Procedural Posture

Criminal / Appeal (convictions and Sentence) From Judge Alone Trial in Superior Court

  1. 1 Whether an inconsistent criminal negligence causing death conviction should be set aside because of an acquittal for unlawful act manslaughter arising from the same facts
  2. 2 Whether fresh expert neuropsychological evidence should be admitted to order a new trial on capacity grounds
  3. 3 Whether the fresh evidence should be admitted for sentencing and whether sentence was demonstrably unfit

Ratio Decidendi

The criminal negligence causing death conviction is upheld because it is reasonable and supported by findings of fact while the acquittal for unlawful act manslaughter resulted from a legal error applying subjective foresight; fresh neuropsychological evidence is inadmissible on appeal to raise capacity-based reasonable doubt but is admissible for sentencing to reduce moral blameworthiness; consequently the original sentence is set aside and a global 14-year sentence substituted and credited for presentence custody to net 10 years and 2 months.

Court Disposition

Conviction appeal dismissed; sentence appeal allowed in part; fresh evidence admitted for sentencing but not for ordering a new trial; original sentences set aside and global sentence of 14 years substituted, with presentence credit applied to result in net 10 years 2 months custody.
