Knowlton v. Watertown and Spalding v. Watertown were two Supreme Court cases that were decided together in 1875. The cases involved the question of whether a municipality could be held liable for damages caused by a defective bridge. In Knowlton, the plaintiff was injured when his horse and wagon fell through a bridge that had been negligently constructed by the town of Watertown. In Spalding, the plaintiff was injured when his horse and wagon fell through a bridge that had been negligently maintained by the town of Watertown. In both cases, the Supreme Court held that the town of Watertown was liable for the damages caused by the defective bridges. The Court reasoned that the town had a duty to maintain the bridges in a safe condition, and that it had breached that duty by failing to do so. The Court also held that the town was liable for the damages even though it had not been negligent in constructing the bridges. This ruling established the principle that municipalities can be held liable for damages caused by defective public works.

The dissenting opinion in the case of Knowlton v. Watertown and Spalding v. Watertown was written by Justice Story, who argued that the majority’s decision to uphold a tax on real estate violated the Constitution’s prohibition against direct taxation without apportionment among states according to their population. He noted that while it may be true that such taxes are necessary for public purposes, they must still comply with constitutional requirements or else they will be deemed unconstitutional. Furthermore, he argued that if Congress were allowed to impose such taxes without regard for state populations then it would effectively grant them unlimited power over taxation which is not what the framers intended when drafting the Constitution. In conclusion, Justice Story believed that since this particular tax did not meet these criteria it should have been declared unconstitutional and thus overturned by the court
