The Right to Rescue
If a dog is being tortured behind closed doors — if its vocal cords have been cut without anesthesia, if it has never seen sunlight — do you have the right to carry it out? The law says no. This movement says the law is wrong.
The Necessity Defense in Animal Rescue
If you break into a burning building to save a child, no jury convicts you for trespass. The legal principle is necessity — the harm prevented outweighs the harm caused. The Right to Rescue movement applies this logic to animals: if documented, ongoing cruelty is causing severe suffering, and authorities have failed to act, then entering a facility to remove suffering animals is a lesser harm than leaving them.
The legal reality is stark: no US court has ever formally permitted the necessity defense in an animal rescue prosecution. Every trial court that has ruled on the question has rejected it. Yet juries have acquitted defendants in two of five completed trials, and prosecutors have dropped charges in several others. The law says no; juries keep saying yes.
The Legal Status
The necessity defense in animal rescue exists in a paradox. On paper, it has never succeeded: no appellate court has endorsed it, no trial judge has allowed a jury to consider it without restriction, and the legal establishment treats it as settled — animals are property, and property interests do not ground necessity.
But the courtroom reality tells a different story. When jurors are confronted with evidence of animal suffering — even when the judge has formally rejected the necessity defense and instructed them to disregard it — they acquit. The Circle Four Farms trial (October 2022) produced the first jury acquittal for open rescue in US history. The Foster Farms truck trial (March 2023) produced the second. In both cases, the necessity defense was legally unavailable. The juries applied it anyway.
Prosecutors have also recognized this dynamic. In the Ridglan Farms beagle case, all charges were dismissed in March 2024 — reportedly because the facility did not want its conditions exposed at trial. In the Iowa Select Farms case, the company itself requested dismissal. The pattern is consistent: facilities that face the prospect of a public trial often prefer to drop charges rather than defend their practices before twelve citizens.
The Four Elements of Necessity
To invoke necessity, a defendant must establish all four elements. Courts have used each as a basis for rejection. Click to expand.
Three Ways Courts Reject It
When the necessity defense is raised in animal rescue prosecutions, courts apply one or more of these rationales to exclude it.
"Humans Only"
Courts hold that necessity exists to prevent harm to people, not animals. Under this rationale, animals are property, and property cannot be a "victim" whose interests justify criminal conduct. This is the most common judicial basis for exclusion.
Applied in People v. Hsiung (Sonoma, 2023) and State v. Hsiung (North Carolina, 2021).
"Legal Alternatives Existed"
Even if animal suffering is real, defendants should have called law enforcement, contacted the USDA, filed complaints, or pursued civil litigation. Courts treat the existence of any theoretical legal channel as fatal to the defense — regardless of whether those channels actually work. In the Ridglan case, rescuers sent 983 emails to the DA over six years. Courts still characterize these alternatives as "available."
Applied in virtually every case where necessity has been raised.
"Legislative Prerogative"
Expanding necessity to cover animal rescue is a policy decision for the legislature, not the judiciary. Courts position themselves as institutionally unable to weigh animal welfare against property rights without democratic authorization. The irony: legislatures point to courts for guidance, creating the circularity problem described below.
Articulated most clearly in the North Carolina and Sonoma County proceedings.
The Vehicle Exception: 16 States
While courts refuse to recognize necessity for facility rescues, sixteen states have enacted statutes granting civilians immunity for breaking into vehicles to rescue animals in distress — so-called "hot car" laws. These laws establish a principle that the Right to Rescue movement argues is directly transferable: animal suffering can justify property interference.
The legal structure of hot car laws mirrors necessity exactly: the rescuer must have a reasonable belief that the animal is in imminent danger, must have attempted to contact law enforcement first, and must use no more force than necessary. The only distinction is the location — a car versus a facility. The suffering is the same. The moral logic is the same. The law treats them as categorically different.
Oregon: The Lone Precedent
Oregon is the only state whose case law explicitly includes animals within the necessity framework. In State v. Haley (1983), the Oregon Court of Appeals recognized that harm to animals could, in principle, satisfy the necessity defense's requirement of an imminent harm to be prevented.
The significance of Haley is doctrinal rather than practical: the court did not acquit the defendant, and the holding has not been widely followed. But it remains the only reported US appellate decision that does not categorically exclude animals from necessity analysis. Every other jurisdiction that has addressed the question has held — explicitly or implicitly — that necessity applies only to the prevention of harm to humans.
Oregon's broader animal law ecosystem is consistent with this position. The state has among the strongest anti-cruelty statutes in the nation, recognizes animals as sentient beings in some statutory contexts, and has been receptive to expanding legal protections for animals. The Haley decision fits a pattern of Oregon leading on animal welfare jurisprudence.
The Pending Appeal: People v. Hsiung
The most consequential pending case for the Right to Rescue is People v. Hsiung, now before California's First Appellate District (Case No. A169697). Wayne Hsiung was convicted in November 2023 in the Sonoma County trial involving rescues from Sunrise Farms (chickens) and Reichardt Duck Farm (ducks). The trial court rejected the necessity defense.
The appeal directly challenges the exclusion of necessity. If the appellate court holds that the trial judge erred in barring the defense — even if it remands for a new trial rather than acquitting — the decision would be the first published appellate opinion in any US jurisdiction to hold that animal suffering can ground a necessity claim in a facility-entry case. It would reshape the doctrine nationwide.
Separately, Zoe Rosenberg was convicted in October 2025 for rescues from Petaluma Poultry (a Perdue facility). She filed her own appeal on December 3, 2025. Both appeals raise overlapping issues and may be consolidated or decided in sequence.
The Circularity Problem
The legal status of necessity in animal rescue is trapped in a self-reinforcing loop. Legislatures have not enacted animal-rescue necessity provisions because courts have not recognized the defense — and there appears to be no judicial consensus that such a right exists. Courts decline to recognize the defense because legislatures have not acted — and expanding necessity to cover animals is characterized as a "legislative prerogative."
Each branch points to the other. Neither moves. Meanwhile, the 16 hot car statutes demonstrate that legislatures are willing to authorize animal rescue when the context is sympathetic enough — they simply have not extended the principle beyond vehicles. And the two jury acquittals demonstrate that citizens do recognize the moral logic of necessity — they simply lack a legal framework to formalize it.
The Right to Rescue movement's legal strategy is to break this loop through accumulated pressure: jury acquittals that signal public support, appellate decisions that crack the doctrinal wall, and legislative campaigns that build on both. The Hsiung appeal is the current focal point. If it succeeds, the circularity dissolves.
