While California awaits a final decision on the legality of its ban on holding immigrants in private prisons, a federal appeals court ruled Friday that migrants can sue a major operator of those prisons for making them work for little or no pay to clean restrooms and kitchens and take out the trash. The class-action suit was filed in 2017 by two former inmates of California prisons owned by CoreCivic, which has contracts with U.S. Immigration and Customs Enforcement to hold immigrants while awaiting deportation hearings.
