In the 1923 case of United States and Interstate Commerce Commission v. Abilene & Southern Railway Company et al., the Supreme Court ruled in favor of the government, upholding its authority to regulate interstate commerce. The dispute arose when several railway companies challenged an order by the Interstate Commerce Commission (ICC) that required them to cease discriminatory pricing practices against certain shippers. The railways argued that they were not engaged in interstate commerce as defined under federal law because their operations were confined within Texas state lines, even though they connected with other railroads for longer hauls across state borders. The Supreme Court disagreed with this interpretation, ruling that a shipment which starts at one point and ends at another through continuous transportation is considered interstate commerce regardless of where it crosses state lines or changes carriers along its route. Therefore, such shipments fell under ICC's jurisdiction and could be regulated accordingly. This decision affirmed federal power over all aspects of interstate trade including intrastate segments if part of a larger inter-state journey.

In the dissenting opinion for the case between United States and Interstate Commerce Commission v. Abilene & Southern Railway Company, it was argued that the court majority had overstepped its jurisdiction by intervening in a matter of administrative discretion. The dissenting justices believed that it was not within their purview to question or review decisions made by an independent regulatory agency like the Interstate Commerce Commission (ICC), unless there were clear violations of constitutional rights or statutory provisions. They contended that ICC's decision to allow certain railroads to increase freight rates should be respected as part of its mandate to regulate interstate commerce and ensure fair competition among carriers. Furthermore, they warned against judicial intrusion into economic policy-making, which could undermine public confidence in both institutions and disrupt market stability.
