OTHER INFORMATION

In Keating v. State (2026), Vice Chief Justice John Lopez joined the majority of the Arizona Supreme Court in deciding whether Proposition 144 violated Arizona’s Separate Amendment Rule. Prop. 144 contains six election-related provisions, including citizen-only voting and registration, restrictions on foreign campaign spending, voter ID, election tabulation, and limits on election laws. The court held that the provisions were sufficiently related because they all concern election administration and share the goal of protecting elections from ineligible participation and foreign influence. 

In Arizona for Abortion Access v. Toma (2024), Vice Chief Justice Lopez authored the Arizona Supreme Court’s decision order holding that the Legislative Council’s use of the phrase “unborn human being,” taken from existing Arizona law, did not violate the requirement for an impartial voter-pamphlet analysis. The Court reversed the lower court and allowed the voter pamphlet to proceed.

In the Court’s later full opinion, Arizona for Abortion Access v. Montenegro (2025),, Lopez joined the majority, which explained that using the statutory language accurately described existing law. The Court emphasized that the case concerned the impartiality of the voter guide, not the legality of abortion itself.

In Planned Parenthood Arizona v. Mayes/Hazelrigg (2024), in which Justice Lopez authored the Arizona Supreme Court’s majority opinion, the Court considered whether newer abortion laws had replaced or limited Arizona’s 1864-era abortion ban. The Court held that they had not, meaning the older ban could be enforced. The Court relied on the statutory language and legislative history, concluding that the newer law did not independently authorize abortions after the U.S. Supreme Court’s decision in Dobbs ended the federal constitutional right to abortion. The Court did not decide whether the ban itself was constitutional, leaving those questions for the lower court.

In Arizonans for Second Chances, Rehabilitation, and Public Safety v. Hobbs (2020), in which Justice Lopez joined the majority and wrote a concurrence, the Arizona Supreme Court considered whether initiative groups could bypass Arizona’s constitutional requirement for in-person, witnessed signatures during the COVID-19 pandemic. The Court held that the Secretary of State could not accept electronic signatures because doing so would effectively require the judiciary to rewrite the Constitution and election laws. Lopez emphasized that allowing the Court to suspend constitutional rules during an emergency would weaken the rule of law and improperly expand judicial power. He concluded that the pandemic’s temporary burden on ballot access was preferable to permanently changing the law by judicial fiat.

In Brush & Nib Studio, LC v. City of Phoenix (2019), in which Justice Lopez joined the majority, the Arizona Supreme Court considered whether Phoenix could require a Christian-owned art studio to create custom wedding invitations for same-sex weddings under the city’s anti-discrimination law. The Court held that the city could not force the artists to create those invitations because doing so would require them to express a message that conflicted with their religious beliefs. The Court relied on Arizona’s free-speech and religious-freedom protections and found that the invitations were protected expression, not simply a service. Lopez’s vote therefore supported protecting religiously objecting businesses from being required to create expressive products for same-sex weddings.

In State v. Nunez-Diaz (2019), in which Justice Lopez concurred in the result, the Arizona Supreme Court considered whether a defendant who was already subject to deportation could show prejudice from his lawyer’s failure to explain that a guilty plea would cause severe immigration consequences. Lopez agreed that Nunez-Diaz was entitled to relief, but for a narrower reason than the majority. He concluded that deportation and loss of possible immigration relief were too speculative to count as prejudice because Nunez-Diaz was already deportable. However, the plea created a permanent bar to returning to the United States, which was a direct and certain harm. Lopez therefore found that this specific harm justified relief.
