State v. Mitchell D. Green
992 N.W.2d 56
Wis.2023Background
- Mitchell Green was charged with child trafficking. The victim (S.A.B.) testified that Green drove her to a hotel where she was forced to perform a sex act.
- Green called his cousin, Jonathan Cousin, who testified he — not Green — drove S.A.B. to the hotel and described facts that could point to a third-party perpetrator.
- The State argued Cousin's testimony was unanticipated "Denny" (third‑party perpetrator) evidence and that the defense failed to provide advance notice or seek a pretrial admissibility ruling; the court agreed and, after a lunch recess, declared a mistrial as the testimony could not be "unrung."
- Green moved to dismiss on double jeopardy grounds; the circuit court denied the motion, the court of appeals reversed, and the State appealed to the Wisconsin Supreme Court.
- The Wisconsin Supreme Court reversed the court of appeals, holding the trial judge exercised sound discretion and that manifest necessity justified the mistrial, so retrial does not violate double jeopardy.
Issues
| Issue | Plaintiff's Argument (State) | Defendant's Argument (Green) | Held |
|---|---|---|---|
| Whether retrial is barred by double jeopardy because the mistrial lacked "manifest necessity" | Trial judge properly exercised sound discretion; unexpected introduction of unvetted Denny evidence and its timing made a curative remedy inadequate, so mistrial was manifestly necessary | Mistrial was unnecessary because testimony was (and ultimately was) admissible; retrial therefore violates double jeopardy | Retrial permitted — court held the trial court acted with "sound discretion" and manifest necessity justified mistrial |
| Whether the trial court reasonably treated the State's pretrial motion in limine as effective despite no on‑record ruling | Reasonable for the trial judge (who was newly assigned) to presume pretrial orders limited surprise Denny evidence, especially when defense did not deny that understanding | Trial court erred by presuming the motion had been granted when record contains no ruling; that presumption is unwarranted | Court found the presumption not irrational under the circumstances and therefore not erroneous for purposes of the manifest necessity analysis |
| Whether Denny third‑party perpetrator evidence requires advance notice and pretrial vetting | Denny evidence implicates State and court interests; advance notice and pretrial adjudication are necessary when defense seeks to present a known third‑party perpetrator at trial | Denny does not mandate notice in all circumstances; here Cousin was disclosed on the witness list and the State could have sought discovery | Court agreed that Denny evidence typically should be vetted pretrial and that the defense’s failure to correct the court’s understanding supported the trial judge’s concern |
| Whether the trial court should have considered admissibility (or other alternatives) before declaring a mistrial | Trial court heard both sides, considered curative instructions and sanctions, weighed timing/impact on jury, and rationally concluded alternatives could not "unring the bell" | Court could and should have made a preliminary admissibility determination before halting the trial — evidence was later deemed admissible, so mistrial was unnecessary | Court held the judge adequately considered alternatives and explained why they were insufficient; therefore the exercise of discretion was sound |
