In the 1892 case of Barnett v. Kinney, the United States Supreme Court dealt with a dispute over land ownership in California. The plaintiff, Barnett, claimed that he had purchased a piece of property from an individual who had acquired it through preemption rights under federal law. However, the defendant, Kinney, argued that he was actually the rightful owner because he had received a patent for this same land from the state of California before Barnett's purchase took place. The court ruled in favor of Kinney on grounds that his patent held precedence over any subsequent claims to ownership based on preemption rights or other means. This decision reinforced states' authority and autonomy regarding their own public lands against potential conflicts with federal laws or policies.

In the dissenting opinion for Barnett v. Kinney, it was argued that the majority's decision to uphold a tax on out-of-state insurance companies doing business in Nebraska violated the Constitution's Commerce Clause. The dissent contended that this tax constituted an unfair burden on interstate commerce and therefore exceeded state authority. They believed that such taxation should be uniform across all states to prevent discrimination against businesses from other states, which they saw as contrary to the spirit of free trade among states enshrined in the Constitution. Furthermore, they disagreed with characterizing these taxes as mere fees for corporate privileges granted by Nebraska; instead viewing them as direct impositions on interstate transactions themselves - something beyond state purview according to their interpretation of federal law and precedent.
