The Arizona Court of Appeals recently ruled in the case of State v. Marquez, No. 1 CA-CR 26-0072, that Mariah Marquez did not receive adequate notice of a hearing that designated her offense as a felony. This decision is significant as it underscores the importance of proper notification in legal proceedings and its impact on defendants' rights.

Mariah Marquez was initially charged with nine felony drug offenses in January 2024. She pled guilty to one count of unlawful possession of drug paraphernalia, classified as an undesignated class-six offense. According to her plea agreement, Marquez was placed on probation for 18 months and required to complete substance abuse treatment. The agreement specified that her offense could not be designated a misdemeanor unless she successfully completed probation.

In December 2025, the Adult Probation Department recommended that the court designate Marquez’s conviction as a felony due to her failure to schedule an assessment for substance abuse treatment and her non-completion of the treatment program. The superior court discharged Marquez from probation and set a review hearing for the felony designation. However, the court sent the notice for this hearing to an address with an incorrect zip code, which Marquez claimed was not her current address.

Marquez did not attend the designation hearing, and her attorney objected to proceeding without her. The attorney explained that Marquez was experiencing homelessness and had not received notice of the hearing. Despite this, the superior court ruled that Marquez had sufficient notice because the court had mailed the notice to her last known address. The court then designated her offense as a felony, leading Marquez to appeal the decision.

The Court of Appeals, led by Judge D. Andrew Gaona, found that Marquez did not have actual notice of the designation hearing. The court emphasized that a defendant must be given actual notice and an opportunity to be heard regarding the designation of their offense. The ruling stated, "Because the record doesn’t show that Marquez had actual notice of—and was thus voluntarily absent from—the designation hearing, we vacate the felony designation and remand for further proceedings."

The court's decision highlighted that the superior court's finding of adequate notice was not supported by the record. It noted that while the court had sent the notice to Marquez’s last known address, there was no evidence showing that she had received actual notice of the hearing. The court referenced previous case law, stating that a defendant's absence from a hearing cannot be deemed voluntary without clear evidence of actual notice.

This ruling is significant because it reinforces the principle that defendants must be properly notified of hearings that affect their legal status. The court pointed out that a felony designation carries serious consequences for a defendant, and thus, they must be afforded the right to be present and heard during such proceedings.

The ruling vacates the felony designation for Marquez and sends the case back to the lower court for further proceedings. This means that the lower court will need to reassess the designation of Marquez's offense, ensuring that she is given proper notice and an opportunity to participate in any future hearings.

The decision may have broader implications for similar cases in Arizona, as it emphasizes the necessity of ensuring that defendants are adequately informed of legal proceedings that could impact their lives. It serves as a reminder for courts to verify that defendants receive proper notification, particularly in cases where individuals may have unstable living situations.

Moving forward, Marquez's case will be closely monitored to see how the lower court addresses the issue of her felony designation. The court's ruling does not prevent the state from pursuing a felony designation in the future, provided that Marquez is given proper notice and the opportunity to be heard. The outcome of this case could influence how similar cases are handled in the future, particularly in relation to defendants' rights and due process.

As of now, it remains unclear if the state will seek to appeal this ruling or if there are any related cases pending that could further shape the legal landscape surrounding felony designations in Arizona. The court filing did not provide details on any potential appeals or related cases.
