Arizona Supreme Court · Case CV-25-0002-PR · 2026-03-10
Argument summary
AI-generated — not an official transcript or court record.
- Counsel for Mr. Mills argues that requiring him to obtain a professional engineering license is unreasonable because other engineers performing similar non-construction product design work are not required to be licensed.
- Mr. Mills' counsel contends that the Arizona Supreme Court's decision in *Arizona Downs* improperly abandoned the state's historical reasonableness test for economic liberty in favor of a deferential federal rational basis review that ignores factual evidence.
- The State argues that licensing is justified because engineering is a technical field where the general public lacks the skills to evaluate the quality and safety of the work, necessitating proof of qualifications for those offering services directly to the public.
- Justices questioned whether the distinction between full-time employees (who are exempt from licensing) and independent contractors (who must be licensed) is reasonable, noting that the work performed remains identical regardless of employment status.
- Counsel for Mr. Mills requested the Court to overrule *Arizona Downs* to the extent it applies federal *Williamson v. Lee Optical* standards, arguing that case involved unique gambling regulations and should not control common occupational licensing.
- The State maintained that while facts matter, a plaintiff must allege specific facts that overcome the presumption of legislative rationality, rather than simply arguing the law is unwise or imperfectly tailored.
