In Allen & Another v. Withrow & Another, 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 the plaintiffs, Allen and another, and the defendants, Withrow and another, to purchase a tract of land. The plaintiffs had paid the defendants a portion of the purchase price, but the defendants refused to convey the land to the plaintiffs. The Supreme Court held that the contract was valid and enforceable. The Court found that the contract was supported by consideration, as the plaintiffs had paid the defendants a portion of the purchase price. The Court also found that the contract was not void for lack of mutuality, as the defendants had received consideration for the contract. The Court further held that the defendants were estopped from denying the validity of the contract, as they had accepted the consideration and had not repudiated the contract until after the plaintiffs had performed their part of the agreement. The Court concluded that the contract was valid and enforceable, and ordered the defendants to convey the land to the plaintiffs.
