In the McClaine v. Rankin case of 1904, the United States Supreme Court ruled on a dispute involving mining rights in Colorado. The plaintiff, McClaine, claimed that he had been unlawfully dispossessed of his mining claim by the defendant, Rankin. He sought to regain possession and recover damages for ore removed from the mine by Rankin during his period of control over it. However, there was disagreement about whether or not McClaine's original claim complied with federal law requirements for establishing a valid mining claim. The Supreme Court held that under federal law governing mineral lands in public domain states like Colorado at that time (the Mining Act), an individual could establish a valid mining claim only if they discovered valuable minerals on unclaimed land and properly marked their boundaries according to statutory requirements. The court found insufficient evidence showing that these conditions were met when McClain made his initial discovery and staked out his claims; therefore ruling against him. This decision underscored how important compliance with legal formalities is when asserting property rights over natural resources.

The dissenting opinion in the McClaine v. Rankin case argued that the majority's decision to uphold a lower court ruling, which held McClaine liable for damages caused by his negligence while operating a train, was incorrect. The dissent believed that this interpretation of liability law unfairly penalized individuals who were simply doing their jobs and could not reasonably foresee or prevent all potential accidents. They contended that such an expansive view of liability would have negative consequences for businesses and workers alike, potentially stifling economic growth and innovation due to fear of legal repercussions. Furthermore, they disagreed with the majority's assertion that McClaine had been negligent in his duties as a train operator; instead arguing he had acted appropriately given the circumstances at hand.
