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.

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.
