Arizona DUI & Criminal Defense Attorney Blog
Arizona’s rape shield law blocks most evidence of a victim’s sexual history from being used at trial. But the law contains exceptions—including one for evidence showing the “source or origin” of “trauma.” In State v. Hernandez, decided March 5, 2026, the Arizona Court of Appeals (Division One) ruled that this trauma exception covers only physical injury—not emotional or psychological harm. This published opinion narrows the defense tools available in sex crime cases across Maricopa County and the rest of the state. If you are facing sex crime charges in the Phoenix area, James Novak is a former prosecutor who understands how evidentiary rulings like this one shape the defense.
What Did the Court Decide?
The Court of Appeals accepted a special action brought by the Maricopa County Attorney’s Office and reversed a Superior Court ruling. The case involved Jose Hernandez, who was charged with child molestation. The alleged victim—a child—reported being molested not only by Hernandez, but also by two other family members on separate occasions.
Hernandez wanted to introduce evidence of the other molestations at trial. His argument: the child’s emotional trauma from those other incidents caused her to confuse who abused her, and that confusion meant she may have incorrectly identified Hernandez as the perpetrator. He claimed this evidence fit under A.R.S. § 13-1421(A)(2)—the provision of Arizona’s rape shield law that allows evidence of a victim’s sexual history when it shows the “source or origin of . . . trauma.”
The Superior Court agreed with Hernandez and allowed the evidence in. The state then filed a special action, and the Court of Appeals reversed. The appellate court held that the word “trauma” in Section 13-1421(A)(2) means only physical injury—not emotional or psychological harm.
Why Does This Matter for Your Defense?
This ruling matters because it limits what a defense attorney can argue when trying to introduce a victim’s sexual history at trial. Here is how the court reached its decision and why it could affect your case.
The court read “trauma” in context, not in isolation. The exception in Section 13-1421(A)(2) lists four things that may allow inquiry into a victim’s sexual history: semen, pregnancy, disease, and trauma. The first three—semen, pregnancy, and disease—are all physical or biological evidence. Using a legal rule called noscitur a sociis (“a word is known by the company it keeps”), the court concluded that “trauma” must also mean something physical. Emotional trauma does not fit with the other items on that list.
Emotional trauma cannot be traced to one cause. The court pointed out a key practical difference: physical trauma, like bruising or injury, can be linked to a specific event. Emotional trauma cannot. Many events and circumstances contribute to psychological harm, and the existence of one traumatic experience does not make another more or less likely. Evidence of emotional trauma from other incidents would not actually “refute” the charges against the defendant.
The ruling protects victims but narrows defense options. Arizona’s rape shield law was designed to prevent “character assassination” of victims at trial. The court concluded that interpreting “trauma” broadly to include emotional harm would undermine those protections, because virtually all victims of sexual abuse suffer emotional distress. Allowing that as a gateway to their sexual history would swallow the rule.
Sex crime cases often turn on how evidence rules are applied. An experienced defense attorney must know which arguments courts will accept and which they will reject after rulings like this one. James Novak’s background as a former Maricopa County prosecutor—combined with his M.A. in Psychology and Counseling—gives him a unique advantage in evaluating how these evidentiary issues affect a defense strategy.

How Does This Affect Sex Crime Cases in Arizona?
Under A.R.S. § 13-1421, Arizona’s rape shield law still provides several exceptions that allow a defendant to introduce evidence of a victim’s prior sexual conduct. Those exceptions include evidence of past sexual conduct with the defendant (if consent is at issue), evidence showing the source of physical evidence like semen or pregnancy, evidence supporting a motive to falsely accuse, and evidence of prior false allegations of sexual misconduct.
What this ruling eliminates is the argument that emotional or psychological trauma alone can open the door to a victim’s sexual history. A defendant must now show a connection to physical evidence—such as injury, pregnancy, or disease—to invoke the Section 13-1421(A)(2) exception.
The court did leave one door open. Hernandez argued in the alternative that his constitutional right to present a complete defense required the evidence to be admitted regardless of the rape shield law. The Court of Appeals declined to address that argument, noting the trial court had not considered it. This means constitutional due process arguments could still provide a path in future cases—but that question remains unresolved.
Frequently Asked Questions
What is Arizona’s rape shield law?
A.R.S. § 13-1421 generally prohibits the admission of evidence about a victim’s sexual history in prosecutions for sex offenses. The law contains limited exceptions, such as evidence of prior sexual conduct with the defendant or evidence showing the source of physical evidence like semen, pregnancy, disease, or physical trauma.
Can a defendant still challenge a victim’s identification in a sex crime case?
Yes. A misidentification defense is still available, but after this ruling, the defense cannot use the trauma exception in Section 13-1421(A)(2) to introduce a victim’s sexual history based solely on emotional trauma or confusion. Other exceptions or constitutional arguments may still apply depending on the facts.
Is this ruling binding on all Arizona courts?
Yes. This is a published opinion from the Arizona Court of Appeals, Division One. Published opinions create binding precedent in Arizona, unlike unpublished memorandum decisions.
