The Boston Trust Act ordinance of 2014 seeks to limit cooperation by the Boston Police Department with U.S. federal immigration authorities. The Boston City Council approved the original version in August 2014. The ordinance was amended in December 2019.
The 2019 version of the Boston Trust Act ordinance states: "A law enforcement officer shall not detain an individual solely on the basis of a civil immigration detainer request or an ICE administrative warrant after the individual is eligible for release from custody, unless ICE has a criminal warrant, issued by a judicial officer, for the individual." The quoted sentence refers to Boston police officers. "ICE" stands for U.S. Immigration and Customs Enforcement.
