Background

Carlos Mojica was convicted of first-degree felony murder and child abuse. He does not appeal his murder conviction but challenges only his child abuse conviction and sentence. Mojica brought a three-year-old child (C.T.) along during a planned robbery with the child’s mother. During the robbery, Mojica attacked a victim who screamed; the child cried hysterically. Mojica fled the scene in a pickup truck driven by the child’s mother, and the victim was run over and killed by the vehicle. Mojica was convicted under Florida Statute § 827.03(1)(b)2, which criminalizes an intentional act that could reasonably be expected to result in mental injury to a child.

The state prosecuted Mojica under a theory that his intentional acts at the crime scene could reasonably be expected to cause mental injury to the child, but presented no expert testimony regarding the child’s actual or potential mental injury. The trial court denied Mojica’s motion for acquittal and instructed the jury that mental injury must be “supported by expert testimony,” per Florida’s standard jury instruction and statute.

The Court’s Holding

The majority held that Florida Statute § 827.03(1)(d), which defines “mental injury” as requiring proof “supported by expert testimony,” applies to all child abuse prosecutions involving mental injury—whether the mental injury actually resulted or could reasonably be expected to result. Because the statute explicitly defines the term “mental injury” and requires expert testimony, courts must apply that definition consistently throughout the statute. The legislature cannot be understood to have used the same term with different meanings in different subsections of the same statute.

The majority rejected the state’s argument that the expert testimony requirement applies only when actual mental injury is proven, not when mental injury could reasonably be expected to result. The court noted that to accept this interpretation would require rewriting the statutory definition and using “mental injury” to mean two different things in the same sentence. Since the state failed to present expert testimony supporting any mental injury—actual or expected—Mojica’s conviction could not stand, and it was reversed.

The court emphasized that although the facts were disturbing, the narrow legal question was one of statutory interpretation governed by the “supremacy-of-text” principle, which holds that “the words of a governing text are of paramount concern.” The legislature has sole authority to criminalize conduct; courts may only apply statutes as written, not improve them.

Key Takeaways

  • Florida statute § 827.03(1)(d) requires expert testimony to prove “mental injury” in all criminal child abuse prosecutions, regardless of whether the charge involves actual infliction of mental injury or mental injury that could reasonably be expected to result.
  • When the legislature defines a statutory term, courts cannot redefine it or apply different meanings in different parts of the statute, even if doing so would simplify prosecution.
  • The elevated expert testimony requirements for mental injury in criminal child abuse cases (applied only to criminal prosecutions, not family or dependency court) must be honored uniformly across all relevant subsections.
  • A conviction cannot be upheld when a statutorily required element of proof—here, expert testimony regarding mental injury—is absent, regardless of how compelling the underlying facts may be.

Why It Matters

This decision significantly restricts how Florida prosecutors can pursue child abuse charges involving mental injury. By requiring expert testimony for all mental injury theories—including cases where the injury is only expected, not proven to have occurred—the ruling substantially raises the evidentiary burden on the state. Prosecutors can no longer rely solely on the facts and circumstances of a crime (such as a child witnessing violence or being present during a dangerous felony) to establish mental injury; they must now obtain qualifying expert testimony in every case involving mental injury allegations.

The decision reflects a fundamental principle of statutory interpretation: courts must respect legislative definitions and cannot rewrite statutes to make prosecution easier or to override what they perceive as the legislature’s unwise policy choices. If the state believes the expert testimony requirement creates obstacles to prosecuting child abuse, the remedy lies with the Florida legislature, not the courts. The dissent argued this interpretation renders the “reasonably expected to result” theory duplicative of the “actual infliction” theory, suggesting legislative reconsideration may follow.
