Immigration laws; local enforcement
SB1164, titled the Arizona Immigration, Cooperation and Enforcement Act or the Arizona ICE Act, would require and facilitate greater cooperation between Arizona state and local agencies and federal immigration authorities. The bill authorizes state, county, city, town, and other political subdivision officials to enter into memorandums of agreement with federal agencies, including under federal programs such as 8 U.S.C. § 1357(g), for immigration enforcement. It also prohibits state and local policies that restrict cooperation with federal immigration authorities and directs agencies to consider federal incentive programs and grant funding to support such cooperation.
The bill imposes specific duties on law enforcement agencies that hold people subject to ICE detainer requests. Those agencies would have to notify the judge handling bail, record the detainer in the case file, honor qualifying detainer requests, and inform the person being held. The bill defines when a detainer request is facially sufficient and provides exceptions for people who prove U.S. citizenship or lawful status, or where another agency has already completed the required notice and recording steps. It also requires correctional facilities under the Department of Corrections or county sheriffs to enter agreements with ICE for temporary housing and reimbursement of detention costs.
SB1164 would also create enforcement mechanisms. The attorney general could sue to compel compliance with the new immigration-cooperation requirements, and taxpayers could ask the attorney general to act and, after 60 days, bring suit themselves if the attorney general does not. The bill includes legislative findings asserting that illegal immigration has increased, that it poses public safety and fiscal burdens, and that Arizona should use available federal resources and pursue federal reimbursement for immigration-related costs. It applies retroactively to December 31, 2024, and contains a severability clause.
The bill’s impact on state law would be significant because it adds new statutory duties for local law enforcement, county sheriffs, the Department of Corrections, judges, and the attorney general, while limiting local policies that reduce cooperation with federal immigration enforcement. It also expands the state’s role in immigration-related detention and intergovernmental agreements and creates a private-enforcement pathway through taxpayer lawsuits. In practical terms, it would likely increase coordination with ICE and potentially increase detention-related administrative and housing obligations for local and state facilities.
The general sentiment reflected in the voting history is supportive but divided. The bill advanced through both chambers with majority Republican support, passing key committee and floor votes, but several committee votes were close and party-line or near party-line, indicating substantial opposition. The main point of contention is the extent to which the state should compel local agencies to cooperate with federal immigration authorities and whether the bill intrudes on local discretion, imposes unfunded operational burdens, or raises concerns about detainer practices and civil liberties. Supporters appear to view it as a public safety and border-enforcement measure, while opponents likely object to mandatory cooperation, detention obligations, and the enforcement structure.
SB1164 amends Title 11 of the Arizona Revised Statutes by adding new sections governing immigration enforcement cooperation, ICE detainer handling, correctional-facility agreements, and enforcement actions. It affects county sheriffs, municipal police departments, the Department of Corrections, judges handling bail, the attorney general, and taxpayers who may seek enforcement. The bill also creates new obligations to enter ICE agreements, honor qualifying detainers, and preserve records, while restricting local policies that limit cooperation with federal immigration authorities.
The bill appears to have strong support among sponsors and majority-party lawmakers who framed it as a public safety, border security, and fiscal responsibility measure. At the same time, the close committee votes and split floor votes suggest meaningful opposition, likely centered on concerns about local control, detention practices, and the scope of state mandates. Overall, the sentiment is polarized rather than bipartisan.
The main contention is whether Arizona should require state and local agencies to actively cooperate with federal immigration enforcement and ICE detainers, rather than leaving those decisions to local discretion. Critics are likely to focus on mandatory detention-related duties, the possibility of holding people based on federal requests, the bill’s private enforcement provisions allowing taxpayer suits, and the potential costs to local agencies and correctional facilities. Supporters emphasize public safety, compliance with federal law, and reimbursement of immigration-related costs.
