SB 957 California Senate · 2025-2026 Regular Session

Civil detention facilities.

Summary
Existing law requires the operator of a private detention facility, as defined, to comply with, and adhere to, the detention standards of care and confinement agreed upon in the facility's contract for operations, as specified. Existing law requires a private detention facility operator to comply with, and adhere to, all local and state public health orders and occupational safety and health regulations. This bill, the Protecting Vulnerable Immigrant Detainees Model Act, would require the Attorney General, on or before December 31, 2027, to submit to the Legislature a report including a proposed oversight plan for private civil detention facilities that protects the health, safety, and welfare of persons detained in those facilities, as specified. The bill would require the Governor to direct the appropriate state entity to cooperate with the Attorney General for the purposes of developing the oversight plan, as specified. The bill would make related findings and declarations. Existing constitutional provisions require that a statute that limits the right of access to the meetings of public bodies or the writings of public officials and agencies be adopted with findings demonstrating the interest protected by the limitation and the need for protecting that interest. This bill would make legislative findings to that effect.

MODERATE
The August 25 amendment completely removed the social media privacy provisions (the 'Stopping Harmful Information Exploitation and Lawless Data Sharing Act') from SB 957, leaving only the civil detention facilities oversight plan requirement. The bill now solely requires the Attorney General to submit a report including a proposed oversight plan for private civil detention facilities by December 31, 2027. Minor wording changes were also made to the remaining detention facility text.
SCOPE

The entire 'Stopping Harmful Information Exploitation and Lawless Data Sharing Act' (Chapter 31.7, Section 22946.5 of the Business and Professions Code) was removed. This had required social media companies to notify individuals when their personal information was requested via administrative subpoena, provide at least 30 days to challenge the subpoena, determine whether the subpoena was invalid (too broad, irrelevant, procedurally improper), notify the Attorney General within five business days of responding, and prohibited responding while a legal challenge was pending.

In Section 153001(a)(3), the oversight plan requirements now specifically reference 'private civil detention facilities' rather than just 'civil detention facilities,' narrowing the scope of comparable facilities to those that are privately operated.

REQUIREMENT

In Section 153001(a)(1), the requirement changed from submitting 'a proposed oversight plan' to submitting 'a report including a proposed oversight plan,' broadening the deliverable beyond just the plan itself.

DEFINITION

In legislative finding (e) of Section 153000, the text changed from 'While other civil and correctional facilities across the state have oversight mechanisms' to 'While other most civil and correctional facilities across the state have oversight mechanisms,' adding the word 'most' to acknowledge that not all such facilities currently have oversight.
