Immigration and Customs Enforcement placed an immigration detainer on Sierra on Saturday.

The Massachusetts Supreme Judicial Court, for example, explained that “Massachusetts law provides no authority” for its officers “to arrest and hold an individual solely on the basis of a Federal civil immigration detainer.”

German Hurtado of the Professional Standards Bureau said that the department had not complied with any of the 631 “detainer” requests it had received last year from federal authorities to hold undocumented immigrants for possible deportation.

Known as unlawful detainer cases, evictions today go through the Superior Court’s Ex Parte and Probate Department, where cases are heard by commissioners — attorneys who work under the direction of a judge to hear certain types of cases.

A year later, the agency filed an unlawful detainer in Los Angeles County Superior Court to evict Apex and seek back rent.
