Michigan v. Bynum (Opinion - Leave Granted)
Annotate this Case
Levon Bynum was charged with first-degree murder, two counts of assault with intent to murder, carrying a concealed weapon, and felony-firearm following a shooting that had occurred outside a party store in Battle Creek. Bynum and some of the others present were alleged to be members of the Boardman Boys gang, whose territory bordered the party store. Bynum claimed that he acted in self-defense. An officer in the Battle Creek Police Department's Gang Suppression Unit, was proffered at trial as an expert witness on gangs, gang membership, and gang culture with a particular expertise about Battle Creek gangs. The court allowed the officer's testimony and his PowerPoint presentation, concluding that the evidence was relevant to prove Bynum's motive for shooting the victims. Defense counsel did not specifically object to any of this testimony after the initial, general objection to the testimony, and the jury found Bynum guilty as charged. Bynum's appellate defense counsel subsequently moved for a new trial, arguing the ineffective assistance of trial counsel for failing to object to the officer's testimony as improper propensity evidence. The court rejected the ineffective-assistance claim because it was satisfied that trial counsel's objections had preserved the claimed error in the testimony. The court also held that the expert witness testimony was appropriate. Bynum appealed. The Court of Appeals reversed Bynum's convictions in an unpublished opinion per curiam. The Supreme Court held that if the prosecution presents fact evidence to show that the crime at issue is gang-related, expert testimony about gangs, gang membership, and gang culture may be admitted as relevant under MRE 402 and of "assist[ance] [to] the trier of fact to understand the evidence or to determine a fact in issue" under MRE 702. In applying MRE 402 and MRE 702 to the facts of this case, the Supreme Court concluded the trial court appropriately exercised its role as gatekeeper in determining that expert testimony about gangs and gang culture would assist the jury in understanding the evidence. The Court also held that MRE 404(a) precludes testimony that is specifically used to show that, on a particular occasion, a gang member acted in conformity with character traits commonly associated with gang members. The expert witness in this case exceeded these limitations when he provided his opinion that defendant committed the crimes at issue because he acted in conformity with his gang membership. The Court therefore affirmed the result of the Court of Appeals and remanded this case to the Circuit Court for a new trial.
