Highlights
- Prop. 314's Section 5, which criminalizes unauthorized border crossings outside ports of entry, became enforceable July 14, 2026.
- Attorney General Kris Mayes argues the Florence Immigrant and Refugee Rights Project cannot show any client has been arrested under the law.
- The Florence Project sought an immediate injunction, warning the law could trigger a wave of arrests and strain its legal-services capacity.
- Mayes warned the court that blocking the law would undermine the will of the 61% of Arizona voters who approved Prop. 314 in 2024.
Arizona Attorney General Kris Mayes told a federal court this week that a legal challenge to Proposition 314's most contested provision is premature because no one has been arrested under it, a posture that puts the Democrat in the unusual position of defending a law she publicly criticized while it was being crafted.
The Florence Immigrant and Refugee Rights Project, a nonprofit that provides free legal representation to non-citizens detained by ICE in Arizona, filed suit against the law earlier this month and asked the court to pause enforcement while litigation continues. Mayes and Republican legislative leaders, who are co-defending the law, opposed the request.
At issue is Section 5 of Prop. 314, which the source material describes as making it a state crime to cross Arizona's southern border outside an official port of entry. Voters approved the measure in 2024 with 61% support. The provision's effective date was tied to a similar Texas law; after a federal appeals court revived the Texas statute in May, Arizona's version came online July 14, according to reporting by the Tucson.com and 12News.
Assistant Attorney General Timothy Horley argued in a brief that the Florence Project's claims are speculative. "Because Section 5 has barely gone into effect, Florence Project has not shown and likely cannot show that anyone has been subject to arrest, detention, or prosecution for violating the illegal entry provision," Horley wrote.
The Florence Project countered that implementing the law could produce a wave of arrests statewide, forcing its attorneys to take on more cases or travel longer distances and potentially causing them to miss critical hearings. Mayes rebutted that arrests could just as likely be concentrated in the southern part of the state and that it remains unclear how much of their resources law enforcement agencies will devote to enforcement.
Mayes also pushed back on the Florence Project's argument that long-settled immigrants or even citizens could be swept up, noting that the law's delayed start date means its penalties apply only to people suspected of crossing on or after July 14.
On the public-interest question, Mayes' brief argued that an injunction would do more harm than good. "There is a strong public interest in preventing dangerous cross-border crimes, like human trafficking and drug smuggling," the brief states. "Restraining Section 5 will take away from law enforcement authorities a method that the Legislature and the voters of Arizona have decided would make the state safer."
The court has not yet ruled on the Florence Project's request for a preliminary injunction.
