The case Cincinnati, Indianapolis & Western Railroad Company v. Indianapolis Union Railway Company et al., 1925 revolved around the dispute over railroad track usage rights in Indiana. The plaintiff, Cincinnati, Indianapolis & Western Railroad (CI&W), argued that it was being unfairly denied access to certain tracks owned by the defendants - namely, the Cleveland, Cincinnati, Chicago and St. Louis Railway; Pittsburgh, Cincinnati Chicago and St Louis Railway; and Indianapolis Union Railway Companies. CI&W claimed this denial violated its contractual rights as well as federal law under the Sherman Anti-Trust Act due to alleged monopolistic practices by these companies. However,the Supreme Court ruled against CI&W stating that there was no violation of either contract or anti-trust laws because CI&W had not demonstrated any actual injury resulting from their inability to use those specific tracks nor did they provide evidence showing a conspiracy among defendant railroads for monopolization.

The dissenting opinion in the case of Cincinnati, Indianapolis & Western Railroad Company v. Indianapolis Union Railway Company et al., argued that the majority's decision to uphold an order by the Interstate Commerce Commission (ICC) was incorrect. The ICC had ordered a reduction in terminal charges for certain railroads using facilities at Indianapolis, which were owned and operated by another railroad company. The dissenting justices believed this constituted government overreach into private business matters and violated principles of fairness as it forced one company to subsidize others' operations without receiving adequate compensation itself. They also expressed concern about potential negative impacts on future investments in railway infrastructure due to fears of similar regulatory interference.
