In County of Ray v. Vansycle, the Supreme Court of the United States was asked to decide whether a county could be held liable for damages caused by a defective bridge. The plaintiff, Vansycle, had been injured when his horse and wagon fell through a bridge that had been built by the county. Vansycle argued that the county was liable for his injuries because the bridge was defective and the county had failed to maintain it. The Supreme Court held that the county was not liable for Vansycle's injuries. The Court reasoned that the county was not liable because it had not been negligent in constructing or maintaining the bridge. The Court noted that the county had acted in good faith and had not been aware of any defects in the bridge. Furthermore, the Court held that the county was not liable because it had not been negligent in constructing or maintaining the bridge. The Court's decision in County of Ray v. Vansycle established that a county cannot be held liable for damages caused by a defective bridge unless it was negligent in constructing or maintaining the bridge. This decision has been cited in numerous cases since then, and it remains an important precedent in the area of municipal liability.

Justice Field delivered the dissenting opinion in County of Ray v. Vansycle, arguing that the majority's decision was incorrect and should be reversed. He argued that a county is not legally capable of holding title to real estate; rather, it can only hold such property for public use or benefit as an agent of the state government. Therefore, he reasoned that when a county holds title to land which has been dedicated by its owner for public use or benefit, it does so as an agent of the state and cannot convey any greater right than what was originally held by its grantor. In this case, Justice Field concluded that since there had been no dedication made by Vansycle prior to his death regarding his interest in certain lands located within Ray County’s boundaries, then those lands were still subject to taxation under Missouri law regardless if they were owned by Ray County at one point or another. As such, he believed that taxes could lawfully be imposed on these properties without violating either federal or state laws and thus disagreed with the majority's ruling against taxing them accordingly.
