In Jones & Another v. Simpson, 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 an agreement between Jones and Simpson, whereby Jones agreed to pay Simpson a certain sum of money in exchange for a parcel of land. The Supreme Court held that the contract was valid and enforceable. The Court noted that the contract was clear and unambiguous, and that both parties had agreed to its terms. Furthermore, the Court found that the consideration for the contract was sufficient, and that the parties had acted in good faith. The Court also held that the contract was binding on both parties, and that Jones was obligated to pay Simpson the agreed-upon sum of money. The Court noted that the contract was not voidable due to any fraud or misrepresentation, and that Jones was not entitled to any relief from the contract. In conclusion, the Supreme Court held that the contract between Jones and Simpson was valid and enforceable, and that Jones was obligated to pay Simpson the agreed-upon sum of money.

Justice Field delivered the dissenting opinion in Jones & Another v. Simpson, arguing that the majority's decision was wrongfully based on a misconstruction of the law and an incorrect application of its principles. He argued that under California law, where this case originated, it is well established that when two persons are jointly indebted to another person for money or property due from them both as joint debtors, they cannot sue each other for contribution until one has paid more than his proportionate share of such debt. In this case, neither party had yet paid anything towards their joint obligation; therefore Justice Field concluded there could be no right to contribution between them at all. Furthermore he asserted that even if one party had already made payment towards their shared liability then still there would have been no cause of action because under California law only those who were actually liable for a debt can bring suit against others who may also be liable but have not yet contributed any portion thereof.
