Massachusetts police do not have the authority to detain illegal immigrants solely to buy time for federal law enforcement officials to take them into custody, the state's top court ruled on Monday.
The decision amounts to a rejection of requests by the federal Immigration and Customs Enforcement agency for courts and law enforcement agencies to hold illegal immigrants, who are facing civil deportation orders, in custody for up to 48 hours after their cases are resolved.
The Supreme Judicial Court ruled that doing so amounts to a fresh arrest of the person that is not authorized by state law, in the first such ruling to apply to an entire state, according to Massachusetts' attorney general.
"Massachusetts law provides no authority for Massachusetts court officers to arrest and hold an individual solely on the basis of a Federal civil immigration detainer, beyond the time that the individual would otherwise be entitled to be released from State custody," the court wrote in its decision.
