State v. Caibaiosai

1985

Court: Wisconsin Supreme Court

Facts: Motorcycle accident while intoxicated kills passenger.

Posture: Convicted at trial, post-conviction motion denied, defendant appeals

Issue: Three issues:
  1. Is the homicide by OWI statute unconstitutional?
  2. Does the affirmative defense conflict with right against self-incrimination?
  3. Was failure to instruct on affirmative defense a violation of due process?

Holding:
  1. No.
  2. No.
  3. No.
  4. Affirmed.

Rule:
  1. There are only two elements: operating while intoxicated, and causing death. People make a conscious choice to do this, and we are OK punishing them for it.
  2. Self-incrimination is about compulsory testimony. The affirmative defense is voluntary.
  3. The state doesn't have to prove negligence: all the evidence here was speculative, so it was reasonable not to instruct.

Reasoning:

Dicta: Dissent (Abrahamson): the statute is unconstitutional, actually, because it allows punishment for events that happen by chance.
