In the case of United States et al. v. N.E Rosenblum Truck Lines, Inc., 1941, the U.S Supreme Court ruled in favor of the government's right to regulate interstate commerce and transportation rates under its constitutional powers. The court held that a trucking company engaged in interstate commerce was subject to federal regulation even if it operated within one state only because its activities affected overall national commercial interests. This decision reinforced Congress' power under the Commerce Clause of the Constitution to regulate all aspects of interstate trade including intrastate activities which have a substantial effect on such trade.

In the dissenting opinion for United States et al. v. N.E Rosenblum Truck Lines, Inc., Justice Roberts argued that the majority's decision to uphold an order of the Interstate Commerce Commission (ICC) was incorrect because it violated principles of due process. He contended that by allowing ICC to fix rates without a hearing or evidence, and solely based on its own investigations and reports, it denied carriers their right to challenge these determinations in court before they were enforced. This lack of judicial review prior to enforcement constituted a violation of constitutional rights according to Justice Roberts' interpretation. Furthermore, he disagreed with the majority's view that Congress had intended such procedures when drafting relevant legislation; instead asserting that lawmakers would not have knowingly sanctioned such disregard for basic legal protections.
