Senior Attorney, Pacific Legal Foundation
Damien Schiff is a senior attorney at Pacific Legal Foundation. He leads its environmental practice group, a unique initiative that draws broadly from PLF’s expertise and success in property rights and separation of powers litigation. Over the years, Damien has represented hundreds of landowners and property rights advocates to defend their liberties against heavy-handed and unwarranted environmental and land-use regulation. His litigation experience includes Sackett v. U.S. Environmental Protection Agency, a groundbreaking decision in which the U.S. Supreme Court upheld the right of landowners to challenge Clean Water Act compliance orders issued by EPA, and Contoski v. Norton, PLF’s successful effort to force the federal government to make good on its promise to delist the bald eagle from the Endangered Species Act.
Besides litigation, Damien has written academic articles on a variety of subjects, including the Endangered Species Act, the Clean Water Act, greenhouse gas torts, the duty to rescue, and international water law. He has appeared on a variety of television and radio programs and has been quoted in The New York Times, The Wall Street Journal, Harper’s Magazine, and The Economist, among other publications.
He obtained his law degree magna cum laude from the University of San Diego School of Law, and his undergraduate degree magna cum laude from Georgetown University. While at USD, he was a research assistant for Professor Bernard Siegan, a leading constitutional theorist and advocate for property rights and economic liberty. Immediately prior to joining PLF, Damien clerked for Judge (and former PLF attorney) Victor Wolski of the United States Court of Federal Claims. Damien credits the mentoring and examples of Professor Siegan and Judge Wolski for his decision to pursue a career in liberty-based public interest litigation.
Damien lives in Sacramento with his wife, two young sons, four chickens, and a cat named Princess. In his off hours he enjoys stamp collecting, Gregorian chant, and martinis—preferably at the same time.
