Background
Francisco Nunez Carrillo was convicted in June 2019 of two counts of aggravated assault and one count of discharging a firearm within city limits. The superior court sentenced him to concurrent terms of 24 years for the aggravated assault convictions and 3.75 years for the firearm offense. On direct appeal in 2020, one of Carrillo’s aggravated assault convictions was vacated as multiplicitous and violative of double jeopardy protections, while the remaining convictions were affirmed.
Carrillo subsequently filed two separate post-conviction relief petitions, which were dismissed. In December 2024, he petitioned the Arizona Supreme Court for habeas corpus relief based on unlawful imprisonment, asserting his two aggravated assault convictions were multiplicitous. When the supreme court denied that petition, Carrillo filed a habeas corpus petition in the superior court raising the same argument. The superior court denied the petition, and Carrillo appealed to the Court of Appeals.
The Court’s Holding
The Arizona Court of Appeals affirmed the denial of Carrillo’s habeas corpus petition. The court held that habeas corpus review is narrowly limited to jurisdictional issues and cannot be used to challenge the validity of convictions or sentences. The sole function of habeas corpus is to obtain release of one unlawfully detained based on jurisdictional defects, not to litigate the merits of conviction or sentencing validity.
The court noted that Carrillo’s petition, regardless of its title, essentially challenged the validity of his convictions, and therefore should have been treated as a post-conviction relief petition under Arizona Rule of Criminal Procedure 32. Even if recharacterized as such, the court found no colorable claim warranting relief because Carrillo had already participated in two Rule 32 proceedings and because this court had essentially granted his requested relief in the prior direct appeal when one aggravated assault conviction was vacated.
Key Takeaways
- Habeas corpus petitions are limited to jurisdictional defects and cannot be used to challenge conviction or sentence validity.
- Challenges to conviction or sentence validity must proceed through post-conviction relief mechanisms under Arizona Rule of Criminal Procedure 32, not habeas corpus.
- A petition challenging conviction validity will be deemed a post-conviction relief petition regardless of how it is titled, and is subject to Rule 32 limitations on successive filings.
- Carrillo’s prior successful appeal that vacated one conviction on double jeopardy grounds constituted the relief he was seeking in subsequent habeas petitions.
Why It Matters
This decision clarifies the procedural boundary between habeas corpus and post-conviction relief in Arizona. Practitioners must use the correct procedural vehicle to challenge convictions or sentences; using habeas corpus for such challenges is procedurally improper and will result in dismissal. The decision reinforces that habeas corpus is an extraordinary remedy limited to jurisdictional issues, not a vehicle for relitigating conviction validity.
The decision also illustrates Arizona’s treatment of successive post-conviction filings and the principle that courts will not entertain repeated petitions raising issues that have been previously adjudicated or essentially resolved on direct appeal. For defendants, this means exhausting post-conviction remedies during the direct appeal process is critical, as subsequent habeas petitions raising the same issues will be rejected.
