Gilbert Dudley, III v. State of Florida, 139 So. 3d 273

Defendant Gilbert Dudley was convicted by a jury of two counts of sexual battery under § 794.011(4)(e), for sexual acts with a victim statutorily defined as “mentally defective.”
The victim was an adult with significant cognitive impairments (IQ scores in the 50–61 range), diagnosed mental disorders, limited independent functioning, and a psychologist testified she was permanently incapable of appraising the nature of her conduct.
The trial court set aside the verdicts and dismissed charges, concluding the State failed to prove the victim was “mentally defective” as a matter of law, relying on earlier precedent.
The Fifth District Court of Appeal, en banc, reversed, holding the evidence was sufficient and certifying conflict with the First District’s decision in Mathis on the statutory meaning of “mentally defective.”
The Florida Supreme Court accepted jurisdiction to resolve the conflict and review whether the term “mentally defective” (defined in § 794.011(1)(b) as a mental disease or defect rendering a person incapable of appraising the nature of his or her conduct) should be equated with legal insanity or competence to testify.

Issue	Plaintiff's Argument	Defendant's Argument	Held
Whether “mentally defective” is equivalent to competence to testify	State: statutory phrase refers to inability to appraise conduct; competence to testify is a different inquiry and does not preclude finding mental defectiveness	Dudley: argued that victim was competent to testify and precedent (Mathis) precludes mental defectiveness finding when witness is competent	Court held competence to testify is a distinct concept and does not preclude a jury finding of “mentally defective” under § 794.011(1)(b)
Whether “mentally defective” requires total or complete lack of mental capacity or equates to legal insanity	State: the statute requires incapacity to appraise the nature of conduct — diminished judgment, not total lack of capacity	Dudley/Mathis: argued Mathis and related precedent treated the term as akin to insanity or requiring near-total incapacity	Court held the statutory term does not require total lack of mental capacity nor equate to legal insanity; it denotes significantly diminished ability to appraise the nature of one’s conduct
