An Act relative to administering state and local agreements

This bill requires Massachusetts sheriffs, correctional facilities, and local law enforcement agencies to only perform federal immigration enforcement activities (under 8 U.S.C. § 1357(g)) if the federal government covers all costs, including employee compensation. It mandates that these entities maintain public records of such activities and submit annual reports to specific legislative committees, including the committees on ways and means and public safety. The law also defines key terms like "agreement" and "law enforcement agency" to clarify which state and local entities must comply.
