Robert H. Jackson, Champlin Refining Company v. United States…
“ The power of Congress to regulate interstate commerce is not dependent on the technical common carrier status but is quite as extensive over a private carrier. This power his yet been invoked only to the extent of requiring Champlin to furnish certain information as to facilities being used in interstate marketing of its products. The commerce power is adequate to support this requirement whether appellant be considered a private carrier or a common carrier. ”
