Rule of Law:
The doctrine of diminished capacity is rejected; evidence of a mental abnormality short of legal insanity may not be used to negate the specific intent element of a crime. Furthermore, a statute requiring a defendant to prove the affirmative defense of insanity by a preponderance of the evidence does not violate the Due Process Clause.
Facts:
- Eddie Bethea and his wife, Barbara Bethea, were estranged and had a deteriorating marital relationship, marked by stormy and sometimes violent arguments over finances and suspicions of infidelity.
- On June 29, 1973, Bethea went to his wife's office.
- Following an argument at the office, Bethea shot his wife five times at close range, killing her.
- Bethea was apprehended shortly thereafter in an adjoining office without offering significant resistance.
- A defense psychiatrist testified that Bethea suffered from a 'hysterical neurosis of a dissociative type' brought on by severe emotional stress.
- Government psychiatric experts disagreed with the diagnosis, testifying that Bethea did not suffer from a mental disorder that would have significantly impaired his capacity for self-control.
Procedural Posture:
- Eddie Bethea was charged with first-degree murder in the Superior Court of the District of Columbia, the trial court.
- Pursuant to a pre-trial motion by the government, the court ordered Bethea to undergo a psychiatric examination.
- At trial, Bethea raised an insanity defense and requested jury instructions based on the ALI standard from 'United States v. Brawner' and the doctrine of diminished capacity.
- The trial court denied these requests and instructed the jury using the older 'Durham-McDonald' standard for insanity.
- The court also instructed the jury that, per D.C. Code § 24-301(j), Bethea had the burden of establishing his insanity defense by a preponderance of the evidence.
- The jury convicted Bethea of first-degree murder.
- Bethea appealed the conviction to the District of Columbia Court of Appeals, the highest court for D.C. local matters.

Issue:
Does evidence of a defendant's mental abnormality, short of legal insanity, require a jury instruction on the doctrine of diminished capacity to negate the specific intent element of first-degree murder?
Opinions:
Majority - Harris, Associate Judge
No. Evidence of a defendant's mental abnormality short of legal insanity is not admissible to negate the element of specific intent under a theory of diminished capacity. The court rejects this doctrine, maintaining a strict distinction between the legal concepts of mens rea and the affirmative defense of insanity. The court reasoned that the doctrine of diminished capacity contradicts the foundational legal presumption that all sane individuals possess a uniform capacity for criminal intent, and its adoption would improperly create a 'sliding scale' of criminal responsibility, a change best left to the legislature. The court also expressed concern that the doctrine would undermine the statutory scheme for mandatory commitment following an insanity acquittal, thereby jeopardizing public safety. While affirming the trial court's application of the existing 'Durham-McDonald' insanity test, the court prospectively adopts for future cases a modified version of the American Law Institute (ALI) standard. Finally, the court holds that the D.C. statute placing the burden on the defendant to prove insanity by a preponderance of the evidence is constitutional, as insanity is an affirmative defense, not an element of the crime that the prosecution must disprove.
Analysis:
This decision solidified the framework for criminal responsibility in the District of Columbia by emphatically rejecting the doctrine of diminished capacity. The court maintained a clear, binary distinction between legal sanity and insanity, preventing the introduction of a more subjective standard of culpability that it viewed as unworkable and dangerous. The prospective adoption of the modified ALI insanity test aligned D.C. with the modern trend in American jurisprudence, shifting focus from the vague 'product' test of Durham to a standard centered on the defendant's cognitive and volitional capacities. This case is significant for reinforcing the distinct legal roles of mens rea and the insanity defense and affirming the legislature's primacy in defining the scope of criminal responsibility.
