PHOENIX, Arizona — Arizona has asked a federal judge to throw out the Trump administration's lawsuit against Proposition 308, the voter-approved law that lets graduates of Arizona high schools pay in-state tuition at the state's public universities and community colleges regardless of immigration status. State attorneys urged US District Judge Murray Snow to dismiss the Justice Department's case, arguing the federal government cannot show a concrete and imminent injury of its own — any economic effect of the lower tuition rate falls on Arizona and its institutions, not on the United States. State attorney Hayleigh Crawford made the standing argument for Arizona, according to reporting by the Arizona Capitol Times summarised by WiseVoter on Monday, November 2. Judge Snow has not said when he will rule.

What is actually at stake is a price gap measured in tens of thousands of dollars a year. At the University of Arizona, in-state undergraduate tuition is $13,906 a year against $43,068 for out-of-state students — a difference of roughly $29,000 (yaani about $40,000 Canadian) every single year of a degree. Proposition 308, which took effect on December 5, 2022, decides which side of that gap a young person who grew up and went to school in Arizona lands on, whatever their immigration paperwork says.

What Proposition 308 actually says

Under Proposition 308, a student qualifies for in-state tuition at an Arizona public university or community college if they attended a high school or homeschool while physically present in Arizona for at least two years, and graduated from an Arizona high school or homeschool, or earned a high-school equivalency diploma in Arizona. Eligibility does not depend on lawful immigration status or on state residence as such — it is keyed to schooling in Arizona. The measure, a legislative referral passed by voters in November 2022 with 51.2 percent support, also repealed the older law (A.R.S. § 15-1825) that had made students without lawful status ineligible for state-funded financial aid. The Arizona Board of Regents, which governs the state's public universities, states plainly in its guidance that Proposition 308 remains in effect today: the filing of the lawsuit changed nothing, and eligible students should keep applying for admission, in-state tuition and state financial aid as usual.

The federal government's case

The Justice Department sued Arizona on August 27, 2026, in a batch of four lawsuits that also targeted New Mexico, Oregon and Washington, bringing its campaign against state in-state-tuition laws to 21 states. The federal theory rests on a 1998 statute (8 U.S.C. § 1623) that bars states from giving residency-based higher-education benefits to immigrants not lawfully present unless every US citizen receives the same benefit regardless of where they live. Associate Attorney General Stanley E. Woodward Jr. said the four states “are pushing citizens to the side and ignoring federal law,” according to the Justice Department's release. The department's Arizona complaint says at least 720 undocumented students received in-state rates in fall 2025, including 432 at Arizona State University, and estimates ASU alone gave up about $10.5 million in tuition as a result; ASU's published gap is $14,814 a year for residents against $39,262 for nonresidents. Those are the department's figures, presented as its case — they have not been independently verified, and Arizona disputes the legal conclusion drawn from them.

Arizona's answer: schooling, not residence — and no injury to Washington

Arizona's defence has two layers. The first is about standing, the argument pressed on Judge Snow: the United States itself has not lost tuition money, because the universities that charge less are Arizona institutions; any alleged harm accrues to the state, so the federal government is the wrong plaintiff. The second is about the statute's wording, as the Arizona Attorney General's office frames it: Proposition 308 “doesn't condition eligibility on residence” but on high-school attendance — and § 1623, the state argues, is written in the language of residency benefits. That attendance-versus-residence distinction is the hinge the whole case turns on, and it is the same structure used by roughly two dozen states whose laws the Justice Department is now challenging one by one.

A long argument: from Proposition 300 to Proposition 308

Arizona has fought over this classroom door before. In 2018, the Arizona Supreme Court ruled that Proposition 300 — an earlier voter measure — barred subsidised tuition for students not legally in the country, ending a period in which DACA recipients had been offered in-state rates following a 2015 superior-court ruling; the Board of Regents discontinued those rates in April 2018 and complied with the ruling. Four years later the voters themselves reversed the position: Proposition 308 passed in November 2022 and took effect that December, restoring in-state eligibility on the schooling-based test described above. The Trump administration's 2026 lawsuit, filed after an executive order directing the Justice Department to act against states giving benefits to non-citizens that are not given to all citizens, is the third act of that argument — this time with the federal government, not the state courts, holding the pen.

The wider map: 21 states, and the first real test

Arizona is not being sued in isolation. According to The College Investor's tracking of the Justice Department campaign, courts have already blocked similar laws in Texas, Kentucky and Oklahoma by permanent injunction and in Nebraska by consent decree, while cases remain pending in a long list of states including California, New Jersey, New York, Colorado, Minnesota, Virginia, Maryland, Kansas, Massachusetts, Rhode Island, Connecticut and Vermont. Several of the department's early wins came quickly and without a full fight. Arizona is different in two ways its defenders emphasise: the law was enacted by the voters themselves, not just a legislature, and the state is actively contesting the federal reading of the statute. That makes Judge Snow's courtroom one of the first real tests of whether the “high-school attendance, not residency” structure survives § 1623.

What it means for students right now

For a student — or a family in Phoenix, Tucson, Mesa or Yuma doing the arithmetic on a degree — Monday's hearing changed nothing on the ground, and the Board of Regents says so explicitly: Proposition 308 remains in effect, no immediate action is required, and any change to eligibility would require a further court order. The board's advice is to continue education plans as normal. The honest caveat travels with it: the litigation is real, it is in its early stages, and the board itself expects it to take months or longer — so a student starting a four-year degree on an in-state rate under Prop 308 is doing so while a federal judge holds a motion that could, eventually, change the rule mid-degree.

What happens next

Judge Snow will rule on Arizona's motion to dismiss on his own timetable; no date has been announced, and the court has not granted the Justice Department's underlying request to declare the Arizona law inconsistent with federal law and bar its enforcement. Watch two things: whether the department seeks a preliminary injunction before the spring 2027 term — which would put current students' rates in play immediately rather than at the end of the case — and how Snow treats the standing argument, because a dismissal on standing would end this lawsuit without settling the underlying § 1623 question for the other twenty states. Until a court orders otherwise, Prop 308 rates stand.
