Procedural Posture

Criminal / Appeal From Conviction and Sentence

  1. 1 Did the trial judge err by admitting the similar fact evidence?
  2. 2 Did the trial judge err in his instructions to the jury respecting the similar fact evidence?
  3. 3 Did the trial judge err by failing to give a limiting instruction respecting evidence of discreditable conduct apart from the similar fact evidence?

Ratio Decidendi

Similar fact evidence is admissible only where its probative value on a material issue (here consent or credibility) so outweighs its prejudicial effect that it does not lead to impermissible propensity reasoning; on these facts the prior witness's evidence was weak, potentially tainted by collusion, not sufficiently similar or distinctive, and highly prejudicial and therefore should have been excluded; failure to exclude required setting aside convictions and ordering a new trial.
