An Act relative to state compliance with detainer requests

This bill requires Massachusetts state and local law enforcement agencies to comply with U.S. Immigration and Customs Enforcement (ICE) detainer requests. It mandates that agencies notify ICE at least 24 hours before releasing an individual subject to a detainer or hold them for up to 48 hours, and prohibits agencies from having policies that refuse such requests. The law also requires all law enforcement officials to complete training on detainer procedures within six months and mandates annual reports detailing how many detainers were honored, with reasons for any non-compliance. The bill directly affects all state, municipal, and campus police departments, sheriffs' offices, courts, and correctional facilities in Massachusetts.
