Kansas Pacific Railway Company, the Supreme Court of the United States was asked to decide whether the United States had the right to take possession of the Kansas Pacific Railway Company's property for the purpose of constructing a military railroad.

The Court noted that the government had the power to take private property for public use, and that the taking of the property was necessary for the public defense and safety.

In United States v. Kansas Pacific Railway Company, the Supreme Court was tasked with determining whether or not a railroad company could be held liable for damages caused by its negligence in failing to maintain an embankment along its tracks. The majority opinion found that the railway company was indeed liable and awarded damages to the plaintiff. However, Justice Field dissented from this decision on two grounds: firstly, he argued that there had been no evidence presented of any negligence on behalf of the railway company; secondly, he contended that even if such evidence had been presented it would have only established liability for gross negligence rather than ordinary negligence as required by law at the time. In conclusion, Justice Field believed that awarding damages under these circumstances would set a dangerous precedent which could lead to unjustified claims against other companies in similar situations.
