In the case of Garneau v. Dozier, the Supreme Court of the United States was asked to determine whether a contract between two parties was valid and enforceable. The contract in question was between Garneau, a Louisiana resident, and Dozier, a Mississippi resident. The contract stated that Garneau would pay Dozier a certain sum of money in exchange for Dozier's promise to convey certain real estate to Garneau. The Supreme Court held that the contract was valid and enforceable. The Court noted that the contract was made in good faith and that both parties had the capacity to enter into the contract. Furthermore, the Court found that the contract was not against public policy and that it was not in violation of any state or federal laws. The Court also held that the contract was binding on both parties and that Garneau was entitled to the real estate that was promised to him. The Court noted that Dozier had breached the contract by failing to convey the real estate to Garneau and that Garneau was entitled to damages for the breach. In conclusion, the Supreme Court held that the contract between Garneau and Dozier was valid and enforceable and that Garneau was entitled to damages for Dozier's breach of the contract.

In the case of Garneau v. Dozier, the Supreme Court was tasked with determining whether a contract between two parties that had been partially performed could be enforced by one party against another. The majority opinion held that it could not, as there was no consideration to support such an action. However, Justice Field dissented from this decision and argued that when a contract has already been partially performed by both parties then it should be enforceable in court even if there is no additional consideration provided for its enforcement. He reasoned that since each party had already done something under the agreement they were obligated to fulfill their respective duties regardless of any further considerations being given or received. Furthermore, he noted that allowing contracts which have been partially fulfilled to remain unenforceable would lead to injustice and encourage dishonesty among those who enter into agreements without intending on fulfilling them fully once some benefit has already accrued from them.
