Rule of Law:
Evidence of a defendant's mental disease or defect is admissible to negate the mens rea element of a crime only in the rare case where it can be specifically and logically connected to the defendant's inability to form the requisite criminal intent. Such evidence is inadmissible if it merely suggests impaired judgment, poor choices, or a diminished capacity, as this would mislead the jury into considering defenses prohibited by the Insanity Defense Reform Act.
Facts:
- Between 1989 and December 2001, Edward M. Mezvinsky allegedly engaged in twenty-four separate fraudulent schemes.
- These schemes resulted in losses of over $10.4 million to various institutions and individuals.
- Mezvinsky suffers from a bipolar mental disorder, which he claims was undiagnosed and untreated for decades.
- During his travels to Africa in the 1990s, Mezvinsky ingested the anti-malaria drug Lariam (mefloquine).
- A Positron Emission Tomography (PET) scan of Mezvinsky's brain conducted on November 9, 2001, allegedly revealed frontal lobe organic brain damage.
Procedural Posture:
- On March 22, 2001, a Grand Jury returned a sixty-six count Indictment charging Edward M. Mezvinsky with fraud and related offenses in the U.S. District Court for the Eastern District of Pennsylvania.
- On July 2, 2001, Mezvinsky filed a notice of his intention to present an insanity defense pursuant to Fed. R. Crim. P. 12.2(a).
- On February 7, 2002, the Grand Jury returned a Superseding Indictment that added three additional counts.
- On February 25, 2002, Mezvinsky's counsel amended the notice, withdrawing the insanity defense and instead asserting a 'mental health defense' under Fed. R. Crim. P. 12.2(b) to negate the element of criminal intent (mens rea).
- The Government filed a motion to exclude Mezvinsky's proposed mental health defense.
- The District Court conducted a four-day evidentiary hearing to evaluate the scientific reliability and legal relevance of the proffered expert testimony before ruling on the government's motion.

Issue:
Does expert testimony regarding a defendant's bipolar disorder, frontal lobe brain damage, and Lariam-induced encephalopathy constitute admissible evidence to negate the mens rea element of fraud-related offenses when the testimony only suggests impaired judgment and does not establish an inability to form the specific intent to deceive at the time the offenses were committed?
Opinions:
Majority - Dalzell, District Judge
No. The proffered expert testimony regarding the defendant's mental conditions is not admissible because it fails to negate the specific mens rea required for the charged offenses and instead presents a prohibited diminished capacity defense. Under the standard established in United States v. Pohlot, evidence of a mental condition is admissible to negate mens rea only in the 'rare case' where it directly proves the defendant lacked the specific intent required for the crime. For the fraud charges against Mezvinsky, the essential mens rea is the 'capacity to deceive.' The court found that the expert testimony regarding Mezvinsky's bipolar disorder only established 'poor judgment' and 'bad choices,' and the experts conceded that individuals with bipolar disorder retain the capacity to deceive. Similarly, the evidence of brain damage from PET scans was deemed irrelevant, as the experts could not retrospectively determine Mezvinsky's mental state during the 12-year period of the alleged crimes or link the brain abnormalities to an inability to form deceptive intent. Finally, the claim that Lariam use caused toxic encephalopathy was speculative and not supported by scientific evidence showing a causal link to an incapacity to deceive. Applying Federal Rule of Evidence 403, the court concluded that the low probative value of this evidence was substantially outweighed by the danger of misleading the jury into considering a forbidden diminished capacity defense.
Analysis:
This decision exemplifies the district court's gatekeeping role under Daubert and strictly applies the Third Circuit's narrow interpretation of the mens rea defense in Pohlot. It reinforces that the Insanity Defense Reform Act of 1984 effectively foreclosed generalized diminished capacity defenses. The court's meticulous, point-by-point refutation of each proffered mental health claim establishes a high bar for defendants, requiring specific, scientifically grounded evidence that directly links a mental condition to the absence of the requisite intent at the time of the offense. This case serves as a clear warning that evidence suggesting 'bad judgment,' 'compulsion,' or a general lack of moral culpability is insufficient and will be excluded to prevent the jury from being confused or misled.
