SB 1164 Arizona Senate · 57th Legislature - First Regular Session

immigration laws; local enforcement

Arizona's SB 1164 mandates that local governments (cities, counties) and law enforcement agencies must cooperate with federal immigration enforcement, prohibiting policies that restrict such cooperation. It requires police to honor ICE detainer requests (where ICE claims probable cause a person is deportable), notify judges about detainers, and document them in case files. The bill also allows Arizona's Attorney General to investigate local entities that violate these rules, with cases taking priority in court. The bill passed the legislature but was vetoed by the Governor on April 18, 2025, so it did not become law.

What changed between versions

Introduced Version Senate Engrossed Version · 7 edits · Feb 27, 2025
MODERATE
The bill was reformatted from an introduced draft to a Senate engrossed version, adding new sections to Arizona Revised Statutes that mandate state cooperation with federal immigration enforcement. Key substantive changes include expanding the definition of law enforcement agencies to include the Department of Public Safety and municipal police, requiring all agencies to enter into memoranda of agreement with federal authorities, and establishing new enforcement mechanisms allowing taxpayers to sue if the Attorney General fails to act on immigration compliance issues.
Scope change
The bill now explicitly includes the Department of Public Safety and municipal police departments as law enforcement agencies required to cooperate with federal immigration enforcement, whereas the original draft only listed county sheriff's offices and the State Department of Corrections.
REQUIREMENT

All law enforcement agencies must enter into memoranda of agreement with federal immigration authorities by January 1, 2026, and report quarterly on their status.

Law enforcement agencies must notify judges when individuals are subject to immigration detainers and record this information in case files.

Correctional facilities must enter into agreements with federal immigration authorities for temporary housing of individuals subject to immigration detainers.

At least 10% of law enforcement officers must be trained in accordance with federal immigration memoranda of agreement.

DEFINITION

Expanded the definition of law enforcement agencies to include the Department of Public Safety and municipal police departments in addition to county sheriff's offices and the State Department of Corrections.

ENFORCEMENT

New provisions allow taxpayers to request the Attorney General to take legal action against non-compliant agencies, and if the Attorney General fails to act within 60 days, taxpayers can file their own lawsuits.

TIMELINE

The act applies retroactively to December 31, 2024, and requires agencies to begin notifying state officials about their immigration cooperation status by October 1, 2025.
