People of Mi v. Micheline Nicole Leffew

Summary

The Michigan Supreme Court held that the common‑law defense of others is available as an affirmative defense to both the non‑assaultive home‑invasion charge and the felonious‑assault charge, that counsel’s failure to request a defense‑of‑others jury instruction was objectively unreasonable under Strickland, and that the omission prejudiced the defendants, warranting reversal and a new trial.
