Daniel Woislaw is an attorney with the Institute for Justice where he focuses on securing Americans’ rights against government overreach, especially as it relates to private property.
Prior to joining IJ, Daniel worked for several years as an attorney at the Pacific Legal Foundation, arguing property cases in state and federal courts across the country. Before that, he served as a public defender in Virginia, where he litigated several hundred cases on behalf of indigent adult and juvenile defendants who could not afford a private attorney.
In addition to his litigation work, Daniel writes and speaks regularly on constitutional issues, including government regulations of private property, the Fifth Amendment’s Just Compensation Clause, immunity doctrines, and the Fourth Amendment’s guarantee of the right to be secure against unreasonable searches and seizures.
Daniel is also an affiliated privacy scholar with the Libertas Institute. He graduated magna cum laude from The Antonin Scalia Law School at George Mason University and holds a B.S. in business administration from Suffolk University.
Outside the courtroom, Daniel is an avid board game enthusiast and spends an inordinate amount of time experimenting with new recipes in his home kitchen. He lives in Austin, TX with his wife and two daughters.
