Standard of Proof
Commonwealth v. McHoul
Commonwealth Carries Full Burden
Prosecution must prove sanity beyond a reasonable doubt once defendant introduces credible evidence of lack of criminal responsibility.
Path A: Commonwealth Retrial under Mass. R. Crim. P. 36
Procedural Mechanics: Following a mistrial declared due to a genuine hung jury, the Commonwealth retains the statutory right to retry the defendant on all indicted charges (first-degree murder, strangulation, and assault and battery with a dangerous weapon).
Prosecution Strategy: Refine prosecution expert testimony regarding purposeful conduct, internet searches, and the temporal sequence of events to establish deliberate premeditation beyond a reasonable doubt, rebutting the defense's postpartum psychosis theory.
Defense Counter-Strategy: Call additional independent psychopharmacologists to demonstrate the severe overmedication cocktail (13+ psychiatric prescriptions) triggered acute involuntary akathisia and psychotic dissociation.
Key Precedent: Commonwealth v. Andrews, 427 Mass. 434 (1998)
Establishes that retrial after a genuine hung jury mistrial does not violate Massachusetts state or federal constitutional protections against double jeopardy where manifest necessity was established.
The McHoul Test: Lack of Criminal Responsibility (352 Mass. 548)
Under Massachusetts law, a person is not responsible for criminal conduct if at the time of such conduct as a result of mental disease or defect they lack substantial capacity either to appreciate the criminality (wrongfulness) of their conduct or to conform their conduct to the requirements of law.
Cognitive Prong (Appreciation of Wrongfulness)
Focuses on whether postpartum psychosis distorted the defendant's moral calculus such that she believed the acts were necessary, altruistic, or commanded by auditory hallucinations, destroying awareness of moral wrongfulness.
Volitional Prong (Conforming Conduct to Law)
Addresses irresistible impulse or overpowering command delusions: even if the actor intellectually recognized illegality, the mental disease destroyed the volitional power to inhibit or conform physical action.
Short deliberations weigh against manifest necessity; extended deadlock supports mistrial.
Retrial Permitted: Manifest Necessity Met
Under Commonwealth v. Cassidy and Mass. R. Crim. P. 25, the judge’s thorough polling, administration of the Tuey-Rodriguez instruction, and substantial jury deliberation establish unquestioned manifest necessity. Double jeopardy does not bar Commonwealth retrial.
Double Jeopardy Dismissal Probability
12%
Applicable Benchmark: Mass. Const. Pt. 1, Art. 26 & G.L. c. 263, § 7
Double jeopardy attaches only when a mistrial is declared without manifest necessity and without the defendant's consent.
