issue a detainer requesting a state or local jurisdiction to hold a suspected non-citizen for an additional 48 hours beyond their scheduled release. Although the detainer lapses after 48 hours, and there is no longer legal authority to detain the prisoner, this is frequently disregarded, and attorneys across the United States report that non-citizens are frequently held much longer. In the 2014 case Miranda-Olivares v. Clackamas County, United States magistrate judge Janice M. Stewart of the United States District Court for the District of Oregon ruled that immigration detainers violate detainees' Fourth Amendment rights and are merely requests that are not legally binding. In July 2017, the Massachusetts Supreme Judicial Court unanimously held that the commonwealth's law enforcement could not hold a prisoner solely on the authority of an ICE detainer.
