Appeals court rejects challenge to Arizona's new border policing law

For Tucson residents and local law enforcement agencies, Arizona’s new border policing law remains in place after a state appeals court rejected a legal challenge brought by Living United for Change in Arizona. Proposition 314 allows police to arrest people who cross into Arizona from Mexico somewhere other than a port of entry and charge them with a state misdemeanor. The ruling keeps that authority available across the state, including communities in Southern Arizona that are closest to the international border and most likely to feel its effects.

The unanimous decision, issued Thursday by a three judge panel of the Arizona Court of Appeals, upheld Proposition 314, which voters approved in 2024 by 62.5 percent to 37.5 percent. The measure was designed to address people who enter the country outside official ports of entry, an area traditionally handled under federal immigration law. The court’s opinion was written by Judge David Weinzweig, who said the challenge could not proceed because LUCHA did not have legal standing to bring it.

LUCHA filed its lawsuit in 2025, arguing that several parts of Proposition 314 conflict with constitutional protections. The organization said the law could be enforced in a discriminatory way, particularly against people who share the race, ethnicity or national origin of migrants arriving from the southern border. It also challenged the measure’s arrest standards, its funding provisions and the decision to make some enforcement provisions dependent on the outcome of litigation involving a similar Texas law.

The law is structured to encourage people arrested under it to agree to leave the United States rather than serve time in an Arizona jail. If they agree to deportation, the charges against them would be dismissed. LUCHA argued that this arrangement could be misapplied against its members and others who are especially vulnerable to being treated as suspected border crossers. Weinzweig said the possibility of future misapplication was not enough to support a lawsuit seeking a court declaration. Such relief, he wrote, must be based on facts that already exist, not on events that might occur later.

The appeals court’s reasoning follows a separate decision issued in July by U.S. District Court Judge Michael Liburdi. He dismissed a challenge from the Florence Immigrant Rights and Refugee Project after finding that the group had not shown anyone had actually been affected by Proposition 314. In the state case, the judges likewise concluded that LUCHA had not demonstrated a present injury. That leaves the law standing while potentially affected people and organizations could face future legal questions if enforcement begins or produces specific consequences.

The court also rejected LUCHA’s argument that Proposition 314 does not provide constitutionally adequate standards for arrests. The measure identifies an officer’s own observation, a recording or any other constitutionally sufficient indication of probable cause as possible bases for an arrest. Although the phrase involving probable cause is not specifically defined in the law, Weinzweig said it refers to the same constitutional standards already required under the Fourth Amendment, which protects against unreasonable searches and seizures.

Funding was another central issue. Arizona’s Constitution requires ballot measures that mandate state spending to identify a new source of revenue to cover those costs. LUCHA argued that Proposition 314 violates that rule because it directs the Department of Corrections to transport people who agree to leave the country to the border, creating a spending obligation without new funding. The court interpreted the law differently. Weinzweig said the required transportation duty primarily falls on local law enforcement agencies, and that state expenses arise only if a local agency cannot hold someone while the deportation arrangement is completed. Because that situation is only a possibility, he characterized the state cost as a contingency rather than a mandate.

The court also found no illegal transfer of legislative authority in Proposition 314’s connection to Texas Senate Bill 4. Arizona lawmakers modeled the border crossing and deportation provisions on the Texas measure and wrote the law so those provisions could not take effect until a final federal court ruling on Texas’ law. Challengers argued Arizona lawmakers had improperly tied the state’s policy to events outside Arizona. Weinzweig rejected that position, saying the Legislature had not surrendered its lawmaking power simply because the Arizona provisions depend on the legal status of the Texas statute. A federal appeals court has upheld the Texas law, although questions remain about whether and how it can be enforced.

Alejandra Gomez, LUCHA’s executive director, sharply criticized the ruling and said the organization has not decided whether to ask the Arizona Supreme Court to review it. She said the decision comes as the Trump administration expands federal immigration enforcement into more areas of daily life. Gomez warned that Proposition 314 could give Arizona another way to target immigrant communities, pull state and local institutions further into immigration enforcement and require taxpayers to support a law whose costs remain uncertain. For Tucson and other Southern Arizona communities, the next major question is whether the law will be enforced in specific cases, and whether those cases produce new constitutional challenges that courts can consider on their merits.
