Rule of Law:
The diminished capacity defense is available in West Virginia to permit a defendant to introduce expert testimony regarding a mental disease or defect that rendered the defendant incapable, at the time the crime was committed, of forming a mental state that is an element of the crime charged.
Facts:
- In 1989, Robert Joseph was in a motorcycle accident that caused a severe crush injury to his left frontal skull.
- On the night of March 28, 2001, Joseph was drinking at his home with Jessica Martin and Duane Lucas.
- After Ms. Martin rejected his advances and flirted with Mr. Lucas, Mr. Joseph became angry, ordered them to leave, and fired two shots from his porch as they departed.
- Concerned about Ms. Martin, Joseph searched for her and eventually confronted Scott Light, who had given Martin and Lucas a ride.
- An argument erupted in Mr. Light's driveway, during which Mr. Light opened Joseph's truck door and, according to Joseph, slapped him on the head.
- Joseph testified that upon being slapped, he saw a "blue flash," grabbed a pistol from the truck seat, and fired five shots, mortally wounding Mr. Light.
- Joseph then backed his vehicle over Mr. Light while leaving the scene.
- Shortly after, Joseph called 911 from his parents' home, reported that he had shot Mr. Light, and waited for the police to arrive.
Procedural Posture:
- The State charged Robert Joseph with first-degree murder in a West Virginia circuit court (trial court).
- At trial, Joseph sought to introduce expert testimony to support a diminished capacity defense based on a prior brain injury.
- The circuit court heard the expert testimony 'in camera' and ruled it was insufficient to support the defense, thereby excluding it from the jury's consideration.
- The jury convicted Joseph of first-degree murder with a recommendation of mercy.
- Joseph filed a motion to set aside the verdict, which was denied by the circuit court.
- The circuit court sentenced Joseph to life in prison.
- Joseph (appellant) appealed his conviction and sentence to the Supreme Court of Appeals of West Virginia.

Issue:
Does a trial court err by excluding expert testimony offered to establish a diminished capacity defense, where the expert opines that a defendant's mental defect rendered them incapable of forming the requisite specific intent for murder under the circumstances of the crime?
Opinions:
Majority - Davis, Justice
Yes, a trial court errs by excluding expert testimony offered to prove a defendant's diminished capacity at the time of the criminal act. The diminished capacity defense allows a defendant to introduce expert testimony about a mental disease or defect to show they were incapable of forming the specific intent required for the charged crime. The trial court misapplied this doctrine by requiring the expert to testify that the defendant was generally incapable of forming intent, rather than focusing on whether the defendant's mental defect rendered him incapable of forming intent at the time of the crime and under the specific circumstances. Dr. Solomon's testimony, which stated that Joseph's brain injury diminished his capacity to form premeditation, malice, and intent under the specific, rapid circumstances of the confrontation, was sufficient to present the defense to the jury. Therefore, the exclusion of this testimony was a reversible error.
Analysis:
This landmark West Virginia case formally adopts the diminished capacity defense, aligning the state with numerous other jurisdictions and the Model Penal Code. The decision clarifies that diminished capacity is not an affirmative defense that excuses a crime (like insanity), but rather a rule of evidence that allows a defendant to negate the specific intent element (mens rea) of a crime. This holding allows defendants with relevant mental health evidence to challenge the prosecution's case-in-chief, potentially leading to a conviction for a lesser-included offense that does not require specific intent, rather than the primary charge. The case underscores the due process principle that a defendant must be allowed to present a complete defense, including evidence that contests a fundamental element of the charged offense.
