AB 85 adds Section 7282.7 to the California Government Code and replaces local discretion with a mandatory duty to cooperate with federal immigration authorities for people convicted of a felony. Specifically, the bill requires local law enforcement to provide release dates, transfer individuals on request, and detain on hold requests from immigration authorities.
The change narrows the prior statutory limits that allowed law enforcement to decline cooperation in many cases and raises practical and legal questions for counties and municipal police: it increases potential detention time, creates predictable operational costs, and exposes local agencies to possible legal challenges over warrantless holds and state-federal coordination.
At a Glance
What It Does
The bill requires law enforcement to comply with immigration requests by (1) providing release-date information, (2) transferring custody upon request, and (3) detaining individuals on immigration hold requests. The duty applies whenever the person has a felony conviction.
Who It Affects
County sheriffs, city police departments, and detention facilities that currently exercise discretion over ICE/immigration detainers. Federal immigration authorities (as defined by Section 7284.4(c)) receive broader access to custody and scheduling information.
Why It Matters
The bill replaces discretionary noncooperation rules with a clear mandatory standard tied to a felony conviction, shifting costs and legal risk from the federal government onto local agencies and changing how California balances local autonomy, public-safety priorities, and immigrant rights.

What This Bill Actually Does
AB 85 rewrites the cooperation rules between California local law enforcement and federal immigration authorities. Instead of allowing officers to exercise discretion under existing statutes, the bill imposes a mandatory duty: if someone has a felony conviction, local law enforcement must provide release-date notifications, transfer custody when asked, and detain the person in response to an immigration hold request.
The command is phrased as "shall," converting permissive practices into enforceable obligations.
The bill explicitly displaces two earlier statutory constraints—Sections 7282.5 and 7284.6—that governed when local agencies could assist immigration authorities. It does not create new criminal penalties for noncompliance in the text, but it designates the requirement as a state-mandated local program, triggering the Commission on State Mandates' reimbursement process if costs are found.
AB 85 also imports the definition of "immigration authorities" by reference to Section 7284.4(c), so the federal entities covered mirror that prior statutory cross-reference.Operationally, the mandate affects several discrete practices: jail intake and release procedures (to capture and disclose release dates), custody-transfer protocols (logistics, transport, paperwork), and detention authority (holding someone on a federal request). The bill's plain language leaves several implementation details unresolved—most notably the precise timing and scope of permissible additional detention, whether convictions must be final or from any jurisdiction, and how agencies should reconcile conflicting legal duties when a hold request would exceed lawful custody periods.
Those gaps will matter for county administrators, counsel, and sheriffs as they translate the statute into daily booking and release workflows.
The Five Things You Need to Know
The bill adds Government Code Section 7282.7 and uses mandatory language: local law enforcement "shall" provide release dates, transfer custody, and detain on hold requests from immigration authorities.
The duty applies to any individual who has been convicted of a felony—there is no narrowing to "serious" or "violent" felonies as in some prior rules.
AB 85 expressly operates "notwithstanding" Sections 7282.5 and 7284.6, removing those statutes' discretion-based limits on cooperation where a felony conviction exists.
The term "immigration authorities" is incorporated by reference to Section 7284.4(c), aligning the bill's covered federal actors with an existing statutory definition.
The bill labels the requirement a state-mandated local program and triggers the Commission on State Mandates reimbursement process if the Commission finds state-mandated costs.
Section-by-Section Breakdown
Every bill we cover gets an analysis of its key sections.
Mandatory cooperation actions (release dates, transfers, holds)
This subsection lists three distinct affirmative duties: provide release-date information upon request, transfer custody to immigration authorities when requested, and detain an individual based on an immigration hold request. Practically, each duty targets a different operational function—information-sharing, interagency transfer logistics, and continued detention—and the "shall" language converts previously discretionary acts into mandatory procedures. Agencies will need to adjust intake, recordkeeping, and transport protocols to ensure compliance.
Scope: felony conviction as the sole threshold
Subdivision (b) makes the cooperation requirement apply to any person "who has been convicted of a felony." That is a broader trigger than many prior limits that required specified categories of serious or violent crimes. The statutory silence on whether the conviction must be final, whether it includes convictions from other states or federal courts, or whether it includes juvenile adjudications creates ambiguity that agencies must resolve—likely through policies, interagency agreements, or litigation.
Definition linkage for "immigration authorities"
Rather than define the term anew, the bill cross-references subdivision (c) of Section 7284.4 for the meaning of "immigration authorities." That choice ties the bill to an existing statutory roster of federal actors (e.g., ICE) and avoids drafting inconsistencies, but it also imports whatever limitations or scope are in that provision—so a change to 7284.4(c) elsewhere would alter AB 85's coverage.
State-mandated local program and reimbursement carve-out
Section 2 instructs that, if the Commission on State Mandates finds AB 85 imposes costs on local agencies, reimbursement is to follow the standard statutory process (Part 7, Division 4 of Title 2). The provision does not itself provide funds; it only commits to the existing reimbursement mechanism, leaving the timing and sufficiency of any compensation to the Commission's findings and the Legislature's subsequent actions.

Every bill creates winners and losers. Here's who stands to gain and who bears the cost.
Who Benefits
- Federal immigration enforcement agencies (e.g., ICE) — gain mandatory access to custody and scheduling information and can expect more reliable transfers of individuals with felony convictions.
- Prosecutors and law enforcement seeking removal of noncitizen felony offenders — benefit from a predictable legal obligation that facilitates post-conviction transfers to federal custody.
- Victims and victim-advocacy groups focused on removal of convicted noncitizen offenders — may see faster transfers and reduced opportunity for release back into the community.
Who Bears the Cost
- County sheriffs and municipal police departments — must change intake/release processes, detain individuals longer in response to holds, coordinate transfers, and absorb staffing and transportation costs unless reimbursed.
- County jails and detention facilities — face increased bed occupancy and scheduling complications from holds that may extend custody beyond planned release, with associated daily costs.
- Local governments and taxpayers — carry fiscal risk if the Commission on State Mandates does not find reimbursement adequate or if reimbursement is delayed, shifting costs to county budgets and services.
- Noncitizen individuals with felony convictions — face mandatory detention/transfer outcomes that reduce local discretion and may accelerate removal proceedings, with legal and liberty consequences.
Key Issues
The Core Tension
The bill pits a state interest in uniform, mandatory cooperation with federal immigration enforcement and the goal of removing convicted felons against local governments' interest in retaining discretion to manage custody, limit fiscal burden, and avoid constitutional exposure—forcing a choice between operational predictability for federal partners and local control over policing and detention practices.
AB 85 stitches a bright-line rule into a statutory framework that previously left substantial discretion to local agencies. That clarity can simplify expectations, but it also removes buffers that counties used to balance constitutional limits, resource constraints, and community trust considerations.
The bill does not address important operational contours: it doesn't say whether a conviction must be final or how to handle convictions from other jurisdictions; it does not set maximum periods for detention on a federal hold; and it does not create an enforcement mechanism within state law for noncompliance beyond the state-mandate/reimbursement machinery.
The fiscal side is uncertain. Labeling the requirement a state-mandated local program triggers the Commission on State Mandates, but past experience shows that Commission findings, legislative appropriations, and the timing of reimbursements can be unpredictable—leaving counties to front costs.
Finally, the mandatory holding language raises potential Fourth Amendment and statutory-liability questions. Courts have found some types of warrantless detentions based solely on federal detainers unlawful; the bill's command to detain on hold requests could expose agencies to litigation unless local protocols add probable cause or warrant safeguards.
