The United States Supreme Court case, UNITED STATES v. INTERSTATE COMMERCE COMMISSION ET AL., 1948, revolved around the Interstate Commerce Commission's (ICC) decision to approve increased freight rates for railroads in the western part of the country. The U.S government challenged this decision on grounds that it was discriminatory against shippers located in other parts of the nation and thus violated federal law which required uniformity in rate increases across all regions. However, ICC defended its action by arguing that these higher rates were necessary due to unique operating conditions and costs faced by western railroads. The Supreme Court ruled in favor of ICC stating that while federal law did require uniformity generally, it also allowed for exceptions when justified by special circumstances or conditions such as those presented here.

In the dissenting opinion for United States v. Interstate Commerce Commission et al., Justice Robert H. Jackson argued that the majority's decision to uphold an order of the Interstate Commerce Commission (ICC) was a misinterpretation of both legislative intent and statutory language. He contended that Congress had not intended to give such broad authority to ICC, especially in matters concerning rates set by rail carriers for military transportation services during wartime periods. According to him, this power should be vested with Congress itself or at least with an agency directly responsible for war logistics like War Department rather than ICC which is primarily concerned with civilian commerce regulation. Furthermore, he expressed concerns about potential abuses of unchecked administrative powers and stressed on judicial responsibility in interpreting statutes so as not to overstep constitutional boundaries between different branches of government.
