Matthew Liebman is Director of Litigation in the litigation program and works on all aspects of ALDF’s civil cases. He has litigated cases including ALDF v. Otter, the first lawsuit to successfully invalidate an Ag-Gag law; Bennett v. McDaniel, which rescued a captive bear from a small concrete cage where she had languished for 16 years; and ALDF v. Conyers, which resulted in the rescue of more than 100 dogs from a North Carolina hoarder. Matthew’s writing has appeared in the Animal Law Review, the Journal of Animal Law, the Stanford Environmental Law Journal, and the Animal Legal & Historical Web Center. With Bruce Wagman, Matthew co-authored A Worldview of Animal Law, which examines how the legal systems of different countries govern our interactions with animals.
Before coming to ALDF, Matthew clerked for the Honorable Warren J. Ferguson of the United States Court of Appeals for the Ninth Circuit. Matthew graduated with distinction from Stanford Law School in 2006 and with highest honors from the University of Texas at Austin in 2001 with a degree in philosophy. While a law student at Stanford, Matthew co-founded a chapter of the Student Animal Legal Defense Fund and was an active member of Animal Rights on the Farm, where he worked on campaigns against factory farming and vivisection. He lives with his human companion and their five feline companions Kitty Kitty, Ollie, Emma, Spider, and Niecey.
Chris Berry works on a broad range of animal issues including puppy mills, factory farms, and consumer rights. He helps formulate creative legal theories to help animals and challenges government agencies that are not following the law as in Legal Rights and Duties in Lost Pet Disputes. Chris also works hard to fight abuse on factory farms and protect consumers who want to make humane choices. For example, Chris served on the Cal-Cruz Hatcheries case, applying the animal cruelty code to a chicken hatchery through a consumer protection law. Chris also worked on Glover v. Mahrt, a class-action lawsuit alleging that egg packaging depicting outdoor hens mislead consumers who wanted to buy more humanely produced eggs.
Chris graduated with honors in 2008 from the University of South Dakota, where he majored in political science and minored in psychology. While there, he focused his attention on animal issues and wrote an honors thesis arguing that invasive medical testing on animals violates fundamental bioethics principles. Chris attended law school at the University of Michigan while maintaining his interest in animal rights with a focus on litigation. Chris was involved in student advocacy in Ann Arbor and acquired experiences interning at the public defender’s office in the child abuse and neglect docket, participating in the environmental law clinic, and serving as a law clerk for the Humane Society of the United States, where he worked on the farmed animal litigation team. Chris cares for two sweet lab mixes and watches out for his roommate’s goofy Rottweiler.
