In the case of Casey v. Cavaroc, the Supreme Court of the United States was asked to decide whether a contract between two parties was valid and enforceable. The contract in question was between a man named Casey and a woman named Cavaroc. Cavaroc had agreed to pay Casey a certain sum of money in exchange for a piece of land. However, Cavaroc failed to make the payment and Casey sued her for breach of contract. The Supreme Court held that the contract was valid and enforceable. The Court noted that the contract was in writing and that both parties had agreed to its terms. Furthermore, the Court found that the contract was not against public policy and that it was not unconscionable. As such, the Court held that Cavaroc was liable for breach of contract and ordered her to pay the agreed-upon sum of money to Casey.

Justice Field delivered the dissenting opinion in Casey v. Cavaroc, arguing that the majority's decision was contrary to established precedent and would lead to confusion among lower courts. He argued that under prior decisions of the Supreme Court, a party who had been wrongfully deprived of their property could not be held liable for damages caused by another person taking possession of it without authority from either party. In this case, Cavaroc had taken possession of Casey's land without any authorization from either him or his agent; thus he should not have been held responsible for any damage done while in possession. Furthermore, Justice Field noted that even if Cavaroc were found liable for some portion of the damages suffered by Casey due to his wrongful occupation, there was no evidence presented at trial which showed how much money he should be required to pay as compensation. As such, Justice Field concluded that it was improper for the court to award an amount greater than what could reasonably be expected based on all available evidence and urged reversal of its judgment against Cavaroc so as not to create uncertainty amongst future cases involving similar facts and circumstances.
