Twin-Lick Oil Company v. Marbury is a United States Supreme Court case that was decided in 1875. The case involved a dispute between Twin-Lick Oil Company and Marbury, a former employee of the company. Marbury had been employed by Twin-Lick Oil Company for several years and had been promised a bonus for his services. When the company refused to pay the bonus, Marbury sued for breach of contract. The Supreme Court ruled in favor of Marbury, finding that Twin-Lick Oil Company had breached its contract with Marbury. The Court held that Marbury was entitled to the bonus he had been promised and that Twin-Lick Oil Company was liable for damages. The Court also held that Marbury was entitled to interest on the amount of the bonus. The case is significant because it established the principle that a contract must be enforced according to its terms. This principle has been applied in numerous cases since then, and it is still an important part of contract law today. The case also established the principle that a party who breaches a contract is liable for damages, including interest on the amount of the bonus. This principle has also been applied in numerous cases since then.

In the case of Twin-Lick Oil Company v. Marbury, Justice Field delivered a dissenting opinion in which he argued that the court should not have heard the case at all. He believed that it was an issue between two private parties and did not involve any federal question or constitutional right, so it was outside of the jurisdiction of this court. Furthermore, he argued that even if there had been some federal element to consider, then under existing law Congress would need to pass legislation granting authority for such a suit before this Court could hear it. As no such legislation existed in this instance, Justice Field concluded that the Court lacked jurisdiction over Twin-Lick Oil Company's complaint against Marbury and thus should have dismissed it without reaching any decision on its merits.
