Director of Public Prosecutions v. Camplin

After being sexually assaulted and then mocked by an adult man, 15-year-old Camplin (defendant) struck and killed his attacker with a kitchen pan and raised provocation to reduce his murder charge to manslaughter, but the trial court instructed the jury to consider only whether a reasonable adult man in like circumstances would have reacted as Camplin did; the court of appeal found that instruction erroneous and substituted a manslaughter conviction, and the House of Lords agreed to review.
