Ariz. R. Crim. P. 26.13
As amended through December 6, 2023
If the court imposes separate sentences of imprisonment on a defendant for two or more offenses, the sentences run consecutively unless the judge expressly directs otherwise. This rule applies even if the offenses are not charged in the same indictment or information. There is no presumption favoring consecutive sentences rather than concurrent sentences.
