(Reuters) - A U.S. appeals court on Monday struck down California's ban on privately-run immigrant detention centers in a challenge brought by private prison operator GEO Group Inc and the Biden administration.
The San Francisco-based 9th U.S. Circuit Court of Appeals said California's 2019 ban gave the state too much control over how the federal government handles immigrant detainees.
A federal judge in San Diego had upheld the state law in 2020, ruling that California could prohibit private detention centers because federal law does not explicitly allow for them.
The 9th Circuit, in an 8-3 decision, said the government has come to rely almost exclusively on detention centers operated by GEO Group and other companies. California, the largest U.S. state, does not have the authority to second-guess that decision, the court said.
About 80% of immigrants awaiting deportation hearings are held in private facilities, according to the American Civil Liberties Union and other advocacy groups. Most are operated by GEO Group and rival CoreCivic Inc, but dozens are owned by smaller companies.
The California Attorney General's office, GEO Group, and the U.S. Department of Justice did not immediately respond to requests for comment. The state could ask the U.S. Supreme Court to take up the case.
Immigrant advocates have said private facilities often are overcrowded and understaffed, subjecting detainees to inhumane conditions.
While campaigning for the 2020 election, Biden said he wanted to end the use of private detention centers to house immigrants. But Biden did not mention the detention of immigrants in a 2021 executive order limiting the federal government's reliance on private criminal prisons, which drew criticism from advocacy groups.
California's law prohibits the operation of any private detention facilities in the state, including prisons, but the lawsuits only challenged the ban on immigrant detention centers.
The dissenting 9th Circuit judges on Monday said the law should be upheld because it applies to private companies such as GEO Group and only indirectly regulates the federal government.
