FIRST APPELLATE DISTRICT

DIVISION FIVE

THE PEOPLE, Plaintiff and Respondent, A169697 v. WAYNE HANSEN HSIUNG, (Sonoma County Defendant and Appellant. Super. Ct. No. SCR721464)

This appeal relates to the right of a criminal defendant to present a complete defense to the jury, including the right to present evidence regarding the defendant’s misconceptions regarding the legality of his or her conduct when the charged offenses are specific intent crimes. Defendant, Wayne Hansen Hsiung, was convicted on two counts of trespass and one count of conspiracy to commit trespass relating to his involvement in animal rights protests at two Sonoma County poultry farms. On appeal, defendant seeks reversal of these counts, arguing: (1) the trial court prejudicially erred by finding his defense of necessity legally unavailable; (2) the court deprived him of his constitutional right to present a complete defense by refusing to instruct the jury or permit him to present evidence or argument related to his good faith mistake of law that his actions

1 were legally justified under the necessity defense; (3) Penal Code section 31, 1 the aiding and abetting statute on which the jury was instructed, violates the First Amendment to the extent it criminalizes a defendant’s “promotion” of another person’s illegal conduct; (4) section 602, subdivision (o), the basis of count 2, trespass by refusing or failing to leave property, violates the First Amendment as a content-based restriction on speech; (5) the court prejudicially erred by failing to adequately respond to a jury question regarding the meaning of “promote”; and (6) the prosecutor denigrated his de facto religious beliefs in ethical veganism and animal rights to the jury. We reject all these arguments except one. We agree with defendant that the trial court erroneously limited his presentation of evidence to the jury related to his two-prong mistake of law defense. Accordingly, we reverse count 1, conspiracy to commit trespass by refusing to leave private property (§§ 182, subd. (a)(1), 602, subd. (o)), and count 4, trespass with intent to interfere with a lawful business (§ 602, subd. (k)), and remand for further proceedings as to these counts. We affirm the judgment as to count 2 (§ 602, subd. (o)). FACTUAL AND PROCEDURAL BACKGROUND Defendant cofounded a grassroots animal rights network called Direct Action Everywhere, or DxE. Through DxE, defendant and other animal rights advocates engaged in “open rescues,” a nonviolent tactic in which an individual or group concerned about animal suffering enters private commercial property without permission for the purpose of documenting the conditions of animals confined therein and, if necessary, rescues animals deemed to be in urgent need of veterinary care. The advocates then shared information, including photographs and video footage, relating to the

2 conditions found during the rescues with the public and law enforcement in order to address the suspected animal suffering. I. The Amended Information. On September 26, 2023, an amended information was filed charging defendant with felony conspiracy to commit trespass by refusing to leave private property (§§ 182, subd. (a)(1), 602, subd. (o); count 1); misdemeanor trespass by refusing to leave private property (§ 602, subd. (o); count 2); felony conspiracy to commit trespass with intent to interfere with a lawful business (§§ 182, subd. (a)(1), 602, subd. (k); count 3); and misdemeanor trespass with intent to interfere with a lawful business (§ 602, subd. (k); count 4). These charges arose from two open rescue incidents involving defendant and his DxE colleagues at poultry farms in Sonoma County. The first incident took place at Sunrise Farms on May 29, 2018, and the second incident took place at Reichardt Duck Farm on June 3, 2019. II. The Trial. Trial began on September 8, 2023, and lasted several weeks. Defendant represented himself in propria persona. Many witnesses were called, including representatives from Sunrise Farms and Reichardt Duck Farm, DxE activists, local law enforcement officials, legal professionals, and veterinarians. Defendant testified in his own defense. The following evidence was presented. A. Sunrise Farms. Sunrise Farms (Sunrise) is a privately owned commercial egg farm in Sonoma County with a flock of around 800,000 hens as of 2018. Sunrise is not open to the general public.

3 In July 2016, defendant and his DxE colleagues began investigating Sunrise due to concerns that Sunrise was not complying with animal welfare laws. On several occasions, defendant entered Sunrise through unlocked doors and observed animals that he believed were suffering. In photographs and video footage, defendant documented apparently sick, injured, immobile, and severely neglected animals. Defendant shared his information with several individuals, including a veterinarian, Dr. Sherstin Rosenberg, and a criminal law professor, Hadar Aviram. Dr. Rosenberg confirmed to defendant that, in her opinion, the video footage showed severe overcrowding at the farm as well as animals suffering from visible illnesses or injuries that made it difficult for them to access food and water. Professor Aviram agreed. She provided defendant a written opinion on May 17, 2018, offering legal justifications for taking actions to assist the animals at Sunrise. 2 Defendant and his colleagues also took their concerns to state and local law enforcement agencies, including the Sonoma County District Attorney’s Office and Sheriff’s Office. However, the agencies took no action. Ultimately, defendant concluded the only way to address what he considered an “ongoing emergency” at Sunrise was to take more direct action. Accordingly, defendant organized an open rescue on May 29, 2018, the last day of the multiday 2018 Animal Liberation Conference, held in the San

2 As we discuss post, the trial court excluded or limited portions of

Professor Aviram’s testimony regarding the fact that she advised defendant, albeit mistakenly, that he and his colleagues were legally justified in trespassing at Sunrise to prevent animals from suffering imminent harm. The court did, however, permit Professor Aviram to testify regarding her more limited opinion that a statute (§ 597e) authorized them to trespass in order to provide food or water to those animals that had been deprived of food or water for over 12 hours.

4 Francisco Bay Area. During this open rescue incident, defendant and several hundred DxE activists engaged in various forms of protest, including entering private barns, recording and photographing animal conditions, locking people to farm machinery, rescuing animals that appeared to be severely injured or distressed, and holding a candlelight vigil just outside the property. Defendant carried with him Professor Aviram’s written opinion that their actions were legally justified to prevent ongoing animal suffering, as well as his prior photographs and footage reflecting the animals’ condition. Michael Weber, an owner of Sunrise, testified that, when he arrived at the farm during the incident, he told the group to leave, insisting they had no right to be there. Defendant referred him to Professor Aviram’s opinion and insisted their actions were justified. Defendant, with numerous followers, then walked directly passed Weber toward a large barn, despite Weber’s protestations that they posed a biosecurity risk to his animals.
