Kearney v. Case was a United States Supreme Court case that dealt with the issue of whether a contract between two parties was valid. The case involved a contract between Kearney and Case, in which Kearney agreed to pay Case a certain amount of money for the use of a certain piece of property. Case argued that the contract was valid, while Kearney argued that it was not. The Supreme Court ultimately ruled in favor of Case, finding that the contract was valid. The Court held that the contract was binding and enforceable, and that Kearney was obligated to pay the amount specified in the contract. The Court also held that the contract was not voidable due to any lack of consideration, as the consideration was sufficient to make the contract valid. The Court's decision in Kearney v. Case established that contracts between two parties are binding and enforceable, and that consideration is not necessary for a contract to be valid. This decision has been cited in numerous subsequent cases, and has been used to establish the validity of contracts in a variety of contexts.

In the case of Kearney v. Case, Justice Field delivered a dissenting opinion that argued in favor of the plaintiff's right to sue for damages caused by an illegal act. He reasoned that if Congress had intended to deny such rights, it would have done so explicitly and not left it up to interpretation. Furthermore, he stated that denying individuals their right to seek redress for wrongs committed against them was contrary to public policy and could lead people into taking matters into their own hands instead of relying on legal remedies provided by the government. In conclusion, Justice Field believed that allowing citizens access to courts was essential in order for justice and fairness prevail within society.
