Why It Matters
The Arizona Court of Appeals has cleared a major constitutional hurdle for the state’s most aggressive immigration enforcement law, ensuring that local police and judges can continue exercising federal border authority. The ruling solidifies the legal framework for Proposition 314, which voters approved two years ago to criminalize unauthorized border crossings.
What Happened
As first reported by azmirror.com, a three-judge panel of the Arizona Court of Appeals issued a unanimous decision on Thursday upholding the Secure the Border Act. The court rejected a lawsuit filed in April 2025 by Living United for Change in Arizona (LUCHA), which argued that the ballot measure violated the state constitution by failing to designate a specific revenue source for the costs associated with housing and transporting undocumented immigrants.
Vice Chief Judge David Weinzweig wrote the opinion, stating that Proposition 314 designates state officials as a contingency plan rather than creating an outright mandate for state spending. The court reasoned that because local agencies are primarily responsible for enforcement, any financial burden would likely fall on local governments instead of the state’s general fund.
The lawsuit also challenged a provision allowing law enforcement to transport defendants to ports of entry or federal custody. LUCHA argued this infringed on judicial authority and invited racial profiling by relying on vague probable cause standards. The court dismissed these claims, ruling that the probable cause provisions simply reiterate existing due process mandates and require evidence thresholds to be met.
The decision marks the second significant legal defeat for opponents of the measure. Last month, the Arizona chapter of the American Civil Liberties Union dropped its own lawsuit against the law, citing a lack of evidence regarding arrests or mistreatment under the new statutes.
By the Numbers
63% — Percentage of Arizona voters who approved Proposition 314 two years ago.
Up to 6 months — Maximum jail time for unauthorized border crossing under the misdemeanor provision that took effect this summer.
April 2025 — Month when LUCHA filed its constitutional challenge against the Secure the Border Act.
Three-judge — Composition of the appellate panel that issued the unanimous ruling upholding the law.
Zoom Out
The court’s decision aligns with a broader national trend of state-level immigration enforcement initiatives gaining legal traction. A key factor in the ruling was the federal government’s waiver of fees for the Systematic Alien Verification for Entitlements (SAVE) program, which allows state and local agencies to verify immigration status for public benefit applicants. These fees were waived in April after President Donald Trump took office.
The appellate panel noted that even if verification fees are reinstated in the future, the resulting costs stem from federal policy decisions rather than a direct mandate of Proposition 314. This distinction helps insulate the state law from constitutional challenges related to unfunded mandates, a common legal battleground for state-level policy measures across the country.
What’s Next
LUCHA indicated it is considering asking the Arizona Supreme Court to review the appellate decision. If the high court declines to hear the case, the Secure the Border Act will remain fully enforceable without further judicial interference. Meanwhile, local law enforcement agencies continue to implement the misdemeanor provisions that have been active since this summer.
