On December 8, 2014, the Supreme Court heard oral argument in Department of Transportation v. Association of American Railroads. The question in this case is whether the Passenger Rail Investment and Improvement Act of 2008 unconstitutionally delegates legislative power to a putatively private entity--Amtrak--by involving it in the creation of standards used to determine whether freight railroads are according the preference to Amtrak’s passenger trains that is required by federal law regarding the use of rail lines. -- To discuss the case, we have Prof. Alexander “Sasha” Volokh, who is an Associate Professor of Law at the Emory University School of Law. Professor Volokh received his JD and PhD in economics from Harvard University.
