In the case of Brent and Others v. Davis, a dispute arose between two parties over an agreement to purchase land in Washington D.C. The plaintiffs argued that they had entered into an oral contract with the defendant for the sale of certain lots in Washington D.C., but that he had failed to fulfill his part of the bargain by not conveying title to them as promised. The Supreme Court found in favor of the plaintiffs, ruling that under common law principles, when one party has performed their obligations under a contract while another fails or refuses to do so, then damages may be awarded for breach of contract even if there is no written evidence proving its existence. This decision established important precedent regarding contracts made without formal documentation and was instrumental in protecting individuals from being taken advantage of due to lack of legal protection afforded by written agreements at this time period

In the case of Brent and Others v. Davis, Chief Justice Marshall delivered a dissenting opinion in which he argued that the court should not have granted an injunction to prevent the execution of a judgment against one of the defendants. He reasoned that such an action was beyond its jurisdiction as it had no authority over state courts or their judgments. Furthermore, Marshall noted that if this power were granted to federal courts then they would be able to interfere with any state court proceedings at will and thus undermine states’ rights. In conclusion, Marshall believed that granting injunctions in cases like these was unconstitutional and could lead to dangerous consequences for both federalism and judicial independence.
