The Illinois Appellate Court has upheld the conviction of Raul Calvillo for aggravated unlawful use of a weapon (AUUW). The court ruled that the statute under which he was convicted is constitutional, both on its face and as applied to him. This decision affects Calvillo, who was appealing his conviction, and it reinforces the legality of the AUUW statute in Illinois.

Calvillo's case began when he was charged with multiple counts of AUUW in 2001, at the age of 17. He was found guilty of possessing an uncased firearm in public and possessing a firearm before reaching the age of 21. After being sentenced to probation, his probation was revoked, and he served time in prison. In 2019, Calvillo sought to vacate his earlier convictions, arguing they were unconstitutional. The circuit court’s ruling on his petitions led to an appeal, which ultimately resulted in the current ruling from the Appellate Court.

The Appellate Court's ruling, filed on November 4, 2026, addressed Calvillo's claims that the AUUW statute violated his Second Amendment rights. The court concluded that the statute is constitutionally valid, stating, "Under the binding precedents of Mosley, Jordan G., and Aguilar, respondent's facial and as-applied challenges to subsection (a)(3)(I) of the AUUW statute *** all fail." This ruling affirms the earlier decisions that upheld age-based restrictions on firearm possession.

The court highlighted that legislative enactments have a strong presumption of constitutionality and that a defendant challenging a statute bears the burden of proving its invalidity. The court also noted that previous rulings had already addressed similar challenges to the AUUW statute, indicating a consistent legal interpretation regarding firearm regulations for minors.

Calvillo's arguments were based on the U.S. Supreme Court's decision in New York State Rifle & Pistol Ass'n, Inc. v. Bruen, which changed how courts analyze Second Amendment cases. However, the Appellate Court determined that prior Illinois Supreme Court decisions regarding age-based restrictions on firearm possession remain relevant and binding, even after Bruen.

The court's ruling has significant implications for similar cases in Illinois, reinforcing the constitutionality of the AUUW statute. It serves as a precedent for future challenges to firearm regulations, particularly those that involve age restrictions. The decision also underscores the importance of historical context in evaluating firearm regulations, as the court noted that there is a long-standing tradition of such restrictions.

Moving forward, this ruling may affect individuals facing similar charges under the AUUW statute. It clarifies the legal landscape regarding firearm possession for minors and reinforces the state's ability to regulate firearms in the interest of public safety.

As for what’s next, Calvillo may seek further legal recourse, but details were not available in the court filing regarding any potential appeals. The case highlights ongoing discussions about firearm regulations and constitutional rights in Illinois.
