In the case of William G. Cook v. John L. Moffat and Joseph Curtis, the Supreme Court was asked to decide whether a contract between two parties had been breached by one party in such a way that it would allow for damages to be awarded against them. The plaintiff argued that he had entered into an agreement with the defendants whereby they were obligated to pay him certain sums of money at specific times, but failed to do so when due, resulting in financial losses for him as well as other costs associated with trying to collect on his debt from them. The defendants countered that there was no breach of contract because they had not agreed upon any particular time frames or amounts owed; rather, they claimed their arrangement was more informal and thus did not constitute a legally binding agreement which could be enforced through legal action if violated. After considering both sides’ arguments, the court ultimately ruled in favor of the plaintiff and found that there indeed existed an enforceable contractual obligation between all three parties which required payment according to its terms; therefore awarding damages accordingly against those who failed to fulfill their obligations under said contract.

In the case of William G. Cook v. John L. Moffat and Joseph Curtis, Justice McLean delivered a dissenting opinion in which he argued that the plaintiff was entitled to recover damages from the defendants for breach of contract. He reasoned that although there had been no written agreement between them, their verbal agreement constituted an enforceable contract under common law principles because it was supported by consideration and mutual assent on both sides; thus, any subsequent repudiation or failure to perform on either side would be actionable as a breach of contract entitling the other party to damages. Furthermore, Justice McLean noted that even if there were some ambiguity regarding whether an actual contract existed between them due to lack of writing or certain terms not being specified clearly enough at the time they made their oral arrangement, this should have been resolved in favor of finding one since such contracts are favored by public policy considerations and serve important social interests such as encouraging trustworthiness among parties engaging in business transactions with each other.
