The proposed bill introduces a new chapter, CHAPTER 167, titled "Detention for Federal Civil Immigration Violations," into Title 42 of the General Laws. It prohibits state and municipal officials or agencies from entering into or renewing any agreements to detain individuals for federal civil immigration violations. Additionally, any existing contracts related to such detentions must be terminated by July 1, 2026. The bill also outlines specific prohibitions against using public resources, including funds and property, to facilitate the establishment or operation of facilities that detain individuals for these violations.

Furthermore, the bill prohibits receiving payments related to the detention of individuals for federal civil immigration violations and mandates that no laws or policies conflicting with its provisions can be imposed or continued. The act includes a severability clause, ensuring that if any part of the chapter is deemed unconstitutional, the remainder will still be valid. This legislation is set to take effect upon passage.
