Arizona immigration law beats first court challenge

Arizona immigration law cleared an initial obstacle on Friday when a federal judge declined to grant an emergency order blocking enforcement of a voter-approved measure that criminalizes “illegal entry from a foreign nation” under state law.

U.S. District Judge Michael T. Liburdi denied a temporary restraining order sought by the Florence Immigration and Refugee Rights Program, a nonprofit that offers free legal services to detained migrants. The judge found the organization had not shown it has standing to sue over the ballot initiative, which Arizona voters approved in 2024 with 62% support and is now codified as A.R.S. 13-4295.

During a two-hour hearing in Phoenix, Liburdi, a Donald Trump appointee, expressed skepticism about the nonprofit’s theory of harm. He questioned whether potential increases in the group’s expenses, such as travel and staffing to handle cases in both state and federal systems, were enough to block a law approved by voters. He said the record did not show concrete harm because no migrants have been processed under the new state system yet, and section 5 of the measure applies prospectively.

Arizona immigration law faces standing and supremacy clause claims

The Florence Project challenged section 5 of Proposition 314 under the U.S. Constitution’s supremacy clause, arguing Arizona cannot create a parallel immigration scheme that authorizes state judges to order deportations. Staff attorney Kathryn Huddleston told the court the law would force the nonprofit to divert resources and would impede its ability to serve people detained under the state regime, which does not include exceptions for asylum seekers or others eligible for humanitarian protections under federal law.

Liburdi concluded those concerns were too speculative at this stage. He said any extra expenditures did not amount to interference with the group’s core activities and that there was no demonstrated harm to existing clients.

Enforcement of the Arizona measure had been on hold pending a ruling by the U.S. Court of Appeals for the Fifth Circuit on Texas’ Senate Bill 4, which contains similar provisions. Sixty days after the Fifth Circuit reversed an order blocking the Texas law, Arizona’s statute took effect.

Scope of the law and competing arguments

Proposition 314 authorizes local and state officers to arrest people who cross the border outside official ports of entry. It bars immigrants without permanent legal status from applying for jobs or public benefits with false documents. It permits state judges to order deportations and creates a new offense, “lethal sale of fentanyl,” as part of a stated effort to address the drug crisis often linked politically to border security.

Advocacy groups warn the law could prompt racial profiling reminiscent of the SB 1070 era, when the “show me your papers” provision prompted boycotts and travel advisories that carried economic consequences for the state.

In court, Florence Project attorney Oscar Roman argued the measure undermines federal discretion over immigration enforcement. Representing Republican legislative leaders Warren Petersen and Steve Montenegro, attorney Brunn Roysdon countered that the law is intended to help federal authorities by steering people toward ports of entry under federal control and by imposing the same ultimate consequence, removal. He said the state would not interfere with ongoing federal proceedings, a point disputed by the nonprofit, which contends the state could arrest and deport individuals already permitted to remain under asylum law or who are in federal removal processes.

What comes next in the case

Although Liburdi refused to issue a temporary restraining order, the Florence Project’s motion for a preliminary injunction remains before the court. The parties are scheduled to return on Aug. 5 to discuss next steps in the litigation.

The case adds to a growing list of state-level measures testing the boundaries of criminal enforcement, drawing comparisons to disputes such as Tennessee’s homeless camping felony law that have also faced constitutional challenges.
