In the case of Gulf, Colorado and Santa Fe Railway Company v. Hefley in 1894, the U.S Supreme Court ruled on a dispute involving land ownership rights. The railway company had been granted certain lands by Congress to aid in its construction but later sold some of these lands to private individuals including Hefley. However, it was discovered that part of this land was within an Indian reservation which Congress did not have authority over at the time when they were given to the railway company. Thus, those sales were deemed invalid as per federal law governing such transactions with Native American tribes' lands without their consent or treaty provisions allowing for such transfers. The court held that even though Hefley bought his parcel in good faith from the railroad company before discovering its status as part of an Indian reservation; he could not claim title because it never legally belonged to either him or the railroad company due to lack of Congressional authority over tribal reservations during that period. This decision reinforced legal protections for Native American tribal territories against unauthorized encroachments and affirmed principles regarding property rights under Federal law.

In the dissenting opinion for Gulf, Colorado and Santa Fe Railway Company v. Hefley (1894), Justice Brewer argued that the majority's decision was inconsistent with previous rulings of the court. He contended that it was not within a state's power to regulate interstate commerce rates, as this authority belonged exclusively to Congress under the Commerce Clause of the Constitution. Furthermore, he disagreed with their interpretation of "reasonable" rates set by states on railroads operating within their borders; in his view, these should be determined by market forces rather than legislative action. He also expressed concern about potential harm to railroad companies from arbitrary rate-setting by individual states without federal oversight or consistency across jurisdictions.
