to restrict the use of State, county, and municipal resources in support of immigrant detention facilities. It explicitly prohibits the State and its political subdivisions from expending funds to construct, renovate, or repurpose properties for use as immigrant detention facilities. Additionally, it forbids the sale, donation, or leasing of such properties to any entity for this purpose. The bill also prevents any financial assistance related to the costs of privately-owned immigrant detention facilities, including payments for the detention of individuals in facilities that are partially owned by private entities.

Despite these restrictions, the bill allows for the provision of health and safety resources to individuals detained in these facilities. It defines "political subdivision" as any unit or agency of government that derives its authority from the State of New Jersey, which includes counties and municipalities. The act is set to take effect immediately upon passage.
