In the United States v. Winchester and Potomac Railroad Company case of 1895, the U.S. Supreme Court ruled in favor of the government, asserting its right to regulate interstate commerce under Article I, Section 8 of the Constitution. The dispute arose when Winchester and Potomac Railroad Company refused to comply with a federal law requiring them to report their earnings annually for taxation purposes. The company argued that this requirement was an infringement on their rights as it involved intrastate business activities which were beyond federal jurisdiction. However, the court held that since railroads are instrumentalities of interstate commerce, they fall within Congress's regulatory power even if some aspects involve intrastate operations.

The dissenting opinion in the case of United States v. Winchester and Potomac Railroad Company argued that the majority's decision was incorrect because it failed to consider the nature of a railroad as a public highway, which is subject to governmental regulation. The dissenters believed that railroads are not merely private property but also serve an important public function, thus making them different from other types of private property. They contended that when Congress granted land for construction of railroads, it did so with the understanding that these would be used for public benefit and could therefore be regulated by government authorities. Therefore, they disagreed with the majority's ruling which held otherwise - stating instead that such lands were given without any implied right to regulate rates or services provided by those companies on their own properties.
