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.
