People v. Hsiung — Animal Rights Activist’s Trespass Convictions Partially Reversed for Erroneous Limitation on Mistake of Law Defense
First District partially reverses animal rights activist’s trespass convictions arising from open-rescue activities at Sonoma County poultry farms, holding the trial court erred by limiting evidence of the defendant’s good-faith mistake of law about the legality of his conduct under the necessity doctrine, while affirming the misdemeanor trespass conviction and rejecting First Amendment challenges.
