Amicus Brief in Hardy v. United States Trails Act Taking Case
On November 6, 2019, True North Law filed an amicus brief in the U.S. Court of Appeals for the Federal Circuit on behalf of property rights organizations and a prominent legal scholar in support of Georgia landowners whose land was taken by the federal government for a public recreational rail-trail. The Cato Institute, Southeastern Legal Foundation, National Association of Reversionary Property Owners, and Professor of Property Law James W. Ely asked True North to file a brief on their behalf supporting these Georgia landowners.
The government wants to deny these landowners the compensation they are guaranteed by the Fifth Amendment. The government is arguing that the landowners didn’t actually own their land and that, even if they did own their land, the new use of their land for a new public recreational trail is consistent with the former “railroad” use.

Thor Hearne has earned a national reputation for his work in complex federal and state litigation and appeals, especially matters involving property rights, constitutional law, and election issues. Thor has represented more than 1,000 landowners in federal property rights litigation arising under the Trails Act.
Thor was named one of the nation’s top Fifty Litigation Trailblazers and Pioneers by the National Law Journal and was also featured in the National Law Journal as a pre-eminent national trial and appellate attorney for his work in property rights litigation. Thor has been named a Super Lawyer in both Washington DC and in Missouri by the peer-rating system and Thor has been given the highest AV rating by Martindale-Hubbell.
Thor was elected to membership in the prestigious, invitation-only Owners’ Counsel of America association of property-rights lawyers. Only one lawyer from each state and the District of Columbia is admitted to Owners’ Counsel of America which is an organization of the most distinguished property-rights and eminent domain attorneys in the nation.
Thor has enjoyed success as the lead counsel in numerous federal and state trials including jury trials and bench trials. Thor’s courtroom successes have made him a frequent and highly sought-after speaker at national legal conferences, including the Brigham-Kanner Property Rights Conference at William & Mary Law School, where he serves as a member of the Advisory Council. Thor has spoken internationally at property rights and property law. Thor addressed international property law and property rights conferences at Tsinghua University School of Law in Beijing China and the Universiteit Leiden at The Hague in the Netherlands.
For almost a decade Thor has served as a faculty member on the American Law Institute Eminent Domain and Land Valuation Litigation Conference. Thor was chosen by the judges of the U.S. Court of Federal Claims to serve on the Court’s Advisory Council and takings committee.
In similar property rights litigation, Thor represented the Culverhouse family in the precedent-setting decision against the Internal Revenue Service that Thor argued and won in the Eleventh Circuit Court of Appeals. The case involved the IRS’s attempt to challenge the value of that property the Culverhouse family donated for the Culverhouse Nature Park and Community Garden. The Culverhouse decision established a national precedent favoring property owners who donate property for a conservation easement like the one the Culverhouse family donated to Sarasota. Hearne is also appellate counsel for property owners in two pending Florida pipeline condemnation cases that will be heard by the Eleventh Circuit this summer.
Those following the Supreme Court’s property rights decisions are familiar with Thor’s experience and work in constitutional and property rights litigation. Hearne was lead counsel for a number of amici curiae (friends of the court) in several of the Supreme Court’s most consequential property rights decisions. This includes American Farm Bureau Foundation, Cattleman’s Beef Association, American Land Title Association, Public Lands Council, Southwestern Legal Foundation, Pacific Legal Foundation, Cato Foundation, Montana Farm Bureau Foundation, National Federation of Independent Businesses Small Business Foundation, National Association of Reversionary Property Owners, Save our Shoreline and property law professors and scholars, James Ely, Jr. Richard Epstein, Dale Whitman and Donald Kochan, among others.
Thor argued a constitutional challenge to the State of Arizona redistricting statute before the United States Supreme Court and was supported in the argument by Arizona’s Attorney General. Thor has argued other constitutional and property rights challenges before various state supreme courts including the Florida, Michigan, Missouri and Kansas supreme courts and a number of lower appellate courts. The Commonwealth of Virginia retained Thor to be Virginia’s lead trial and appellate counsel defending Virginia against a constitutional challenge to the commonwealth’s election laws. Thor and Virginia prevailed in both trial court and with a unanimous decision in favor of Virginia in the U.S. Court of Appeals for the Fourth Circuit.
Publications
Thor has written a number of law reviews and other articles on property rights and constitutional law. The American Bar Association asked Thor to write one of the leading articles on the Trails Act. “The Trails Act: Railroading Property Owners and Taxpayers for More Than a Quarter Century,” Real Property, Trust and Estate Law Journal, Vol. 115, Spring 2010. And, “The Fifth Amendment Requires the Government to Pay an Owner Interest Equal to What the Owner Could Have Earned Had the Government Paid the Owner the Fair-Market Value of Their Property on the Date the Government Took the Owner’s Property,” Brigham-Kanner Property Rights Conference Journal, Vol. 1, September 2012.

Life Beyond the Law
Thor is a private pilot and sailor. In the summer, he and his family enjoy any opportunity they have to escape to Northern Michigan, where Thor grew up in the summer. Thor and his brother are active in efforts to preserve the unique character of the last undeveloped beach–front property in their northern Michigan community. Part of this effort included Thor writing the Supreme Court amicus brief in support of a writ of certiorari in Gunderson v. State of Indiania.

She has a deep understanding and empathy for the farm families throughout the United States that have had their farms and properties taken by the Government – many properties being in families for many generations.
What we do is very important to me personally, especially since all we can do to bring these families justice they are legally entitled to for the Government’s taking of their property, is to represent them in the Court of Federal Claims in Washington DC. A Court that Congress specifically developed for this particular issue.
