United States v. Brown
326 F. 3d 1143 (2003)
Rule of Law:
Psychological or psychiatric evidence is admissible to negate the specific intent (mens rea) element of a crime, but only if the defendant clearly demonstrates a direct link between the evidence and the required mental state, and the evidence does not merely assert an inability to conform conduct to the law or an impaired volitional control.
Facts:
- Edward J. Brown participated in a multi-state methamphetamine operation.
- A psychologist, Dr. Fred Lindberg, diagnosed Brown with post-traumatic stress disorder and chemical dependency.
- Dr. Lindberg testified that as a result of his condition, Brown did not have the capacity to conform his conduct to the requirements of the law.
- Dr. Lindberg also stated that at the time of his arrest, Brown did not have the capacity to 'make the correct choices.'
- Both Dr. Lindberg and the Bureau of Prisons psychologist, Dr. Ronald Riggs, concluded that Brown was not legally insane and was competent to stand trial.
Procedural Posture:
- Edward J. Brown was indicted in federal district court on drug and firearm charges.
- Brown initially pleaded not guilty and gave notice of his intent to rely on an insanity defense and to present expert testimony on his mental condition.
- At a competency hearing, the district court found Brown competent to stand trial.
- The government filed a motion in limine to exclude expert testimony concerning Brown's mental disease or defect.
- The district court granted the government's motion, finding the proffered testimony was impermissible evidence of volition and failed to establish a link to the mens rea for the charged offenses.
- Brown entered a conditional plea of guilty, reserving his right to appeal the district court's ruling on the motion in limine.
- After sentencing, Brown (appellant) appealed the district court's exclusionary order to the U.S. Court of Appeals for the Tenth Circuit, with the United States as the appellee.

Issue:
Did the district court abuse its discretion by excluding expert psychological testimony offered to negate a defendant's specific intent, when the testimony failed to establish a direct link to the required mental state (mens rea) and instead focused on the defendant's inability to control their conduct?
Opinions:
Majority - Murphy, Circuit Judge
No, the district court did not abuse its discretion by excluding the psychological testimony. The court held that while the Insanity Defense Reform Act (IDRA) does not bar all psychiatric evidence offered to negate the mens rea element of a specific intent crime, such evidence is only admissible if it is directly relevant to the defendant's mental state and not merely a theory of impaired volitional control. The court joined other circuits in distinguishing between permissible evidence that negates intent and impermissible evidence that functions as a justification or excuse, such as an inability to control one's actions. Here, Brown's proffered expert testimony from Dr. Lindberg focused on his inability to 'conform his conduct to the requirements of the law' and to make 'correct choices.' The court found this to be evidence of impaired volitional control, which was eliminated as a defense by IDRA. Brown failed to establish the required 'link or relationship between the specific psychiatric evidence offered and the mens rea at issue,' so the district court properly excluded it.
Analysis:
This decision aligns the Tenth Circuit with other federal circuits in interpreting the post-Insanity Defense Reform Act (IDRA) landscape for mental condition defenses. It affirms that while IDRA abolished the volitional prong of the insanity defense, it did not entirely foreclose the use of psychological evidence to challenge the prosecution's proof of specific intent. The case establishes a critical but narrow pathway for admitting such evidence, requiring defendants to show a direct, cognitive link between a mental condition and the absence of mens rea. This high bar prevents defendants from using psychiatric testimony as a backdoor to reintroduce an abolished 'inability to control oneself' defense, thereby preserving IDRA's core purpose while still allowing challenges to an essential element of the crime.
