Litigation – List of Cases

Filing High Impact Lawsuits that Expand the Protections for Animals Under the Law

The Litigation Program files high-impact lawsuits against individuals and industries that exploit animals, including factory farms, puppy mills, research laboratories, and roadside zoos. We litigate cases in state and federal courts with the goal of stopping abusive practices and setting ground-breaking precedent that will establish justice for animals in the legal system. In addition to suing animal abusers, we often sue state and federal governments and agencies to invalidate laws and regulations that harm animals; and we intervene in litigation to defend animal protection laws when they are under siege from industries that abuse animals.
